(Invited) All-Solid-State Batteries Using Li_7La_3Zr_2O_(12) Garnet Electrolyte Framework

摘要

All-solid-state batteries (ASSB) using LLZO (variants of Li_7La_3Zr_2O_(12)) garnet solid electrolyte with lithium metal anode potentially offer higher energy density and improved safety. Rational design of cell architecture as well as manufacturing scalability are key aspects to consider as the technology readiness level advances. A thick composite cathode layer attached to a thin solid electrolyte layer is desirable to obtain superior energy densities. Furthermore, the architecture within the composite cathode may be engineered to contain directional conduction paths of lithium ions or electrons for enhanced rate capabilities.
