Abstract:
In general, the present disclosure is directed to forming lithium ion battery (LIB) cells with structure and chemistry that achieves formation of a solid electrolyte interphase (SEI) layer that allows for operating in relatively high ambient temperature environments, e.g., up to and exceeding 60° C., while significantly reducing self-discharge amounts, e.g., relative to other LIB cells formed with SEI layers measuring about 1-2 nanometers in thickness. For example, one non-limiting embodiment of the present disclosure enables a self-discharge amount for a LIB cell of 10% or less over a four (4) week period of time when operating at an ambient temperature of 60 degrees Celsius.
