Title:
BATTERY AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/082139
Kind Code:
A1
Abstract:
Disclosed in the present application are a battery and an electric device. The battery comprises at least one first battery cell and at least one second battery cell, wherein the internal resistance of the first battery cell is greater than the internal resistance of the second battery cell, and the heat transfer rate of the first battery cell is less than the heat transfer rate of the second battery cell. The battery is provided with a first battery cell that has a relatively large internal resistance and thus generates more heat; moreover, the first battery cell also has a relatively low heat transfer rate, such that the first battery cell has a heat preservation function and also provides a good heat production performance, which facilitates a reduction in the influence of an external low temperature on the battery, thereby ameliorating the problem of the capacity of the battery being obviously reduced at a low temperature.
