Turning car battery, the first thought is no doubt lead-acid batteries. Lead-acid batteries through 150 years without failure, in the nickel - cadmium batteries, nickel - hydride batteries, lithium ion batteries, new battery has been launched in several decades, still firmly occupy the majority of market share; annual output of electric bicycles nearly 20 million, most equipped with lead-acid batteries; the world's various locomotive, every car is a piece of lead-acid batteries, they are not.
Lead-acid battery with its mature technology, low cost, high security, etc. favored by many auto manufacturers, power applications in electric cars also have an enormous market share. However, it contains lead and sulfuric acid, it is a garbage dump in one of the most dangerous items, to bring a huge pollution problems. Blacksmith Foundation environmental group, said once: the world's 10 worst pollution problems, one is the error caused by the removal of lead-acid batteries.
Are now able to see the electric bike everywhere, and its batteries to most lead-acid batteries. Electric bicycle battery is a consumable for an average of about 1 year to be replaced. Insiders say: The current lead-acid battery scrap, basically could be restored, after the repair efficiency of up to 80% of new batteries, the second repair efficiency of 50% or more, after three no maintenance after repair value. For any brand of electric vehicle lead-acid batteries, and can still be repaired, through proprietary technology to repair, back into use; of the damage can not be repaired completely lead-acid batteries, recovered by a qualified business lead and zinc processing, refining Secondary Lead. However, this recycling is not always good. There are a lot of recycling waste underground processing plant, they will be recycled lead-acid batteries do not have the conditions stored in the open space or warehouse, there is no qualification process, resulting in a large number of lead waste and waste a lot of emissions.
