Commonly used equipment: Nickel-cadmium batteries are cheaper versions of rechargeable alkaline batteries. They can be recharged hundreds of times to avoid recycling of disposable batteries, which are usually interchangeable with alkaline batteries. Another type of battery without cadmium is a nickel-hydrogen battery, and many rechargeable batteries are often nickel-hydrogen batteries.
Recycling method: There is a small common sense about nickel-cadmium batteries, that is, part of the price includes the cost of recycling. Because they contain toxic cadmium metals, these batteries are hazardous waste and should not be disposed of in landfills.
In 1994, the rechargeable battery industry formed a rechargeable battery recycling company that provided recycling points for nickel-cadmium and nickel-hydrogen batteries in thousands of retail stores and public places.
Recovery results: These two batteries need to be heated during recovery to separate high temperature metallic nickel and iron from low temperature metal zinc and cadmium; some metals will solidify after melting, while others are reprocessed as metal oxides. . These metals have a certain value.
