Two power battery industry giants launched a patent infringement lawsuit involving battery explosion-proof technology.

According to the CRE Daily17According to the report, Ningde Times New Energy Technology Co., Ltd. (hereinafter referred to as "Ningde Times") sued Jiangsu Tafel New Energy Technology Co., Ltd. (hereinafter referred to as "Tafel") for patent infringement, and the Fujian Higher People's Court has Formally accepted. Ningde era related staff revealed to the public, the subject of the case is.1.2The patent involved is a patented technology related to battery explosion protection, which plays a key role in the safety of battery production and use.

Ningde era in2011Founded in, is a focus on new energy power battery system, energy storage system research and development, production and sales and provide new energy application solutions. It is the largest power battery manufacturer in China, with installed capacity of up242.53MWh, the market share is43.8%. Table in2017Year7The main business is the research and development, production and sales of lithium-ion power batteries and energy storage batteries. This year1Month, Table45.39MWhThe installed capacity ranks eighth in the country. Tafel's two important shareholders are two investment companies with the background of Jiangning District SASAC in Nanjing and Fujian SASAC. Although it has not been established for a long time, Tafel's development speed is very eye-catching.

Judging from the research and development trends announced by Ningde Times, Ningde Times has designed explosion-proof plates to avoid pressure deformation or even explosion of lithium batteries in view of the emission of large amounts of gas during charging and discharging of lithium batteries. Although the explosion-proof plate can ensure the safety of users to the greatest extent, if the air pressure is lower than the design value, the explosion-proof plate will explode in advance, which will shorten the service life of the battery. In order to solve this technical problem, Ningde era invented an explosion-proof technology to ensure the safety of battery use and prolong the service life of the battery, and applied for relevant patents.

Through patent search, Tafel found that since.2017A total of applications have been applied since346patents, including221A utility model patent and.125patents, involving battery structure and explosion-proof technology.59Parts; ningde era since2010A total of applications have been applied since3036Patents3377items, which include1919utility model patents,1103invention patents and24Design patent, authorized invention patent.266In the Ningde era, there are as many patents on battery explosion-proof technology.109It can be seen that both companies have invested a lot of research and development work in optimizing the safety performance of batteries. The development time of Ningde era is earlier and more patents are applied for. If Ningde era has mastered the core patents of battery safety performance, it will inevitably form certain advantages. In this patent infringement lawsuit, if the infringement of Tafel, a rising star, is found to be established, it will bring huge economic and market losses to the development of Tafel. "We hope that the other party will stop manufacturing, selling and promising to sell battery products that infringe the patent rights of Ningde era, and compensate for the corresponding losses," Ningde Times said in an interview with blue whale financial reporters." What is the progress of the later stage of the case, whether Tafel will file a patent invalidation request for the patent involved, Ningde Times, as a listed company, should further disclose to the public.
