Danger and chance coexist -- waste power battery

"I just know that batteries have lifetime replacement, but don't know where the used batteries go." A few days ago, Beijing car owner Joe's new energy vehicle which is purchased in 2013 has shorten battery life problems. According to the manufacturer's policy of batteries to protect battery lifetime, he had to go to the 4s shop for the replacement. When the battery is removed, Joe gave birth to the question: how do they do with the old power battery?

This is not a Joe confusion of one man. China's first batch of new energy vehicles power battery replacement period, waste battery recycling, deal with the problem has been in the eyes.

In 2020, power battery will focus on "retired"

"As a new energy vehicles the most unique components, power battery service life relatively much shorter compared with other parts inside the car, in general use fixed number of year for five to eight years." Sichuan kai Yang auto group chairman Wang Jiaqi think, this means that the domestic first batch to enter the market of new energy vehicles, will gradually from the beginning of the year for power battery replacement period.

According to statistics, in 2017 China's new energy vehicle sales of 77.70000, as of the accumulated has about 1.8 million cars. According to the calculation, to around 2020, power battery replacement will usher in explosive growth.

The current domestic power battery is mainly lithium ion batteries, the composition of the anode materials is likely to cause heavy metal pollution, electrolyte has the very strong corrosion resistance and toxicity, easy to produce toxic chemicals." A 20 g cell phone batteries can be contaminated volume 3 standard swimming pool of water, if the abandoned land, can make 1 square kilometers land pollution 50 years or so." Yuhai Wang, a professor at the university of Beijing institute of technology has the same for lithium ion battery environmental hazards of materials for analysis. Much bigger, therefore, if the volume of new energy car battery random process there will be consequences.

Pilot use first, dismantling again

"Dealing with the waste power battery is very difficult, but, well used this" hot potato "can also be 'into'." In the national "863" plan to energy saving and new energy automobile major projects overall expert group expert Xiao ChengWei view, by 2020, new energy vehicles is expected to retire lithium battery about 50 GWH (electric power unit, 1 GWH = 1 million kilowatt hours), the market space of up to ten billion yuan level.

However, due to the large volume, complex components, power battery recycling face many restrictions and high technical threshold.

"Battery change from new energy cars, can make arrangement in use in the first place." Beijing new energy company relevant technical personnel told workers' daily reporter, according to the standard, power battery capacity attenuation to less than 70% of the rated capacity, no longer applies to new energy vehicles." But the chemical composition of the battery doesn't change, also can save some energy, thus collected can be discarded batteries, where the request is not high." The technical personnel introduces, this is called "pilot".

"But let recycling party fret that this approach requires the waste battery model and parameter are basically identical, can together." Introduced the technique, researchers say, because our country does not have the unification of the power battery standard, there are difficulty to be used to a wide range of concentration.

According to introducing, retired control battery is arrangement in using the technology of quality and safety of the difficulty, must develop related detection technology and equipment, in order to accurately determine retired battery can enter the pilot use market, and determine the application scenario.

Reporters found that up to now, our country has not yet been large power battery recycling. Investigate its reason, is the cost of retrieving and dismantling value beyond the battery, the lack of profit.

Companies to take responsible, policy support

In march of this year, the Shenzhen municipal development and reform commission issued the Shenzhen city to carry out the country's new energy vehicle power battery recycling regulation system construction of pilot work plan. Previously, the ministry and other seven ministries jointly issued "the new energy vehicle power battery recycling management interim measures". Both clearly put car companies and power battery producer responsibility to extend to battery recycling. These policies developed are reversed transmission related businesses.

Beijing new energy from "optimus prime plan" was introduced last year, plans to invest 10 billion yuan in 2022, built a 3000 - seat light store across the country in power plant, the cumulative drop in 500000 electric vehicles, pilot energy storage battery with more than 5 GWH.

"Battery life" as a selling point, one of the BYD company, entrust the 4 s shop will back to factory inspection, after the waste battery recycling is thus decided to continue to use or take wet recycling and dismantling. As a result of the recycling are the same type of power battery, BYD in the pilot use has the very big convenience.

"Whether pilot use or recycling and dismantling, the premise is to monitor the flow of waste battery, ensure the inflows have technology, qualified manufacturers, in this way can the industry healthy and orderly operation." In the country during the two sessions this year, the National People's Congress, Shanghai automotive group chairman Chen Hong's recommendation, in social credit system, to increase the new energy automobile owners power battery code information. Battery recycling after report by recycling enterprise management institutions, regularly update the personal credit information, to prevent the owner to remove the battery and illegal to sell in the market.
