Analysis of the current situation and development prospects of the lithium battery industry. With the key support of the country, significant progress has been made in the research of key technologies, materials, and products for power lithium batteries in China. The lithium battery industry has entered a critical stage of industrial construction and promotion of application. The industrialization process of power lithium batteries has taken an international leading position.

1、 Current Development Status of Lithium Battery Industry

From January to November 2017, the production and sales of new energy vehicles in China reached 639000 and 609000, respectively, with year-on-year growth of 49.7% and 51.4%. Among them, the production and sales of pure electric vehicles reached 532000 and 500000, respectively, with year-on-year growth of 56.6% and 59.4%; The production and sales of plug-in hybrid vehicles reached 107000 and 105000 respectively, with year-on-year growth of 22.5% and 21.8%.

From 2015 to 2017, it can be seen from the monthly sales data of new energy vehicles that in 2017, except for January, which was affected by the subsidy and slope reduction policy and 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 gradually widened. By November, the monthly sales data exceeded 54000 and 66000 units in 2016 and 2015, respectively. The recovery trend of the new energy vehicle market is basically in line with the expectations for mid-2017, and it is predicted that the sales of new energy vehicles for the whole year of 2017 will likely exceed 75%

The scale of the lithium battery industry continues to expand, largely relying on the booming development of new energy vehicles. In recent years, the production of new energy vehicles in China has maintained a rapid growth trend year by year, with 782000 vehicles in 2017, a year-on-year increase of 51.26%. From January to March 2018, China's production of new energy vehicles was 150000 units. The report hall believes that 2018 is a transitional year for the growth of new energy vehicles from being driven by purchase restrictions and subsidies to being driven by the market. It is expected to maintain rapid growth throughout the year.

With the rise and development of the above-mentioned industries, the production of lithium batteries has also experienced rapid growth in recent years. China's lithium battery production reached 7.842 billion natural units in 2016, a year-on-year increase of 40.04%, and a compound growth rate of 21.76% from 2014 to 2016. In the coming years, with the development of downstream demand side industries, especially the rapid development of the new energy vehicle industry, the demand for lithium batteries will continue to maintain a high growth rate.

2、 The main problems in the research and development of lithium batteries

The first issue is the consistency of manufacturing. Due to differences in the manufacturing process and equipment of lithium batteries, the production process of domestic lithium batteries is uneven, and the manufacturing standards still cannot reach consistency. The lithium batteries used in electric vehicles are all connected in series or parallel. If the consistency problem is not solved well, the produced lithium batteries cannot be widely applied in electric vehicles.

Next is the issue of intellectual property rights. At present, breakthroughs have been made in the research of lithium iron phosphate batteries in China. However, due to the United States having patents in this area, although China can independently research and develop in some aspects, it is still unclear how to respond to intellectual property issues.

The third issue is the screening of raw materials. At present, it is not possible to import all the raw materials used for lithium battery production, mainly from China. However, domestic raw materials need to pass international certification in order to produce lithium batteries that can be internationally recognized. Therefore, there are still some problems in the raw material certification process.

3、 Analysis of the Development Prospects of Lithium Battery

Trend 1: The industrial scale is steadily growing, and China's advantages are expected to expand

Analysis of the development prospects of power lithium-ion batteries: In 2017, the growth rate of the main application market of lithium-ion batteries slowed down, and the global lithium-ion battery industry scale exceeded 300 billion yuan for the whole year, a decrease of 4 percentage points compared to 2016. With the continued promotion of new energy vehicle policies, China's electric vehicle production reached 650000 units in 2017, and its share in the global electric vehicle market will further increase.

Trend 2: Power batteries lead growth, with a market share exceeding 60%

Under the strong promotion of national financial subsidies, the new energy vehicle market in China is expected to expand to 650000 units in 2017, a year-on-year increase of 25%. The market for lithium-ion battery electric bicycles is expected to reach 5 million units, and with the addition of power tools and other fields, the market size of power type lithium-ion batteries is expected to reach 30 GWh in 2017, a year-on-year increase of about 30%. Overall, in 2017, China's power batteries will lead the growth of the lithium-ion battery market, with their proportion expected to exceed 60%.

Trend 3: Accelerated application of new technologies, disruptive products expected

Analysis of the development prospects of power lithium-ion batteries. With the increasingly widespread application of lithium-ion batteries in various fields, especially in electric vehicles, new energy, specialty and other fields, countries and major enterprises have increased their research and development support. At the same time, advanced material preparation technologies such as graphene and nanomaterials are constantly improving, and the integration with lithium-ion battery research and development is accelerating. The innovation speed of the lithium-ion battery industry is accelerating, and various products have been launched and launched in the market, full of gimmicks.

In the future, with the continuous progress of various new technologies, new materials including silicon carbon composite materials, solid electrolytes, etc. are expected to be widely used in lithium batteries. In specific application fields such as wearable devices and special environments, new disruptive lithium-ion battery products may emerge.

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 increasing product demand has become. Therefore, in the research and application of lithium batteries, the required positive electrode materials have characteristics such as high potential, high specific capacity, and high density, which can maintain a longer service life and better usage density.
