Preparation and Characterization of Sol-Gel-Driven LiLa₃Zr₂O Solid Electrolytes and LiCoO₂ Cathodes for All-Solid-State Lithium-Ion Batteries.

In the current study, we prepared a LiLa₃Zr₂O ((Al, Ta) LLZO) powder doped with 0.2 mol of Al and Ta using the sol-gel method and subsequently used it to fabricate solid electrolyte pellets. In pellets with lithium content of 6.
