Garnettype solid electrolytes, such as Li La 3 Zr Ta O 12 (LLZTO), are promising materials for solidstate batteries, but processing remains a challenge, in part due to the high sintering temperature required for densification. This temperature can be lowered by decreasing the initial particle size via solventassisted ball milling, but the relationship between solvent choice ...
