Abstract
The present invention provides an electrochemical cell of either a primary or a secondary chemistry housed in a casing having opposed major side walls of a contoured shape.
Claims15
An electrochemical cell, which comprises:
- a) a negative electrode;
- b) a positive electrode;
- c) a casing housing the negative and positive electrodes, wherein the casing comprises a first portion having a first major side wall extending to and meeting with a first surrounding side wall and a second portion having a second major sidewall extending to and meeting with a second surrounding side wall and wherein the first and second portions are mated to each other with the first surrounding side wall contacting the second surrounding side wall;
- and
- d) an electrolyte provided in the casing to activate the negative and positive electrodes.
