What are the important types of batteries? Batteries are mainly divided into two categories, primary batteries and secondary batteries. Primary batteries mainly include ordinary zinc-manganese batteries, alkaline zinc-manganese batteries, and mercury oxide batteries. Among them, waste mercury oxide batteries are hazardous wastes. The various batteries used in other people's daily lives are not managed as hazardous waste after being discarded. Secondary batteries are divided into two categories: rechargeable dry batteries and wet batteries. Rechargeable dry batteries mainly include nickel-cadmium batteries, nickel-hydrogen batteries, lithium batteries, etc., and wet-type batteries are mainly lead-acid batteries. Among them, nickel-cadmium batteries and lead-acid batteries (such as batteries used in automobiles and other motor vehicles) contain a large amount of heavy metals such as lead and cadmium, which are classified as hazardous waste. Other types are not managed as hazardous waste. Therefore, the three types of batteries that should be managed as hazardous waste after being discarded are mercury oxide batteries, nickel-cadmium batteries and lead-acid batteries. How to dispose of the batteries used in our lives, such as remote controls, electronic toys, and alarm clocks? The ordinary disposable dry batteries that we use every day are basically alkaline mercury-free batteries, which can be disposed of with domestic waste. How to dispose of mobile phone batteries, power banks, and used batteries for electric vehicles? Mobile phone batteries and power banks are lithium batteries with relatively low environmental risks. They are not included in the management of hazardous waste and can be recycled. However, lead-acid batteries are often used in electric bicycles, which are hazardous wastes that are harmful to the environment and must be specifically recycled and disposed of .
