Specific analysis of used batteries

1. The composition of the battery: the composition of dry batteries and rechargeable batteries: zinc sheet (iron sheet), carbon rod, mercury, sulfate, copper cap; the battery is mainly composed of lead compounds. Example: The composition of No. 1 used zinc-manganese battery weighs about 70 grams, including 5.2 grams of carbon rods, 7.0 grams of zinc skin, 25 grams of manganese powder, 0.5 grams of copper caps, and 32 grams of others. 2. Types of batteries: The batteries mainly include disposable batteries, secondary batteries and car batteries. Disposable battery packs include button batteries, general zinc-manganese batteries and alkaline batteries. Most disposable batteries contain mercury. The secondary battery mainly refers to the rechargeable battery, which contains the heavy metal cadmium. Waste car batteries contain acid and heavy metal lead. 3. Number of batteries: Digital products such as DC and MP3 are developing at a super fast speed, and they are all using batteries. The usage of batteries is increasing rapidly. If no action is taken, the phenomenon of battery hill will happen sooner or later. Used batteries look inconspicuous, but they are very harmful. If you know the hazards of mercury, cadmium, lead and other metal substances contained in batteries, you will know how bad a waste battery is. Waste dry batteries have a negative impact on the environment (even if it is minor) mainly because they contain mercury. Therefore, developed countries started to control the mercury content in batteries earlier, advocated the development of safe battery products that are conducive to environmental protection, and prohibited the processing of batteries with mercury content greater than 0.025% of the battery weight. In the early 1990s, critical developed countries all achieved mercury-free batteries (with mercury content below 0.0001%).
