The Discharge Rate Of Lead-acid Batteries Is Varied
- Sep 12, 2017 -

Lead-acid battery, also known as lead battery, is a kind of battery, electrode is mainly made of lead and its oxides, electrolyte is a kind of battery of sulfuric acid solution. English: Lead-acid Battery under the state of charge, the main components of the cathode are lead dioxide, the main negative electrode is lead, Standard Lead Acid Battery and the main components of the positive and negative electrode are lead sulfate in the discharge state. Generally divided into open-type battery and valve-controlled battery two kinds. Standard Lead Acid Battery The former needs regular acid-injection maintenance, the latter is a maintenance-free battery. According to the battery model can be divided into small, medium and dense. The main advantages are voltage stability, low price.

Lead-acid battery is a reversible device that converts energy and chemical energy to each other, that is to say: The charge is to store the electricity, Standard Lead Acid Battery and the discharge is to turn the chemical energy into electricity to release it. Lead-acid battery consists of positive plate, negative plate, glass fiber separator, electrolyte and electrolytic cell, the active substance of the positive electrode after charging is lead dioxide, Standard Lead Acid Battery the active substance of the negative plate is sponge-like lead, the active material of the plate after discharge is changed to lead sulfate, and then the original material is restored after charging.

Classification of use of lead-acid batteries

A. For A variety of automobiles, tractors, diesel engines starting and ignition, lighting use, starting at the request of large current discharge, low temperature start-up, small battery resistance;

B. For power plants, substations, communications, hospitals, such as protection, automatic control, accident lighting, communications and other standby power supply, Standard Lead Acid Battery electrolytic liquid dilute, long life, Chun full use;

C. For a variety of lead-acid battery vehicles, forklifts, forklifts, mining electric locomotives and so on. It is used as electric traction and illumination power, requires thick plate, large capacity, Standard Lead Acid Battery and charge and discharge cycle using 3h~5h rate;

D. The size of bulk density varies, and the discharge rate varies.

What are the characteristics of lead-acid battery discharging?

1 The discharge leads to the decrease of the concentration of sulfuric acid in the electrolyte, which leads to the decrease of electrolyte density, Standard Lead Acid Battery so the method of detecting the electrolyte density can be used as the standard to judge the discharge degree of lead-acid battery and to measure the discharge termination. According to experience, the capacity of the lead-acid battery is about 10% when the voltage drops 0.1 v. 2 The discharge makes the positive and negative electrode lead to increase,. Standard Lead Acid Battery The internal resistance increases, the electrolyte concentration drops, the lead acid battery voltage reduces, so the measuring lead-acid battery terminal voltage can also be used to judge the discharge degree of lead-acid battery and to measure the discharge termination standard. The characteristic of lead-acid battery when charging is opposite to discharging.
