Cost-effective multi-cation doping and lithium concentration optimization in LaCl3-based solid electrolytes for enhanced performance of all-solid-state batteries
Multi-cation doping is an effective approach to improve the electrochemical performance of LaCl3-based solid-state electrolytes. Herein, equimolar Ca2+, Zr4+, and Ta5+ are introduced into the LaCl3 lattice with an optimized Li+ concentration to formulate xLiCl-(CaCl2·LaCl3·ZrCl4·TaCl5)0.25 (LCLZT-x). Structural analyse...
