  • BATTERY ASSEMBLY AND PROCESSING METHOD AND APPARATUS THEREFOR, BATTERY CELL, BATTERY, AND POWER CONSUMING DEVICE
    Publication number: 20240079729
    Abstract: The present application provides an electrode assembly and a processing method and apparatus therefor, a battery cell, a battery, and a power consuming device. The electrode assembly includes: a cathode plate, an anode plate, and a separator, where the separator is configured to separate the cathode plate from the anode plate, a closed-pore portion is provided in part of the region of the separator, and the closed-pore portion is configured to block at least some ions de-intercalated from the cathode plate located on one side of the closed-pore portion from being intercalated into the anode plate located on the other side of the closed-pore portion. Heating the separator to form the closed-pore portion can reduce the occurrence of lithium precipitation.
