Three major problems of power lithium battery recycling -Lithium - Ion Battery Equipment
Recently, the Ministry of Industry and Information Technology has publicly solicited opinions on the "Requirements for the Review of Access Licenses for Road Motor Vehicle Manufacturers (Draft for Comment)" and the "Requirements for the Review of Access Licenses for Road Motor Vehicle Products (Draft for Comments)", proposing that enterprises should build used power batteries Stable recycling channels ensure the safe recycling of used power batteries.
In the process of scrap recycling of power batteries, whether it is cascade utilization or recycling of raw materials, the support of the main body of recycling is required, but at present, the reality is not ideal. So why is power battery recycling a problem?
Recycling main body is missing
According to the characteristics of power batteries and the principle of recycling, my country currently advocates the principle of first-level utilization of retired power batteries before they are scrapped and recycled, and requires OEMs to take the responsibility for power battery recycling as the main body of power battery recycling. However, since most vehicle companies are only "assembly plants" for electric vehicles, and batteries are provided by specialized battery companies, there is a phenomenon that three types of power battery recycling entities coexist: the first type is vehicle enterprises; The second category is battery production enterprises; the third category is power battery scrap recycling and processing enterprises and raw material enterprises.(Lithium - Ion Battery Equipment)
"According to regulations, auto companies should assume the main responsibility for recycling, but car companies are not omnipotent." Cui Dongshu, secretary general of the National Passenger Vehicle Market Information Joint Association, said that to a certain extent, car companies are more like "assembly plants" for electric vehicles. , responsible for the normal use of batteries, production supply, secondary utilization and recycling during the warranty period, but it is the expertise of battery companies. “I think who sells batteries and who is responsible for batteries should at least cooperate. Unfortunately, battery companies are often excluded from the recycling system, and the responsibility is not clear at present.”
Recycling technology bottleneck to be broken
Due to its large size and complex composition, the recycling and reuse of power batteries faces many limitations and high technical thresholds.
Due to the large differences in the types, specifications, and processes of retired batteries, and the diversity of series and parallel group forms, application models, use times and working conditions, the dismantling is complicated. At the same time, my country has not issued a unified standard for power batteries, and it is still difficult to use it on a large scale.
From the point of view of recycled batteries alone, even lithium batteries have various cathode materials. The mainstream ones are lithium cobalt oxide, lithium manganate, lithium nickel cobalt manganate, lithium iron phosphate, etc. The metal oxide is extracted by leaching with acid-base solution and then through various chemical procedures. However, the extraction conditions of the components of these oxides are different, and the mixture is more difficult.
Recycling mode uncertain
Despite a difficult start, the prospects are generally optimistic in the industry. Overall, the current large-scale "retirement tide" of power batteries has not yet arrived, and it is difficult to form a large-scale effect for the dismantling and recycling of power batteries.
For example, some car companies choose to cooperate with other companies to jointly promote domestic power battery recycling and other related matters. Changan, BYD, Yinlong New Energy and other 16 vehicle and battery companies have reached cooperation with China Tower, a major power battery recycling company, to solve problems such as recycling and reuse of retired power batteries.
In addition to vehicle companies, battery manufacturers have also actively explored this. Ningde Times, AVIC Lithium Battery, BAK Battery, Guoxuan Hi-Tech and other companies have established battery recycling networks and began to deploy power battery recycling business. There are also institutional forecasts. , the power battery recycling market will form a new "air outlet" of 10 billion yuan. This is also the reason why, in addition to car companies, battery companies, and raw material recycling companies, capital is also aggressively entering this field, and they are also seeking new opportunities in this field.
