Analysis of Heavy Metals in Batteries

When using a wireless mouse, electric toothbrush, electronic watch, remote control, saved a bunch of used batteries. Save also worry, abandon also worry, dilemma, do not know how to deal with.

Since heavy metal cadmium is similar to calcium in bone tissue, cadmium entering the human body can cause bone pain. In addition, zinc manganese dry batteries and button batteries will be plated with a layer of Mercury on the zinc electrode to prevent the battery from producing hydrogen when it is not used. Explosion. That's why there's a recycling campaign for used batteries that started in the 1970s.

Haze has raised everyone's environmental awareness to a very high level. The recycling of used batteries has become deeply rooted in people's hearts. With the continuous development of battery technology, does it still need to "keep the past to this day"? Or to mention the batteries that can be seen by the public, the commonly used batteries are alkaline dry batteries(including but not limited to AA :5, AAA :7, C :2, D :1, and 9 V batteries). It is mostly used for products that require long battery life such as alarms), button batteries(electronic watches, etc.), lead batteries(electric bicycles, cars, etc.), lithium-ion batteries(mobile phones, computers, cameras, etc.) and uninterrupted power supply(UPS). The 12th Five-Year Plan for Comprehensive Prevention and Control of Heavy Metal Pollution states that the major heavy metal pollutants to be prevented and controlled are lead, Mercury, cadmium, Chromium, and arsenic.

Analysis of Heavy Metals in Battery: Lithium-ion Battery etc..

Most people are positive about battery recycling, they think that batteries and pollution are equal. If you tell them that the "Waste Battery Pollution Prevention Technology Policy" issued on October 9, 2003 clearly stipulates that the production of alkaline zinc-manganese batteries with a mercury content greater than 0.0001% will be stopped from January 1, 2005, "in the absence of effective Under the technical and economic conditions of recycling, it is discouraged to concentrate on collecting waste primary batteries that have met the national requirements for low or no mercury. "They will certainly be a little surprised. If you tell them that the Ministry of Environmental Protection and the National Development and Reform Commission issued the regulations on June 6, 2008: the waste nickel-cadmium batteries and mercury oxide batteries produced in the daily life of the family can be managed without hazardous waste but can be mixed with household garbage. They may shake their heads when collecting and landfilling. So why do you have a problem with us to write a battery recycling slogan when I go to school? The battery recycling bins that are everywhere can be displayed only? Can the discarded battery be discarded with the household garbage?

As the main body of the market, we often encounter zinc manganese batteries and alkaline manganese batteries, accounting for about 80 % of the total. Since the Mercury content has been controlled in front of relevant national regulations, it will no longer pollute the environment and will not enter the human body with the food chain. People can treat it as solid waste and treat it with domestic waste.

What kind of batteries do you need to recycle?

First of all, we must resolutely recycle the shoddy batteries produced by small workshops. In addition, lead-acid batteries, which contain heavy metal lead, may increase the body's blood lead concentration in the environment and have an impact on human intelligence; In addition to lead-acid batteries, nickel-cadmium batteries, rechargeable batteries, button batteries used in life(which are not within the mercury-free prohibition of normal dry batteries and still allow the presence of small amounts of mercury) must be effectively recycled in accordance with the instructions of the Environmental Protection Unit.

Maybe you 've heard of a car battery being stolen because a lead battery can sell for more than 100 yuan. The "Cleaner Production Standard Lead Acid Battery Lead Recycling Industry" implemented on January 1, 2010, pointed out that the recovery rate of lead batteries of relevant qualified enterprises must reach more than 95 %, and some advanced equipment companies can even reach 98 %. This is a positive example of battery recovery. However, due to the fact that lead-acid batteries contain about 74 % of lead plates and 20 % of sulfuric acid, the existence of huge benefits has prompted some small workshops to secretly recycle and dismantle lead plates directly, dump waste acid, and the recovery rate is not high. It also leads to pollution of water and soil, and lead ions dissolved in acid enter the environment. This also sounded the alarm for the recycling of used batteries. Recycling is a good thing, and regulation is a major issue. It can not cause pollution while recovering pollutants.

The times are advancing, so should our awareness of environmental protection, and so should our awareness of information. In the face of dry batteries that are already low or free of mercury, we should not be treated as we did when we first advertised them. What we need to do is to reduce the use of batteries containing heavy metal pollution, such as nickel-cadmium batteries, and to continuously develop technical means to phase out batteries containing heavy metals or find alternatives to them; At the same time, we must call on the government to improve the law and build a recycling system for used batteries. The recycling of used batteries can not only reduce environmental pollution but also save a large number of disposable mineral deposits. The recycling of resources and the ecological talents of the environment are the results we most want to see.

If you're not happy next time, try throwing some alkaline dry batteries.
