With the key support of the state, China has made significant progress in research on key technologies, key materials and products of power lithium batteries. The lithium battery industry has entered a critical stage of industrialization, promotion and application. The industrialization process of power lithium battery has been in an international leading position. 1. The development status of the lithium battery industry From January to November 2017, the domestic production and sales of new energy vehicles were 639,000 and 609,000, respectively, an increase of 49.7% and 51.4% year-on-year, of which the production and sales of pure electric vehicles were 532,000 and 50. 10,000 vehicles, up 56.6% and 59.4% year-on-year; the production and sales of plug-in hybrid vehicles were 107,000 and 105,000, up 22.5% and 21.8% year-on-year. Monthly sales data of new energy vehicles from 2015 to 2017. It can be seen that in 2017, except for the impact of the subsidy decline policy in January, the sales volume was lower than the previous two years. The monthly sales volume in other months exceeded the previous year's level, and the gap was gradually By November, the monthly sales data exceeded 54,000 and 66,000 in 2016 and 2015, respectively. The recovery of the new energy vehicle market is basically in line with the expectations in mid-2017. It is predicted that the sales of new energy vehicles in 2017 will most likely exceed 75. The scale of the lithium battery industry continues to expand, largely dependent on the vigorous development of new energy vehicles. From the perspective of my country's new energy vehicle output in recent years, it has maintained a trend of rapid growth year by year. In 2017, it was 782,000 vehicles, a year-on-year increase of 51.26%. From January to March 2018, my country's new energy vehicle output was 15 million. The report hall believes that 2018 is a transition year in which the growth momentum of new energy vehicles has shifted from purchase restrictions and subsidy policies to market-driven growth. It is expected to maintain rapid growth throughout the year . With the rise and development of the above-mentioned industries, the output of lithium batteries has also experienced rapid growth in recent years. The output of lithium batteries in my country reached 7.842 billion in 2016, an increase of 40.04% year-on-year, and a compound growth in 2014-2016. The rate reached 21.76%. And in the next few years, with the development of downstream demand-side industries, especially the rapid development of the new energy automobile industry, the demand for lithium batteries will continue to maintain a relatively high growth rate in the future. 2. The main problem of lithium battery research and development is the consistency of manufacturing. Due to the gap in the manufacturing process and equipment of lithium batteries, the domestic production process of lithium batteries is uneven, and the manufacturing standards are not consistent. The lithium batteries used in electric vehicles are all connected in series or in parallel. If the consistency problem is not solved well, the produced lithium batteries cannot be applied to electric vehicles on a large scale. The second is the issue of intellectual property rights. At present, domestic breakthroughs have been made in the research of lithium iron phosphate batteries. However, because the United States has patents in this area, although my country can independently research and develop in some aspects, it is still unclear how to deal with the issue of intellectual property rights. The third is the selection of raw materials. Now it is impossible to import all the raw materials used in the production of lithium batteries, mainly from domestic sources, but domestic raw materials must pass international certification before the lithium batteries produced can be internationally recognized, so there are still some problems in the raw material certification process. 3. Analysis of the development prospects of lithium batteries Trend 1: The scale of the industry is growing steadily, and China’s advantages are expected to expand. Analysis of the development prospects of power lithium batteries. In 2017, the growth rate of the main application markets for lithium-ion batteries slowed down, and the global lithium-ion battery industry scale exceeded 3,000 throughout the year. Billion yuan, the growth rate dropped by 4 percentage points compared with 2016. With the continued promotion of new energy vehicle promotion policies, China's electric vehicle production reached 650,000 in 2017, and its share in the global electric vehicle market will further increase. Trend 2: Power batteries lead the growth, and the market share will exceed 60%. Under the strong promotion of national financial subsidies, my country's new energy vehicle market is expected to expand to 650,000 in 2017, a year-on-year increase of 25%. The market for lithium-ion battery electric bicycles It is expected to reach 5 million vehicles. In addition to power tools and other fields, the power-type lithium-ion battery market is expected to reach 30GWh in 2017, a year-on-year increase of about 30%. On the whole, my country's power batteries will lead the growth of my country's lithium-ion battery market in 2017, and its share is expected to exceed 60%. Trend 3: The application of new technologies is accelerated, and disruptive products can be expected to analyze the development prospects of power lithium batteries. As the application of lithium-ion batteries in various fields is becoming more and more extensive, especially in the fields of electric vehicles, new energy, military, etc., countries and Major companies have increased their Ru0026D support. At the same time, the preparation technology of advanced materials such as graphene and nanomaterials has been continuously improved, and the integration with the research and development of lithium-ion batteries has been accelerated. The innovation of the lithium-ion battery industry has accelerated, and various products have come out and put on the market, which is full of gimmicks. In the future, with the continuous advancement of various new technologies, new materials including silicon-carbon composites, solid electrolytes, etc. are expected to be widely used in lithium batteries, and new ones may appear in specific application areas such as wearable devices and special environments. Disruptive lithium-ion battery products. With the gradual rise of the new energy vehicle market, power lithium batteries have become a strong growth point in the battery industry, and the trend of product demand has become a trend. Therefore, in the development and application of lithium batteries, the required cathode material has the characteristics of high potential, high specific capacity, and high density, which can maintain a longer service life and better use density.
