Study identifies main culprit behind lithium metal battery failure; counters conventional wisdom

Green Car Congress

For example, in an electrolyte specially designed by Meng’s collaborators at General Motors, lithium deposits as dense, column-shaped chunks. The answer has to do with how lithium deposits on the anode when the cell is charging. Some electrolytes cause lithium to form micro- and nanostructures that boost cell performance.
