9V rechargeable battery recycling market, 9V rechargeable battery recycling and processing technology
9V rechargeable battery recycling market, 9V rechargeable battery recycling and processing technology. Lithium-ion batteries are generally considered to be environmentally friendly and pollution-free green batteries, but improper recycling of lithium-ion batteries can also cause pollution. Although lithium-ion batteries do not contain toxic heavy metals such as mercury, cadmium, and lead, the positive and negative electrode materials and electrolytes of the battery still have a large impact on the environment and human body.
9V rechargeable battery recycling market
At present, China is the world's largest battery producer and consumer, with annual battery consumption reaching 8 billion. Waste batteries are generally disposed of by landfill, incineration, composting, etc. with domestic waste. The recycling work is massive and urgent. If waste lithium batteries are not systematically processed and recycled, it will seriously waste resources, pollute the environment, and endanger human health.
The huge market demand for lithium-ion batteries will, on the one hand, lead to the emergence of a large number of used batteries in the future. How to deal with these used lithium-ion batteries to reduce their impact on the environment is an urgent problem; on the other hand, in order to cope with the huge market Demand requires manufacturers to produce large quantities of lithium-ion batteries to supply the market.
Wasted lithium-ion batteries contain a lot of metal resources such as cobalt (Co), lithium (Li), nickel (Ni), manganese (Mn), copper (Cu), iron (Fe), etc., including a variety of rare metal resources. Cobalt is a scarce strategic metal in my country, and it is mainly imported to meet the growing demand. Some metal contents in used lithium-ion batteries are higher than those in natural ores, so recycling and processing used batteries has certain economic value amid the increasing shortage of production resources.
9V rechargeable battery recycling and processing technology
9V rechargeable battery recycling methods can be mainly divided into three categories: dry recycling, wet recycling and biological recycling.
1. Dry recycling
Dry recycling refers to the direct recovery of materials or valuable metals without using media such as solutions. Among them, the main methods used are physical separation method and high temperature pyrolysis method.
2. Wet recycling
The wet recycling process is to crush and dissolve the waste batteries, and then use appropriate chemical reagents to selectively separate the metal elements in the leaching solution to produce high-grade cobalt metal or lithium carbonate, etc., for direct recycling. Wet recycling is more suitable for recycling waste lithium batteries with a relatively single chemical composition. Its equipment investment cost is low, and it is suitable for the recycling of small and medium-sized waste lithium batteries. Therefore, this method is currently widely used.
3.Biological recycling
Mishra et al. used inorganic acid and acidophilic Thiobacillus ferrooxidans to leach metals from used lithium-ion batteries, and used S and ferrous ions (Fe2+) to generate H2SO4, Fe3+ and other metabolites in the leaching medium. These metabolites help dissolve metals in spent batteries. The bioleaching method has low cost, high recovery efficiency, less pollution and consumption, less impact on the environment, and the microorganisms can be reused. However, it is difficult to cultivate high-efficiency microbial fungi, long processing cycle, and control of leaching conditions are several major problems required by this method.
4.Joint recycling method
Each waste 9V rechargeable battery recycling process has its own advantages and disadvantages. Currently, there is research on recycling methods that combine and optimize multiple processes to give full play to the advantages of various recycling methods and maximize economic benefits.
Waste 9V rechargeable battery recycling technology
*Bio-smelting method: Using the metabolism of microbial fungi to achieve selective leaching of cobalt, lithium and other elements.
*Direct electrode repair technology: The electrode material is separated by destroying the binder and recycled.
*Synthesis of electrode materials from leachate: The leachate directly participates in chemical reactions to generate lithium cobalt oxide electrode materials.
Summary: The market size of lithium batteries is also growing. The production of more and more 9V rechargeable battery cathode materials means the generation of more and more 9V rechargeable battery waste. Therefore, used lithium-ion batteries need to be recycled to reduce harm to the natural environment and human health. It can be seen that the recycling and reuse of waste lithium batteries has a broad market.
