CPC H01M 10/443 (2013.01) [H01M 50/581 (2021.01); H01M 50/54 (2021.01); H01M 2200/10 (2013.01)] | 33 Claims |
1. An electrochemical device, comprising:
a substrate;
a first electrode adjacent to the substrate, the first electrode comprising electrode active material;
a second electrode comprising electrode active material, the second electrode having an opposite polarity of that of the first electrode;
a separator between the first electrode and the second electrode; and
an electrode tab portion electronically coupled to the first electrode, wherein the device is configured such that when the temperature of the substrate reaches a threshold temperature, at least a portion of the first electrode is no longer electronically coupled to the electrode tab portion due, at least in part, to a heat-induced change in volume of the substrate.
