Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery technology, specifically to a high-safety lithium-ion battery. Background Technology

[0002] A lithium-ion battery is a rechargeable battery that primarily functions by the movement of lithium ions between the positive and negative electrodes. During charging and discharging, Li+ ions repeatedly insert and extract between the two electrodes: during charging, Li+ ions extract from the positive electrode, pass through the electrolyte, and insert into the negative electrode, leaving the negative electrode in a lithium-rich state; the reverse occurs during discharging.

[0003] For example, a Chinese patent discloses a high-safety lithium-ion battery, publication number CN210607498U, which includes a positive electrode, a negative electrode, a separator, and an electrolyte. The positive electrode includes a positive current collector, and the side of the positive current collector facing the negative electrode is sequentially coated with a blocking layer, a positive active material layer, and a separator layer; the side of the negative current collector facing the positive electrode is also sequentially coated with a blocking layer, a negative active material layer, and a separator layer. Compared with existing technologies, this invention can effectively cut off the current when the lithium-ion battery temperature is too high or a short circuit occurs, preventing internal short circuits and effectively controlling thermal runaway, thus increasing the safety performance of the lithium-ion battery. However, it cannot protect the battery surface, making the battery surface susceptible to external impacts during use. The lithium-ion battery has low safety protection, making it inconvenient for users to protect the battery and affecting normal use. Utility Model Content
