Development of a compact all-solid-state lithium secondary battery using single-crystal electrolyte: Towards realizing oxide-type all-solid-state lithium secondary batteries

All-solid-state lithium secondary batteries are attracting attention as a next-generation technology. To realize this technology, it is important to develop a new solid-state lithium-ion conductor. In this regard, we discuss the development of all-solid-state secondary lithium batteries using single-crystal solid electrolytes and the AD method.
