Four development courses of lead-acid batteries

Four development courses of lead-acid batteries

Ordinary lead-acid battery Lead-acid batteries produced in the 1950s are now called ordinary batteries, and users at that time had to have an “initial charging” process link when using the product. After the electrolyte is injected into the battery, the battery heats up. After the temperature of the electrolyte drops, the first charge is performed, […]

Influence of lead-acid battery-sulfuric acid electrolyte on battery discharge performance

Influence of lead-acid battery-sulfuric acid electrolyte on battery discharge performance

Influence on battery internal resistance In lead-acid batteries, the resistivity of the electrolyte is thousands of times greater than the resistivity of various substances on the positive and negative plates. Therefore, under normal circumstances, the internal resistance of a fully charged battery is largely determined by the electrolyte. The internal resistance of a discharged battery

How much do you know about other auxiliary knowledge about battery charging?

Battery-Auxiliary knowledge you need to know about battery charging

Rational use of additives From the chemical reaction equation, it can be seen that PbO2, Pb and H2SO4 are the necessary substances to really participate in the reaction in the battery charge and discharge reaction. Now there are all kinds of additives in the market, which only play an auxiliary role. Through the role of

What is the effect of temperature on battery performance and the startup of dry charged battery

Lead-acid batteries – the effect of temperature on battery performance and the use of dry-charged batteries

Effect of temperature on battery performance It can be seen from the reaction equation that PbO2 is on the positive plate and Pb is on the negative plate. The conductivity of these two substances changes very little with temperature. Therefore, it can be said that the temperature effect of battery discharge performance is caused by

What is the "reverse polarity" of a battery?

What is the “reverse polarity” of a battery?

The chemical reaction equation of a lead-acid battery says: PbO2+2H2SO4+Pb=PbSO4+2H2O+PbSO4 It can be seen from the reaction equation that PbSO4 is generated on the positive and negative plates after the discharge is completed. At this time, theoretically speaking, if the same substance is immersed in the electrolyte, there is naturally no potential difference, and there

What are the limiting factors for the charge-discharge reaction?

What are the limiting factors for the charge-discharge reaction?

The charge-discharge reaction of the electrode proceeds only at the interface in contact with the electrolyte. As can be seen from Figure 1, the reaction of the positive electrode must be PbO2 and SO42- contact, 0 and H contact, the reaction of the negative electrode must also be Pb and SO42- contact, no contact can

What is the desulfurization and capacity recovery technology of lead-acid batteries?

What is the desulfurization and capacity recovery technology of lead-acid batteries?

At (+) electrode:PbO2 + 3H++ HSO4– + 2e –→PbSO4 + 2H2OAt (-) electrode:Pb + HSO4–→PbSO4 + H+ + 2e–Overall reaction formula:PbO2 + Pb + 2H2SO4 → 2PbSO4 + 2H2O It can be seen from the reaction equation that PbSO4 is formed on the positive and negative plates after discharge, and the reaction can proceed to
