Haopeng Technology obtains patents related to battery fabrication methods, detects hardness after hot pressing, and screens battery cells to improve battery production efficiency.

April 3 news, according to information from the National Intellectual Property Administration, Shenzhen Haopeng Technology Co., Ltd. has applied for a patent titled “Battery Preparation Method.” The authorized publication announcement number is CN119230968B, with the authorization announcement date being March 31, 2026. The application publication announcement number is CN119230968A, the application number is CN202411400318.9, the application publication date is March 31, 2026, the application date is October 8, 2024. The inventors are Wu Jingjing, Liu Canzheng, Yang Yongde, Ge Chongyong, and Liao Xingqun. The patent agent is Beijing Huixin Jinda Intellectual Property Agency Co., Ltd., and the patent agent is Huang Hongsheng. Classification numbers are H01M10/0587, H01M10/0525, and H01M10/04.

The patent abstract shows that this application involves a battery preparation method. The method includes: battery preparation method, including: obtaining a wound battery cell to be processed; subjecting the wound battery cell to thermal pressing and detecting whether the surface hardness of the wound battery cell after thermal pressing reaches a preset hardness range; packaging the wound battery cell whose surface hardness reaches the preset hardness range into a can as a target cell; and removing the wound battery cell whose surface hardness is outside the preset hardness range. The proposed solution can detect whether the surface hardness of the wound battery cell after thermal pressing is within the preset hardness range, partition and package the wound battery cells whose surface hardness is within the preset hardness range into cans, and remove the wound battery cells whose surface hardness does not reach the preset hardness range, thereby effectively reducing the entry of over-thermally-pressed wound battery cells into the packaging-inserted-into-a-can process, effectively improving battery production quality, and also effectively increasing the yield of packaging wound battery cells into cans, thus improving battery production efficiency.
