The Capacity Of GEL Battery

 

The capacity of gel batteries can vary based on different battery models and brands. Typically, battery capacity is measured in ampere-hours (Ah), which represents the duration of current the battery can provide in one hour. Here are some common gel battery capacity ranges:
Small gel batteries: usually have lower capacities, such as 1Ah to 20Ah, and are suitable for small portable devices, emergency power backup and other applications.
Medium-sized gel battery: The capacity range is usually between 20Ah and 100Ah. It is suitable for general vehicle starting batteries, energy storage batteries for solar systems and other applications.
Large gel batteries: These batteries have higher capacities, usually above 100Ah, and are suitable for applications that require continuous power supply for a long time, such as UPS systems, solar power stations, etc.
 

Plate Selection For Gel Batteries

 

Lead-Calcium Plates: Lead-Calcium Plates are one of the common gel battery plates. They use an alloy of lead and calcium as electrode material, which has high electrolyte density and battery capacity, and also has strong resistance to self-discharge. Lead-calcium plates are commonly used in applications requiring high capacity and low self-discharge characteristics.

Lead-Tin Plates: Lead-Tin Plates are another common gel battery plate. They use an alloy of lead and tin as electrode material, which has high corrosion resistance and long life. Lead-tin plates are typically used in applications requiring higher cycle life and plate corrosion resistance.

Hybrid Plates: Hybrid plates combine different types of materials such as lead-calcium, lead-tin, and other alloys. The plates are designed to balance properties such as capacity, cycle life and self-discharge. Hybrid plates are often used in applications that require a combination of high capacity and long life.

The Role Of Gel In GEL Batteries

 

Prevent leakage: Gel-solidified electrolyte can effectively prevent battery electrolyte leakage. Compared with liquid electrolytes, gel batteries are safer and more reliable during use and transportation.

Inhibit sulfuration: The gel structure can inhibit the sulfurization reaction in the battery. Vulcanization is a common failure mechanism in gel batteries that results in reduced battery capacity and cycle life. Through the formation of gel structure, the occurrence of sulfation reaction can be reduced and the stability and life of the battery can be improved.

Increase the contact area of the battery's active materials: The gel structure has a larger surface area, which can increase the contact area between the active materials and the electrodes, improving the battery's electrochemical reaction efficiency and energy output capability.

Effect of temperature on performance and life of gel batteries：
 
Capacity change: Temperature has a significant impact on battery capacity. Normally, as the temperature increases, the capacity of the gel battery increases, while the decrease in temperature causes the capacity to decrease. This is because electrochemical reactions proceed faster at higher temperatures, the electrolyte inside the battery becomes more active, and the reaction rate of the electrodes increases.
 
Changes in internal resistance: Temperature changes can also cause changes in the internal resistance of gel batteries. At higher temperatures, the battery's internal resistance decreases, current can flow through the battery more smoothly, and the battery's output power increases. At lower temperatures, the internal resistance of the battery increases, the battery's output power decreases, and it may be difficult to start.
 
Self-discharge: Temperature has an impact on the self-discharge rate of gel batteries. Self-discharge is the process by which a battery loses its charge on its own when not in use. Higher temperatures cause the battery's self-discharge rate to increase, which reduces the battery's storage capacity and usable time.
 
Lifespan: Temperature is one of the important factors affecting the lifespan of gel batteries. Temperatures that are too high or too low will shorten battery life. At higher temperatures, the rate of chemical reactions inside the battery accelerates, which may lead to corrosion of the battery's plates and loss of active materials. At lower temperatures, the chemical reaction rate of the battery decreases, which may lead to a decrease in battery capacity and damage to the electrode structure.
 
Therefore, when using gel batteries, you should try to avoid too high or too low operating temperatures and choose an appropriate operating temperature range to improve battery performance and life. At the same time, for application scenarios with low ambient temperatures, insulation measures can be considered to provide a suitable working temperature.
