Lead-acid battery features:
(1) removable performance, easy to use.
(2) voltage and capacity can be adjusted within a considerable range, changes (through the string parallel connection and hybrid relationship to achieve).
(3) can be made according to the needs of any shape.
(4) after a special design and processing, Standard Lead Acid Battery can be used for high pressure, weightlessness, high temperature, low temperature, shock, strong impact and other special environment.
(5) product prices relative to other chemical power cheaper.
The lead-acid battery was invented in 1859 by French physicist Prandt. At that time, he used two lead plates for the electrode, placed in dilute sulfuric acid for electrolysis, Standard Lead Acid Battery the electrolysis of the current direction of continuous transformation, the results of the lead plate storage capacity continues to increase, forming a battery. By 1881, Ford invented the paste plate, he used lead oxide (lead oxide or lead dioxide) and dilute sulfuric acid mixed into lead paste, added on the uneven plate, placed in dilute sulfuric acid In the electrolysis of the formation of plates, which get a larger capacity, Standard Lead Acid Battery lead-acid batteries have a practical value.
With the progress of science and technology, lead-acid batteries after nearly 150 years, with the rapid development. From the beginning of the production of lead-antimony alloy plate, paste paste plate continuous improvement, the battery than the energy and reliability continue to improve, Standard Lead Acid Battery to achieve the normal temperature and low temperature of the high starting performance, low antimony multi-alloy and lead calcium alloy to achieve the lead The acid battery is less maintenance and maintenance-free.
Lead-acid batteries are acidic batteries, the most widely used, and its electrolyte from concentrated sulfuric acid and distilled water from the preparation of cadmium, nickel, iron, nickel batteries are alkaline batteries, their electrolytes are used potassium hydroxide solution, the working voltage Lighter than the lead-acid battery, the discharge current is greater, higher mechanical strength, smaller, longer life, Standard Lead Acid Battery the disadvantage is slightly higher cost, cadmium, nickel batteries for small electronic instruments, communications equipment, but also for aircraft, Artificial batteries, self-control and other related systems for the DC battery, another alkaline battery is zinc, silver batteries, electrolytic solution is also potassium hydroxide solution, with small size, light weight, large capacity characteristics, the same volume (or weight ) Than the other types of batteries than other types of batteries can store more than ten times the power can be large current discharge, Standard Lead Acid Battery the electrode is required to use silver, so the cost of expensive, zinc, silver batteries and camera flash, such as DC power supply, but Many battery discharge are accompanied by voltage instability, the use of the cycle is too short, the discharge time is too short and so on.
Chemical battery is actually the use of the original battery principle, Standard Lead Acid Battery the occurrence of spontaneous redox reaction, and its charging process is its reverse reaction.
Lead-acid battery cathode active material is lead dioxide, the anode active material is sponge lead, the electrolyte is dilute sulfuric acid solution, the discharge chemical reaction of lead dioxide, sea Jin lead and electrolyte reaction lead sulfate and water, Pb (negative) PbO2 (positive) 2H2SO4 ==== 2PbSO4 2H2O (discharge reaction), the charging chemical reaction for the lead sulfate and water into lead dioxide, Standard Lead Acid Battery sea Jin lead and dilute sulfuric acid, 2PbSO4 2H2O ==== Pb (negative) PbO2 ( The main series for the 6V, 12V for cars, motorcycles to start lighting use, single cell in general for the series of 48V, 96V, the standard battery voltage is 2.0V, the general series for the 6V, 12V for cars, , 110V or 220V for different occasions, the battery is positive and negative between the very low resistance. Impurities Small Components Stable ions can pass through rubber, PVC, PE or AGM partitions.
