Haopeng Technology applies for patents related to tab slot coating, using single-factor experiments to screen key parameters and optimize the coating process.

April 3 news, information from the National Intellectual Property Administration shows that Shenzhen HOPU Technology Co., Ltd. has filed a patent titled “A method for optimizing a coating process for centrally positioned coating in an electrode ear slot position.” The publication number is CN121765949A, the application number is CN202511948112.4, the publication date is March 31, 2026, the filing date is December 22, 2025. The inventors are Ye Zihui, Gan Zutao, Liu Guanxin, and Liao Xingqun. The patent agency is Beijing Xinhao LianDe Patent Agency (General Partnership), and the patent agent is Mai Jianwei. Classification numbers include G06F30/20, G01B5/06, G01B5/00, G06F18/2113, G06F18/25, H01M4/139, H01M4/04, G06F119/14.

The patent abstract shows that this invention relates to the technical field of coating processes and discloses a method for optimizing a coating process for centrally positioned coating in an electrode ear slot position. The method includes: based on the control groups of each test slurry, respectively form the corresponding single-factor control test group; for each test slurry, respectively use the coating-process parameter combination of its corresponding single-factor control test group to conduct a test of centrally positioned coating in the electrode ear slot position; and based on the test data, screen out key parameters that affect slot cleanliness, as well as key parameters that affect the consistency of slot-edge thickness. This invention uses single-factor control tests to separately screen key parameters that affect slot cleanliness and those that affect slot-edge thickness consistency, giving the process optimization direction a scientific basis based on facts, enabling rapid and convenient determination of the optimal process window, and promoting the engineering application and development of centrally positioned coating in electrode ears.
