Original Abstract Submitted
This application relates to a battery and an electric apparatus. A ratio of a capacity per unit area of a negative electrode of the battery to a capacity per unit area of a positive electrode of the battery is referred to as an NP ratio. The NP ratio of the battery is greater than or equal to 1.105, allowing the negative electrode potential corresponding to an upper limit of SOC of the battery to be higher than potential for crystalline phase formation, without BMS control or forced charging/discharging. This can alleviate or avoid battery memory effects, enabling maximum utilization of the capacity of the battery and improving energy efficiency of the battery.
