As the landscape of energy harvesting evolves, so do the devices that store that energy. According to researchers from Toyohashi University, all-solid-state lithium rechargeable batteries are at the top of the list of promising future energy storage technologies due to their high energy density, safety, and extreme cycle stability.
ECS member Yoji Sakurai and a team from the university’s Department of Electrical and Electronic Information Engineering recently published a paper detailing their development to advance the all-solid-state batteries, which pushes past barriers related to electrochemical performance.

This from Toyohashi University:
[The researchers] developed a garnet-type, fast ionic conducting oxide as the solid electrolyte for an all-solid-state battery. Using the developed material, the rechargeable all-solid-state battery was fabricated and tested. These results indicate that the developed LLBZTO garnet can be used as a solid electrolyte in an all-solid-state battery and contribute to the realization of a very safe rechargeable battery for large-scale power sources, even though additional investigation is needed in order to enhance the performance of solid-state batteries. The researchers carried out further study to realize solid-state batteries with high energy density.
