The number one solid-state battery manufacturer in China is CATL.
Founded in 2011, CATL New Energy Technology Co., Ltd. is one of the earliest internationally competitive power battery manufacturers in China, focusing on new energy vehicle battery systems and systematic energy storage. R&D, production and sales are committed to providing first-class solutions for global new energy applications. The core technologies include the whole industrial chain, R&D of materials, cells, battery systems, battery recycling and secondary use in the field of energy storage and energy batteries. . Manufacturing capacity.
In 2017, the company's power lithium battery shipments were well ahead of the world, reaching 11.84 GWh, and she establishedcooperative relationships with many large groups. domestic car manufacturers. , and successfully occupied a place in the global market and became the first domestic lithium-ion battery manufacturer to enter the supply chain of major international automobile companies.
Solid-state battery
Solid-state battery is a type of battery technology different from lithium-ion batteries and lithium-ion batteries commonly used polymer ion. today, solid-state batteries A battery is a battery that uses solid electrodes and solid electrolytes.
Because the scientific community believes that lithium-ion batteries have reached their limits, solid-state batteries have been considered in recent years as batteries that can inherit the status of lithium-ion batteries. The technology uses glass compounds madeuses lithium and sodium as conductive materials, replacing the electrolyte of previous lithium batteries and significantly improving the energy density of lithium batteries.
Bitauto News Recently, news broke that the new solid-state lithium battery developed by BYD was produced in Chongqing and was on about to be tested in vehicles. The project is led by Academician Ouyang Ming Gao took the lead, and three other academician consultants participated in the research and development of BYD's all-solid-state lithium battery. This is a national standard key project. What are the differences between this and liquid. batteries?
First, the electrolyte inside the liquid lithium battery is replaced with a solid electrolyte. The specific energy density can be increased from the limit of 300 Wh/kg of battery toliquid lithium at 700 Wh/. kg in 10 minutes. All of them are fully charged, because there is no liquid electrolyte, which almost completely eliminates spontaneous combustion of the battery, which can be considered a breakthrough technological innovation.
In addition to BYD's use of its own models, BYD's first batch of all-solid-state batteries will also be supplied to other companies, including Mercedes-Benz , BMW, Audi and Hongqi could be prioritized. BYD offers three options for future battery technology: blade, hexagonal or 2025 all-solid. All-solid-state batteries are divided into two technical paths. The first type of solid-state oxide battery has been manufactured by BYD and is ready for installation. BYD's second type of solid-state battery is a sulfide technology route. Trial production has been completed and reached the testing standards. Ready to charge.
HeIt is reported that BYD has invested in solid-state lithium battery research as early as 2016 and is currently working on The number of relevant national patents is far ahead, ranking first. Its two technical avenues, solid-state lithium oxide batteries and solid-state lithium sulfide batteries, have completed production and are ready for vehicle testing. The next step is mass production and marketing. application. . CATL, also a battery giant, is also intensively developing solid-state lithium batteries and is expected to achieve commercial mass production of solid-state lithium batteries in 2030.
