Development of Lithium Ion Battery

　　China is a large producer of lithium batteries. According to the White Paper on the Development of Lithium Ion Battery Industry 2019, as the world's largest producer and application market, China's position in the global lithium battery industry has been rising, especially thanks to the continuous development of new energy vehicles. The scale of China's lithium battery industry has been growing in recent years. The data shows that China's cumulative production of lithium batteries reached 13.99 billion in 2018, The year-on-year growth rate was 25.9 percentage points, and the industrial scale reached 172.7 billion yuan, a year-on-year growth rate of 9 percentage points. In 2018, China's lithium battery market output exceeded half of the global output, and the market value of industry companies exceeded 1 trillion yuan. The global demand for lithium batteries also showed an upward trend, bringing new business opportunities for related fields;

　　At present, with the advent of the development trend of new energy vehicles, lithium batteries can play a role, thanks to the strong support of the national government and the CE for the new energy vehicle industry. Since this year, China's power type lithium batteries have developed rapidly. The high energy density and high stability lithium batteries of vehicle specifications have expanded the prospects of the electric vehicle industry, which has been preliminarily recognized by the government and the market. Since this year, with the adjustment of the subsidy policy and CE for new energy vehicles, The cost pressure of lithium battery will be amplified, and some low-end products will be eliminated, which will make the market competition more intense. This will force relevant enterprises to win advantages in the competition with higher product cost performance ratio and faster market reaction ability;

　　At the same time, it should be noted that the development and application of lithium batteries still face many challenges. For example, in the actual use process of lithium battery new energy vehicles, there are problems such as low energy density, long charging time, low low-temperature performance and short service life. The core technology has not achieved significant breakthroughs, and there are still some hidden dangers in safety. For these problems, scientific research needs to be further deepened, It is also inseparable from the further exploration of other clean energy;
