Lithium batteries as the main development direction

At present, batteries are widely used in mobile and energy storage equipment. According to relevant data, the total output value of the domestic battery industry in 2011 increased by 35.4 % year-on-year, reaching 564.5 billion yuan.

Due to the constant development of the concept of energy conservation and environmental protection, and the continuous updating of new technologies, the performance of the product determines the general trend of product substitution. When we looked at the data, we found that the substitution process of a battery showed that the dry battery was replaced by an alkaline battery and the alkaline battery was replaced by a lithium primary battery. The alternative process of the secondary battery is that the lead-acid battery is replaced by a nickel-cadmium battery, the nickel-cadmium battery is replaced by a nickel-metal hydride battery, and the nickel-metal hydride battery is replaced by a lithium-ion battery.

At present, there are two directions for new energy car batteries, one for fuel cells and the other for lithium batteries, according to experts in the industry who have been reluctant to name names. The so-called fuel cell refers to a power generation device that directly converts the chemistry stored in fuels and oxidants into electricity. Fuel and air are sent to fuel cells to generate electricity.

According to our understanding, although fuel cells once had a large voice, in March 2012, the Ministry of Science and Technology issued the "Twelfth Five-Year Plan for the Development of Electric Vehicle Science and Technology"(hereinafter referred to as "the plan") clearly stated that the focus is on the study of new lithium ion power batteries. The "plan" also proposed that with the power battery module as the core, we must achieve a large-scale industrial breakthrough of automotive power batteries with the focus on energy-type lithium-ion power batteries in China. From this point of view, lithium-ion batteries have long been clearly defined as the development direction of new energy car batteries.

At present, China's listed companies involved in lithium batteries, BYD, Shuguang shares, Chengfei integration, Desai battery, Xinzhoubang, Tianqi lithium industry are generally optimistic. Some analysts believe that the new energy vehicle plan will definitely benefit the relevant industries.

According to Huachang Securities analysis, in 2015, 500,000 new energy vehicles pulled 6 billion WH(watt-hour) demand and 9 billion yuan in market value space, contributing 10 % of the annual composite growth rate for lithium batteries, plus electronic and electric bicycles. The battery industry can maintain a compound growth rate of about 25 % within five years, but due to the fierce competition in the supply of the industry, companies do not have opportunities to explode and can grow steadily.
