Recovery of common sense
In view of the widespread use in recent years of people the production and life of the battery, the new green battery in use or under development. Now widely used nickel metal hydride batteries, lithium-ion batteries, is the promotion of mercury-free alkaline manganese dioxide primary batteries and rechargeable batteries are used, is developing and lithium batteries or lithium ion batteries, fuel cells, electrochemical storage of super capacitor can belong to waste battery category.
Battery materials, batteries are sealed within the housing, do not affect the environment. But batteries after long term mechanical wear and corrosion, material, such as heavy metals and acid leaks into the soil or water, causing waste battery environmental pollution. Treatment 。 Waste battery recycling, treatment and disposal, States have yet to develop specific policies and regulations.
However, through a proven long life, the following is valid: place the charging of battery recycling bins, hand collected on a regular basis, classification battery (battery, button battery), city warehouse storage class focus and then sent to a number of locations on the outskirts of, placed in sealed battery type battery-recycling technologies, introduction of maturity. Waste batteries, until the container. Batteries contain many important chemicals, such as copper, zinc, manganese dioxide, ammonium chloride, handled well, you can get a lot of useful material. For example: collecting copper CAP, pure ammonium chloride (NH4CI), purification of manganese dioxide and zinc extraction.
