What is lead-acid battery electrode material made from?

Storage battery is divided into negative and positive electrode. Commonly, the two electrodes of battery are pasted plates. On the grid frame made of lead alloy casting, lead sulfate cream compounded of lead powder and vitriol, etc. become a plate after dehydration. At this time both electrodes are a mixture, lead, lead sulfate, sulfuric acid, also is called green plate. After repeated across the electrodes of direct current, charge and discharge "into" later, the anode into a red brown, main component is a lead dioxide, cathode lead into caseous pile shape. This is he is negative electrode materials. After discharge, the main material of is negative components, respectively, and the generation of dilute sulphuric acid reaction in the battery lead sulfate. At this moment is the cathode have become the primary components of lead sulfate. Charging current role because it is over, until the end of charging, is negative and reductive into lead dioxide, and wool lead respectively. Is that clear? This is the working principle of lead-acid batteries. If you are the cathode active material, participate in the reaction of effective composition is less and less, the performance of the battery will become worse and worse. To less than 80% of the rated capacity, the useful life of the battery.

Lead-acid battery (VRLA), is a kind of electrode is mainly composed of lead and its oxide, battery electrolyte is sulfuric acid solution. Lead-acid battery discharge condition, the positive main ingredients for lead dioxide, negative main ingredients to lead; Charging status, the main components are all lead sulfate is negative.

A single case of lead-acid battery nominal voltage is 2.0 V, can discharge to 1.5 V, can charge to 2.4 V. In the application, often together with six single lead-acid batteries of nominal is 12 v lead-acid battery, and 24 v, 36 v, 48 v, etc.

French plante invention lead-acid batteries in 1859, has experienced nearly 150 years development course, lead-acid battery in terms of theoretical research, the species and varieties of products, product electrical performance, etc. got great progress, both in transportation, communications, electric power, military and in the field of navigation,special economies, lead-acid batteries have played an indispensable role.

Lead-acid battery structure

According to the structure and USES the difference between lead-acid batteries, battery roughly divided into four categories: 1, starting with lead-acid battery;2, power use lead-acid batteries;3, a fixed valve control type sealed lead acid battery;4, other classes, including small valve-control sealed lead-acid battery, miner's lamp with lead-acid battery, etc.

A single case of lead-acid battery nominal voltage is 2.0 V, can discharge to 1.5 V, can charge to 2.4 V. In the application, often together with six single lead-acid batteries of nominal is 12 v lead-acid battery. There are 24 v, 36 v, 48 v, etc.

The main features

Security seal

Lead-acid battery

In normal operation, the electrolyte will not be leaking from the battery terminal or shell. There is no free acid

Special liquid partition keep acid, no free acid inside the battery, so the battery can be placed in any position.

Frustrated system

After the battery internal pressure is beyond normal levels, VRLA batteries will blow off gas and automatically seals, guarantee no excess gas in the battery.

Simple maintenance

Due to the complex system makes the gas into water, in the process of using VRLA batteries don't need to add water.

The service life is long

Adopted the structure of lead calcium alloy corrosion resistant tailgate VRLA battery can be used floating 10-15 years.

Stable quality and high reliability

The use of advanced production technology and strict quality control system, the VRLA battery quality is stable, reliable in performance. Voltage, capacity and seal online 100% inspection.

Safety certification

All VRLA batteries have passed UL safety certification.

Product structure

VRLA batteries is designed like this: in the battery, part of electrolyte is absorbed in the plate and baffle plate to increase the cathode oxygen ability, and prevent the electrolyte loss, so that a battery can be sealed.
