Problems solved by technology

The second reason is that in order to form a pouch around the electrochemical cell, the package must be sealed on at least three sides
[0015] From the above it is clear that the viable path to small, thin, high capacity electrochemical cells is limited by packaging

Abstract

A hermetic seal for electrochemical cells. The seal is formed between first and second electronically conductive barrier members. The seal is formed by a cold weld between the first and second barrier members. At least one of the first barrier member and the second barrier member are configured to function as current collectors.

Description

[0001] Cross References to Related Applications [0002] This application relates to and claims the benefit of commonly owned, co-pending U.S. Provisional Patent Application Serial No. 62 / 756,959, entitled "ENCLOSURES FORELECTROCHEMICAL CELLS," filed November 7, 2018, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to improved packaging for electrochemical cells and more particularly batteries and electrochemical double layer capacitors. Background technique [0004] There is a huge need for electrochemical energy storage systems that store more energy per weight and volume. Of these, the amount of energy stored per volume is significantly more important for smaller energy storage devices for personal electronics, biomedical applications, and other technologies. Most efforts to optimize the volume of energy storage devices have focused on the active materials, especially in the case of lithium batter...
