What is the prospect of recycling waste lithium-ion batteries?

Today, most electronic devices such as smartphones, tablets, wearables, and electric vehicles use recyclable lithium-ion batteries. When these lithium batteries are used for two to three years, their functions and efficiency will degrade, and even their lifespan will end. With the rapid development of science and technology, there are many electronic devices, and the market for recycling waste lithium-ion batteries is vast, and resource recycling has many benefits. In the future, with the improvement of the market and policies, the recycling rate of used lithium-ion batteries will be higher.

Batteries account for 36% of the cost of power batteries, and 49% if the gross profit is deducted; the cost of batteries is even higher in consumer batteries. In batteries, the cost of positive electrode materials rich in metal elements such as nickel, cobalt, and manganese accounts for 45%. Through the recycling of waste lithium-ion battery 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 is also more than 70%, with significant economic benefits.

For lithium batteries that can no longer meet the needs of current applications, recycling can effectively play their "surplus value": for lithium cobalt oxide and ternary material lithium batteries used in consumer scenarios, metal elements such as lithium and cobalt and their shells can be recycled ;For power batteries with more complex structures and components, there are two modes: cascade utilization and raw material recovery: (1) Power batteries whose capacity cannot meet the requirements of new energy vehicles but have a long cycle life can be utilized in cascade utilization mode Used in the field of energy storage; (2) For batteries whose cycle life is significantly reduced, renewable resources such as metal oxides, organic electrolytes, and plastic casings can be extracted.

The pretreatment of waste lithium-ion batteries is mainly for waste batteries including: lithium iron phosphate batteries, ternary batteries, nickel-metal hydride batteries and other positive electrode materials. After pretreatment, the materials are more conducive to the leaching of valuable elements in the waste by acid. Waste secondary batteries are composed of metal or plastic shells and battery cores. The total content of organic matter in waste battery cores is 3-6%, and the rest are inorganic compounds of metals; the organic matter is mainly organic binders, electrolytes and non-woven fabrics.

The pretreatment process is mainly to separate the valuable elements in the waste batteries and waste positive electrode materials from the plastics, battery casings and graphite, and the valuable metals are recycled to prepare high-purity compounds, and the plastics, battery casings and graphite are separated.
