Lithium battery pack recycling

About the recycling of lithium battery packs. The energy stored in lithium battery packs is limited. After a long cycle, the energy contained in the interior will gradually decay.

When the energy in the lithium battery pack is attenuated to a certain extent, it is not able to meet the supply required by the current load, that is, the lithium battery pack needs to be recycled.

Regarding the recycling and disposal of lithium battery packs, the recycling market is still not perfect enough, but the market policy is also to deal with the recovery of lithium battery packs as much as possible. After all, lithium battery packs There are many applications. If the discarded lithium battery pack has no channels for processing, it will not only waste resources, but also affect the environment.

Lithium battery pack recycling method

The lithium battery pack can be selected according to the degree of scrapping. The lithium battery pack with high scrapping degree is selected for recycling and disassembly, and the available materials are collected and put into production. The low scraping degree can be used for the ladder utilization, and the energy is required. The lower field is put into use and reused according to the energy ladder.

▼Material recovery

For lithium battery packs that are no longer able to meet the current application requirements, recycling can effectively exert its 'residual value'. For lithium batteries with significantly reduced cycle life, renewable resources such as metal oxides, organic electrolytes, and plastic casings can be extracted. Recycling can effectively recover the cost of lithium batteries and has strong economics.

The battery core accounts for 36% of the cost of the power lithium battery pack. If the gross profit is deducted, the battery core ratio is as high as 49%; in the consumer battery, the cost of the battery core is higher. In the battery core, it is rich in nickel and cobalt. The cost of the cathode material of metal elements such as manganese accounts for 45%. Through the recovery of raw materials, metal elements such as nickel, cobalt and manganese can achieve a recovery rate of more than 95%, and the recovery rate of lithium elements is also above 70%, with significant economic benefits.

▼Step use

Lithium battery packs whose capacity cannot meet the current conditions of use, but have a long cycle life, can be used in the energy storage field through the ladder utilization mode. The ladder utilization is an efficient and energy-saving recycling method applicable to the waste power lithium battery pack, by extending Power lithium battery packs use the term to achieve economic goals.

In general, when the capacity of the power lithium battery pack is reduced to about 80%, it will be eliminated, but the power lithium battery pack can still be used for energy storage equipment, and put into commercial residential energy storage stations, electric vehicle charging and storage. Stations and telecommunications base stations.

For the recycling method of lithium battery packs, the resource utilization rate is generally higher by using the ladder utilization method, because the lithium battery pack has a longer cycle life and better energy storage utilization effect. However, the method for recycling lithium battery packs on the market now. It is still not perfect. It is not easy to use this method for the ladder. However, the lithium battery pack is used in a large market, and the recycling market will also develop.
