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.

AI predicts method for fast-charging EVs while minimising lithium-ion battery degradation

Fri, 02/28/2020 - 12:13 -- Paul Crompton

Artificial intelligence could have given clues on the best method for fast-charging electric vehicles thanks to a study at the US’ Stanford University.

Instead of charging at the highest current at the beginning of the charge, the computer’s algorithm suggested using the highest current in the middle of the charge.
