Just Hype? New Study Challenges Core Assumptions About Solid-State Lithium Metal Batteries

LLZO-based solid-state batteries show limited energy density gains and face production challenges; hybrid electrolytes may be more viable A recent study examining garnet-type solid electrolytes for lithium metal batteries suggests that their energy density benefits may have been overestimated. The analysis shows that an all-solid-state lithium metal battery (ASSLMB) using lithium lanthanum zirconium oxide (LLZO) [...]
