The end of June, about new energy vehicle battery development seminar held in Beijing, the Ministry Minister, Miao Wei, and the Vice Minister of the Ministry at the same time to participate in.


At the meeting, in addition to the battery development strategy seminar, national battery innovation centers have also been established, dedicated capture key technology problem hindering the development of battery industry. On the eve of the outbreak of new-energy cars, this innovative Centre hopes.


Battery-necks


2015 new energy new energy car production more than 300,000 vehicles in China, and China has become the world's first new energy automobile market, 2020 market holdings is expected to reach 5 million units, production capacity will reach 2 million, demand for batteries exceed 100GWh. It is regrettable that, our production scale at a time of rapid expansion of new energy vehicles, batteries but could not keep up with the pace of research and development, has now become the bottleneck of the further development of new energy vehicles in China.
Beijing Nonferrous Metal Research Institute Xiong Baiqing, Deputy Director, told reporters that China's independent research and development of power battery is weak and expensive, which to a large extent, influence the penetration of new energy vehicles.


With a 1.5-ton new energy cars, for example, if one charge mileage 400 kilometers, under the current technology, only batteries weighing nearly 600 kg, battery manufacturing costs a 150,000-~20 million, coupled with the price of the car, an average of nearly 400,000 new energy vehicle price, consumers find it difficult to accept. The current situation, depends on the country's vast financial subsidies to support, but it's hard to long-term sustainability.


So how to make the battery weight at the same time, without reducing its power, and prices down, a test of battery technology breakthrough.
It is reported that domestic power battery exists of three main bottleneck: the first low specific energy; the second battery manufacturing costs are high; the third battery life not enough, probably 5-8 the battery will need to phase out.


The other hand, frequent explosions and burning of electric cars, let the battery's security problems are more severe. Security is the fundamental guarantee of the future development of new energy vehicles, batteries are critical joints. If you don't do the safe, reliable, will dampen consumer confidence, affect the entire industry.
