by:Vglory      2021-03-03
1. Battery type: batteries mainly include disposable batteries, secondary batteries and car batteries. Disposable battery packs include button batteries, ordinary zinc-manganese dry batteries and alkaline batteries. Disposable batteries contain more mercury. Secondary batteries are mainly rechargeable batteries, which contain heavy metal cadmium. Car batteries contain acid and heavy metal lead. 2. The hazards of waste batteries: Mercury in waste batteries in nature will slowly overflow from the batteries, enter the soil or water, and then enter the human body through crops and destroy the human kidney. Under the use of microorganisms, inorganic mercury can be converted into methylmercury and accumulated in fish. After people eat this fish, methylmercury enters the human brain cells, causing serious damage to the human nervous system, and even death due to mental confusion. The famous Minamata disease in Japan is caused by methylmercury. Cadmium penetrates into contaminated land and water, eventually enters the human body, and damages the liver and kidneys. It can also cause bone weakness and, in severe cases, bone deformation. The acid and heavy metal lead in waste car batteries can cause soil and water pollution, and ultimately harm the human body. 3. Recycling of used batteries: With the popularity and variety of household appliances, the use of batteries has increased dramatically. Used batteries mixed in trash not only pollute the environment, but also waste. my country’s annual battery consumption is 3 billion. Due to the lack of recycling, 740 tons of copper, 16,000 tons of zinc and 97,000 tons of manganese powder are wasted. We should separate used batteries from other garbage and collect them for recycling. Many countries attach great importance to the recycling of used batteries. In Germany, many stores require customers to return second-hand batteries to the store when they buy them. The Japanese patent ledger collects different waste batteries.
