Crossover Effects in Batteries with High‐Nickel Cathodes and Lithium‐Metal Anodes

It is well understood that cathode‐to‐anode crossover, especially of transition‐metal ions, can significantly impact the long‐term cycling of lithium‐ion batteries. The dissolved transition‐metal ions in lithium‐ion cells deposit on the graphite anode, disrupt the solid‐electrolyte interphase (SEI), and catalyze further side reactions. Meanwhile, crossover effects in lithium‐metal batteries have rarely been studied. This study is the first to...
