How do you deal with the waste batteries of new energy vehicles?

The development of China's new energy vehicles, can be used to describe a "quick" word.Power lithium battery reuse refers to between the new energy vehicles and power lithium battery utilization of the intermediate links, through to the car after use power battery after disassembly, detection and classification of secondary use, realize the power battery cascade, so as to realize power battery 30-60% of the cost reduction purposes.In general, with the standard of new energy vehicles power lithium battery scrap is the battery capacity is less than 80%, if the residual capacity in 70-80% battery directly recycling is a great waste recycling, and completes the power lithium battery recycling of batteries cost reduction is especially important.

Problems to come.So fast speed of development, used batteries?At this point, and can be used to describe a "mess" word.

Waste lithium batteries have?

Analysts said, although a lot of new energy automobile enterprises commitment to consumer battery life and the quality can reach 8 years or so, but in li-ion battery service life of the 1500-2000 time charge calculation, the average life span for the power battery is 5-6 years.Vehicle power battery after retirement, if it is not necessary to recycle and treatment, not only will cause the waste of resources, will damage to the environment.

Accordingly, by 2020, demand of power battery in China will reach 125 GWH, scrap will amount to 32 GWH, about 500000 tons;By 2023, the scrap will reach 101 GWH, about 1.16 million tons.

Such a large number of scrap, explain our country power battery recycling has become urgent for solution of the problem, if the scrap battery disposal is undeserved, will cause irreparable harm to environment and human environment.

The harm of waste battery have how old?

Data shows, waste power battery is not appropriate and effective disposal, will threaten the environment and human health, affecting the social sustainable development.

At present, power battery is given priority to with lithium ion and lead-acid battery.Cadmium and lead in the lead-acid battery itself is heavy metal, some recycle bin unwrapped battery, pour out the environmental pollution of acid, to remove the lead recycling, to sell a small smelter at a high price or no professional processing small workshops.

Lithium battery is referred to as "green batteries", the reason is that do not contain mercury, cadmium, lead and other toxic heavy metal elements, but this does not mean that it is absolutely pollution-free products.In fact, there is power lithium battery cathode material, cause the possibility of heavy metal pollution, the electrolyte has the very strong corrosion resistance and toxicity, easy to produce toxic chemical gases, also harm to human health.

Chinese academy of engineering academician Yang once said: "all batteries are chemical, in waste battery treatment, if the system is lax, poor management, backward technology, can pollute the environment."

"A 20 g of mobile 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 said, "just think, if it is a few tons of electric vehicle power battery scrap in the natural environment, a large number of heavy metals and chemicals from entering the nature, will be how much pollution on the environment?"

"Power battery recycling is the immediate problem."School of environment, tsinghua university professor jin-hui li said.

Who in the recovery?

According to international practice, who are generally production, who is responsible for recycling.But a market participants told reporters, according to the current 90% recycling waste battery is not from the formal channels.

It is reported that there are more battery enterprise layout the battery recycling field, but most is limited to recycle the screening test, pilot in this stage, cell or battery.They is no layout in dismantling link, because dismantling link in waste batteries, the most critical and most likely to cause pollution, to apply for a permit, need technical and financial support.

More to the last link of battery enterprises deal is commonly: for battery recycling enterprises to carry out dismantling.

Battery recycling enterprise is divided into two kinds: one kind is professional, with recovery of qualifications of enterprises;Is a kind of outdated technology, no qualification of enterprises.The problem is that no qualification of enterprises in order to profit, their recycling prices too high, so they took away more waste batteries.

On the processing of waste battery, no recovery qualification enterprise, due to technical, most of them regardless of environmental pollution disposing used batteries, any emissions.It not only disturb was not the size of the market, and buried under the great environment and safe hidden trouble.

Chaos remained

New energy vehicles destroyed traditional fuel vehicle emissions to the atmosphere of the dye, but after using waste battery pollution to the environment and bring new topics to the society.Policy in spare no effort to make all kinds of subsidy programs and guidance, but still a long way to go.

Reporters in shenzhen area of waste battery recycling conducted an investigation.Public access to information from the market, shenzhen only three companies with waste battery recycling certificate, respectively is beauty, shenzhen green recycling waste battery recycling depot, Thai force.

But ordinary citizens still can't find formal recycling channels.On August 30, citizens Ms. Peng: "there are a lot of dry cell in the home, don't know how to deal with?Downtown where there are recycling dry cell?"

Communities, she says, the roadside trash on a special recycling batteries of small grid, wanted to throw waste batteries inside, but later found the cleaner directly when life garbage disposal the waste batteries.

It is understood that the current market average disposable dry cell, basic for alkaline mercury-free batteries, but with living garbage disposal, don't need to do a special collection disposal.But the mix of rechargeable secondary battery or on the phoneLithium ion batteries, but will cause considerable pollution to the environment.

Overall, waste battery recycling of "chaos" is characterized by: late some enterprises regardless of the risk of liability, in order to small "high price" to sell the battery technology behind no qualification of small businesses;Ordinary people can't find formal recycling channels and so on.Need to solve all these problems.

Gratifying changes

Ancient Chinese philosophers thought, not only to know (" "), especially the practice (" "), only the "know" and "line" to unify, can be called "good".Now, the enterprise should also achieve unity, committed to the long-term healthy development.

On the national policy level, the current national standards about power battery product mainly has eight, centralized regulated power battery performance test requirements and methods, power battery safety test requirements and methods.Regard to the standard of power battery recycling, the published standards have two, four projects has been submitted to the approval of standards, there are 9 standard for the following plan.

At the enterprise level, the reporter noticed, on August 26, green beauty, deputy general manager of Pan Hua said in an interview with netease car, to create new energy materials circulation system, build the new energy of green supply chain, green beauty proposed "new energy power battery complete life cycle value chain", mainly is to link industry chain upstream and downstream, integrating the resource of the whole industry chain, formed from the production to the recycled chain win-win cooperation model.

Journalists and contacted the Thai company many times.Nassim company general manager Mr Zhang yx, Thai force for more than a decade is committed to environmental protection enterprise, devotes to the waste battery recycling, battery recycling aptitude is not known.

General zhang, power companies are stepping up efforts to waste battery recycling, waste battery recycling.In 2015, the company built 1 the annual output of 3500 tons of fully automatic lithium battery processing line;In June 2016, the company built 1 the waste electric cars of retrieving and dismantling line;At present, is planning to build an automatic waste battery treatment line, are expected to be put into use in 2018.

In terms of battery recycling, zhang always refers to the fact that consumers use of discarded batteries can also dial the hotline 400-888-6821, any consultation and find the nearest collection point, into the boxes.

Zhang said finally, battery recycling market this "cake" is very big, need capital investment is very big, return will be high.Nassim company currently has a plan to introduce strategic investors, the Thai company acquisitions are also possible solutions.Nassim company hopes that the investor has correlation with the new energy industry, can promote the healthy development of enterprises and industries.

In short, while recycling waste battery, GongZaiDangDai, cabinet.
