How can 3500mah 18650 battery break through the development bottleneck? Three major paths open up a new green charging ecosystem

Compared with fuel vehicles, pure electric vehicles have short cruising range and long charging time, which are factors that restrict their rapid development. However, from the 15th to the 13th Five-Year Plan, the power battery industry has gradually moved towards a path of rapid development. Ouyang Minggao, executive vice president of the China Electric Vehicle Hundred People's Association and academician of the Chinese Academy of Sciences, said that the specific energy of power battery systems is increasing year by year and the cost is decreasing. The battery industry is accelerating. Miao Wei, Minister of Industry and Information Technology of China, said that by the end of 2017, a total of 214,000 public charging piles had been built nationwide, an increase of 51% year-on-year, ranking first in the world in terms of ownership, and the installation rate of private charging piles for new users exceeded 80%. Against the backdrop of continued increases in fuel prices, continuous improvement of charging pile hardware equipment, and frequent implementation of preferential policies for new energy vehicles, more and more purchasing power is shifting to the new energy field, and the resulting new energy boom may begin to erupt this year. In the development of new energy vehicles, 3500mah 18650 battery are the heart of new energy vehicles, and charging and battery replacement are an unavoidable key link. However, the development of power battery technology in my country is not balanced, and the overall energy consumption of electric vehicles is relatively high, especially the depreciation rate of pure electric vehicles is currently mainly determined by battery life. As the first batch of new energy vehicles have entered the replacement period. The industry generally believes that the core of the development of new energy vehicles is the urgent need for breakthroughs in power battery technology. Otherwise, under the concern about batteries, there may be a situation where new energy vehicles have no next buyer to take over. At present, it is difficult for the power battery industry to form a polymerization effect in a short period of time. Although it seems to be overcapacity in terms of scale, in fact, there are not many high-quality and high-quality enterprises and products. At a time when the power battery industry is facing a reshuffle, exploring a cleaner, more efficient and economical technical path has become an urgent need for the development of the industry. On March 1, 2017, the Ministry of Industry and Information Technology, the National Development and Reform Commission, the Ministry of Science and Technology, and the Ministry of Finance issued the "Action Plan for Promoting the Development of the Automotive Power Battery Industry", which proposed the main goals of power battery development. By 2020, the specific energy of new lithium-ion power battery monomers will exceed 300 watt-hours/kilogram. There is still a lot of room for improvement in lithium-ion power battery technology. At present, more than 54% of the new energy vehicle market are pure electric passenger cars. In 2017, my country's power battery technology has made substantial progress, and the energy density of power battery systems has reached more than 150 watt-hours/kilogram, but the industrialization of my country's solid-state batteries has not yet arrived. At present, domestic and foreign technology research and development is basically at the same level, but the core of lithium-ion batteries is safety. In the next step, the industry needs to continue to focus on technological breakthroughs in lithium-ion batteries and the development of electric vehicle energy consumption and energy-saving technologies, fast charging and intelligent charging network technologies. From the perspective of the new energy system, with the introduction of power system reform policies, distributed energy trading policies, and the construction of photovoltaic power generation, electricity sales, and retired battery energy storage systems, the new green charging ecology of "light-storage-charging integration" for new energy vehicles has been prepared. The docking of 3500mah 18650 battery and photovoltaic technology may realize real clean travel. From the perspective of charging mode, at the same time, Ouyang Minggao believes that intelligent charging will trigger an energy revolution. Under the prospect of accelerated development of intelligence, after 2025, the promotion of a new generation of charging technology, large-scale infrastructure transformation, and the realization of new energy intelligence will be promoted. In addition to the intelligence of autonomous driving, the intelligence of new energy must also be realized to meet the rapid charging needs of passenger cars and bring about a revolution in the entire energy transportation system. With the deep integration of the new energy automobile industry with new technologies such as electrification, intelligence, and informatization, China's automobile industry will embark on a path from an automobile power to an automobile powerhouse.
