Taking into account factors such as vehicle scrapping age and power battery
life, the cumulative scrapped power batteries nationwide will reach
120,000-200,000 tons from 2018 to 2020; by 2025, the annual scrapped power
battery volume may reach 350,000 tons.
In recent years, the development of new energy industry has been steadily
improving. Data from the China Automobile Association shows that from January to
April, the production and sales of new energy vehicles were 232,000 and 225,000
respectively, a year-on-year increase of 142.4% and 149.2% respectively.
Behind the gradually expanding new energy vehicle system, the demand for
power battery scrap recycling and reuse has also increased. According to the
forecast of the China Automotive Technology and Research Center, taking into
account factors such as vehicle scrappage age and power battery life, the
cumulative scrapped power batteries nationwide will reach 120,000-200,000 tons
from 2018 to 2020; by 2025, the annual scrapped power battery volume may reach
35,000 tons. Thousands of tons. In this regard, BAIC has stated that after the
power batteries are retired, if they are not disposed of properly, they are
likely to cause environmental pollution. Therefore, it is very important to
promote the recycling and resource processing of new energy vehicle power
batteries and establish a complete automobile circular economic system.
Battery recycling enters "special" mode
On February 26 this year, the "Interim Measures for the Management of
Recycling and Utilization of Power Batteries for New Energy Vehicles" jointly
issued by the Ministry of Industry and Information Technology, the Ministry of
Science and Technology, the Ministry of Transport, the Ministry of Commerce, the
General Administration of Quality Supervision, Inspection and Quarantine, and
the Energy Administration mentioned that the implementation of production The
extended liability system requires automobile manufacturers to assume the main
responsibility for recycling power batteries. This measure will take effect from
August 1 this year. Faced with the upcoming interim management measures, car
companies have begun to lay out their battery recycling business. Among them,
some car companies have chosen to cooperate with other companies to jointly
promote domestic power battery recycling and other related matters.
On January 4 this year, 16 complete vehicle and battery companies,
including Changan, BYD, and Yinlong New Energy, reached a cooperation with China
Tower Company, a major power battery recycling company, to solve problems such
as the recycling and reuse of retired power batteries. In March this year, SAIC
and CATL signed a memorandum of understanding on strategic cooperation,
intending to further deepen cooperation and discuss jointly promoting the
recycling and reuse of power batteries for new energy vehicles. This is also the
second "marriage" between SAIC and CATL after announcing the establishment of a
battery joint venture in 2017.
In addition, Beijing BAIC Penglong Automobile Service and Trading Co.,
Ltd., a subsidiary of BAIC Group, recently signed the "Strategic Cooperation
Framework Agreement on the Recycling and Utilization of Retired Power Batteries"
with GEM Co., Ltd. to jointly build a new energy vehicle power battery recycling
system. Cooperation in circular economy fields such as cascade utilization of
decommissioned power batteries, resource treatment of used batteries, recycling,
dismantling and recycling of scrap cars.
Battery processing technology and supervision still need to be improved
The reporter learned that since 2012, policies and guidance covering power
battery recycling and dismantling have been released almost every year. However,
power battery recycling and other related industries are still in their infancy.
In addition, so far, only a few car companies have carried out relevant layouts.
Both market size and processing technology will take time to improve.
Li Wenhai, member of the National Committee of the Chinese People's
Political Consultative Conference and deputy director of the Standing Committee
of the People's Congress of Jinnan District, Tianjin, pointed out that my
country's new energy vehicle battery recycling is facing three major problems:
the small scale of the scrap battery recycling market, the low technical level,
and the untimely processing of scrap batteries. . In this regard, Li Wenhai put
forward three suggestions, including scientific treatment of rare resources,
realizing step-by-step recycling, turning waste into treasure, strengthening
scrap battery recycling market management, and introducing preferential policies
to support the recycling of scrap batteries for new energy vehicles.
Similarly, Cui Dongshu, secretary-general of the National Passenger Car
Market Information Association, also believes that key technologies such as
residual value assessment and health status assessment of decommissioned power
batteries are not yet mature, and the research and development of related
technologies for cascade utilization and recycling are relatively lagging
behind. Industry experts are required to collaborate to promote technological
innovation and application and break through technical difficulties.
“Different models have different battery designs, internal and external
structural designs, module connection methods, integration forms, etc. There are
differences. The same set of disassembly lines cannot be used to fit all battery
packs and internal modules, resulting in extremely inconvenient battery
disassembly. . Therefore, most processes are completed manually, but the skill
level of workers may affect the yield during battery recycling. Therefore, it is
also important to take measures and methods to ensure safety during battery
disassembly. "Cui Dongshu introduced to reporters.
