DOE Award Aims To Accelerate Progress Of Zero Emission Vehicles |

Cars and trucks powered by fossil fuels are a leading cause of air pollution and carbon emissions. According to the United States Environmental Protection Agency, transportation is the main contributor to greenhouse gas emissions. To help combat this, the US Department of Energy (DOE) is working to decarbonize the transportation sector.

A research group led by Esther Takeuchi, distinguished professor in the Department of Materials Science and Chemical Engineering at Stony Brook received an award of more than $ 2.2 million, as part of a DOE initiative to facilitate new technologies to reduce CO2 emissions from passenger cars and light and heavy trucks. In addition to researchers from Stony Brook, the group will also include participants from Brookhaven National Laboratory (BNL) and Brown University.

Takeuchi will be the principal investigator. The co-researchers include Amy Marschilok, associate professor in the chemistry department, Kenneth Takeuchi, Distinguished Teaching Professor in the chemistry department, Carlos Colosqui, associate professor in the Department of Mechanical Engineering, three scientists from Brookhaven National Laboratory and a full professor from Brown University

Esther Takeuchi and Amy Marschilok are jointly appointed to SBU and Brookhaven Lab.

Entitled “Local electrolytes with high concentration of fluorinated esters for the operation of Li-ion batteries in extreme conditions”, the initiative will develop electrolytes for the operation of lithium-ion (Li-ion) batteries for operation in extreme conditions. extremes of fast charging, a wide temperature range and severe abuse.

“This project will establish a new class of electrolytes containing fluorinated ester solvents,” Takeuchi said. “Approaching it this way, we will enable improved cycling behavior under multiple extreme conditions to meet the needs of current and planned lithium-ion (Li-ion) battery applications. “

“The Brookhaven National Laboratory makes a significant contribution to clean energy initiatives,” said Jim Misewich, Brookhaven Lab Associate Laboratory Director for the Energy and Photon Sciences Department. “This new program will address some of the scientific challenges associated with batteries for electric vehicles. It is also an exceptional example of collaboration where scientists from the Brookhaven National Laboratory will interact closely with professors and young researchers from Stony Brook University and Brown University. We are delighted to participate in this opportunity.

Li-ion batteries are rechargeable and are commonly used for portable devices and electric vehicles. Batteries are gaining popularity for military and aerospace applications.

The objectives of the project include the characterization of the transport and stability of new electrolytic systems; evaluate the electrochemical behavior under reference and extreme conditions; and optimization of electrochemical behavior under extreme conditions by variation of composition.

“In partnership with industry and leading research universities, DOE’s investment in these 24 projects will create technologies that will reduce greenhouse gas emissions from vehicles and strengthen America’s competitiveness in the global marketplace. clean energy, ”said Energy Secretary Jennifer M. Granholm.

The DOE awarded a total of $ 60 million. Stony Brook joins 23 other research organizations nationwide to advance the R&D needed to help decarbonise the transportation sector.
