Abstract
Disclosed are batteries and electrical apparatuses. Non-faradaic capacitance of the negative electrode plate is Cdl nF, the sphericity of the negative active material contained in the negative electrode plate is S, and Cdl and S satisfy 0.5≤Cdl×S≤5. By adjusting Cdl value and sphericity S, so that they are in the range of 0.5≤Cdl×S≤5, which can effectively reduce the specific surface area of the negative active material, increase the tap density, so that the negative electrode plate has a high tap density without causing overpressure phenomenon. Furthermore, the mechanical stress experienced by the negative active materials of the negative electrode plate during rolling is minimized, and the reaction area with the electrolyte is minimized, it has good liquid retention properties, thereby avoiding the occurrence of gas generation and swelling, so that the batteries have excellent rate performance and cycle performance.
