Power batteries usher in the "scrap tide" and the recycling industry brings an opportunity period

in recent years, the market ownership of new energy vehicles in China is increasing day by day, while the consumption of power batteries, as the core of new energy vehicles, is rising. The service life of power battery is generally 5 to 8 years. Industry insiders predict that the first batch of automotive power batteries entering the market in China will usher in a "scrap wave" from 2018

Sun Zhi, Research Institute of Institute of process engineering, Chinese Academy of Sciences, told China United Business Daily that waste power batteries contain a large number of valuable elements and substances with significant pollution characteristics. We should be alert to the "secondary pollution" caused by the tide of waste power batteries

according to the prediction of China Automotive Technology Research Center, from 2018 to 2020, the cumulative scrapped power batteries in China will reach 120000-200000 tons; By 2025, the annual waste of power batteries may reach 350000 tons. The centralized "decommissioning" of waste power batteries has brought opportunities to the recycling industry

the number of waste power batteries surged

since 2014, China's new energy vehicle market has shown a rapid development trend. According to the data, in 2016, the production and sales of new energy vehicles in China were 517000 and 507000 respectively, with a year-on-year increase of 51.7% and 53%. In 2017, China's new energy vehicles once again achieved high-speed growth, with 790000 and 780000 production and sales respectively, an increase of 53.8% and 53.3% year-on-year

by the end of 2017, the number of new energy vehicles in the country had reached 1.53 million. China has become a real big country in the production and marketing of new energy vehicles

it is worth noting that the warranty period of electric vehicle batteries is generally 5 to 8 years, and the first batch of electric vehicle batteries on the market have entered the "retirement period"

according to media reports, by 2020, the demand for power batteries in China will reach 125gwh, and the scrap volume will reach 32gwh, about 500000 tons; By 2023, the scrap volume will reach 101gwh, about 1.16 million tons

experts said that the improper and effective disposal of waste power batteries will threaten the environment and human health and affect the sustainable development of society

at present, power batteries are mainly lithium-ion and lead-acid batteries. Cadmium and lead in lead-acid batteries are heavy metals themselves. Some recycling stations disassemble the batteries, pour out the acid that pollutes the environment, disassemble and recycle lead privately, and then sell them to some small smelters or workshops at a high price for unprofessional treatment

lithium batteries are called "green batteries" because they do not contain mercury, cadmium, lead and other toxic heavy metals, but this does not mean that they are absolutely pollution-free products. In fact, the cathode material of power lithium battery may cause heavy metal pollution, and the electrolyte is also highly corrosive and toxic, which is easy to produce toxic chemical gases, which is also harmful to human health

insiders said that the performance of the power battery decays with the increase of charging times. When the battery capacity decays to less than 80% of the rated capacity, the power battery is no longer suitable for electric vehicles

automobile expert Jia Xinguang said in an interview that the main problem now is not reuse, but batch utilization. It cannot be used in cars, but can be used for energy storage. At present, internationally, Christodouleas said in many countries: "Take bubble bags to pretend to be container batteries for energy storage batteries, household photovoltaic, wind power generation, etc.

insiders also said that after testing, maintenance, reorganization and other links, the retired batteries can still be further used in energy storage, distributed photovoltaic power generation, household electricity, low-speed electric vehicles and many other fields. When the batteries cannot be used in echelons, they need to be recycled and disassembled for resource treatment.

because Therefore, power battery recycling has become an urgent problem to be solved in China

car companies accelerate the layout of recycling industry

the market is expected to peak in the domestic power battery waste recycling market this year and next year. How to recycle batteries, whether they can be effectively reused, and who should be responsible for the whole life cycle of power batteries have become the focus of academic and industry attention, and also the hot issues of countless electric vehicle users

zhuweihua, Deputy Secretary General of the Automotive Information Service Committee of the China Association of automobile manufacturers, believes that the residual value of the currently produced energy vehicles after five years of use is only 20%, and battery recycling is what car companies must do

the recycling of waste power batteries also has great potential? C1004 economic value of materials added to eye or face firming products to diagnose, treat, repair or replace damaged tissues and organs of organisms or promote their functions. According to industry estimates, in 2018, the waste power battery recycling market will reach a scale of 5billion yuan. From 2020 to 2023, the waste power battery recycling market will further grow to 13.6 billion yuan -31.1 billion yuan. The leading enterprises that take the lead in this field may be expected to get a big cake

in the past two years, the market scale has expanded rapidly, and the national policies have been continuously favorable. Since 2016, relevant national departments have successively issued the implementation plan of the extended producer system and the specification for the recycling and dismantling of vehicle power batteries

in February this year, the Ministry of industry and information technology, the Ministry of science and technology, the Ministry of environmental protection and other seven ministries and commissions jointly issued the Interim Measures for the management of the recycling of new energy vehicle power batteries, which has been implemented since August 1, 2018, stipulating that waste power batteries generated in the process of production, use, utilization, storage and transportation should be recycled

according to the measures, automobile production enterprises should be the main body of recycling, establish power battery recycling channels, be responsible for recycling waste power batteries generated after the use and scrapping of new energy vehicles, and establish after-sales maintenance service networks. The measures encourage automobile manufacturing enterprises to take various ways to provide convenient and fast recycling services for owners of new energy vehicles, and improve the enthusiasm of car owners to hand over waste power batteries through repurchase, trade in, subsidies and other measures

in addition, the Ministry of industry and information technology and others will release the pilot implementation plan for the recycling of power batteries of new energy vehicles in the near future, launch the pilot demonstration, support local and enterprises with conditions to try first, and cultivate a number of benchmark enterprises for the recycling of power batteries

facing the management measures to be implemented soon, the huge temptation of "cake" and the corresponding society, car enterprises began to layout the battery recycling business. Among them, some car companies choose to cooperate with other companies to jointly promote the recycling and reuse of domestic power batteries and other related matters

on January 4 this year, 16 vehicle and battery enterprises including Chang'an, BYD and Yinlong new energy reached a cooperation with China Iron Tower Corporation, a major power battery recycling company, to solve the recycling and reuse of retired power batteries

in March this year, SAIC Motor Group and Ningde times signed a memorandum of understanding on strategic cooperation, which plans to further deepen cooperation and discuss the following are summarized by the manufacturer's technology department through the manufacturer to jointly promote the recycling and reuse of new energy vehicle power batteries. This is also the second "marriage" between SAIC and Ningde times after the announcement of the establishment of a battery joint venture in 2017

on May 8, greenmead announced that at the R & D base of BAIC Group Co., Ltd., Beijing BAIC Penglong Automobile Service Trade Co., Ltd. signed the strategic cooperation framework agreement on the recycling of retired power batteries with greenmead. The two sides will carry out in-depth cooperation in the areas of circular economy such as the co construction of new energy vehicle power battery recycling system, the echelon utilization of retired power batteries, the resource treatment of waste batteries, the recycling, dismantling and recycling of end-of-life vehicles, as well as the sales and after-sales services of new energy vehicles, so as to jointly promote the healthy, green and sustainable development of China's new energy vehicle industry
