Not all new energy batteries are lithium batteries.
Lithium batteries are widely used in the field of new energy vehicles, but not all new energy batteries are lithium batteries. Currently, the power batteries used in new energy vehicles mainly include lithium iron phosphate batteries and ternary lithium batteries. Other types of batteries, such as lead-acid batteries and nickel-metal hydride batteries, are also used in some specific fields, but they are relatively poor in performance and environmental protection, their scope of application use is therefore relatively limited. Generally speaking, lithium batteries are widely used in the field of new energy vehicles, but not all of them are lithium batteries.
In the long term, the new energy sector still has prospects, and the current power battery market still has huge room for growth. Recently, amid a stable stock market, stocks of lithium battery separators and electrolyte-related concepts fell across the board, with Xingyuan Materials falling the most by more than 16%. electric companies Automaker NIO announced at the press conference that its new car will use solid-state battery technology. The NIO ET7 equipped with this battery has achieved a breakthrough of 1,000 kilometers, which can be said to be the most durable model in the world. the field of domestic new energy vehicles. The solid-state battery technology it uses is also considered a very radical step. You should know that most manufacturers still use batteriesliquids, and most people think there are problems with the charging efficiency of. solid-state batteries.
The difference between solid-state batteries and commercial batteries is that solid-state batteries use solid electrolytes to solve the separation problem of liquid batteries. Therefore, after the Weilai press conference, many battery separation material companies appeared. The reason for this decline is that solid-state batteries have been considered to have many problems in the past, such as poor fast-charging efficiency, resulting in slow charging, and the manufacturing process of solid-state batteries -conductors is relatively complex. Institutions have always believed that true mass production of solid-state batteries would take at least five to ten years. Earlier, CATL had also stated that the sThe company is said to launch its first mass-produced solid-state battery as early as 2030. Toyota, which is considered to be making the fastest progress in the field of solid-state batteries, also said that it will take longer to complete the production of solid-state batteries.
This time, Weilai suddenly launched this new car equipped with solid-state batteries without any noise, although its president Li Bin said that the new car would not be mass-produced before the first quarter of 2017. next year, and regarding solid-state battery information, Li Bin did not make any further announcements. He didn't even mention solid-state battery suppliers. He simply emphasized that it would certainly be the most advanced and closest to mass technology. production. Some professionals have pointed out that in fact, the solid battery advertised byr NIO this time is semi-solid and semi-liquid. On its promotional page it also states that it is a solid-liquid battery. It is estimated that NIO has adopted. this approach to increase the volume of solid-state batteries as quickly as possible.
However, some media guessed that the manufacturer that supplies solid-state batteries to Weilai may be Huineng, because the two parties established cooperation as early as 2019, and according to HuinengThe company's plan is to achieve mass production of semi-solid-state batteries (solid-state hybrids) in 2021. This moment is also similar to the time when NIO launched the semi-solid-state batteries, so the media suspects this manufacturer which supplies batteries for NIO is likely to do so. It's Hui Neng.
