Document Type and Number:
Japanese Patent JP7053162
Kind Code:
B2
Abstract:
Provided is a laminated battery module that is capable of imparting a minimum required restraining load to a battery laminate at a low temperature and a low charging rate, while also withstanding the load on the battery laminate at a high temperature and a high charging rate, without increasing the size of the restraining member. A laminated battery module 100 includes a battery laminate 15 containing one or more unit cells, a restraining member 20 containing a pair of end plates 21 located on both ends of the battery laminate 15 in the direction of lamination and tensioning members 22 that fasten the pair of end plates 21 mutually, and an elastic member 30 located between the pair of end plates 21; wherein, the elastic member 30 is composed of a material that undergoes a decrease in the elastic modulus thereof accompanying a rise in temperature from −30° C. to 80° C.
