Cassette sheets Li-ion battery modules
The Cassette sheets frame structure hold the cells as sandwich way. We made plastic sheets which shape can exactly hold the cells and be pressed together and use the steel strips go through plastic sheets with two ends pressed by the screwed nuts. On the top area here are two of metal sheet bars for laser welding of cell tabs, bars have screws for further connection. If necessary here will be extra aluminum sheets with right shape to hold cells attach to plastic sheets, aluminum sheets can help cells improve the heat passion and enhance the strength of whole structure. Those kinds of structures are mainly used as quantity volume for big energy storage systems or big electric vehicles.
