Macroscopically Ordered Piezo‐Potential in All‐Polymetric Solid Electrolytes Responding to Li Anode Volume Changes for Dendrites Suppression

Advanced Science, EarlyView.
A P(VDF‐TrFE) piezoelectric interlayer is developed for solid‐state Li‐metal batteries. Strategically orienting the piezoelectric field against Li+ migration redirects deposition from dendrite tips to planar regions through potential gradient steering. This results in uniform Li plating and preventing the growth of lithium dendrites.

Thermal Runaway Temperature Prediction of Lithium‐Ion Battery Under Extreme High‐Temperature Shock Using Experimental and Virtual Data

Advanced Science, EarlyView.
An integrated framework predicts lithium‐ion batteries (LIB) thermal runaway (TR) under extreme high‐temperature shock. By combining experimental data with the multiphysics‐generated virtual data, a hybrid deep learning approach is developed to accurately forecast temperature evolution for unseen scenarios.

Reaction Suppression Between a High‐Ni Cathode Material (NMC622) and Li7La3Zr2O12 on Co‐Sintering for Manufacturing Bulk‐Type All‐Solid‐State Batteries: A New Method and Its Mechanism

Advanced Science, EarlyView.
A bulk‐type all‐solid‐state battery is produced by co‐sintering the proprietary NMC622 and LLZ. This proprietary NMC622 can avoid the formation of impurity phases under co‐sintering. The reduced Ni2+ fraction in NMC622 and the presence of a self‐formed Li2CO3 surface layer result in this outcome. It is possible to realize a rechargeable all‐solid‐state
