In recent years, with China's strong support, China's new power car industry expanded rapidly, especially since the beginning of 2014, the market has increased explosive. According to the China automobile industry association data, in 2016, China's new power car sales reached 507 thousand vehicles, shopping malls tired measurement reached 1 million. New electric cars as a national "13th Five-Year" new strategic industries, is estimated to be expanded further.
Batteries that need to be dealt with, and the use of car power batteries, is 5-8 years old, which means that, starting in 2018, China's first batch of new power cars, which enter the market, will face the question of void recovery. It is predicted that by 2020, China vehicle power battery total will reach 200 thousand tons of void volume estimates of the planning, and with the new power car and the passage of time, the battery back pressure will become increasingly large, the void of power batteries how to recover the use, will affect the key new power car launch. According to the calculation, in 2015 the cumulative power battery 20 thousand ~4 million tons, the corresponding battery recovery rate of only 2%, to now the recovery capacity, unable to shoulder the 2020 estimate of 120 thousand ~17 tons of obsolete batteries. Therefore, there are many problems that need to be dealt with urgently, such as the construction of the reuse management system, the leading technological innovation, the form exploration, and the standardization of the system construction.
A lot of damage to the battery is abandoned. Discarded batteries constitute capital, power, waste, and environmental pollution. The path to environmental and human health damage by chemicals in used batteries is shown in the figure above. Beijing Institute of Technology professor Wu Feng has revealed: "1 20 grams of mobile phone batteries can pollute 3 standard swimming pool volume of water, if abandoned in the land, can make 1 square square land pollution for about 50 years.". Just imagine, if a few tons of electric cars, power batteries abandoned in the natural environment, a lot of heavy metals and chemicals into nature, will constitute a greater pollution of the environment." In fact, China vehicle power battery mostly for lithium ion batteries, although do not contain mercury, cadmium, lead and other toxic heavy metal elements, but just as professor Wu Feng said, the waste lithium ion battery if not properly handled will pose great pollution to the environment.
Battery recovery dilemma at the beginning of this year, the Ministry of Commerce, Ministry of science and technology to accelerate the release of "guidance opinion" regeneration of capital industry expansion, which emphasizes "the launch of a new car battery power recovery pilot, establish and improve the system of norms of waste battery capital, promote waste battery cascade use". But now the power battery recovery than production more messy, because the automation level is low, an expert fee, so that waste batteries dismantling the cost is also beyond the new battery cost. And the recovery of power batteries, there is no reasonable direction of use, only the use of switching power plants and voltage divider, but the amount of use is not large, and the economic benefits are difficult to complete. Recovery, dismantling costs higher, poor economic, but also to some extent restricted the battery recovery company's enthusiasm. According to the National Academy of engineering, former vice president of Chinese manufacturing innovation center expert group leader Gan Yong said, lithium battery factory 1 million kilowatts domestic production capacity at about 10, under the production capacity of the company can be reached at least 4, 500. Unlike manufacturers of lithium battery data and formulations vary, it is harder to end the recovery.
Summary of domestic battery battery variety, messy construction and have no fixed standard, constitute the dismantling technology to recover the clutter, recover the high cost, lack of recovery of enthusiasm, cannot form industrialized operation, and the recombinant techniques are not, combined with the government's lack of supervision and encouragement policy, the power battery back in the face of great difficulties. Now the domestic car battery to recover the overall operation of industrial form is still in the exploratory stage, now in urgent need of government intervention in the development of guidelines and establish the standard system to guide the company to gradually expand the road to health. It also requires an industrial alliance between the industrial and downstream industries to establish a healthy industrial chain and find viable surplus points to support the rapid and sustained expansion of China's new power car industry.
