What are the methods for sorting and collecting used batteries?

One is a variety of disposable dry batteries with different capacities such as No. 1, No. 5 and No. 7 used in flashlights and remote controls. Dry battery is a chemical battery that uses paste electrolyte to generate direct current. Since January 1, 2005, my country has stopped processing and selling alkaline batteries with a mercury content of more than 0.0001%. At present, the disposable dry batteries used in households adopt mercury-free and low-mercury technologies. The environmental impact has become very slight. The national 'Waste Battery Pollution Prevention and Control Technology Policy' clearly stipulates that in the absence of effective recycling technology, centralized recycling of waste disposable batteries that have reached the national low mercury or mercury-free requirements is not encouraged. Therefore, such used batteries should be discharged with household garbage. The second is rechargeable batteries and button batteries used in children's toys and electronic watches. The button cell is made of stainless steel and serves as the positive electrode. The negative electrode is a stainless steel circular cover. There is a sealing ring between the positive electrode and the negative electrode for insulation. The sealing ring is made of nylon. The sealing ring is not only used for insulation, but also prevents electrolysis. Liquid leaks. Such used batteries are hazardous wastes of social origin. According to the “National Directory of Hazardous Wastes” revised in 2008, such hazardous wastes of social origin in household daily life may not be managed as hazardous wastes, that is, they may be discharged with household garbage. However, the national 'Waste Battery Pollution Prevention and Control Technology Policy' also stipulates that manufacturers and importers of rechargeable batteries and button batteries, as well as manufacturers of rechargeable batteries or button battery products, shall bear the responsibility for recycling waste rechargeable batteries and waste button batteries. Responsibility, set up a sorting and recycling facility for waste batteries at the sales office to collect them and send them to a factory (facility) with corresponding qualifications for resource utilization or harmless treatment. Therefore, in the process of using such batteries, residents can send used rechargeable batteries and waste button batteries to the corresponding waste battery recycling facilities of the sales store for the convenience of the sellers to recycle. The third is cell phone batteries used in cell phones. Cell phone batteries generally use lithium-ion batteries and nickel-metal hydride batteries. According to incomplete statistics, the number of mobile phones in my country currently exceeds 1.3 billion, almost reaching the level of an average manpower. The environmental pollution of used mobile phone batteries cannot be ignored. Discarded mobile phones and batteries contain heavy metals such as gold, mercury, lead, and cadmium. If they are directly discarded or landfilled, heavy metals will directly pollute the soil and groundwater; while simple incineration, the gas generated will also pollute the air and cause people to be poisoned. At present, used mobile phones have been included in the National 'Waste Electrical and Electronic Products Disposal Directory' (2014 edition). The used mobile phone batteries can be handed over to the waste electrical and electronic product dismantling company along with the waste mobile phones to achieve harmless disposal or resource utilization through disassembly. . At present, Dalian Dafengye Metal Co., Ltd., located in the National Eco-industrial Demonstration Park of Dazheng Town, Zhuanghe, has the corresponding qualifications. The company can also receive state subsidies for dismantling discarded mobile phones. Fourth, lead-acid batteries used in UPS uninterrupted power supplies such as elevators and banks and used as batteries for motor vehicles. The centralized collection of waste lead-acid batteries needs to apply for a hazardous waste transfer form before they can be transferred to a company with hazardous waste management qualifications. The fifth is the power lithium battery for new energy electric vehicles. Electric vehicle processing companies, battery processing companies, battery cascade utilization companies, and end-of-life vehicle recycling and dismantling companies bear their respective recycling responsibilities, and encourage companies to take deposits, repurchase, and trade-in measures for power batteries to increase consumers’ return of waste The enthusiasm of the power battery.
