New electrolyte for safer, more stable solid-state batteries

Researchers in Japan have discovered a stable, highly conductive material that can be used as electrolyte for solid-state lithium-ion batteries. The material's ionic conductivity is said to be higher than any previously reported oxide solid electrolytes, with a wide operating temperature range. All-solid-state lithium-ion batteries offer enhanced safety and energy density compared to their liquid electrolyte counterparts, but challenges associated with solid electrolyte, such as lower conductivity and insufficient electrode-electrolyte contact, remain one of the key hurdles on the technology's ...
