Ternary material or energy battery development focus

In the case of the limited theoretical energy density of lithium iron phosphate batteries, in order to improve the cruising range of vehicles, high energy density ternary material lithium-ion batteries are generally favored by the market.

As a result of haze and atmospheric pollution, it is imperative to promote air pollution control. The promotion of green travel and the development of new energy vehicles are one of the effective ways to achieve the goal of energy conservation and emission reduction. Therefore, national policies have greatly encouraged the development of new energy vehicles, and dozens of projects have been introduced since the beginning of the year. Central and local new energy vehicles related policies.

China's new energy vehicle market usher in an inflection point In 2014, the sales volume of China's new energy vehicles is expected to reach 70,000 vehicles, which is about to usher in a turning point.

In 2014, the favorable policies for China's new energy vehicles were frequent, and the development of new energy vehicles gradually rose to national strategies. Since 2013, China's new round of new energy automobile policies have frequently promoted the rapid development of the domestic new energy automobile market. This round of industrial policies shows that the national and local levels complement each other, and the infrastructure construction promotes the country in real terms. The characteristics of multi-sector linkages among ministries and commissions.

On this basis, domestic new energy vehicles are booming. From January to September 2014, the cumulative output of new energy vehicles reached 41331, which was a four-fold increase from the same period of last year. The domestic new energy automobile industry policy is mainly based on downstream application market development, supplemented by tax incentives, and is intended to drive the new energy automotive industry to break through the expansion of downstream industry scale.

The new energy automotive industry policy also presents two major characteristics: First, the development strategy of new energy vehicles has become an important part of the energy conservation and environmental protection strategy. Second, the local policies and measures for new energy vehicles have been further refined, and the industry has entered a substantive start-up phase.

New energy vehicles have become an important part of the energy conservation and environmental protection strategy. In July 2013, the State Council executive meeting proposed that energy-saving and environmental protection industries have become the pillar industries of China's industrial development, and pointed out that government official vehicles and buses should take the lead in promoting the use of new energy vehicles and improve their supporting facilities.

In September of the same year, the State Council issued the "Action Plan for Prevention and Control of Atmospheric Pollution," and the Beijing-Tianjin-Hebei Region, the Yangtze River Delta Region, and the Pearl River Delta Region have become key areas for the control of air pollution. New energy vehicles as an important measure to strengthen prevention and control of pollution from pollution sources have been valued by local governments. . In the same period, new energy vehicle promotion plans put forward by local governments such as Beijing, Shanghai and Shenzhen were formulated based on the objectives of the Air Pollution Prevention Action Plan.

With the intensive launch of the new-energy automobile industry policy at the national level in 2013, local governments have successively launched new energy vehicle promotion plans and corresponding policy measures. Due to the higher promotion threshold set for the promotion of new energy vehicles in this round of the country, local governments with industrial technology and economic foundation are objectively encouraged to participate.

From the participation of more than 40 cities and regions, Shenzhen, Shanghai and Beijing have become the leading areas for the advancement of large-scale cities for new energy vehicles. The promotion of this round has also introduced many local policies and measures at the local level. It has formulated detailed rules and preferential policies in the fields of the construction of private charging stations and the operation of charging stations for enterprises. With the business model innovation as an opportunity, the development of new energy vehicles has shown a booming trend.

With strong policy support, domestic new energy vehicles are developing rapidly. The annual sales of new energy vehicles this year must exceed 50,000 vehicles. From the perspective of foreign experience, the annual sales of new energy vehicles exceed 50,000 vehicles, and the market will change from quantitative to qualitative. New energy vehicles are expected to move toward commercial operation. Taking the development of the new energy vehicle market in the United States as an example, the sales volume of new energy vehicles in the United States exceeded 50,000 in 2012, and the growth rate in 2013 reached 80%.

Since 2014, the sales of electric vehicles in the United States have continued to prosper. In the first half of the year, new energy vehicles have sold 55,000 vehicles, a year-on-year increase of 44.5%. It is expected that sales of new energy vehicles in the United States will reach 165,000 in 2014.

From the current situation of promotion and application throughout China, sales of new energy vehicles in China are expected to reach 70,000 units in 2014, and we are about to usher in a turning point.

The domestic power lithium battery market pattern gradually becomes the domestic demand for lithium battery power of this year will reach 1.4GWh, with an output value of about 4 billion yuan.

The sales of new energy vehicles have boosted the domestic demand for lithium-ion batteries. The market expects that the sales of new-energy vehicles will reach 70,000 units this year. According to the average of 20kWh, the demand for domestic lithium-ion batteries will reach 1.4GWh this year. The scale is about 4 billion yuan.

At present, the major Chinese lithium battery manufacturers include: BYD Co., Ltd., which will have a capacity of about 1.6 GWh at the beginning of 2014. By the end of the year, the production capacity is expected to increase by 3GWh. The product is a lithium iron phosphate battery. In the first half of 2014, the company’s new energy automotive business realized revenue. About 2.748 billion yuan, an increase of 1216.67%, accounting for 10.29% of the group's total revenue, pulling the demand for power lithium battery is about 0.37GWh.

Tianjin Lishen Battery Co., Ltd. has an annual production capacity of approximately 0.7 GWh of power cells and is currently seeking for an expansion of its production capacity. The company's main customers include Conti, Zhongtai, and JAC. The company's total operating revenue in 2013 was 3.15 billion yuan. In the first half of 2014, the company Power lithium battery shipments were approximately 79.7 MWh.

The ternary materials will become the key development products in the future. The lithium iron phosphate battery has high stability and low price, but it has limited energy density.

From the aspects of market usage, technology maturity, etc., the current domestic lithium battery is mainly made of lithium iron phosphate cathode material. This material has the characteristics of high stability, safety, reliability, low price, and mature technology, but the theoretical energy The limited space for density increase is up to 150Wh/kg.

From the perspective of domestic major power lithium battery companies: BYD has been insisting on lithium iron phosphate battery line, battery cell energy density reached 130Wh/kg or more, basically close to the theoretical limit, the company is also actively developing a higher energy density of phosphoric acid Lithium-manganese lithium new power lithium battery.

Tianjin Lishen products are mainly based on lithium iron phosphate batteries, and currently produce ternary material power lithium batteries in small batches; Guoxuan Hi-Tech always insists on lithium iron phosphate lithium batteries, mainly for JAC iEV series pure electric vehicles. , But the company also began to develop ternary materials power lithium battery.

The products of ATL, Harbin Coslight Power Supply Co., Ltd., Shenzhen Waterma, and China Aviation Lithium (Luoyang) Co., Ltd. are all mainly lithium iron phosphate batteries. However, they all have begun to pay attention to the development of ternary materials power lithium batteries. Lithium also began producing small-volume ternary power lithium batteries.

As the market is more optimistic about the ternary material power lithium battery, as the only company in the United States to do only three yuan material power lithium battery Boston Battery Co., Ltd., the company received a large number of orders in the first half of this year, but the company's oval cell structure design, and Panasonic's 18650 cylindrical batteries and BYD's large square-shell power lithium batteries have different shapes, and it is generally difficult to win approval from vehicle manufacturers.

In the future, in addition to ternary materials as key development products for power batteries, in order to increase the energy density of batteries, high energy density lithium-rich manganese-based cathode materials, high-voltage electrolytes, silicon-carbon anode materials, and graphite will also be developed. Ethylene materials and other materials.

The ternary material power lithium batteries mainly include nickel-cobalt-aluminum-lithium batteries, nickel-cobalt-manganese-manganese-lithium batteries, etc. The advantages are good high-temperature stability, good resistance to electrolyte corrosion, and theoretical energy density of 180 kW/kg or more, but product safety is consistent. The sexual aspect needs to be improved.
