The power battery is the power source that provides the power source for the tool, and refers to the battery that powers the electric car, the electric train, the electric bicycle, and the golf cart. It is mainly distinguished from a starter battery for starting a car engine.

As the heart of electric vehicles, the development of technology affects the development of the entire electric vehicle industry. With the increasing sales of new energy vehicles, China's power battery industrialization has also made important progress.
"At the end of 2016, the energy density of China's power battery cells has reached 220 watt-hours/kg, and the price is as low as 1.5 yuan/watt hour. Compared with 2002, the energy density has increased by 1.7 times, the price has dropped by 60%, and the Pearl River Delta has been built. The Yangtze River Delta, Beijing-Tianjin-Hebei and Central China's four major battery industry clusters have become the world's largest power battery producers." Qi Guochun, deputy director of the Equipment Industry Department of the Ministry of Industry and Information Technology, said at the recent lithium industry international summit forum.
According to data released by China Electric Vehicles 100, in the first quarter of this year, the total demand for lithium-ion batteries for domestic electric vehicles was 1.27GWh, of which about 0.97GWh was used for pure electric vehicles, accounting for 76% of the total.
Ouyang Minggao, executive vice president of China Electric Vehicles 100, pointed out that in the next five years, market competition will mainly focus on the cost performance and technology of pure electric drive home mainstream cars, among which the competition between electric home mainstream cars and traditional fuel cars will The most intense, and this requires electric vehicles to reduce the cost of the premise of increasing mileage, so the performance improvement of the power battery is the key.
Overcapacity of production capacity
According to data from the China Association of Automobile Manufacturers (hereinafter referred to as the China Automobile Association), in the first five months of this year, the production and sales of new energy vehicles completed 147,000 and 136,000, an increase of 11.7% and 7.8% respectively. "China's new energy vehicle industry introduction period has basically ended, and now enters the growth period." Ouyang Minggao said, "Last year, China's new energy vehicles sold a total of 510,000 vehicles, accounting for 1.8% of total vehicle sales, and will continue to grow this year. The total sales volume is around 700,000 units."
In fact, the new energy vehicle market volume also allows the power battery companies to feel the market warmth. Data show that in the global power battery shipments last year, the Chinese market accounted for 65% of the market share, the entire vehicle power battery package reached 3.044 million kWh.
The reporter learned that according to incomplete statistics, the investment in the power battery program in 2015 was nearly 100 billion yuan. In the first half of last year alone, 54 companies released a total investment of 114 billion yuan to expand the production plan. 20 homes.
"As of the end of last year, China's power battery capacity has reached 120GWh, and may approach 200GWh by the end of this year, while the market demand is less than 40GWh. The pressure on enterprises is huge." Fang Jianhua, Partner and President of the New Energy Vehicle Venture Capital Fund of the National Science and Technology Achievement Transformation Fund It is said that with the rapid advancement of technology, the capacity built now may be a pile of scrap iron after two or three years.
It is understood that in 2015, among the 121 power battery companies in China, there are no more than 20 enterprises that actually enter the vehicle supply system. However, some analysts pointed out that at present, the two-stage differentiation of the power battery industry is serious, and the problem of low-level redundant construction is prominent. In the face of fierce price wars and falling profits, the power battery industry is ushered in a reshuffle. Enterprises with product technology advantages, production scale advantages and market share advantages will gain better growth space. Conversely, enterprises with poor product quality will Gradually eliminated.
High raw material costs
"In the era of pure electric drive, our main goal is to make the electric home mainstream car cost-effective, and this will be the most competitive field between electric cars and traditional fuel cars." Ouyang Minggao said, "Value for money means mileage. The cost ratio is to strictly control costs while improving mileage."
It is understood that power batteries account for 30% to 40% of the cost of new energy vehicle manufacturing. New energy vehicles must have more price advantages and become competitive. They must reduce the cost of power batteries and improve the cost performance. Ouyang Minggao pointed out that reducing the cost of power batteries requires the development of the entire industry chain, and should first break through the raw materials. "At present, the cost of raw materials remains high. The reasonable price of lithium carbonate should be 30,000 to 50,000 yuan / ton, but now it is as high as 170,000 yuan / ton. If the price of raw materials is reasonable, the cost of power batteries will be reduced."
In addition, in terms of power battery performance, the specific energy needs to be increased from the current 180 watt-hours/kg to 300 watt-hours/kg in 2020. Once it reaches 500-600 watt-hours/liter, it can meet the needs of various types of electric cars.
"If the internal combustion engine power system is equivalent to the new battery power system, 100 US dollars (about 680 yuan) / kWh, it can be equivalent to the traditional internal combustion engine power, and our next stage goal is to reach 1,000 yuan in 2020. / kWh." Ouyang Minggao said.
It is reported that as of the end of last year, the energy density of power battery cells has reached 220 watt-hours/kg, and the price is as low as 1.5 yuan/watt hour, which is 1.7 times higher than the energy density in 2002, and the price is reduced by 60%. Some insiders said that the charging time is 10 minutes, the cruising range is 500 kilometers, the battery capacity is 100 degrees, and the fast charging power is 350 kilowatts. This is not only a technical threshold, but also a new challenge facing the whole industry.
