In many families with electric vehicles in the north, they will worry about battery life in winter, and they must pay attention to the safety of electric vehicle battery charging. As a means of transportation, electric vehicles have brought us a lot of convenience and safety hazards. During the '13th Five-Year Plan' period, the production and sales of new energy vehicles in my country have grown rapidly, ranking first for five consecutive years. Electric vehicles and batteries for new energy vehicles have become a topic of concern to many people. Recently, the newly developed new nano-silicon lithium battery developed by Yinlong New Energy Energy Storage System Research Institute and China's lithium battery Ru0026D team in Zhuhai, Guangdong, has been successfully developed. A new type of nano-silicon battery comes out: the capacity is 5 times that of the traditional battery. Chen Liquan, academician of the Chinese Academy of Engineering, is 80 years old this year and is the founder of my country's lithium battery industry. In the 1980s, Chen Liquan led the team to pioneer research on solid electrolytes and lithium secondary batteries. After years of hard work, a lithium-ion battery was finally developed in 1996. This technology also solves the scientific, technological and engineering problems of domestic large-scale production of lithium-ion batteries and realizes the industrialization of domestic lithium-ion batteries. Under the leadership of Li Hong, a proud student of Academician Chen Liquan in Liyang, Jiangsu, his Ru0026D team has finally overcome a new type of nano-silicon material after more than 20 years of technical research, and mass-produced this new material in 2017. Li Hong introduced: 'The new battery raw material we independently developed as the nano-silicon anode material. The button battery made from it has 5 times the capacity of the traditional graphite lithium battery.' In this factory in Liyang, a drone with a solid-state lithium battery developed by Professor Li Hong has a 20% increase in range compared to a drone of the same specification. The battery uses the solid-state cathode material they developed: 'In 2018, the design and development of a 300Wh/Kg solid-state power battery system has been completed here. After the vehicle is equipped, the vehicle's cruising range can be doubled. In 2019, the Chinese Academy of Sciences established a solid-state battery trial production line in Liyang. This year Since May, some products have been used in consumer electronics products.' Technology changes lives: Electric China is building new materials. The successful research and development of new materials is not only the hard work of scientists, but also the construction of many companies. Many companies are constantly exploring new technologies and new materials for new energy batteries. The new energy technology is used in the buses of this new energy company in Zhuhai, Guangdong. The engineer of Yinlong New Energy Energy Storage System Research Institute said: When the bus enters the charging area, the remaining 33% of the electricity will rise to more than 60% after 3 minutes of charging. The battery is fully charged. When invited, Chen Liquan also mentioned that the success of the research and development of the new nano-silicon lithium battery has also broken the problem of energy consumption loss of charging cars in low temperature environments. After many tests, the new nano-silicon lithium battery can still be used normally in an environment of minus 50 degrees: 'For the future development of power batteries and energy storage batteries, the safety and cost of the battery still need to be considered. Because of these two The reason is still the core of technological breakthroughs such as power batteries and energy storage batteries.' Through the comprehensive development of research on different technical routes, relying on the diligence and wisdom of the Chinese people, we will surely overcome the 'pain points' of the development of new energy vehicles and lead the new development of new energy vehicles. The future of 'Electric China' can be expected.
