Lithium-ion battery fires spark global recall of 68,000 EVs amid over charging concerns

Tue, 11/17/2020 - 09:38 -- Paul Crompton

The root cause of fires that pushed General Motors to recall 68,667 Chevrolet Bolt electric vehicles is unknown but “could be” related to overcharging the high voltage lithium-ion batteries produced in South Korea by LG Chem. 

Concerns the batteries could catch fire when fully charged has led the US federal vehicle safety agency National Highway Traffic Safety Administration (NHTSA) to recommend charging up to 90% capacity until a software update is completed.

Anode material opens path to fast charging lithium-ion batteries

Fri, 03/27/2020 - 11:16 -- Paul Crompton

US scientists could provide insights into battery materials that allow the rapid charging of electric vehicles after making observations on how ions move in lithium titanate electrode material.

A team led by the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and Lawrence Berkeley National Laboratory captured, in real time, how lithium ions move in the material (made of lithium, titanium, and oxygen).

German project aims to boost EV lithium-ion battery size and manufacturing abilities

Tue, 03/24/2020 - 12:12 -- Paul Crompton

Researchers at the Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) in Germany to bridge the gap from prototype demonstration to industrial mass production of large-format lithium-ion cells.

Launched earlier this month, the ZellkoBatt project will look at reducing the costs of components and digitising manufacturing processes for cells to be used in automotive applications.

The research will include large-format pouch and PHEV-2 cells up to 80Ah and 21700 cylindrical cells.
