What are the advantages and disadvantages of gel batteries

1. The advantages of colloidal batteries are high quality and long service life. The colloidal solid electrolyte can form a solid protective layer on the electrode plate to prevent the electrode plate from being corroded. It also reduces the plate bending phenomenon and the electrode plate short circuit when the battery is used under heavy load, and better prevents the active material of the electrode plate from softening and falling off. , It has good physical and chemical protection purposes, and is 1.5 to 2 times the life of traditional lead-acid batteries in the national testing standard. The colloidal electrolyte has a scientific specific gravity and is not easy to cause vulcanization of the plate. Under normal use, the number of cycles is more than 550. It is safe to use and environmentally friendly. There is no acid mist gas precipitation, no electrolyte overflow, no combustion, no explosion, no corrosion to the car body, no pollution. Since the electrolyte is solid, even if the battery shell ruptures accidentally during use, it can still be used normally, and no liquid sulfuric acid can flow out. High efficiency and good performance. The self-discharge of colloidal batteries is small, which is conducive to long-term storage; the deep discharge performance is high, which is conducive to improving the utilization rate of active materials and the discharge capacity; the recovery ability of deep discharge and overdischarge is strong, and the charge acceptance ability exceeds the national standard by more than 50%. It is convenient and quick to use, without frequent maintenance. The surface of the product is clean and free of dirt; one-time electrolyte perfusion, which will never add acid for life, can save a lot of energy and maintenance and maintenance costs. Less water loss. The oxygen circulation design has pores that facilitate the diffusion of oxygen, and the precipitated oxygen can chemically react with the negative electrode material, so there is less gas evolution during the charge and discharge process, and less water loss. Shelve for a long time. It has good resistance to plate sulfation and reduction of grid corrosion, and has a long storage period. Less self-discharge. It can hinder the diffusion of water generated during cathode reduction and suppress the spontaneous reduction reaction of PbO, so there is less self-discharge. Good starting performance at low temperature. Because the sulfuric acid electrolyte exists in the gel, although the internal resistance is slightly larger, the internal resistance of the gel electrolyte does not change much at low temperatures, so its low-temperature start-up performance is good. High charging efficiency. The special charging method can fully activate the active material and increase the battery capacity. The use environment (temperature) is wide, especially suitable for cold weather in Northeast China. The gel battery can be used normally within the temperature difference range of -40℃～65℃, which effectively solves the problem of difficulty in starting up with traditional lead-acid batteries in the high-cold areas and other high-temperature areas in northern my country in the past. 2. Disadvantages of colloidal batteries The rubber particles brought out by the early exhaust are acid-containing, and the rubber particles are easy to stick to the battery shell, so some users will report the battery leakage. Although the oxygen cycle inhibits water loss, the excellent oxygen cycle also generates heat, which increases the internal temperature of the battery, and the gel battery has a thermal runaway phenomenon.
