Generally, the storage performance of the battery will decrease as the number of charge and discharge times increases, and the user will face the problem of insufficient battery life. On March 22, 2017, Tesla, who led the electric vehicle field, announced that they have achieved breakthrough results in the field of power batteries. Tesla's chief battery scientist Kurt Kelty and technology research partner Jeff Dahn of Dalhousie University in Canada gave a speech at the International Battery Symposium and Exhibition, saying that the battery pack capacity was only 5% after the Tesla Model 3 was driven 480,000 kilometers. Increasing the chemical composition of the NMC ternary lithium battery can limit the harmful gases generated during high-voltage operation of the battery, and the improved battery cell can still have excellent performance after more than 1200 cycles. Based on 20,000 km/year, a regular car can drive a Tesla car for 80 years. The new technology has been commercialized and used in Tesla products and is expected to be the Model 3 sedan, which is scheduled to be launched in July this year. This is indeed an exciting news for anyone in the battery industry. Compared with electric vehicles, fuel vehicles have a future that is self-evident. The battery problem of long battery life and energy attenuation is solved, and the market capacity of electric vehicles is only a matter of time. The production and application market of electric vehicles is one of the performances of the successful commercialization of the energy storage industry and rapid development. According to incomplete statistics, in 2015, the production and sales volume of low-speed electric vehicles in China was about 700,000 units, and in 2016, it reached 1.2 million units. From the perspective of the development route of electric vehicles and battery technology, low-speed electric vehicles will be the mainstream of the development of electric vehicles in China in the last decade, and an important supplement to the new energy automobile industry in the next decade. Technological innovations in the battery sector have also demonstrated possibilities for the energy storage industry. Last year, Huawei's Central Research Institute Watt Lab announced at the 57th Japan Battery Conference that it has achieved major research breakthroughs in the field of lithium-ion batteries and introduced the industry's first high-temperature long-life graphene-based lithium-ion battery. The experimental results show that the new high temperature resistant technology based on graphene can increase the upper limit of lithium ion battery use temperature by 10 °C, and the service life is twice that of ordinary lithium ion batteries. According to the data released by the National Bureau of Statistics, in January and February 2017, the cumulative output of lithium-ion batteries in China was 1,14,485,500, with an average monthly output of 572.42 million. Through repeated technological innovations, the development of batteries will help realize the safe and fast charging function of electric vehicles, and rapidly promote the marketization of electric vehicles. The true combination of the new energy automobile industry and the energy storage industry is also within reach. Cao Cheng, the person in charge of the 2nd Asia-Pacific Battery Show held in Guangzhou Canton Fair Complex on August 16-18, 2017, is China's superpower for new energy promotion and application. In recent years, the state has introduced relevant support. Policies can shed light on the government's determination to develop new energy industries such as electric vehicles and energy storage. The Asia-Pacific Battery Show is in line with the government's plan for the development of the new energy industry in the future with its international high-end positioning. It has received key government support and fully subsidized enterprises to exhibit. Exhibitor data may reflect the development of the current battery industry. It is reported that compared with last year, the companies active in the exhibition this year have increased by 500% year-on-year. The power giants such as Lishen Battery, Waterma Battery, Haisida, Shuangdeng Group, Keihin Electronics and other BMS companies , Hongbao Technology, Jinming Technology, Han's Laser and other battery equipment companies, Kaipu Rui Te, Haili shares and other battery materials companies have joined. By the time of launch, only the battery and BMS segment brand companies will have an exhibition area of ​​15,000 square meters. Buyers are expected to have 35,000 visitors from more than 40 countries and regions around the world, and the proportion of foreign buyers will reach 15%. In the same period, the “2017 Asia Power Battery and Energy Storage Technology Summit†will focus on three core contents: “Power Battery Technology and Intelligent Manufacturingâ€, “Power Battery Application and BMS Battery Management Systemâ€, “Energy Storage System, Technology and Engineering Applicationâ€. Discussion. The "high-end product display + technology forum" dual-engine mode can play a very good role in promoting the healthy and orderly development of the domestic battery industry. I believe that the battery industry enterprises with real technical strength will not miss this kind of international battery. The opportunity to announce research results to the world at the conference. In the past five years, the annual compound growth rate of the global energy storage industry has reached 193%. It is expected that the capacity of China's energy storage market will reach 100 billion US dollars in the next 10 years. The energy storage cost has further declined, the peak-to-valley electricity price system has been perfected, the demand-side management and other compensation mechanisms have been established, and various value-added services on the user side of the power market have been developed, and the energy storage segment has been continuously developed and applied. The energy storage market will become the pioneer of energy storage in China. According to the starting point study (SPIR) forecast, the energy storage field has become the main choice for large enterprises in the process of facing the saturation of traditional business or implementing transformation and development. The market growth space will exceed 100 billion yuan in the next five years. Nandu Power, Shanshan, Guoxuan Hi-Tech, Xiongyi, and Mengshi Technology have stepped up their efforts in the field of energy storage. At present, energy storage has been included in China's “13th Five-Year Planâ€, and it is also the first time to officially enter the national development plan. At the same time, relevant policies such as the “13th Five-Year Plan†for the energy storage industry have begun to be prepared, and follow-up is expected to be introduced. At the same time, the National Development and Reform Commission and the National Energy Administration jointly issued the "Energy Technology Revolution Innovation Action Plan (2016-2030)" and the "Energy Technology Revolution Key Innovation Action Roadmap", requiring research on solar thermal energy efficient use of high-temperature heat storage technology, Large-capacity heat storage (cold) technology for distributed energy systems. Research on energy storage technologies for power grid peak shaving and efficiency, regional energy supply applications, renewable energy grid-connected, distributed and micro-grid, electric vehicle energy storage technologies, master key technologies of all aspects of energy storage technology, complete Demonstration verification, the overall technology has reached the international leading level, leading the development of international energy storage technology and industry. The development of China's energy storage market has entered a turning point in commercial development. At present, the high cost of energy storage and the technical cost of new energy fields are still paid by the government, completely switching to market pay, and the user's pay is the goal of the next stage. Looking at the current aggressive capitals and enterprises in the battery field, the overall situation of the secondary energy market with electricity as the carrier tends to be optimistic.
