A novel method for energy efficient warmup of lithium-ion batteries from sub-zero temperatures using predictive control
by Paul N. Blumberg, PhD
Many of the machines and appliances that are in common use today require that their power be available immediately, regardless of adverse ambient conditions such as sub-zero temperatures. For example, on a 0 °F day, we expect to be able to start our cars or trucks, which may have cooled down to near ambient conditions, and proceed to use them in the same manner as if we were in more moderate climates. To accomplish this, engineers and scientists have worked hard to ensure that in extremely cold temperature environments, the engine oil does not become too viscous and that there are sufficient high volatility components in the fuel so that vaporization and ignition within the engine are possible on an almost instantaneous basis.
The same requirement holds true for battery-powered devices or vehicles. The Lithium-ion battery has emerged as the current “battery of choice” for automotive hybrid and electric vehicle applications. Over the last decade, significant improvements in its energy and power density have been made through research in all aspects of its fundamental electrochemistry and materials. Nevertheless, due to fundamental electrochemical factors, the availability of “instantaneous” power at temperatures below approximately 15 ˚F remains a challenge.

Nissan team gains insight into atomic structure of SiO using new methodology; potential benefit for Li-ion battery capacity
May 13, 2016
Using a new methodology, researchers in Japan—including colleagues from Nissan subsidiary Nissan Arc Ltd., a materials analysis and research center—have developed a heterostructure model of the atomic structure of silicon monoxide (SiO). The heterostructure model well explains the distinctive structure and properties of the material, which could play an important role in boosting the capacity of Li-ion batteries. An open-access paper on the work is published in Nature Communications.
Silicon (Si) is capable of holding greater amounts of lithium compared with common carbon-based materials; as such, it is a target of great focus as an anode material for higher capacity Li-ion batteries. However, in crystalline form, Si possesses a structure that deteriorates during charging cycles, ultimately impacting performance. However, amorphous SiO is resistant to such deterioration.

May 09, 2016
A team of scientists from the US Department of Energy’s (DOE) Brookhaven National Laboratory, the University of Pennsylvania, and the University of Maryland, College Park, has developed an electron microscopy technique to visualize—in real time and at high resolution—lithiation pathways in electrode materials.
The scientists used this advanced technique, described in an open-access paper in Nature Communications, to observe the discharge of a lithium-ion battery cell containing nanoparticles of magnetite—an inexpensive, nontoxic, high-conducting, high-energy-storage material. These discharge mechanisms were then correlated with the battery’s discharge rates. The team’s findings about how lithium migrates at the nanoscale could help improve the electrochemical performance of comparable electrode materials in lithium-ion batteries.

Argonne: longer-range BEVs may be almost as powertrain energy dense as gasoline vehicles by 2045
An analysis by a team at Argonne National Laboratory (ANL) has found that by 2045, some configurations of battery electric vehicles (BEV) could become almost as energy dense as a conventional vehicle. The team presented their paper at the recent 2016 SAE World Congress.
Hydrocarbon fuels (either fossil- or bio-derived) have high energy densities that are at least 100 times greater than that of a present day lithium-ion battery. Despite projected improvements in battery technology, this form of energy storage is still expected to be significantly less energy dense than gasoline even by 2045. However, the Argonne team argues, the energy density of storage medium (fuel or battery) should not be used as the sole criterion to compare conventional vehicles and BEVs. Rather, powertrain-level energy and power density will be better criteria to compare the propulsion technology used for BEVs and conventional vehicles, they suggest.
ORNL-led team identifies feature enabling fast ion conduction in solid electrolytes; new strategy for design
May 06, 2016
A team led by the Department of Energy’s Oak Ridge National Laboratory (ORNL) has used state-of-the-art microscopy to identify a previously undetected feature, about 5 billionths of a meter (nanometers) wide, in a solid electrolyte. The work experimentally verifies the importance of that feature to fast ion transport, and corroborates the observations with theory. The new mechanism the researchers report in Advanced Energy Materials points to a new strategy for the design of highly conductive solid electrolytes.
Using a solid electrolyte in a rechargeable battery is one of the most important factors in enabling safe, high-power, high-energy batteries, said first author Cheng Ma of ORNL, who conducted most of the study’s experiments. However, solid electrolytes typically suffer from low ionic conductivity, limiting their applications, Ma added.
CMU study concludes lithium market fluctuations unlikely to impact Li-ion battery prices significantly
May 05, 2016
A new study by a team from Carnegie Mellon University’s College of Engineering has found that even large increases in lithium prices are unlikely to increase significantly the cost of batteries or battery packs for end users such as vehicle manufactures or consumers—although some manufacturers may see reduced profit margins. The study comes against the backdrop of a more than doubling of global lithium prices over the last 6 months.
The Carnegie Mellon University researchers, whose study was published in the Journal of Power Sources, analyzed multiple lithium-ion battery chemistries and cell formats to see whether extreme lithium price variations would have a substantial impact. They found that the use of more expensive lithium precursor materials results in less than 1% increases in the cost of lithium-ion cells considered. Similarly, larger fluctuations in the global lithium price (from $0 to $25/kg from a baseline of $7.50 per kg of Li2CO3) do not change the cost of lithium-ion cells by more than 10%.

New silicon oxycarbide glass/graphene anode material; lightweight, high-capacity and long cycle life
April 11, 2016
Researchers at Kansas State University have developed a new high-performance Li-ion battery anode material combining silicon oxycarbide (SiOC) glass and graphene. The self-standing (i.e., no current collector or binder) anode material comprises molecular precursor-derived SiOC glass particles embedded in a chemically-modified reduced graphene oxide (rGO) matrix.
The porous reduced graphene oxide matrix serves as an effective electron conductor and current collector with a stable mechanical structure, and the amorphous silicon oxycarbide particles cycle lithium-ions with high Coulombic efficiency. The SiOC-rGO composite electrode delivers a charge capacity of ~588 mAh g−1electrode (~393 mAh cm−3electrode) at the 1,020th cycle and shows no evidence of mechanical failure.
PNNL study identifies one of the mechanisms behind Li-sulfur battery capacity fade; the importance of electrolyte anion selection
March 31, 2016
Researchers at Pacific Northwest National Laboratory (PNNL) investigating the stability of the anode/electrolyte interface in Li-Sulfur batteries have found that Li-S batteries using LiTFSI-based electrolytes are more stable than those using LiFSI-based electrolytes.
In their study, published in the journal Advanced Functional Materials, they determined that the decreased stability is because the N–S bond in the FSI− anion is fairly weak; the scission of this bond leads to the formation of lithium sulfate (LiSOx) in the presence of polysulfide species. By contrast, in the LiTFSI-based electrolyte, the lithium metal anode tends to react with polysulfide to form lithium sulfide (LiSx), which is more reversible than LiSOx formed in the LiFSI-based electrolyte.

Chinese researchers develop novel aluminum–graphite dual-ion battery
March 25, 2016
A team from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences has developed a novel, environmentally friendly low-cost battery. The new aluminum-graphite dual-ion battery (AGDIB) offers significantly reduced weight, volume, and fabrication cost, as well as higher energy density, in comparison with conventional LIBs.
The battery shows a reversible capacity of ≈100 mAh g−1 and a capacity retention of 88% after 200 charge–discharge cycles. A packaged aluminum–graphite battery is estimated to deliver an energy density of ≈150 Wh kg−1 at a power density of ≈1200 W kg−1—≈50% higher than most commercial lithium-ion batteries. A paper on the work is published in the journal Advanced Energy Materials.
Stanford team develops new simple approach for viable Li-metal anodes for advanced batteries
Lithium-metal anodes are favored for use in next-generation rechargeable Li-air or Li-sulfur batteries due to a tenfold higher theoretical specific capacity than graphite (3,860 mAh/g vs. 372 mAh/g); light weight and lowest anode potential. However, safety issues resulting from dendrite formation and instability caused by volume expansion have hampered development and deployment of commercially viable solutions.
A team at Stanford led by Prof. Yi Cui has now introduced a simple approach to address both issues by effectively encapsulating lithium inside a porous host scaffold using a facile melt-infusion approach. Uniformly confined within the matrix, the lithium creates a material that can deliver a high capacity of around 2,000 mAh/g (gravimetric) or 1,900 mAh/cm3 (volumetric) as stable anodes for Li-metal batteries. A paper on their work is published in Proceedings of the National Academy of Sciences (PNAS).

Researchers synthesize new Li-S cathode based on “carbon compartments”
February 10, 2016
Researchers from Texas A&M and Purdue have developed a new cathode material for Li-S batteries based on what they call carbon compartments (CCs)—conductive 3D carbon mesostructures that possess macro- and meso-pores that allow for high loading of sulfur nanoparticles and enhanced electrolyte-sulfur contact.
Fabricated using a scalable, single-step, and inexpensive solid-state synthesis, the 3D carbon architectures provide a conductive backbone for non-conducting sulfur particles and also effectively accommodate volume expansion during Li2S formation. Described in an open-access paper in the Journal of the Electrochemical Society, the CCs demonstrate around 700 mAh g−1 (at 47%-wt S) reversible capacity with high coulombic efficiency due to their unique structures.
Researchers 3D-print graphene composite aerogel microlattices for supercapacitors
Scientists at Lawrence Livermore National Laboratory and UC Santa Cruz have successfully 3D-printed periodic graphene composite aerogel microlattices for supercapacitor applications, using a technique known as direct-ink writing. The key factor in developing these novel aerogels is creating an extrudable graphene oxide-based composite ink and modifying the 3D printing method to accommodate aerogel processing.
The 3D-printed graphene composite aerogel (3D-GCA) electrodes are lightweight, highly conductive, and exhibit excellent electrochemical properties. Supercapacitors using these 3D-GCA electrodes with thicknesses on the order of millimeters display exceptional capacitive retention (ca. 90% from 0.5 to 10 A·g−1) and power densities (>4 kW·kg−1) that equal or exceed those of reported devices made with electrodes 10−100 times thinner. A paper on their work is published in the ACS journal Nano Letters.
Purdue team uses pollen grains as basis for carbon architectures for Li-ion anodes
February 08, 2016
A team at Purdue University has used pollens as the basis for carbon architectures for anodes in energy storage devices. As reported in an open-access paper in Nature’s Scientific Reports, Jialiang Tang and Vilas Pol converted bee pollen and cattail pollen grains into carbon microstructures through a facile, one-step, solid-state pyrolysis process in an inert atmosphere.
They air-activated the as-prepared carbonaceous particles at 300 °C, forming pores in the carbon structures to increase their energy-storage capacity, and then evaluated them as lithium-ion battery anodes at room (25 °C) and elevated (50 °C) temperatures. Findings showed the cattail pollens performed better than bee pollen. At a C/10 rate, the ACP (activated cattail pollen) electrode delivered high specific lithium storage reversible capacities (590 mAh/g at 50 °C and 382 mAh/g at 25 °C) and also exhibited excellent high rate capabilities.

Penn State team develops self-heating battery; addressing Li-ion energy loss in cold temperatures
Researchers at Penn State, with colleagues at EC Power, a Penn State spin-off, have developed a lithium-ion battery structure—the ‘all-climate battery’ (ACB) cell—that heats itself up from below 0 degrees Celsius without requiring external heating devices or electrolyte additives. The self-heating mechanism creates an electrochemical interface that is favorable for high discharge/charge power. Because only a fraction of the battery energy is used for self-heating, the ACB could address winter range anxiety issues for EV drivers, as well as proving useful for applications in robotics and space exploration, the team said in a paper published in the journal Nature.
The ACB warms itself up to 0 degrees Celsius within 20 seconds starting at -20 ˚C and within 30 seconds at -30 ˚C, consuming 3.8% and 5.5% of cell capacity, respectively. (EC Power projects that it will be able further to reduce the self-heating time from -20˚C to 0 ˚C to 5 seconds by 2017, and reduce energy consumption to 1%.) The self-heated all-climate battery cell yields a discharge/regeneration power of 1,061/1,425 watts per kilogram at a 50% state of charge and at -30 ˚C, delivering 6.4–12.3 times the power of state-of-the-art lithium-ion cells.
Argonne-led team demonstrates Li-air battery based on lithium superoxide; up to 5x Li-ion energy density
January 19, 2016
Researchers from Argonne National Laboratory, with colleagues in the US and Korea, have demonstrated a lithium-oxygen battery based on lithium superoxide (LiO2). The work, reported in the journal Nature, could open the way to very high-energy-density batteries based on LiO2 as well as to other possible uses of the compound, such as oxygen storage.
Lithium-air batteries form lithium peroxide (Li2O2)—a solid precipitate that clogs the pores of the electrode and degrades cell performance—as part of the charge−discharge reaction process. This remains a core challenge that needs to be overcome for the viable commercialization of Li-air technology. However, a number of studies of Li–air batteries have found evidence of LiO2 being formed as one component of the discharge product along with lithium peroxide (Li2O2).

Stanford team develops thermoresponsive film allowing fast and reversible shutdown of Li-ion batteries to prevent thermal runaway
January 13, 2016
Stanford researchers have developed a fast and reversible thermoresponsive polymer switching (TRPS) material that can be incorporated inside batteries to prevent thermal runaway. Batteries with the material can shut down under abnormal conditions such as overheating and shorting, and then can resume their normal function without performance compromise.
This material consists of electrochemically stable graphene-coated spiky nickel nanoparticles mixed in a polymer matrix with a high thermal expansion coefficient. The as-fabricated polymer composite films show high electrical conductivity of up to 50 S cm−1 at room temperature. Conductivity decreases within one second by seven to eight orders of magnitude on reaching the transition temperature and spontaneously recovers at room temperature. This approach offers 103–104 times higher sensitivity to temperature changes than previous switching devices, the researchers said in an open-access paper published in the new journal Nature Energy.
National labs researchers find simple procedure to improve performance of NMC cathodes in Li-ion batteries
January 12, 2016

Now, a team of scientists from the US Department of Energy’s (DOE) Brookhaven National Laboratory, Lawrence Berkeley National Laboratory, and SLAC National Accelerator Laboratory has found that using a simple technique called spray pyrolysis can help to overcome one of the biggest problems associated with NMC cathodes—surface reactivity, which leads to material degradation. An open-access paper on their work is published in the journal Nature Energy.
Chevrolet releases more details on Bolt drive unit and battery; one-pedal driving
January 11, 2016
Hard on the heels of the reveal of the production Volt EV at CES 2016 in Las Vegas earlier post), Chevrolet used the North American International Auto Show (NAIAS) in Detroit to release additional details on the battery and drivetrain of the new BEV. Engineers developed the Bolt EV’s propulsion system to offer more than an estimated 200 miles (based on GM estimates) and a sporty driving experience.
The Bolt EV’s drive system uses a single high capacity electric motor to propel the car. The engineering team designed the Bolt EV’s electric motor with an offset gear and shaft configuration tailored to meet efficiency and performance targets—most notably more than an estimated 200 miles of range. The motor is capable of producing up to 266 lb-ft (360 N·m) of torque and 200 hp (150 kW) of motoring power. Combined with a 7.05:1 final drive ratio, it helps propel the Bolt EV from 0-60 mph in less than seven seconds.
Penn State team develops highly crumpled nitrogen-doped graphene sheets as high-performance cathode for Li-sulfur batteries
January 08, 2016
Researchers at The Pennsylvania State University have synthesized highly crumpled nitrogen-doped graphene (NG) sheets with ultrahigh pore volume (5.4 cm3) and large surface area (1158 m2/g), which enable strong polysulfide adsorption and high sulfur content for use as a cathode material in Li-sulfur batteries. The wrinkled graphene sheets are interwoven rather than stacked, resulting in rich nitrogen-containing active sites.
Lithium–sulfur battery cells using these wrinkled graphene sheets as both sulfur host and interlayer achieved a high capacity of 1227 mAh/g and long cycle life (75% capacity retention after 300 cycles) even at high sulfur content (≥80 wt %) and sulfur loading (5 mg sulfur/cm2). A high capacity of 1082 mAh/g was still achieved with an ultrahigh sulfur content of 90 wt %, and a capacity of 832 mAh/g was retained after 200 cycles. Areal capacity was 5 mAh/cm2. A paper on their work is published in the ACS journal Nano Letters.
