| Abstract Scope |
The use of lithium (Li) metal as an anode could enable high specific energy for solid-state batteries (SSBs). Regulating the dynamic interface between the Li metal and the solid electrolyte separator during cell operation for more even Li plating and stripping is key to improving cycling performance. In this presentation, we discuss an anodic interlayer strategy to improve SSB performance by using a dry-compressible conductive and lithiophilic composite. The dry compressibility of the composite is enabled using holey graphene, a unique carbon nanomaterial. The interlayer can be simultaneously formed with the cathode and the separator layers in a single dry compression step during SSB cell fabrication enabling consistent cell performance under low stack pressure conditions. The interlayer could be used with or without Li metal anode, with cells of either configuration exhibiting excellent performance. The fabrication and performance of the interlayer and the SSB cells will be presented and discussed. |
