Abstract

A battery module comprises an electrochemical cell including a first dielectric layer positioned on a first side of the cell, a first side plate in opposition to the first side, and a first adhesive layer positioned between the first side plate and the first side. The first dielectric layer defines a first window. The first adhesive layer is adhered to the first side plate and the first side through the first window. Another battery module comprises first and second cells, a base plate, a frame, and a first and second adhesive portion. The frame includes a beam positioned between the first cell and the second cell and is in engagement with a first side and a second side of the first and second cells, respectively. The first adhesive portion and the second adhesive portions are positioned between the base plate and the bottom surfaces of the cells.

Description

[0001] cross reference [0002] This application claims the benefit of US Provisional Patent Application No. 62 / 015,022, filed June 20, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates generally to battery cells, and more particularly to battery cells in battery modules and battery packs. Background technique [0004] A battery is an energy storage device for storing and supplying electrical energy, typically comprising one or more electrochemical cells that convert stored chemical energy into electrical energy. Multiple electrochemical cells are typically stacked together side by side and electrically connected together in series or parallel to form a battery pack or battery module. One or more battery modules can be secured to the battery pack base for installation on, for example, an electric or hybrid vehicle, allowing the vehicle to utilize energy from the battery modules to power the vehicle's mot...
