What is the most widely used method for lithium battery disposal?

The new energy vehicle industry is developing rapidly, and the disposal and recycling of waste lithium batteries has become a research hotspot. The most widely used methods for lithium battery disposal currently include physical recycling and chemical recycling.

Physical recycling method

The physical recycling method of lithium battery disposal refers to the extraction of valuable metals from lithium batteries through physical means such as mechanical crushing, pulverization, screening, magnetic separation, and specific gravity separation with the help of lithium battery recycling equipment.

This method is simple to operate, has a high recovery rate of metals and black powder, stable operation, and is equipped with environmental protection devices to avoid secondary environmental pollution. The physical recycling method is mainly suitable for large-scale waste battery recycling and processing, and can achieve efficient separation through automated production lines.

Chemical recycling method

Chemical recycling methods include wet smelting and high-temperature pyrolysis. It mainly separates the metal elements and organic matter in lithium batteries through chemical reactions.

Wet smelting is to dissolve the metal elements in the battery into the solution through chemical reactions such as acid leaching and alkaline leaching, and then separate them through precipitation, electrolysis and other means. This method has high recovery efficiency and purity, but the operation process is more complicated and requires high equipment and technology.

High-temperature pyrolysis is to calcine the battery at high temperature to burn and decompose the organic matter, and the metal elements exist in the form of oxides or alloys, and then recover them through subsequent reduction, separation and other steps. This method is relatively simple to operate, but the recovery efficiency and purity are low, and a large amount of greenhouse gases such as carbon dioxide will be produced.
