Реферат: A metal ion cell that includes a positive electrode with a cathode active material configured to store and release metal ions; a negative electrode with an anode active material that operates at a potential that is not less than 0.6 volts (V) versus Li/Li+; and an electrolyte that incorporates one or more (e.g., lithium) metal salts and a solvent mixture that includes 3-methoxypropionitrile (MPN) and at least one linear carbonate. The MPN in the electrolyte may have a mass ratio of ≥ 0.1 as compared to the at least one linear carbonate. The at least one linear carbonate includes one or more of dimethyl carbonate (DMC), diethyl carbonate (DEC), or ethyl methyl carbonate (EMC). The solvent mixture may also include a mixture of carbonates, such that the mass percentage of the linear carbonate ranges from 10% to 90% compared to the overall mass of the mixture of carbonates.
Lithium ion cells with high performance electrolyte and silicon oxide active materials achieving very long cycle life performance
