Spontaneous formation of hollow structures in alloy anode crystals can improve battery stability

Green Car Congress

The problem has been that directly synthesizing these hollow nanostructures at the large scales needed for commercial applications is challenging and expensive. Antimony is relatively expensive and not currently used in commercial battery electrodes.

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

Green Car Congress

Our ultimate goal is to enable a commercially viable lithium metal battery. In contrast, when a commercial carbonate electrolyte is used, lithium deposits with a twisty, whisker-like morphology. —first author Chengcheng Fang, a materials science and engineering Ph.D. student at UCSD.
