Problems solved by technology

However, as the demand for high-rate charging and discharging in these applications increases, the original overcharge protection device for lithium-ion batteries cannot meet the existing overcharge protection requirements, especially in high-rate discharges (for example, 2C charging, 8C discharge, etc., where C represents the ratio unit relative to the nominal capacity of the lithium-ion battery), it will cause the wrong start of the overcharge protection device, resulting in the problem of unable to discharge normally, and the cost of some overcharge protection devices is relatively high. high

Abstract

The present application discloses an electric core, which comprises: a tab and a fuse assembly electrically connected to the tab; wherein, the fuse assembly includes at least one of conductive glue or alloy. Through the above technical solution of the present application, it is possible to form effective overcharge protection for the battery cell under the condition of high current charging and discharging, without affecting the normal operation of the battery cell, and the cost is low.

Description

technical field [0001] The present application relates to the field of energy storage, and more specifically, to a battery cell. Background technique [0002] Lithium-ion battery is an efficient energy storage device, which has the advantages of high voltage, high specific energy and long cycle life. Lithium-ion batteries have been widely used in electronic products (such as mobile phones, notebook computers, and digital cameras, etc.), electric vehicles, electric tools, and energy storage power stations. However, as the demand for high-rate charging and discharging in these applications increases, the original overcharge protection device for lithium-ion batteries cannot meet the existing overcharge protection requirements, especially in high-rate discharges (for example, 2C charging, 8C discharge, etc., where C represents the ratio unit relative to the nominal capacity of the lithium-ion battery), it will cause the wrong start of the overcharge protection device, resultin...
