What batteries will new energy vehicles be equipped with in the coming years?

In recent years, driven by the rapid development of new energy vehicles, the development speed of power batteries has accelerated. On January 16, at the \"One Smart Future\" New Energy Industry Summit and 2018 Power Battery Development Guidance Seminar under the New Situation, Dr. Fang Kaizheng of the China Energy Center automobile technology and research introduced: In 2017, China\'s new energy The total supporting volume of automobile power batteries was 37.37 billion watt hours, a year-on-year increase of 33%.

From an analytical point of view, it is expected that in the next few years, new energy vehicles will be equipped with more ternary batteries, and the vehicle purchaseNew energy icles equipped with ternary batteries will become a common phenomenon.

Purely electric passenger cars account for a high proportion of miniaturization

Data released by theChina Automobile Manufacturers Association shows that in 2017, the production and sales of new energy vehicles in my country reached 794,000 and 777,000 respectively, a year-on-year increase of 53.8% and 53.3%.

Dr. Fang Kaizheng pointed out that thanks to the penetration of the private market and the popularity of shared cars, the production of pure electric passenger vehicles increased by 83% per year. compared to last year. -year, and the production of special vehicles increased by 163%. . According to the analysis of the production of purely electric passenger cars in 2017, in terms of qualities, purely electric passenger cars representstill feel the highest proportion of miniaturization, with A00 class models accounting for 37%, A0 class models accounting for 34%. %, and class A models representing 37%. Automotive models represent 19%. At the same time, among these three levels of pure electric vehicles, the application of ternary material batteries occupies an important position.

The proportion of ternary battery support volume increased to 40%

According to Liu Yanlong, general secretary of China Chemical and Physical Food Industry Association. It is pointed out that in 2017, the total support volume of new energy vehicle batteries exceeded 37 billion watt hours. In terms of vehicle model classification, passenger cars were equipped with about 13.9 billion watt hours, accounting for nearly 38%; passenger cars accounted for around 14.5 billion watthours, or nearly 38%. This proportion reaches almost 39% and special vehicles represent almost 23%.

At the same time, in terms of battery classification, lithium-ion batteries still occupy a dominant position. In 2017, support volume was approximately 36.9 billion watt hours, or more than 99% of total support volume. Among them, lithium iron phosphate accounts for more than 48%. Thanks to the strong demand in the passenger car market and special vehicle market, rechargeable batteries have developed rapidly. In 2017, the proportion of the volume supported increased to 43%, now becoming a new source of energy. Another major trend in automotive power battery assembly.

Safety and longevity are the fundamental principles of electric batteries

It is indisputable that the new energy subsidiesques will continue to decrease in 2018. In the new political situationIn the current situation, there is a higher demand for improving the energy storage of battery units, but experts believe that the high safety and long service life of the product should be given greater attention. Wang Zidong, director of the National Power Battery Testing Center of the 863 Major Special Project for Electric Vehicles, believes that safety, long life and low cost are problems that need to be solved in the future without subsidies . General Secretary Liu Yanlong also emphasized: \"Whether the product safety and system life can meet user needs should be highly evaluated.\" It is hoped that key enterprises can provide better and safer electric battery products to the market.

WhenThis summit, Tafel New Energy Technology, as the organizer, launched two new products: one is for the passenger car and special vehicle markets. The 135Ah ternary aluminum square shell battery has an energy density of up to 215Wh/kg and a cycle life of up to 3000 times. The second is the 115Ah lithium iron phosphate battery cell for the energy storage and special vehicle markets, with a cycle life of up to 10,000 times. The design of Tafel battery cells in terms of energy density and service life is at the leading level in the industry, attracting the attention of guests present at the meeting.
