The economic benefits of the echelon utilization of retired power batteries will gradually appear

It is reported that whether the power battery can be properly recycled is a key link
in the true environmental protection of electric vehicles.
However, the current recycling of decommissioned power batteries, in addition to the policy system still needs to be improved, there are also some difficulties
in the economic and technical aspects.

There are many varieties of domestic lithium batteries, the battery structure is complex and there is no unified standard, the decommissioned battery to be used in the echelon, need to be disassembled, sorted and secondary grouping, the process is complex, and the recycled cells come from different manufacturers, or the specifications are different, which means that the battery PACK may require a variety of different designers Due to the above situation, the current cascade utilization of electric vehicle decommissioned power batteries is still at the theoretical level, although there are enterprises in the research of related aspects, but the practical application experience is not enough, therefore, There are still many problems
in the utilization of cascade in retired power batteries.

According to the experience of experts and technicians of waste battery recycling and treatment enterprises, the mechanical method and wet method are used to recycle waste lithium iron phosphate batteries, and the material recovery rate is calculated according to 90%, and the cost of recycling and processing waste lithium iron phosphate power batteries is higher than the income
of recycled materials.
The cost of recycling lithium carbonate from lithium batteries in China is more than 5 times the direct production cost of enterprises, which leads to a lack of enthusiasm for recycling, coupled with the government's lack of policies to encourage recycling, power battery recycling faces great difficulties
