Since in 1859, French physicist plante since the invention of lead-acid battery, prolong the service life of the battery is a major topic studied by people, and long-term practice, people use a number of ways to eliminate the battery plate, the following conley of electronic pulses to introduce you to repair the instrument of battery charging and discharging several times to remove sulfide method.

　　For the sulfide cell, the sulfide can be eliminated by several times charging and discharging of the battery with some special pulse restorer. One is high voltage, high current pulse charging, which eliminates sulfuration through negative resistance. This method is fast and effective, but has a greater impact on battery life. Another approach is to use small current frequency up to more than 8 KHZ, the method of using large crystal resonance to dissolve, slowly, the repair methods repair effect is good, but the repair time is long, often in more than 120 hours.

　　The mechanism of this method, from a solid physical point of view, any insulation layer in high enough voltage can be broken through. Once the insulating layer is punctured, it will change from insulation to conduction. Large lead sulfate crystals can be broken by applying a transient high voltage to a sulfate layer with a large conductivity difference and resistance. If the high voltage is short enough and the current is limited, the charge current will not be properly controlled in the case of perforating the vulcanizing layer, which will not lead to battery gas discharges. Battery analysis capacity depends on the size of the voltage of the battery and charging current, if the pulse width is short enough, duty ratio is large enough, can under the condition of guarantee breakdown bulky lead sulfate crystallization, micro charging happened too late to form gas chromatography at the same time, to join in the process of charging the negative pulse, has the function to reduce the battery temperature rise, more can guarantee the breakdown sulfate layer reduces the plate gas evolution, thus realize the pulse elimination of sulfide.

　　In terms of atomic physics, sulfur ions have 5 different energy levels, and the ions in the sub-stable energy levels tend to migrate to stable covalent energy levels. Covalent bond in a stable energy state, sulfur to include eight atoms ring molecules form, the eight atoms annular molecular model is the combination of a stable, difficult to jump and broken, vulcanization phenomenon is the stability level of the battery. To break down the structure of these sulfide layers, a certain amount of energy is provided to the ring molecules, enabling the electrons attached to the outer atoms to be activated to the next high energy band, freeing them from bonds. Each specific energy levels have only resonance frequency, the resonant frequency of high energy can make the transition of the atoms in a state of flux, low energy is not enough to make the atoms from the bondage of groups, such pulse repair instrument in multiple transformation frequency as long as there is a resonance with the sulphur atoms, can make the sulphur atoms into free ions dissolved in the electrolyte, under certain conditions back to active substances, to participate in the electrochemical reaction.

　　Take above 8.33 kHZ to sulfide pulse frequency, pulse of instantaneous voltage generally according to the requirements of the embodied in the product function, the instantaneous voltage of 60 v ~ 300 v, charging pulse width 900 ms, interval of 10 ms, 50 ms, discharge test open-circuit voltage 40 ms, along the steep rise, sulphur removal effect is good. The discharge pulse adopts 3 ohm resistance, and the discharge current is 3~ 4.5a. From the perspective of overcoming polarization, the time of the negative pulse added is very short. Generally, it is about 5% of the time of the positive pulse, and the amplitude is 1.5~3 times of the positive pulse.

　　Pulse wave was used to convert lead sulfate crystals into small, reversible lead sulfate with high electrochemical properties, so that they could participate in the chemical reaction of charge and discharge normally, and the repair rate was about 60%. But the repair time is long, it takes more than dozens of hours, even a week, and the efficiency is low.
