What are the curing and cleaning methods of Panasonic battery?

Panasonic battery has a very important application in our life. Do you know the curing and cleaning methods of Panasonic battery? Here is a detailed introduction:
1、 Battery overview
Lead acid battery technology has not changed in 100 years. Although chemical and structural improvements have been made, there is a common element that causes battery problems. The reason for this problem is that sulfate accumulation on the plate causes failure. The most effective way to deal with these problems is to apply pulse technology.
Pulse technology helps to eliminate these battery problems. It can adhere to high reactive substances, make the battery internal balance, easy to bear external charging. In this way, various related costs caused by battery replacement are saved.
2、 Technical introduction
Experts predict that the lead-acid battery will continue to be the first in the battery power supply field until the next century. However, it is worth noting that most batteries can not meet the needs of today's advanced technology vehicles. Generally speaking, the response data of lead-acid battery can last for 8-10 years or longer, but in fact, it can't be done. Today's average battery life is 6-48 months. Only 30% of the batteries can be used for 48 months. Most batteries age and fail early. A series of problems affecting battery life are caused by the accumulation of sulfate, and the most effective way to deal with these problems is pulse technology.
As early as 1989, there was the first patent, which applied pulse technology to improve the applicability of batteries and extend the battery life. Its working principle: make the battery keep high active material response, make the battery internal balance, easy to bear charging. This technology can provide large discharge capacity, bear charging fast, and can be used for durability. (in other words, extend battery life)
Now let's understand how pulse technology benefits batteries and how it works. First of all, let's review the working principle of the battery: according to the 11th edition of the Handbook of the international battery Council: "the battery belongs to the category of electrochemical principle design, and the electric energy generated by the battery is transformed from the stored chemical energy. The battery is required for vehicles and power mechanical equipment. Its three main functions are:
(1) Supply power to the ignition system to start the engine.
(2) Supply power to electrical equipment outside the generator.
(3) , it can stabilize the voltage of the electrical system, make the output smooth and reduce the sudden high voltage of the electrical system. "
The battery consists of two different materials (lead and lead dioxide), which react in sulfuric acid to generate voltage. During the discharge process, the active data on the positive lead plate and the sulfuric acid radical of the electrolyte generate PbSO4. At the same time, the activity data of the negative plate and the sulfuric acid of the electrolyte also form PbSO4. Therefore, the results of the discharge make the positive and negative plates cover the lead sulfate (PbSO4). The battery is restored by charging it in the opposite direction.
In the charging process, the chemical reaction state is the reverse reaction of the discharge. At this time, the synthesis of lead sulfate (PbSO4) on the positive and negative plates becomes the original state, that is, lead and sulfate, hydrate to "H" and "O" atoms, and when the separated sulfate and "H" are separated, they are recovered to sulfuric acid electrolyte.
From the above, the fundamental principle of Panasonic battery is the energy formed by the chemical reaction process of sulfuric acid and lead to stop ion exchange. In the process of energy exchange, the reaction product lead sulfate is "temporary" on the plate. However, it should be noted that during the charge recovery process, the lead sulfate on the plate does not dissolve completely and pile up on the plate. This deposit is the remnant of the electrochemical response, occupying the position of the plate. That is to say, the effective response information of the plate is decreasing from time to time, which is the main reason for battery failure. (lead sulfate causes battery failure, which is simply called plate salinization)
Plate salinization: most battery failures are due to the build-up of lead sulfate. When the energy of lead sulfate molecules is greater than a limit low value, they dissolve from the plate and return to the liquid state. Then they can withstand recharging. But in practice, there is always a part of sulfate that can not be returned to the electrolyte, but attached to the plate, and finally formed an insoluble crystal. The sulfate crystal is composed of the following: the central energy of these single sulfate molecules which can not participate in the reaction is in a very low state, and it gradually absorbs other sulfate molecules with very low energy. When these molecules pile up and separate tightly, they form a crystal. This kind of crystal can't dissolve into the electrolyte effectively. The existence of these crystals occupied the position of the plate, making the plate lose the ability of charge and discharge. Therefore, the point or part of the plate being covered is equivalent to the dead point.
According to page 58 of BCI manual, "the essence of battery is chemical equipment, and its charging characteristics are often changed by the chemical change of battery itself. For example, sulfate should be a normal chemical reaction product, but in an abnormal state, it becomes superfluous substance and becomes the main problem affecting the chemical reaction. These superfluous sulfates accumulate on the plate from time to time and are neglected for a long time. In addition, if the storage time of the new battery is too long, it will also present this state. When the battery is seriously salinized, it can't bear the fast and full power supply from the generator. Similarly, it can't be a satisfactory discharge. With the increase of salinization, the battery eventually fails because it can't bear charging and discharging. " It is said on page 56: "the charging voltage is determined by the temperature and electrolyte concentration, and the area of the electrolyte contact plate
