Real-time artificial intelligence for solid-state lithium metal batteries.

ABSTRACT: Battery health often evolves from an initial regime of slow capacity decay to a fast decay regime, due to catastrophic electrochemical reactions to cause the battery failure. The signals of such failure, however, often emerge much earlier during cycling, an early detection of which may help prevent the failure through real-time adjustment of cycling procedures. Here we demonstrate the integration of machine learning module directly into electrochemical battery test stations to constantly detect the signals from battery current and voltage profiles, followed by reinforcement learning-based real-time adjustment of cycling procedures for greatly elongated battery lifetime. We use solid-state lithium metal batteries to demonstrate this proof-of-concept implementation of built-in intelligence f
