Three puzzles recovered by power lithium ion battery

According to the principle of dynamic lithium-ion battery, the principle of recycling of retired dynamic lithium-ion batteries in my country is currently advocating the principle of retransal recycling, and requires the vehicle as the main body of the power lithium-ion battery, and takes responsibility for power lithium-ion battery recovery responsibility. However, due to most of the vehicle company is only the assembly plant of electric cars, the battery is supplied by specialized battery companies, which has the phenomenon of power lithium-ion battery recovery three types of main body: The first class is the vehicle company; Second category is battery processing company; third category is a power lithium-ion battery scrap recovery solution company and raw material company. According to the regulations, the automotive company should bear the responsibility of the recovery, but the car companies are not universal.

Cui Dongshu, secretary-general of the National Passenger Car Market Information, said, to some extent, car enterprise is more like an electric car assembly factory, responsible for battery use in the warranty period, processing supply, secondary use and recycling, but Battery company expertise. I think who sells the battery, who is responsible for the battery, at least in both parties. Unfortunately, battery companies are often excluded from the recycling system, and the responsibility is still unclear.

Recycling technology bottleneck is to be broken due to large volume, complicated component complex, dynamic lithium-ion battery recovery and re-use facing many restrictions and higher technical thresholds. Due to the type, specifications, process, etc. of the retired battery, and in series, in series, the use of models, usage time and conditions, resulting in downtime complexity.

At the same time, there is no unified standard for the power lithium-ion battery, and there is still difficult to use a wide range of gathering. From the recovery battery, even if the lithium ion battery, the positive electrode material is also a five-flowers, the mainstream is lithium cobaltate, lithium manganate, and lithium iron phosphate, etc. Using a solution of acid-base solution, then the metal oxide is extracted with a variety of chemical procedures.

However, the ingredients of these oxides are different, and the mixture is more difficult. Recycling mode is uncertain, although it is difficult to start, the prospect is generally optimized in the industry. Overall, the massive retirement tide of the current dynamic lithium-ion battery has not yet arrived, and the dynamic lithium-ion battery dismantling recovery is difficult to form a scale effect.

For example, some car companies choose to cooperate in the form of cooperation, join hands to promote the recycling of domestic power lithium-ion batteries together. 16 vehicles such as Changan, BYD, Yinlong New Energy, etc.
