Title: ALL-SOLID-STATE LITHIUM ION SECONDARY BATTERY
Abstract:
This all-solid-state lithium ion secondary battery is configured such that: a plurality of electrode layers, in each of which a collector layer and an active material layer are laminated, are laminated with a solid electrolyte layer being interposed therebetween; the collector layer contains Cu; and a Cu-containing region is formed in a grain boundary that is present in the vicinity of the collector layer among grain boundaries of grains that constitute the active material layer.
