Abstract
A battery cell has an electrode assembly in which at least a positive electrode layer, an electrolyte layer, and a negative electrode layer are alternatively laminated in this order, the electrode assembly being laminated predetermined number which is three or more. The laminated electrode assemblies include resin layers on end portions on both sides that are positioned in a direction orthogonal to a lamination direction. The resin layer has a scalene triangle-like first inclined portion and a scalene triangle-like second inclined portion.

A battery cell comprising:
- an electrode assembly in which at least a positive electrode layer, a electrolyte layer, and a negative electrode layer are alternatively laminated in this order, the electrode assembly being laminated predetermined number which is three or more,
- wherein the laminated electrode assemblies include resin layers on end portions on both sides that are positioned in a direction orthogonal to a lamination direction, and
- the resin layer has a scalene triangle-like inclined portion.
A method for coating a battery cell having an electrode assembly in which at least a positive electrode layer, a electrolyte layer, and a negative electrode layer are alternatively laminated in this order, the electrode assembly being laminated predetermined number which is three or more,
- wherein the electrode assemblies are laminated together,
- a resin is applied to positions offset with respect to a center in a lamination direction on end portions of the laminated electrode assemblies to provide resin layers on the end portions on both sides that are positioned in a direction orthogonal to the lamination direction of the electrode assemblies,
- the resin layers are formed on the end portions to be capable of insulating, and inclined portions are formed in the resin layers.
