6 FAQs about [Waste of positive and negative electrode materials of lithium batteries]

What are the waste lithium-ion battery electrode materials used in this study?

The waste lithium-ion battery electrode materials used in this study were procured from the electronic market. The obtained lithium-ion battery electrode powder underwent sieving with a 100-mesh sieve to eliminate impurities like battery plastic packaging.

How to recycle lithium ion batteries?

The electrode material is generally adhered to the current collector with a binder in waste lithium-ion batteries. The separation of active materials and current collectors in high purity is a critical prerequisite for the recycling of spent LIBs.

Why are lithium ions embedded in spent materials after electrochemical repair?

Lithium ions are embedded in the spent materials under the action of electric current. The capacity of spent materials after electrochemical repair is low (Table 3), which is likely to be due to the SEI film on the surface of the spent materials hindering the replenishment of Li, and lithium defects have not been completely repaired.

Why are negative electrodes more dangerous than positive electrodes?

Compared with positive electrode materials, negative electrode materials are more likely to cause internal short circuits in batteries because of the formation of an SEI layer, dendrites on the ground of the negative electrode and the volume variation of the negative electrode, thus leading to battery failure.
