CURVED BATTERY CONTAINER

摘要

A curved container for electrochemical battery cells manufactured with an open side into which the battery cells are placed along with a resilient structure such that when the lid is placed on the container and attached/sealed, the battery cells are sealed in the container and preloaded against the large top and bottom surfaces of the container. Electrical contacts feed through one edge of the container to enable the electrical power generated by the cells to be safely accessed, and the cells can be safely charged without external atmospheric leaks into the container, or gases generated during battery use to escape. The containers can be stacked on edge next to each other as a stack but without the need to compress the stack to maintain battery cell compression, which enables a container to be easily replaced without having to dissemble the stack.

主权项

1. An electrochemical cell, comprising:
a container including a first portion and a second portion and defining an inner volume therebetween, the first portion including a first surface having a first radius of curvature, the second portion including a second surface having a second radius of curvature, the second surface opposite the first surface and the second radius of curvature different than the first radius of curvature; and an electrochemical cell stack disposed in the inner volume, the electrochemical cell stack including an anode, a cathode and a separator disposed between the anode and the cathode.
