Inventors include Huang, Xu; Wei, Xiaoliang; Tan, Yuangao; Wu, Shengben; and Xiang, Haibiao.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: The present invention relates to the technical field of secondary battery materials. Disclosed are a safety coating and the use thereof, an electrode sheet and a lithium-ion battery. By limiting the particle size of an inorganic filler in the safety coating, particle size grading is achieved, which enables the safety coating to have a compact structure, thereby reducing the probability of contact between positive and negative electrodes and thus improving the safety performance of a battery cell. Moreover, the amount of the binder in the safety coating is optimized to promote the electrolyte absorption of the safety coating, which can improve the rate capability, the low- temperature discharge performance and the cycle performance of a battery cell. Ultimately, in the present invention, by limiting the particle size of the inorganic filler and selecting the binder, the rate capability, low-temperature discharge performance and cycle performance of a battery cell can be improved while the safety performance of the battery cell is enhanced.
