Unlike simple acid batteries, gel batteries have many advantages. All this is ensured due to the fact that in such batteries the electrolyte is in a jelly-like state.
Design features and scope
The mechanism of operation of this device is quite simple: due to the redox reaction, which occurs as a result of the interaction of the lead plates with the electrolyte, the battery is able to accumulate electrical energy and consume it as needed.
If in simple batteries sulfuric acid acts as an electrolyte, here it is presented in the form of a gel. The gel is obtained by adding silicon to the solution.
Until recently, gel batteries were used very limited due to their high cost. But in recent years, they have become more affordable and have made acid batteries more competitive.
Gel batteries are widely used in the automotive industry. They are used as starter batteries for scooters and motorcycles. Because the devices promote traction, they are used in the manufacture of wheelchairs and electric vehicles. Due to the fact that gel-based accumulators accumulate energy better, they are used as accumulators of electric current in solar and wind power plants. In addition, gel-based battery devices are part of modern medical equipment, photovoltaic devices.
Advantages of gel batteries
Modern gel batteries have many advantages over acid batteries. First, due to its state of aggregation, the electrolyte does not leak out. This ensures the tightness of the structure. In this case, you can use the battery in almost any position.
Secondly, the gel filler does not corrode and sulfate metal plates. This ensures the reliability and durability of the structure. Compared to acid batteries, they last about 2 times longer.
Thirdly, gel batteries are less sensitive to deep discharge. The gel prevents the evaporation of the electrolyte, as a result of which the lead contacts do not corrode. It should be noted that the evaporation of the gel during the operation of the equipment practically does not occur, this allows you to maintain the volume of electrolyte at the proper level and save it.
Fourth, gel-based batteries can last much longer. This is due to the fact that they discharge very slowly. Gel, unlike acid, is more stable at low and high temperatures, so it can be used at temperatures from -40 to +50 degrees.
Gel equipment works better at high air humidity, gives a high current. Thus, gel batteries are the most reliable and durable.
