Power lithium batteries should start with electric bicycles

Power lithium batteries should start with electric bicycles Lin Daoyong, general manager of the system division of Shandong Runfeng New Energy Technology Co., Ltd., said in an interview that the state should use subsidies to develop lithium batteries for electric bicycles. It is reported that thanks to the rapid development of new energy vehicles, the power lithium battery market will rise rapidly in the future. From 2010 to 2018, the global power lithium battery market is expected to increase at a compound growth rate of 54.2% per year, and will reach US$16 billion by 2018. Although the market is attractive, the lithium batteries used in electric vehicles are very different from low-power lithium batteries. Low-power lithium batteries have more and more stringent requirements for power density, consistency and safety, and are far less complex than lithium batteries used in mobile phones, notebook computers and electric bicycles. In an interview with the author, Lin Daoyong, general manager of Shandong Runrun System Division of Peak Group New Energy Technology Co., Ltd., said that according to the current technical level of lithium batteries used in electric vehicles, there are still certain difficulties, because the battery is in the choice of materials and equipment. It is consistent with the management requirements of the battery company. Moreover, its demand for investment is huge, and tens of millions of yuan is nothing at all. Our company has invested hundreds of millions of yuan, and it still finds it difficult. To ensure the scale of processing, but also to ensure the advancement and consistency of the equipment, less money can only be a pie in the sky. Lin said. Cao Jianhua, the development director of Shenzhen Bangkai Electronics Co., Ltd., said that the problem of lithium batteries for electric vehicles is not very big, and the important bottleneck affecting its application is still supporting problems. He said that the first thing is the cost. A bus uses lithium batteries about 500,000 to 600,000 yuan, compared to an ordinary fuel vehicle, which costs 500,000 to 600,000 yuan. Secondly, the use environment is not very good. At present, the construction of charging stations at home and abroad has not yet formed a satisfactory network. Although the state has subsidies to support the development of electric vehicles, consumers are afraid to buy them because even if they buy a car, they cannot find a satisfactory charging system. Third, there is a lack of certification for electric vehicles, so few electric vehicles are now on the road and licensed, and customers do not have many models to choose from. Fourth, the standard system for electric vehicles has not been fully established, and there are still problems with the certification and after-sales service of the Transportation Administration. It is difficult to realize the industrialization of electric vehicles, because the technical bottleneck of lithium batteries that drive electric vehicles has not been broken. Therefore, I think the state should use these subsidies to develop lithium batteries for electric bicycles. The leverage effect of electric vehicles is very poor, Lin said. This is basically a full subsidy. For example, for an electric car battery of 50,000 yuan, the state will have to subsidize 50,000 yuan. Electric bicycles do not need to be subsidized 100%, but only 30%. In other words, the state can only subsidize 30% of lithium battery bicycles. Then the successful and relevant experience accumulated in the field of electric bicycles will be gradually extended to the field of electric vehicles, reaching the surface point, and finally reaching the goal of large-scale application of power lithium batteries in the field of electric vehicles. Power lithium-ion battery is the core component of electric vehicles, which determines the development route and operation mode of electric vehicles. The electric vehicle industry should follow the power of the battery. Yang, an academician of the Chinese Academy of Engineering, believes that the country should adopt the first strategy of automobiles and batteries, establish major projects for the development of power lithium batteries, improve power lithium ion battery processing skills, improve the industrial chain, complete barriers, electrolyte and battery processing equipment, and conquer batteries The module group skills put forward the safety and consistency of the battery, so that the battery can reach 1500 times; carry out original research, comprehensively improve the research capacity of power lithium battery, and have independent knowledge after supplying pure electric vehicle power lithium ion battery 5-10 years The core skills of property rights.
