U Texas Austin team finds P2S5 electrolyte additive enables use of Li2S bulk particles for high-capacity cathodes in lithium-sulfur batteries; ~800 mAh/g

19 December 2014

Researchers at the University of Texas at Austin, led by Prof. Arumugam Manthiram, have found that using phosphorus pentasulfide (P2S5) as an electrolyte additive enables the direct use of commercially available bulk Li2S particles as high-capacity cathode materials for rechargeable Li−S batteries, without intricate synthesis or application of a high charging cut-off voltage that deteriorates the electrolyte stability and safety.

The ability to use commercially available bulk particles could significantly decrease the manufacturing cost of Li−S batteries with a LiS cathode. In a paper published in the ACS Journal of Physical Chemistry Letters, the team suggested that this strategy is both of significance for the safe and effective use of Li2S as a cathode material and as a promising step toward the low-cost fabrication of metallic-lithium-free Li−S batteries.

A team led by researchers at Chungnam National University (S. Korea) has developed a novel high-voltage electrolyte additive, di-(2,2,2 trifluoroethyl)carbonate (DFDEC), for use with the promising lithium-rich layered composite oxide high-energy cathode material xLi2MnO3·(1-x)LiMO2 (M = Mn, Ni, Co).

In a study reported in the Journal of the Electrochemical Society, the team, led by Professor Seung-Wan Song, operated a 0.6Li2MnO3·0.4LiNi0.45Co0.25Mn0.3O2 (Li1.2Mn0.525Ni0.175Co0.1O2, LMNC) cathode at 2.5–4.8 V with 5 wt% of the fluorinated linear carbonate DFDEC as an additive. The cathode with DFDEC-enhanced electrolyte outperformed that in electrolyte only, delivering a high capacity of 250 mAhg−1 with an excellent charge-discharge cycling stability at the rate of 0.2C. A full cell based on the LMNC cathode and graphite anode successfully demonstrated doubled energy density (∼278 Wh kg−1) compared to ∼136 Wh kg−1 of a commercialized cell of graphite/LiCoO2 as well as an excellent cycling stability.

Rice U team uses new computational methodology to identify high capacity MOFs for on-board natural gas storage

18 December 2014

Researchers from Rice University, Lawrence Berkeley National Laboratory and UC Berkeley have developed a computational methodology to support the experimental exploration of potential high-capacity metal organic frameworks (MOFs) for use in on-board storage of natural gas. The advantages to using MOFs as a storage medium are many and start with increased capacity over the heavy, high-pressure cylinders in current use.

In a paper in the ACS Journal of Physical Chemistry C, they report identifying 48 materials with higher predicted deliverable capacity (at 65 bar storage, 5.8 bar depletion, and 298 K) than MOF-5—the currently best available for the natural gas storage application. The best material identified by the researchers has a predicted deliverable capacity 8% higher than that of MOF-5.

European automotive and automotive battery industries call for extension of the exemption of lead-based batteries from the EU ELV Directive

18 December 2014

The EU must continue to allow the use of lead-based batteries in vehicles as they are essential for the needs of future generations of European cars, according to the automotive and automotive battery industries in Europe. Lead battery and car manufacturers have requested that the current exemption for lead-based batteries within the ELV Directive’s wider ban on lead in light-duty vehicles is maintained for at least another eight years.

The comments are part of the formal submission made by the industry group to EU regulators who concluded the public consultation phase of the review of the End of Life Vehicle (ELV) Directive this week. Following the consultation the Commission is expected to release its opinion in the first half of 2015.

Purdue process converts lignin in intact biomass to hydrocarbons for chemicals and fuels

18 December 2014

A team of researchers from Purdue University’s Center for Direct Catalytic Conversion of Biomass to Biofuels, or C3Bio, has developed a process that uses a bimetallic Zn/Pd/C catalyst to convert lignin in intact lignocellulosic biomass directly into two methoxyphenol products (phenols are a class of aromatic hydrocarbon compounds used in perfumes and flavorings) leaving behind the carbohydrates as a solid residue.

Lignin-derived methoxyphenols can be further deoxygenated to propylcyclohexane—a cycloalkane. Cycloalkanes are important components of not only traditional vehicle fuels such as gasoline and diesel, but also jet fuels, such as Jet-A/Jet-A1/JP-8.

PBL/JRC: Global CO2 emissions increase to new all-time record in 2013, but growth is slowing down

18 December 2014

Global CO2 emissions from fossil fuel use and cement production reached a new all-time high in 2013, according to the annual report “Trends in global CO2 emissions”, released by PBL Netherlands Environmental Assessment Agency and the European Joint Research Centre (JRC). This was mainly due to the continuing steady increase in energy use in emerging economies over the past ten years. However, emissions increased at a notably slower rate (2%) than on average in the last ten years (3.8% per year since 2003, excluding the credit crunch years).

This slowdown, which began in 2012, signals a further decoupling of global emissions and economic growth, which reflects mainly the lower emissions growth rate of China. China, the USA and the EU remain the top-3 emitters of CO2, accounting for respectively 29%, 15% and 11% of the world’s total. After years of a steady decline, the CO2 emissions of the United States grew by 2.5% in 2013, whereas in the EU emissions continued to decrease, by 1.4% in 2013.

Washington governor proposes slate of measures to curb GHG emissions & transition state to cleaner energy; cap-and-trade and EV incentives

17 December 2014

Washington Governor Jay Inslee announced a set of proposals to transition Washington to cleaner sources of energy and to meet greenhouse gas (GHG) emission limits adopted by the state Legislature in 2008. The proposals build on a comprehensive executive order issued by the governor in April.

Cap-and-trade. The proposed “Carbon Pollution Accountability Act” (CPAA) would create a new, market-based program that sets an annual limit CO2 emissions; major emitters will need to purchase “allowances” for their emissions. Each year, the number of available allowances will decline to ensure emissions are gradually reduced. The Governor’s office projects that the program will generate about $1 billion in the first year, and more thereafter, which will be used for transportation, education, tax relief for working families and other purposes.
