Performance Enhancement of the Li6PS5Cl‐Based Solid‐State Batteries by Scavenging Lithium Dendrites with LaCl3‐Based Electrolyte

in symmetric cells, and the cyclability gets extended from 10 cycles to >200 cycles at the cycling rate of 0.5 C and 30 °C in Li|electrolyte|NCM721 full cells. The enhancing reasons are assigned to the capability of LTLC to scavenge lithium dendrites, forming a passive layer of Ta, La, and LiCl.
