Volkswagen Group of America opened a large electric vehicle charge park at the Innovation and Engineering Center California (IECC) – Silicon Valley Campus. In addition to 11 existing charging stations on campus, a total of 51 new charging stations are now fully operable on the property and accessible to the public.

Too much ion flow causes anode materials to swell and then shrink during charge-discharge cycles, causing mechanical degradation that shortens battery life. The small test batteries we fabricated showed promising charge-discharge performance, so we would like to evaluate the materials in larger batteries. —Matthew McDowell.

The answer has to do with how lithium deposits on the anode when the cell is charging. Right: Porous, tortuous, whisker-like microstructure which lowers Coulombic efficiency.
