Room Temperature Fabrication of Electrode-Solid Electrolyte Composite for All-Solid-State Rechargeable Lithium Batteries

Abstract

All-solid-state rechargeable lithium batteries (SSBs) have been expected as next generation energy storage devices with high energy density. Although thin-film SSBs with a few micron order electrode films prepared by vacuum technologies have been already commercialized, further improvements on their energy density inevitably require electrode-solid electrolyte composite electrodes over a few tens of micron order thickness. Here, we prepared the composite electrode by aerosol deposition at room temperature using electrode-solid electrolyte composite particles. Electrochemical properties of the composite will be discussed in addition to the densification process by the aerosol deposition.
