Abstract
A battery including a plurality of cells housed in a battery container, wherein the battery container is formed of an insulating material and includes a plurality of housing portions formed by an inner wall portion of the battery container, each of the housing portions housing an associated one of the cells, and a conductive member for use in connecting the plurality of cells is embedded in a wall portion of the battery container. The housing portion has a shape conforming to an outer face of the cell and is in contact with the outer face of the cell.
Claims8
A battery comprising a plurality of cells housed in a battery container, the cell is a winding provided by winding a power-generating sheet around an axis, the power-generating sheet including a positive electrode sheet and a negative electrode sheet stacked with a separator interposed between them,
- wherein the battery container is formed of an insulating material and includes a plurality of housing portions formed by an inner wall portion of the battery container, each of the housing portions housing an associated one of the cells, and
- sandwiching members, each of the sandwiching members sandwiching an electrode portion of the winding, and a conductive member connecting the sandwiching members to each other for adjacent ones of the windings to connect the plurality of cells are embedded in a wall portion of the battery container.

A method of manufacturing a battery including a battery module housed in a resin battery container made of resin, comprising:
- a first step of connecting a plurality of cells through a conductive member to produce the battery module;
- and
- a second step of placing the battery module in a mold and injecting the resin into the mold having the battery module placed therein to perform injection molding of the resin battery container,
- wherein the injection molding is performed such that the conductive member is embedded in the resin at the second step.
