South Korea's energy and chemical enterprise SK Innovation (SK? Innovation) announced a new type of battery, which will make the electric car travel 800 kilometers after two quick charges in 10 minutes. In addition, the cathode with high nickel content is expected to enter mass production soon.
This new type of high-speed rechargeable battery will be developed in the first half of 20021year at the latest, and SK Innovation said that they will "play an important role in the popularization of electric vehicles". This statement was made at the inter-battery meeting hosted by the Korean government. The company did not give more information about this battery, but said that the design of the new battery can meet more than 65,438+0,000 charging cycles and will have higher energy density.
As we all know, SK Innovation is the battery supplier of Volkswagen ID.4 produced in the United States. The production of American Volkswagen ID.4 is scheduled to start in Chattanoou processing plant in 2022, which means that at least in time, this type of battery will be possible to be used in this Volkswagen electric SUV.
American Volkswagen ID.4 is expected to use this new battery?
SK Innovation has decided to focus its research and development on "long-life batteries for long-distance travel". Home SUVs like ID.4 will use this solution to solve the problem of increasing storage capacity in smaller battery packs. Although the space of such a small car is very small, it can provide a longer cruising range, and the charging ability is fast and the charging time is short, which is more suitable for long-distance travel.
In order to realize the "long-cherished wish" of high-speed charging in the electric vehicle industry, the company developed this battery, which can travel 800 kilometers after charging twice 10 minute. SK？ Innovation did not provide more details in the statement. Assuming that the battery is fully charged at the beginning of the trip and the batteries in both charging stations are not fully charged, it means that the charged battery can travel about 10 to 200 kilometers after charging for10 minutes.
Regarding another long-distance battery, the information given by SK Innovation is more specific. It is said that in a test drive, the cruising range can reach 1000 km under the best driving conditions. The battery cell adopts NCM9 as the positive electrode, and the nickel content reaches 90%, which is higher than that of NCM622 and NCM8 1 1. Relatively speaking, the proportion of cobalt and manganese will be reduced to 5% respectively. The new cathode will obviously enter mass production soon.
The statement did not explicitly mention SK Innovation and LG Chemical (LG? Chem) The latest development of legal disputes, both Korean companies accuse each other of patent infringement. Nevertheless, the company seems to be tempted to dig at its Korean competitors. According to the press release, SK Innovation has provided batteries for electric vehicles and plug-in hybrid vehicles for 65,438+00 years, "without a battery fire".
Recently, both Hyundai Kona electric car and Chevrolet Bolt electric car have encountered the problem of car fire, and the batteries of both products are from LG Chemical Company. It should be pointed out that compared with Panasonic, LG Chemical or Contemporary Ampere Technology Co., Ltd., SK Innovation has a big gap in the installed capacity of power batteries. Kia's e-Niro and Hyundai Kona*** enjoy most of the driving technology, but its battery comes from SK innovation, so far there has been no such battery problem.
