Features of gel battery


  Gel batteries belong to a development category of lead-acid batteries. The method is to add a gelling agent to sulfuric acid to make the sulfuric acid electro-liquid become colloidal. Batteries in which the electrolyte is in a gel state are usually called gel batteries. The difference between the gel battery and the conventional lead-acid battery is from the initial understanding of electrolyte gelation to the study of the electrochemical characteristics of the electrolyte basic structure, as well as the application and promotion of grids and active materials. Its most important feature is: use a small industrial cost to produce a better quality battery, its discharge curve is straight, the inflection point is high, its energy and power are more than 20% larger than conventional lead-acid batteries, and the lifespan is generally conventional lead. The acid battery is about twice as long, and its high temperature and low temperature characteristics are much better.


 The main advantages of colloidal batteries: high quality and long cycle life. The colloidal electrolyte can form a solid protective layer around the electrode plates to protect the electrode plates from damage and breakage due to vibration or collision, prevent the electrode plates from being corroded, and also reduce the bending and inter-electrode plate bending of the battery during heavy load use The short circuit will not lead to a decrease in capacity, and has good physical and chemical protection, which is twice the life of ordinary lead-acid batteries.

 It is safe to use, environmentally friendly, and belongs to the true sense of green power. The electrolyte of the gel battery is solid, sealed structure, and the gel electrolyte never leaks, so that the specific gravity of each part of the battery is consistent. The use of a special calcium-lead-tin alloy grid is more resistant to corrosion and has better charging acceptance. Use ultra-high-strength partitions to avoid short circuits. Imported high-quality safety valve, precise valve control to adjust the pressure. Equipped with a filter acid mist explosion-proof device, which is safer and more reliable. There is no acid mist gas precipitation during use, no electrolyte spillage, no harmful elements to the human body during the production process, non-toxic, non-polluting, and avoiding a large amount of electrolyte spillover and penetration during use of traditional lead-acid batteries. The float charge current is small, the battery generates less heat, and the electrolyte does not undergo acid stratification.

 Deep discharge cycle performance is good. After the battery is deeply discharged and then recharged in time, the capacity can be 100% recharged, which can meet the needs of high frequency and deep discharge, so its use range is wider than that of lead-acid batteries.

 The self-discharge is small, the deep discharge performance is good, the charge acceptance is strong, the upper and lower potential difference is small, and the electric capacity is large. Significantly improved in low temperature starting ability, charge retention capacity, electrolyte retention capacity, cycle durability, vibration resistance, and temperature change resistance. Stored at 20℃ room temperature for 2 years, it can be put into operation without charging.

 Adapt to a wide range of environments (temperatures). It can be used in the temperature range of -40℃-65℃, especially the low temperature performance is good, suitable for the northern alpine region. It has good seismic performance and can be used safely in various harsh environments. Not limited by space, it can be placed in any position when in use.

  It is quick and easy to use. Because the internal resistance, capacity, and float voltage of the single battery are consistent, there is no need for equalizing charging and frequent maintenance.


Due to these characteristics of gel batteries, the batteries in our solar power system are all gel batteries. For more information, please check the link:
