Why do some car batteries have a sponge cover on the outside?

The main function is to protect the battery. If the connection clips of the two poles of the car battery come into contact with humid air, the water will be oxidized and the two poles of the car battery cannot be connected to electricity. Once connected, the circuit including the computer board will be connected. directly burned. Additionally, the car battery can also leak, so adding a cover to the battery not only protects the battery, but also protects the safety of the car itself.

Its main functions include: when the engine starts or runs at low speed, because the car generator does not generate electricity or the voltage is very low, at this time the electric energy required by the starter, ignition system and electrical equipment of the car are all powered by the battery. When the engine is running normally, the generator powers theelectrical equipment of the car.

Detailed information:

The working principle of the battery: When charging, the external electrical energy is used to regenerate the internal active material, the electrical energy is stored under form of chemical energy and the chemical energy is converted back into electrical energy when it needs to be discharged. Output, such as mobile phone batteries commonly used in life.

It uses a lead-based grid filled with sponge lead (also called a grid) as the negative electrode, and a lead-based grid filled with lead dioxide as the positive electrode, and uses a density of 1 .26 to 1.33 g/mlg/ml. dilute sulfuric acid as an electrolyte.

When the battery discharges, the metallic lead is the negative electrode and an oxidation reaction takes placeoduced to generate lead sulfate; lead dioxide is the positive electrode, and a reduction reaction occurs to generate lead sulfate. When the battery is charged with direct current, elemental lead and lead dioxide are produced at the two poles respectively. Once the power source is removed, it returns to its pre-discharged state, forming a chemical battery.

Is working in a battery factory harmful to my health?

Of course not.

Water after boiling also contains certain minerals, while distilled water is pure H2O. The only elements it contains are oxygen and hydrogen, and there is also some dissolved air. is not clean, if water enters the battery, these minerals will cause abnormal electrolysis, shorten the life of the battery, or even destroy the battery.

Just check if it is a batrie filled with water or without maintenance. When adding water, be careful not to turn the battery upside down and wash it underneath, otherwise the water in the battery will spill out. it is corrosive. When washing the maintenance free battery, make sure there is something on the side for ventilation, just be careful not to get blocked by debris when washing.

Working for a long time in a battery factory will be harmful to your healthBecause when you work here, the environment contains many harmful things, such as mercury . There are many, and the most common component that we usually see is lead, which also floats in the air, is particularly easy to come into contact with, and is also exposed to some electrical radiation. diseases. More attention should be paid to cleaning clothes and washing them frequently. If inhaled, it will be particularlyIt is very difficult to excrete it. We must take good precautions. Only by focusing on prevention can we avoid harm to our body. We can wear protective clothing, such as masks and radiation-resistant clothing, and the room should be ventilated. This can be avoided. Working in a battery factory is very harmful to the body. Inhaling lead is also harmful to the body. the body, because our body often sweats in summer and the sweat expands. At that time, he is more likely to inhale these things, and hair is also a thing to inhale lead. We must wear a hat when we work and change our clothes every day. We can't eat in work clothes. We must wash our hands before eating. Even if we don't eat here, we have to check it out and take a look. for our health. Does the lead it contains exceed the standard? In addition, our nailsalso contain harmful substances. We need to trim our nails regularly to avoid them. Eat more legumes, eat more kelp milk, etc. These foods can all be avoided. We must follow their rules when we work, but we must also take protective measures to avoid causing serious harm to our bodies if lead poisoning also manifests itself. nervous system and immune system, being in this environment for a long time will weaken our immunity and weaken the body. Eating more red dates can help lead to be excreted as quickly as possible. For example, working in a battery factory will also damage your liver and kidneys, so you should pay attention to supplementing your diet.
