Abstract

Official abstract text for this publication.

A main object of the present disclosure is to provide a method for producing a battery pack capable of efficiently curing an adhesive while suppressing a single battery from being heated. The present disclosure achieves the object by providing a method for producing a battery pack, the method comprising steps of: a preparing step; a storage step; and a filling step, wherein the preparing step is a step of preparing a laminated battery having a plurality of single batteries laminated in a thickness direction, the storage step is a step of storing the laminated battery in a battery case, the filling step is a step of fixing the laminated battery to the battery case by filling an adhesive in the battery case, wherein the adhesive contains a main agent, a curing agent, and a filler, the filling step includes a discharge process for discharging the adhesive from a nozzle and a heat treatment for heating the adhesive discharged from the nozzle by irradiating infrared rays, and the infrared rays are irradiated to the adhesive in the middle of discharge.

First claim

Opening claim text (preview).

What is claimed is: 1 . A method for producing a battery pack, the method comprising steps of: a preparing step; a storage step; and a filling step, wherein the preparing step is a step of preparing a laminated battery having a plurality of single batteries laminated in a thickness direction, the storage step is a step of storing the laminated battery in a battery case, the filling step is a step of fixing the laminated battery to the battery case by filling an adhesive in the battery case, wherein the adhesive contains a main agent, a curing agent, and a filler, the filling step includes a discharge process for discharging the adhesive from a nozzle and a heat treatment for heating the adhesive discharged from the nozzle by irradiating infrared rays, and the infrared rays are irradiated to the adhesive in the middle of discharge. 2 . The method for producing a battery pack according to claim 1 , wherein the filler is at least one of a black pigment and a black ceramic. 3 . The method for producing a battery pack according to claim 1 , wherein the heat treatment is a treatment in which the temperature of the adhesive is heated from room temperature to 40° C. or higher. 4 . A battery pack having a laminated battery and a battery case, wherein the laminated battery is housed in the battery case, the laminated battery has a plurality of single batteries laminated in a thickness direction, the laminated battery is fixed to the battery case by an adhesive, and the adhesive contains a main agent, a curing agent, and a filler. 5 . The battery pack according to claim 4 , wherein the filler is at least one of a black pigment and a black ceramic.
