A team of materials scientists and engineers affiliated with several institutions in China has found that one of the major reasons solid-state lithium batteries fail over time is metal fatigue in the anode, which contributes to interface degradation and dendrite growth. In their paper published in the journal Science, the group describes how they studied dendrite growth in solid-state lithium batteries using scanning electron microscopy and what happened to their anodes over time.
