Attention: power battery recycling channels construction into the critical period

In the new energy automotive industry prosperity and development at the same time, Power battery Recycling problem has become the focus of the industry. After recent years of development, new energy vehicles batch BAOFEIQI will come. If a large number of retired battery unable to recycle properly, which not only lead to a waste of resources,also bring the environmental pollution and other issues.

"Accompanied by automobile enterprise as the main body of the establishment of the production responsibility system, power battery recycling industry has stepped into a key period of channel construction."Ministry of energy saving and comprehensive utilization department, former deputy inspector, secretary general of the China electronic energy-saving technology association, an April 17 in the 7th auto motive battery recycling and secondary battery recycling and regeneration technology seminar, said on the design of the power battery production in China and waste power battery recycling disposal and comprehensive utilization are currently in need of support, standardization of preliminary stage of development.

Industry pain points: the high cost  high and the weak economy

"New energy vehicle retirement period is for 5 years normally, passenger cars and commercial vehicles are for 3 years."China battery union Yang Qingyu  predicted at the scene of the meeting, "before 2022, retired in battery lithium iron phosphate batteries is given priority to, 2022 years later The ternary battery With the amount of retirement is flat, lithium iron phosphate and gradually ahead."

Yang Qingyu further pointed out that the theory of power battery of the whole year of 2018 retired volume is expected to be 5.14 GWH, retired as main sources of new energy bus.

The reporter understands, at present already layout related business enterprises are divided into five types: traditional recycling companies, recycling emerging enterprises, battery, battery PACK plant materials and OEMS.

"The advantages and disadvantages of different types of enterprises have difference. Such as traditional recycling enterprises in recycling channels, material regeneration technology, cell crushing technology and smelting technology on the relative advantage, but because of lack of power battery source itself, still need to cooperate with OEMS, scrap factory. Advantage of emerging recycling enterprise is mainly in battery broken and dismantling technology."Yang Qingyu added.

The main processing methods currently used power battery are fire smelting technology and wet smelting technology. Mining and metallurgy technology group co., LTD., Beijing metallurgical research and design institute director WangHaibei said that the existing technology of smelting process is very complex, the difficulty coefficient are very large.

"Recycling system to smooth running of the profit as the premise, without profit drive, will not be able to fully motivate enterprises." WangHaibei admitted that "the existing recycling technology investment and recycling network construction investment is very big, although many enterprises layout, but few have struck gold."

Not allow to ignore, battery recycling process will produce toxicity of electrolyte and harmful gas, if not handled properly will bring great harms to environment and human health."Some enterprises in the process with the method of high temperature heating or burning, controls the lax easily harm to workers health."Harbin bars resource recycling technology co., LTD general manager MingYue bin is pointed out.

Force to seek government enterprises

To solve above problems, the national related department has issued a series of industry policy, to guide and regulate the power battery recycling industry.

In February this year, seven ministries jointly issued by the ministry of industry and new energy vehicle power battery recycling management interim measures ", clear the body of the auto production enterprises to assume power battery recycling. In march, the ministry and other seven ministries jointly issued "on the organization carries out the new energy vehicle power battery recycling pilot work notice, is put forward in Beijing –Tianjin – Hebei ,Yangtze river delta, the pearl river delta, central select parts such as area, to carry out pilot, power battery recycling to the pilot as the center, radiation to the surrounding areas.

"The notice issued by marks our recycling policy system is gradually built."Yang Qingyu thinks, "as related technical breakthrough, policy will accelerate the release speed, related standards and is estimated to be released this year."

According to the guests, now the new energy car battery type, battery capacity and voltage platform there is a big difference, this is power battery arrangement in use of the first hurdles facing, so how to scientifically evaluate retired battery has become decided to battery "where" the first level.

Evaluation process is mainly "retired batteries is, online and offline data were collected and uploaded to the monitoring platform, so as to analyze the battery pack processing and evaluating performance."Battery technology co., LTD. Beijing as core technical director lee pointed out that from the point of evaluation results, three yuan pilot use value is greater than the direct dismantling of the battery.

According to introducing, retired after assessment is eligible, battery arrangement can be made using the link, the power energy storage system to improve the overall efficiency, maximize the cycle life of lithium-ion batteries. There are a lot of enterprises to carry out the pilot demonstration projects.

Shanghai xian da new energy technology co., LTD. Zhang feeds marketing vice President told reporters: "the original forecast cell arrangement in using the attenuation rates from 3% to 5%, but through the actual operation of the project, to get rid of the cold weather in, most of the charge and discharge data showed no attenuation, even lower than the attenuation of new batteries."

For the treatment of toxic gases, MingYue bin is that assembly lines machinery and equipment, can be used for cell and module in whole crushing processing, will be the overall recycling, electrolyte USES the separation technology of material, is the cathode powder separation, and the metal shell is obtained."Because the diaphragm is fully recovered, so will not be harmful gas."She added.

Depth cooperation polishing industry chain

It is understood that power battery recycling system in car companies, battery production, battery recycling enterprises, and other stakeholders, the chain is longer, there are still many difficulties in the process of actual operation. Jiang xi feng cycle technology co., LTD., general manager of XieShaozhong advise: “Industrial chain each link needs to adjust, but the overall principle should be" professional people do professional thing ".By automobile companies set up recycling channels, for example, recovery after to the comprehensive utilization of professional processing enterprises, the industrial chain each link all depth cooperation."

It is understood that there are many companies layout power battery recycling this piece of blue ocean:

At the end of 2017, Beijing new energy released " Optimus prime plan" : in 2022, is expected to invest 10 billion YUAN to build 3000 across the country light store in power station, the cumulative drop in 500000 sets of electric vehicles, pilot Energy storage battery With more than 5 GWH.

In January 2018, the tower companies in China with Thornton group 16 companies such as new energy vehicle power battery recycling strategic partner agreement. Tower companies in China will adopt a pure electric bus power battery was discharged, after testing, sorting and restructuring, instead of lead-acid batteries are used for communication base station can prepare.

"Both in car companies and power battery enterprise, in the advanced concept of producer responsibility in an effort to practice. Hope all participants from corporate social responsibility perspective, exploring suited to the characteristics of the industry, enterprise, product pattern, the mechanism of power battery recycling."An points in, "if the nods eyeball pen of power battery are cascade utilization and recycling of recycling the establishment of the model and mechanism will be its genius."
