Resumen de: US20260171519A1
An ECU acquires the SOC, SOH, and degradation time. An anode degradation coefficient is calculated from the SOH and an effective temperature, and a time degradation coefficient is calculated from the degradation time and the effective temperature. The smaller of the anode degradation coefficient and the time degradation coefficient is calculated as an overall degradation coefficient, and an initial input current limit value is calculated from the SOC and the effective temperature. An input current limit value is calculated by multiplying the initial input current limit value by the overall degradation coefficient. The input current of the battery is controlled so as not to exceed the input current limit value. When an anode degradation factor (= SOH × anode resistance increase rate) is greater than 1, the anode degradation coefficient is set to the reciprocal of the anode degradation factor.

A secondary battery and an electric device, relating to the technical field of secondary batteries. NaaMbNicFedMneO2 is used as a positive electrode active material. A propylene carbonate compound is used as an electrolyte solvent, wherein the activity of H in the propylene carbonate compound is low, such that the propylene carbonate compound has good oxidation resistance, thereby inhibiting the formation of RH+ to a certain extent, and achieving the effect of inhibiting gas generation from reduction at a negative electrode. Moreover, when a nickel-iron-manganese layered metal oxide is used as the positive electrode active material, a cyclic sulfate compound is used as an additive, so that a CEI film can be formed on a positive electrode, thereby inhibiting gas generation from the oxidative decomposition of an electrolyte by a sodium layered oxide, and reducing the formation of RH+. Moreover, since the reduction potential of the cyclic sulfate compound is higher than that of the propylene carbonate compound, the cyclic sulfate compound can form an SEI film before the reduction of the propylene carbonate compound at the negative electrode, thereby inhibiting the formation of the oxidation product RH+ and gas generation from reduction of the electrolyte solvent at the negative electrode.

A secondary battery and an electric device, relating to the technical field of secondary batteries. When a positive electrode active material is a nickel-iron-manganese layered metal oxide, a cyclic sulfate ester compound is capable of forming films on both a positive electrode sheet and a negative electrode sheet, and a CEI film formed on the positive electrode sheet suppresses a side reaction between the nickel-iron-manganese layered metal oxide and a non-aqueous electrolyte, thereby improving the cycle performance of the secondary battery and reducing gas generation during high-SOC storage. Moreover, a difluorooxalatoborate salt compound, which has a higher reduction potential than the cyclic sulfate ester compound, is selected, the difluorooxalatoborate salt compound is capable of preferentially forming an inorganic SEI film on the surface of a negative electrode sheet prior to the cyclic sulfate ester compound, and the inorganic SEI film is distributed in a dot-like manner to occupy some of surface active sites of a negative electrode active material, thereby reducing extensive formation of an organic polymer-type SEI film by the cyclic sulfate ester compound on the negative electrode sheet, so that the overall impedance of the SEI film is low, reducing the DCR of the secondary battery, and isolating the electrolyte from a negative electrode to suppress gas generation caused by reduction at the negative electrode.
