Abstract
The present invention addresses the problem of obtaining a battery capable of achieving a uniform temperature among a plurality of battery cells in a simple configuration while achieving size and weight reductions, and a battery module using the battery block. The battery block of the present invention has a structure such that a pair of end plates is disposed at both ends of a plurality of battery cells in an arranged direction; first spacers are disposed between the plurality of battery cells; and second spacers are disposed between the battery cells and the end plates. The first spacers have a space for allowing a flow of cooling gas. The second spacers block the flow of the cooling gas between the battery cells and the end plates and have a thermal insulating property for suppressing heat transmission between the battery cells and the end plates.
