New energy electric vehicles under the popularity lithium batteries enter the new process.home energy storage lithium battery manufacturer

　　The development of new energy vehicles depends on the energy density of the battery. Based on the consideration of battery life, the new energy vehicle industry urgently needs high -energy density batteries to be put into use. Therefore, the world's development plans are about the development plan of power batteries, and many companies are "big movement." The British Oxis Energy Corporation recently announced that they have developed a lithium sulfur battery of 425 WH/KG. At present, HAPS high -altitude satellites are in use and planned to achieve the energy density of 500 WH/KG at the end of 2019.

　　Oxis plans to increase this value to 400 WH/KG by the end of 2019. The battery of this technology is mainly applied to large unmanned aircraft. There are also some problems on pure trams, such as life, power, charging time, etc. However, Oxis has now got Lisfab's funding. The goal of this project is to improve the battery life of the battery. If it can make breakthrough progress, its energy density will be greatly improved.

　　In addition, Japan Toyota has recently made significant progress in the battery technology of traditional semi -liquid electrolyte lithium -ion batteries using solid electrolyte instead of traditional semi -liquid electrolyte lithium battery. Due to the use of solid electrolytes, the improved battery volume is smaller and lighter than traditional lithium ion batteries, and it can also greatly increase the capacity of the battery, which makes the battery life of electric vehicles longer. Toyota said that the company has made significant progress in the manufacturing of this technology, and it is expected to apply the technology to electric vehicles as soon as 2020.

　　BMW also announced a new cooperation with SolidPower. The company will jointly develop solid battery technology for electric vehicles and develop a battery made of inorganic materials. Its energy density is higher than lithium ion batteries, which means Under the same size and volume, its energy is larger and longer. Compared with conventional liquid -based batteries, this technology has superiority in terms of safety, life and use environment, but there is still a long way to transform it into commercial applications.

　　Take the EV200 of BAIC New Energy, as an example, its battery cell is 400 WH/KG. According to a insider of the company, under the premise of maintaining the current battery capacity and the consumption of 100 kilometers per hour, one charging can not only reach 620 kilometers. At the same time, the cost has been reduced, the service life of the battery is extended, and the huge gap between the current electric vehicles and conventional fuel vehicles is effectively solved.

　　At present, leading companies in the domestic battery industry have been involved one after another, such as Ningde Times, BYD, Bick Battery, Waterma, Zhongtian Technology, etc. have begun research on solid -state lithium batteries. Among them, Ningde Times studied in the aspects of polymer materials and sulfide -based solid batteries. At present, preliminary results have been achieved. Zhongtian Company has signed a cooperation agreement with Qingdao Energy Research Institute to prepare for cooperation to develop high -performance full -solid lithium lithium. Battery.
