What do you know about old batteries?

An old battery is a battery that has been used by people, reached the end of its useful life, ran out of power, and can no longer be used. Used batteries contain a lot of harmful substances that can cause harm to the environment if not disposed of properly. Therefore, it is very important to dispose of used batteries correctly.

Some common used batteries include disposable batteries, rechargeable batteries, and car batteries. Waste batteries contain heavy metals such as mercury, cadmium, and lead, which are very harmful to the environment and human health. If not properly handled, these metals can leach into water and soil, causing damage to ecosystems.

For the disposal of waste batteries, there are generally three methods: sorting garbage, industrial treatment and utilization. In the classified garbage, the waste batteries can be put into the special battery trash can and wait for the relevant departments to dispose of it.

Industrial treatment refers to the use of batteries in a high-temperature environment, through heat treatment to non-toxic batteries, and the metal components in them. Utilization refers to the reuse of useful substances in waste batteries to reduce the waste of resources.

When dealing with waste batteries, we should pay attention to the following points: First, try to use mercury-free batteries to reduce pollution to the environment. Secondly, waste batteries should not be modified or discarded at will, so as not to cause harm to the environment.

Finally, the placement of waste batteries should be done safely, and should not be placed next to flammable and explosive materials to avoid danger.

In short, it is very important to dispose of waste batteries correctly, not only to reduce pollution to the environment, but also to save resources. We should take active measures to properly dispose of used batteries and protect the environment and human health.

1.The Dangers of Used Batteries One button battery can pollute 600,000 liters of water, which is equivalent to the amount of water a person drinks in a lifetime. A battery rotting in the ground can make one square meter of land useless.

Summary. You can smash the waste battery, peel off the zinc shell and the bottom iron of the battery, take out the copper cap and graphite rod, and for the remaining black matter, it is a mixture of manganese dioxide and ammonium chloride as the battery cell. The ink rods are washed and dried and can be reused as electrodes.

2. After washing the stripped zinc shell, put it in a cast iron pot, heat it and keep it warm for 2 hours, remove a layer of scum on it, pour it out for cooling, and then drip it on the iron plate, and so on until it solidifies, you can get zinc particles.

3. The copper cap can be flattened and then washed with hot water, and then a certain amount of 10% sulfuric acid is added and boiled for 30 minutes to remove the oxide layer on the surface, remove and wash, and dry to obtain copper sheets.

4. Put the black substance into the tank, and then add warm water at 60 degrees Celsius and stir for an hour, so that all the ammonium chloride will be dissolved in water, and the filter residue will be stilled, filtered, and washed with water for 2 times to collect the mother liquor.

5. Wash the filtered filter residue 3 times, filter, put the filter cake into the pot and evaporate to remove a little carbon and other organic matter, and then put it into the water and stir it fully for 30 minutes, filter, and then put the filtered cake at 100-110

Small seconds for families! We can use dry batteries to deal with the static electricity on our sweaters, in the fall, when we take off our sweaters, there is always a lot of static electricity on it, we can use batteries to solve it, we use the battery positive electrode to rub on our sweaters, so that we can deal with the static electricity on it, and when we wear it, there will be no static electricity on it! It works very well.

Sharpen scissors After the scissors at home are used for a long time, they will become dull and not sharp, in fact, there is a better way at this time, that is, we use scissors to cut the waste battery, cut a few more times;

Old batteries are very important because batteries contain many substances that are harmful to the environment and the health of the wild segment. Chemicals in batteries, such as lead, mercury, cadmium, zinc, manganese, etc., can cause serious effects on the environment and human health if disposed of haphazardly.

If batteries are properly disposed of and**, many of these materials can be reworked to make new batteries and other products. Old locust batteries can reduce the demand for natural resources and reduce production costs, while also reducing dirt and waste generation.

In addition, some countries and regions have implemented battery ** policies and regulations that require manufacturers and consumers to participate in battery ** programs. These programs not only benefit the environment and human health, but also contribute to a circular economy, improve resource efficiency, and promote sustainable development.

Old batteries pollute the environment. Especially high-voltage batteries. It will cause high-voltage electric shock accidents to the human body. Causing harm to the human body. So. Old batteries to**.

First of all, waste batteries are hazardous waste in garbage classification. Hazardous waste needs to be treated safely and irreversibly polluted to groundwater if not thrown directly into the natural environment.

Prevent environmental pollution. The components of dry batteries and rechargeable batteries that we commonly use are mainly composed of zinc scale, iron scale, carbon rod, mercury, sulfide, copper cap, etc.

How to use waste batteries abroad.

Japan's Hokkaido Nomura Kosan Company purchases 130,000 tons of waste batteries from the country every year, accounting for 20 of the country's waste batteries, and the collection method is 93 collected through non-governmental environmental protection organizations, 7 collected through various manufacturers. In the past, mercury was mainly used in the first battery, but now the domestic battery does not contain mercury, and the iron shell of the main battery and the "black" raw material in it, and the development and manufacture of secondary products, such as one of the products can be used to produce picture tubes for televisions.

Germany requires consumers to send used dry batteries, button batteries and other types of batteries to stores or waste stations, and stores and waste stations must unconditionally accept used batteries and transfer them to manufacturers for disposal. Waste stations and manufacturers generally only ** batteries containing toxic chemicals such as cadmium and mercury, while 90% of the ordinary zinc-carbon batteries and aluminum-magnesium batteries are landfilled or incinerated as household waste.

The United States is a country with the most detailed legislation on the environmental management of waste batteries, not only establishing a complete waste battery system, but also establishing a number of waste battery treatment plants, and at the same time unremittingly carrying out publicity and education to the public, so that the public consciously supports and cooperates with the work of waste batteries.

Do you mean electric vehicle batteries, if it is an electric vehicle battery, you can send it to a battery store such as Tianneng battery, either sell it directly, or you can trade in the old and then post some money, because the electric vehicle battery is a lead-acid battery, and she has to waste the battery**The value of the metals and elements that can be used is relatively high.

Summary. Hello, dear. What to do with used waste batteries is as follows:

1 7 Centralized treatment: Concentrate the waste batteries in the trash can of the waste battery, and wait for the sanitation workers to come and dispose of it. 2 7 Incineration:

We must choose the right place, and we should try to choose a mountain or other remote place far away from the human living area to burn, so as to minimize the harm to human beings. 3 7 Landfill: In the place where the state stipulates that the waste battery can be landfilled, the battery is first wrapped in a plastic bag or carton, and then a large pit is dug to bury the waste battery in the pit.

3 7 Landfill: In the place where the state stipulates that the waste battery can be landfilled, the battery is first wrapped in a plastic bag or carton, and then a large pit is dug to bury the waste battery in the pit.

4 7 Heat treatment: There are two factories in Switzerland that specialize in processing and using old batteries, and the method is to grind the old batteries and send them to the furnace for heating, at which time the volatile mercury can be extracted, and when the temperature is higher, zinc also evaporates, which is also a precious metal. Iron and manganese are fused to form an iron-manganese alloy for steelmaking.

5 7 Wet treatment: Another company built a "wet treatment" plant in the suburbs, where all kinds of batteries are dissolved in sulfuric acid except for lead-acid batteries, and then various metals are extracted from the solution with the help of ionic resin, and the raw materials obtained in this way are purer than heat treatment methods, so they are sold at a higher price in the market, and 95% of the various substances contained in the battery can be extracted. Sorting can be eliminated (because sorting is a manual operation, which increases costs).

With an annual processing capacity of up to 7,500 tons, the plant is slightly more expensive than the landfill method, but valuable raw materials are not discarded and do not pollute the environment. 6 7 vacuum heat treatment method: the vacuum heat treatment method developed by a German company is cheaper, but this first needs to sort out the nickel-cadmium battery in the waste battery, the waste battery is heated in a vacuum, in which the mercury evaporates rapidly, it can be **, and then the remaining raw materials are ground up, and the metal iron is extracted with magnets, and then nickel and manganese are extracted from the remaining powder.
