Abstract
Lithium-metal batteries (LMBs) are garnering attention as a next-generation battery technology that can surpass conventional Li-ion batteries in terms of energy density, but suffers from the safety issue and unstable cycling. Herein, we report a class of elastomeric electrolytes with a three-dimensional interconnected plastic crystal phase. The elastomeric electrolytes show a combination of mechanical robustness, high ionic conductivity, low interfacial resistance and high lithium-ion transference number. Moreover, the elastomer electrolytes enable stable operation of the full cells under constrained conditions delivering a high specific energy. Next, I will present the structure-property-electrochemical performance relationship of the elastomeric electrolytes in the LMBs. In the last part, I will introduce our recent work on polymer protective layers for enhancing the cyclability of lithium metal batteries.
