Front Cover: Structural Design of Composite Polymer Electrolytes for Solid‐state Lithium Metal Batteries (ChemNanoMat 11/2021)

The performance of solid composite electrolyte is greatly influenced by its components and corresponding structural design. The relative effects of inorganic components on the electrolyte ionic conductivity are as follows: inert particles(P)<active particles (P)<inert ceramic nanowires (W) < active ceramic nanowires (W)<inert 3D ceramic framework (F) <active ceramic 3D skeleton≈vertical structure (V). More importantly, the electrolyte/electrode interface issues (INT), including interface physics and interface chemistry, play a significant role in the electrochemical performance of the assembled solid-state lithium metal batteries.
