What to do with useless batteries at home

The utilization and treatment process of waste batteries** is roughly as follows:

1.Classify. 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 the remaining black matter is a mixture of manganese dioxide and ammonium chloride as the battery cell.

The graphite rod is washed and dried before being used as an electrode.

2.Zinc granules. The stripped zinc shell is washed and placed in a cast iron pot, heated and melted and kept warm for 2 hours, the upper scum is removed, poured out and cooled, and dripped on the iron plate, and the zinc particles are obtained after solidification.

3.Copper sheets. After flattening the copper cap, wash it with hot water, then add a certain amount of 10% sulfuric acid and boil for 30 minutes to remove the surface oxide layer, remove the copper sheet from washing and drying.

4.**Ammonium chloride. Put the black substance into the tank, add 60oC warm water and stir for 1 hour to dissolve all the ammonium chloride in water, static, filter, and wash the filter residue twice to collect the mother liquor; After vacuum distillation of the mother liquor until there is a white crystal film on the surface, the ammonium chloride crystals are cooled and filtered, and the mother liquor is recycled.

5.Manganese dioxide. The filtered filter residue is washed 3 times, filtered, and the filter cake is placed in a pot to 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 dry the filter cake at 100-110oC to obtain black manganese dioxide.

What would you do with a used battery that has no power?

1. Method 1, take out the battery, clamp the body of the battery with pliers, pay attention to the positive and negative poles of the battery with pliers, in the process of clamping, the inside of the battery is squeezed, so that the chemicals inside release a part of the electric energy.

2. Method 2: Take out a dry towel and rub the positive pole of the battery, that is, the protruding pole, on the towel, and the friction can also produce a part of the electrical energy, so as to stimulate a part of the internal electrical energy, so that the battery can continue to be used.

The working principle of the battery is: in a chemical battery, the direct conversion of chemical energy into electrical energy is the result of spontaneous oxidation, reduction and other chemical reactions inside the battery, which are carried out on two electrodes. The anode active material consists of a reducing agent with a negative potential and stable in the electrolyte, such as reactive metals such as zinc, cadmium, lead, and hydrogen or hydrocarbons.

The cathode active material is composed of oxidants that are potentially corrected and stabilized in the electrolyte, such as metal oxides such as manganese dioxide, lead dioxide, nickel oxide, oxygen or air, halogens and their salts, oxygenated acids and their salts, etc. Electrolytes are materials with good ionic conductivity, such as aqueous solutions of acids, alkalis, salts, organic or inorganic non-aqueous solutions, molten salts or solid electrolytes.

When the external circuit is disconnected, although there is a potential difference (open-circuit voltage) between the two poles, there is no current, and the chemical energy stored in the battery is not converted into electrical energy. When the outer circuit is closed, a current flows through the outer circuit due to the potential difference between the two electrodes.

1. Put the battery close to the positive and negative electrodes, bite them with your teeth, they are usually very soft, of course, there are also very hard batteries, this method is not easy to get. And be careful when operating, do not cause them to leak, because they are still very polluted and have a lot of toxins. So this method has a certain danger.

2. Put the positive electrode on the pants and grind it, so that the friction will actually produce a part of the power, but this power is to stimulate the power inside the battery, so that they can be released again. This method allows them to recover for a short time, but not for long.

A battery is a device that converts chemical energy into electrical energy in a cup, trough or other container or composite container that contains an electrolyte solution and metal electrodes to generate an electric current. It has a positive electrode and a negative electrode. With the advancement of technology, batteries generally refer to small devices that can generate electrical energy.

Such as solar cells. The performance parameters of the battery mainly include electromotive force, capacity, specific energy and resistance. Using the battery as energy**, you can get a current with stable voltage, stable current, stable power supply for a long time, and little influence from the outside world.

What to do if the battery is out of power, teach you a trick to use waste batteries.

Don't lose the battery when it runs out, teach you a trick, and it will be charged immediately.

Don't throw away the battery when it's out of power, you can restore it with one move.

Hello, dear, very happy for your question, how to deal with the battery after there is no power, help you find out, the general treatment method after the battery is not power: 1 If the battery has no excess electricity, we need to remove the battery 2 Then squeeze the surface of the battery hard, so that part of the chemical reaction inside the battery will occur, so as to produce part of the power. 3. At this time, we only need to put it back into use, and we will find that the battery has a little power.

4. At this time, there will be electricity, and we can use it normally for a while. Hope mine can help you. Wishing you good health and a happy mood!

Hello, dear, the battery is generally disposed of by hazardous waste after there is no electricity. Kiss. How to run out of battery:

1. After the car battery is lost, it should be charged immediately with a charger, if it cannot be charged with an ordinary charger, it is necessary to use the high-resistance repair of the repair instrument to increase the voltage to more than 10V before rushing in. 2. If your battery voltage is lower than 9V, and it can't be improved after charging and repairing, you must replace the battery with a new one. 3. The ordinary lead-acid battery can be used if it is recharged, and the maintenance-free lead-acid battery can be scrapped directly if the power loss is serious, and it cannot be charged twice.

4. If you feel that the charger is not charged or the starter is weak, and the headlights are obviously dimmed, you need to remove the battery and charge it with the charger for 12-24 hours, if it is not possible and the mileage has reached more than 50,000km, and the generator is not faulty, you need to consider replacing the battery.

Depending on the type of battery, the place where it can be thrown is also different.

Like the zinc-manganese batteries used in life for remote controls, water heaters, etc., they are disposable and non-rechargeable batteries. The mercury in this dry cell battery is not exceeded, so it can be disposed of as other garbage. However, lithium batteries such as button batteries, mobile phone batteries, and power banks are still harmful and need to be disposed of as hazardous waste.

It is understood that according to the relevant national regulations, the production and sale of mercury oxide batteries are currently prohibited, and the production and sale of zinc-manganese and alkaline zinc-manganese batteries with mercury content greater than the quality of the battery are prohibited; On January 1, 2005, the production of alkaline zinc-manganese batteries with greater mercury content was stopped. As a result, qualified primary batteries currently produced and sold are not included in hazardous waste management due to relatively small environmental risks.

If the public still puts the dry battery in the garbage can of hazardous waste according to the traditional thinking, the sanitation workers will also separate it again when they are sorted and transported in the follow-up, or follow the hazardous waste to be collected and transported to the temporary storage point, but when it is finally sent to the treatment plant, this part of the dry battery mixed with the hazardous waste will also be rejected. Eventually, the dry batteries are disposed of as other waste and are landfilled or incinerated like other waste.

It should be concealed that the laptop cannot be charged due to the failure of the power adapter, and the solution is as follows.
