The recycling of waste batteries should "get forgive and forget."

How old battery recycling
Used batteries have been collected, to prevent an act of their entry into the ecosystem, causing harm to the environment. A lot of heavy metals in an electrolyte solution and waste acid, waste alkali, such as the used batteries contain. If thrown away, corruption battery will destroy our water, crops and land erosion of our survival, our environment will be facing a huge threat. So we need to be discarded after use battery recycling, one can prevent the pollution of the environment, and secondly, the composition of which can be useful for reuse, conserve resources. "Pollution of water is equivalent to a mobile phone battery three standard swimming pool," the slogan used battery recycling activities as propaganda for a long time, the last decade, almost became the

environmental advocacy menstrual stickers, such as here. However, the authenticity of this slogan have always been questioned, even tucao as "pseudo-environmental knowledge," Why do you say that? Rumor mill editing a long article to analyze all kinds of scientific problems "waste battery recycling" campaign behind it.
Battery classification knowledge

Recycling of used batteries lasted two decades of advocacy and action, the effects involving more than 80% of the population, almost all primary and secondary schools and various colleges and universities are involved in it. However, there are still a lot of people all the batteries are vaguely confused, this is not science. To understand the waste battery recycling, classification is the first thing to learn.

Battery life common are the following:

1, lithium batteries, can be found at the cell surface lithium chemical element symbol Li;

2, alkaline batteries, also known as manganese batteries, the battery surface may have its English name: Alkaline battery, some will be written on mercury-free alkaline batteries;

3, nickel-cadmium or nickel-metal hydride batteries, the batteries were identified as Ni-Cd or Ni-H, the former contains a lot of heavy metal cadmium, which contain cadmium, need to pay attention to distinguish;

4, lead-acid batteries, which often can be found in electric vehicles, the English called lead battery.

The greatest impact on the environment, there are five heavy metals, namely arsenic, lead, cadmium, chromium and mercury. In the battery inside, which mainly contains three kinds, they are lead-acid battery lead, cadmium nickel-cadmium batteries, as well as an additive in alkaline manganese batteries exist mercury. In addition several common batteries, such as lithium batteries, nickel hydrogen batteries, toxic heavy metal content which is almost negligible. "Pollution intensity of a used cell phone battery is 100 times that of ordinary alkaline batteries can be seriously polluted 60,000 liters of water, equivalent to three standard swimming pool", if this sentence refers to is the most common cell phone lithium or NiMH batteries battery, this pollution is clearly nonsense description.

The recycling of waste batteries should "get forgive and forget."

Features heavy metals containing each of the three batteries.

Lead-acid battery feature is to make money, an old lead-acid batteries can sell more than 100 pieces, casually discarded phenomenon rarely, recycling is doing the best. There are of course a big problem after it recovered after this time being the following table.

Nickel-cadmium batteries are characterized by no future, because it contains large amounts of heavy metals cadmium, nickel-metal hydride or lithium batteries have been replaced in many areas batteries, will be phased out from the market.

Alkaline batteries are characterized by a small number of great harm. Zinc-manganese batteries containing mercury drop in the amount of waste battery recycling movement twenty years obtained most delightful results. With the development of technology, low mercury or mercury-free zinc-manganese batteries are becoming the main market, the mercury reduction by means of reducing its environmental hazards. "Waste Battery pollution control technology policy," China has promulgated regulations: Since January 1, 2005 to stop the production of mercury-containing greater than 0.0001% of alkaline manganese batteries.
