1. Gel battery
The colloidal lead-acid battery improves the ordinary lead-acid battery with liquid electrolyte. The sulfuric acid electrolyte is replaced by the colloidal electrolyte, which is improved compared with standard batteries in safety, storage capacity, discharge performance, and service life.
The colloidal lead-acid battery uses a gel-like electrolyte, and there is no free liquid inside. Under the same volume, the electrolyte has a large capacity, a large heat capacity, and a robust heat dissipation ability, which can avoid the thermal runaway phenomenon that is easy to occur in general batteries; the electrolyte concentration is low. The corrosion effect is weak; the attention is uniform, and there is no electrolyte stratification.
working principle
The performance of a colloidal lead-acid battery is better than that of a valve-regulated sealed lead-acid battery. The colloidal lead-acid battery has stable performance, high reliability, long service life, strong adaptability to ambient temperature (high and low temperature), and withstand long-term discharge. , Cyclic discharge capacity, deep discharge, and high current discharge capacity have the advantages of overcharge and over-discharge self-protection.
The domestic colloidal lead-acid battery used for electric bicycles is poured into the AGM separator by vacuum infusion. The silica gel and sulfuric acid solution are poured between the positive and negative plates of the battery. The colloidal lead-acid battery cannot carry out oxygen circulation in the early use stage because the colloid surrounds the positive and negative vessels. The oxygen generated on the positive plate cannot diffuse to the negative plate. The active material on the negative scale cannot achieve lead reduction. The exhaust valve can only be discharged, which is consistent with the flooded battery.
After the colloidal lead-acid battery is used for a while, the colloid begins to crack and shrink, resulting in cracks. Oxygen goes directly to the negative plate through the trials for oxygen circulation. The exhaust valve is no longer opened frequently, and the colloidal lead-acid battery is close to sealing, with slight water loss. Therefore, the primary failure of electric bicycle batteries is the water loss mechanism, and colloidal lead-acid batteries can achieve excellent results. The colloidal electrolyte is to solidify the sulfuric acid electrolyte into a colloidal substance by adding a gelling agent to the electrolyte. Usually, colloidal stabilizers and compatibilizers are added to the colloidal electrolyte—agent for easy colloid filling.
The difference between gel battery and lead-acid battery
Performance characteristics
1. Fumed silica is used to prepare high-quality colloids, the electrolyte is evenly distributed, and there is no acid stratification phenomenon.
2. The electrolyte is in a gel-fixed state, with no flow no leakage, so that each part of the plate reacts evenly.
3. Using tight assembly technology, it has excellent high-rate discharge performance.
4. Excessive electrolyte, the battery has a large heat capacity, strong heat dissipation ability, and wide operating temperature range.
5. All high-purity raw materials are used, and the battery self-discharge electrode is small.

2. Lead-acid battery
The electrodes are mainly made of lead and its oxides, and the electrolyte is a battery of sulfuric acid solution. English: Lead-acid battery. In the discharge state, the main component of the positive electrode is lead dioxide. The main element of the negative electrode is lead; in the charged state, the central part of the positive and negative electrodes is lead sulfate. They are divided into vented batteries and maintenance-free lead-acid batteries.
Performance characteristics
1. Safety seal
During regular operation, the electrolyte will not leak from the terminals or the battery's casing.
2. No free acid
Special wicking separators keep the acid inside, and there is no free acid inside the battery so that the battery can be placed anywhere.
3. Air deflation system
When the battery's internal pressure exceeds the average level, the VRLA (Valve-Regulated Lead Acid Battery) battery will release excess gas and automatically reseal it to ensure that there is no excess gas in the storm.
4. Simple maintenance
Since the unique gas recombination system converts the generated gas into water, there is no need to add water during the use of the battery.
5. Long service life
The lead-calcium alloy fence with an anti-corrosion structure is adopted, and the battery can be used for 10-15 years on a floating charge.
6. Stable quality and high reliability
Adopt advanced production technology and strict quality control system, the quality of the battery is stable, and the performance is reliable. Voltage, capacity, and sealing are 100% inspected online.

The difference between gel battery and lead-acid battery
Third, the difference between gel battery and lead-acid battery.
Colloidal lead-acid batteries have the same performance as ordinary lead-acid batteries, except that the electrolyte in the battery is in a semi-solidified state of latex, and the other is in a liquid form. Standard lead-acid batteries in a liquid state need to be used irregularly. With distilled water for maintenance, the colloid does not need to add distilled water for care (usually called maintenance-free).
The disadvantage of colloidal lead-acid batteries is that overload charging and discharging are harmful. Once overloaded charging and discharging will cause the battery to be irrecoverable or even scrapped. In contrast, ordinary lead-acid batteries require the deformation and vulcanization of the plates caused by the overload of the storm, which can be charged and discharged with a slight current. Recovery (just cannot be restored to the original state); I feel that the colloid is clean and worry-free, and the adaptability of ordinary lead-acid batteries is better (adjustable in winter and summer).
