ORNL team tailors the structure of carbon black from waste tires to create higher performance carbon anode material for Li-ion batteries
August 28, 2014
Researchers at Oak Ridge National Laboratory (ORNL) have tailored the microstructural characteristics of carbon black recovered from discarded tires to produce a higher performance, low-cost carbon anode material for Li-ion batteries.
Electrochemical studies reported in their paper published in the journal RSC Advances showed that the recovered-carbon-based anode had a a reversible capacity of nearly 390 mAh/g of carbon anode after 100 cycles—exceeding the best properties of commercial graphite. Researchers attribute this to the unique microstructure of the tire-derived carbon. Anodes made with the sulfonated tire-rubber-derived carbon and a control tire-rubber-derived carbon exhibited an initial coulombic efficiency of 71% and 45%, respectively.
DOE to award more than $55M to 31 projects for plug-in and efficient vehicle technologies; Delphi receives $10M to further GDCI
August 14, 2014
The US Department of Energy (DOE) is awarding more than $55 million to 31 new projects to accelerate research and development of vehicle technologies that will improve fuel efficiency and reduce costs under a program-wide funding opportunity announced in January. (DE-FOA-0000991, earlier post.) These new projects are aimed at meeting the goals and objectives of the President’s EV Everywhere Grand Challenge (19 projects), as well as improvements in other vehicle technologies such as powertrains, fuel, tires and auxiliary systems (12 projects).
The largest single award ($10 million) goes to Delphi Automotive Systems to further the development of its Gasoline Direct-Injection Compression Ignition (GDCI) low-temperature combustion technology (earlier post) that provides high thermal efficiency with low NOx and PM emissions. The largest number of awards (9) in a single area of interest goes to developing beyond Li-ion battery technologies.
DOE to award $49.4M for advanced vehicle technologies research; meeting Tier 3 emissions
January 22, 2014
The US Department of Energy (DOE) will award $49.4 million to projects to to accelerate research and development of new vehicle technologies. The new program-wide funding opportunity (DE-FOA-0000991) (earlier post), was announced by Energy Secretary Ernest Moniz at the Washington Auto Show.
The funding opportunity will contains a total of 13 areas of interest in the general areas of advanced light-weighting; advanced battery development; power electronics; advanced heating, ventilation, air conditioning systems; advanced powertrains (including the ability to meet proposed EPA Tier 3 tailpipe emissions standards); and fuels and lubricants. These areas of interest apply to light, medium and heavy duty on-road vehicles.
DOE to issue FY14 Vehicle Technologies program-wide funding opportunity announcement
December 20, 2013
The Department Of Energy (DOE), Office of Energy Efficiency and Renewable Energy (EERE) intends to issue, on behalf of its Vehicle Technology Office (VTO), a program-wide Funding Opportunity Announcement (DE-FOA-0000991) for fiscal year 2014 on or about January 2014. The advance notice (DE-FOA-0001053) is to alert interested parties of the coming FOA.
The areas of interest outlined in the notice of intent (NOI) fall into two broad categories: technologies to advance plug-in electric vehicles; and technologies to improve fuel efficiency, including dual-fuel, fuel properties (e.g., high octane fuels), and advanced powertrain work.
Bridgestone unveils 2nd gen air-free tire; lower rolling resistance, improved load-bearing and performance

Bridgestone Corporation unveiled its second-generation “Air Free Concept (Non-Pneumatic) Tire” at the Tokyo Motor Showin November. (Earlier post.) The new design features improved load-bearing capabilities, environmental design and driving performance. The latest improvements bring Bridgestone one step closer to a viable, commercially available air-free tire, the company said.
Bridgestone, headquartered in Tokyo, originally announced its development of a non-pneumatic concept tire that could prove to be a viable and more environmentally-friendly alternative to conventional tires in the future in November 2011, and displayed the first version of the concept at the Tokyo Motor show that year.
Axens, IFPEN and Michelin launch research partnership on synthetic rubber production channel using biomass; €52M over 8 years
November 11, 2013

Axens, IFP Energies nouvelles (IFPEN) and Michelin have launched a plant chemistry research partnership that aims to develop and bring to market a process for producing bio-sourced butadiene, or bio-butadiene. Butadiene is a chemical intermediate derived from fossil resources that is used in the production of synthetic rubber. Some 60% of global output is for the tire industry.
In response to the need to find sustainable alternative sourcing channels for elastomers, the BioButterfly process will make it possible to produce innovative, more environmentally-friendly synthetic rubber. The bio-butadiene produced will support continued innovation in procuring high performance rubber for tires.
Fraunhofer and Continental building pilot system to extract Russian dandelion rubber for tires
October 28, 2013
Researchers from the Fraunhofer Institute for Molecular Biology and Applied Ecology IME, in collaboration with Continental, are building a pilot system to extract rubber from the Russian dandelion for making tires. Working jointly with industry and science, the IME scientists have optimized the cultivation and production engineering for dandelion rubber over the past few years.
The joint project officially started at the beginning of October. The goal is to develop the production process over the next five years so that Continental can manufacture tires made from dandelion rubber; first prototype test tires made with blends from dandelion rubber are scheduled to be tested on public roads over the next few years.
