Decoding Chemo‐Mechanical Failure Mechanisms of Solid‐State Lithium Metal Battery Under Low Stack Pressure via Optical Fiber Sensors

open access: yesAdvanced Materials, EarlyView.
By FBG sensing the Li/electrolyte interfacial stress in solid‐state battery, the Li metal anode failure reasons as dendrite‐induced uneven stress distribution at electrode/electrolyte interface are disclosed. A Li–Sn composite anode is demonstrated effective in stabilizing the interface mechanics and the solid‐state full cell performance at low stack ...
