US 2024/0258666 A1 · BATTERY AND METHOD FOR MANUFACTURING BATTERY

Abstract

A battery according to the present disclosure includes a power-generating element having a plurality of parallel laminates electrically series-connected and laminated. The parallel laminates each include an odd number of battery cells electrically connected in parallel and laminated. The battery cells each include an electrode layer, a counter electrode layer, and a solid electrolyte layer positioned therebetween. The battery further includes: an electrode insulating member covering the electrode layer on a first side surface of each parallel laminate; a counter electrode connector that covers the first side surface and the electrode insulating member and is electrically connected to the counter electrode layer in each parallel laminate; a counter electrode insulating member covering the counter electrode layer on a second side surface of each parallel laminate; and an electrode connector that covers the second side surface and the counter electrode insulating member and is electrically connected to the electrode layer in each parallel laminate.
