Huizhou EVE Energy Co., Ltd. has recently secured a patent for a new lithium battery structure, enhancing the stability of battery performance. According to information from the National Intellectual Property Administration, the patent, titled “A Lithium Battery Structure,” has the authorization announcement number CN 222801929 U and was applied for on February 2024.
The patent summary indicates that the utility model reveals a lithium battery structure that consists of a shell and a cap. The cap features a structural plate and a top cover, which is positioned away from the shell on one side of the structural plate. The edge of the structural plate is bent up towards the side of the top cover, forming a second assembly groove, into which the top cover is embedded. The structural plate is installed at one end of the shell.
By embedding the top cover into the second assembly groove on the structural plate, the relative position of the top cover and the structural plate is fixed. This innovation reduces the range of fluctuation in contact resistance between the top cover and the structural plate, thereby enhancing battery performance stability and extending the lifespan of the lithium battery. Furthermore, the wall of the three sides of the second assembly groove contacts the top cover, in contrast to the existing technology where the top cover only contacts one side of the structural plate. This utility model increases the contact area between the top cover and the structural plate, lowers contact resistance, and improves battery performance.
According to data from Tianyancha, Huizhou EVE Energy Co., Ltd. was established in 2001 and is located in Huizhou City. The company primarily engages in wholesale activities and has a registered capital of approximately 2,045.721497 million RMB. Through big data analysis from Tianyancha, it is noted that Huizhou EVE has invested in 45 companies and participated in 190 bidding projects. The company has 286 trademark records and 3,531 patent records, along with 380 administrative licenses.
