Hey, tech fans and car enthusiasts, there's big news to share with you! BYD, the big guy who has been at the forefront of the field of new energy vehicles, has recently made a new move - they have applied for a patent for an all-solid-state battery!
This has to start with the State Intellectual Property Office, which shows that BYD filed a patent application in August 2024 called "all-solid-state batteries, battery packs and electrical devices". Doesn't that sound professional? Don't worry, I'll give you a brief explanation.
All-solid-state batteries, as the name suggests, means that the electrolyte in the battery is solid, which is not the same as the liquid electrolyte batteries we commonly use now. As for BYD's patent, their design is quite ingenious, the battery is staggered and stacked negative and positive electrode sheets, with a solid electrolyte layer sandwiched in between. Moreover, the outermost layer of the battery is also specially designed with a ceramic layer, so that the battery can be more uniform when it is under pressure and is not easy to be damaged, so that the first effect and cycle performance of the battery are on a higher level.
The significance of this patent is very great. You must know that solid-state batteries have always been a research hotspot in the new energy vehicle industry, because it can bring higher energy density, longer mileage, and a safer use experience. BYD's move is undoubtedly laying out the new energy vehicle market for the future, allowing us to see their determination and strength to continue to innovate.
However, there is still a way to go from patent application to practical application, and BYD's big step this time is enough to make us look forward to the future of new energy vehicles. Maybe one day, we will be able to drive a new BYD car equipped with an all-solid-state battery and enjoy a more convenient, safe and environmentally friendly travel experience!
BYD's application for an all-solid-state battery patent this time is definitely a big news worth paying attention to.
