How to use waste lithium-ion batteries twice?

First, raw materials recycling. From a technical point of view, the recycling technology of the current waste lithium-ion battery is quite mature: first completely discharge, then disassemble the battery, separating the respective components of the positive electrode, negative electrode, electrolyte and diaphragm. The electrode material is leached, the acid is immersed, and the extraction is performed to achieve the enrichment of the viable metal, and the recovery rate of the element is close to 100%.

Second, the use of waste batteries. The waste battery capacity is attenuated, but there is still a certain energy storage capacity, the life cycle has not ended, and it can also be applied to the energy storage market, light electric vehicle, spare battery, etc. At present, many foreign car companies and institutions are exploring, such as alternate power supplies them as home or commercial buildings.

That is to use the solar charging during the day, take advantage of the trough electricity price to charge the electricity in the battery during the battery or emergency. The general car has such a practice, manufacturing a home spare power supply with 5 sets of Chevrolet Volt, filled with 3-5 US ordinary families for 2 hours after power failure. Prior to Tesla also explored the use of waste batteries, but this model relates to a wide range of people in the United States, and the single-family houses that live in the United States have some applicable scenes.

For those who live in the city, there are not many application scenarios, so there are some commercial institutions that focus on waste batteries. As a commercial institution, they collect their electricity networks. How is the use of domestic waste batteries? In order to promote the recycling of waste batteries, the Ministry of Industry and Information Technology announced in July, "Interim Provisions on the Management of New Energy Automobile Power Battery Recycling and Utilization", and officially implemented on August 1.

The important content of this traceability management is to standardize the processing, sales, scrap, recycling, and utilization of power lithium-ion batteries, and perform monitoring for the implementation of the subject's subject. From a technical point of view, the current recycling technology of the waste-driven lithium-ion battery has been quite mature, and the recovery of elements is close to 100%. The difficulty is important in the process of recycling.

In a sense, put it from the user, it may be difficult than subsequent processing.
