Why the “Next-Gen” Lithium Metal Batteries Aren’t the Game-Changer We Hoped For
All-solid-state lithium metal batteries, particularly those using lithium lanthanum zirconium oxide (LLZO), fail to significantly outperform current lithium-ion technology. The gravimetric energy density of LLZO-based batteries nearly matches current lithium-ion levels, with minimal improvement. Challenges include bulkiness from LLZO’s density, manufacturing difficulties,
