1. Gel battery
The colloidal lead-acid battery is an improvement of the ordinary lead-acid battery with liquid electrolyte. It replaces the sulfuric acid electrolyte with the colloidal electrolyte, which is better than ordinary batteries in terms of safety, storage capacity, discharge performance and service life.

The colloidal lead-acid battery adopts a gel-like electrolyte, and there is no free liquid inside. Under the same volume, the electrolyte capacity is large, the heat capacity is large, and the heat dissipation ability is strong. It can avoid the phenomenon of thermal runaway in general batteries; The corrosion effect is weak; the concentration is uniform, and there is no electrolyte layering phenomenon.

working principle
The performance of the colloidal lead-acid battery is better than the 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 long-term discharge ability. , Cycle discharge ability, deep discharge and high current discharge ability, have the advantages of overcharge and overdischarge self-protection.

The domestic colloidal lead-acid batteries used for electric bicycles are vacuum-filled in the AGM separator, and the silica gel and sulfuric acid solution are poured between the positive and negative plates of the battery. Colloidal lead-acid batteries cannot carry out oxygen circulation in the early stage of use. This is because the colloid surrounds both the positive and negative plates. Oxygen generated on the positive plate cannot diffuse to the negative plate and cannot be reduced with the active material lead on the negative plate. It can only be discharged by the exhaust valve, which is consistent with the flooded battery.

After the colloidal lead-acid battery is used for a period of time, the colloid begins to crack and shrink, resulting in cracks, and oxygen passes through the cracks directly to the negative plate for oxygen circulation. The exhaust valve is no longer frequently opened, and the colloidal lead-acid battery is close to the sealing operation, and there is little water loss. Therefore, the main failure of the electric bicycle battery is the loss of water mechanism, and the use of colloidal lead-acid batteries can achieve very good results. The colloidal electrolyte solidifies 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, and some colloidal formulations are also added to retard colloidal coagulation and retardation To facilitate colloid filling.

The difference between gel battery and lead-acid battery

Performance characteristics

1. Fumed silica is prepared with high-quality colloid, the electrolyte is evenly distributed, and there is no acid stratification.

2. The electrolyte is in a gel-fixed state, does not flow, and does not leak, so that all parts of the electrode plate react evenly.

3. Using tight assembly technology, it has excellent high-rate discharge performance.

4. Excess electrolyte, the battery has large heat capacity, strong heat dissipation ability, and wide operating temperature range.

5. All high-purity raw materials are used, and the self-discharge electrode of the battery is small.

6. Adopting gas recombination technology, the battery has extremely high sealing reaction efficiency, no acid mist precipitation, safety and environmental protection, and no pollution.

7. Special design and highly reliable sealing technology are adopted to ensure that the battery is sealed, safe and reliable in use.

Scope of application

1. Communication system: switches, microwave stations, mobile base stations, data centers, radio and broadcasting stations.

2. Power plants and power transmission and transformation systems;

3. Solar and wind power generation systems

4. Signal system and emergency lighting system

5. EPS and UPS system

2. Lead-acid battery

The electrode is mainly made of lead and its oxide, and the electrolyte is a kind of storage battery with sulfuric acid solution. English: Lead-acidbattery. In the discharged state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charged state, the main component of the positive and negative electrodes are lead sulfate. Divided into exhaust-type batteries and maintenance-free lead-acid batteries.

Performance characteristics

1. Safety seal
In normal operation, the electrolyte will not leak out of the battery terminal or case.

2. No free acid
The special absorbent separator keeps the acid inside, and there is no free acid inside the battery, so the battery can be placed in any position.

3. Deflation system
When the internal pressure of the battery exceeds the normal level, the VRLA (Valve-Regulated LeadAcid Battery, the abbreviation of "Valve-Regulated Lead Acid Battery") will release excess gas and automatically reseal to ensure that there is no excess gas in the battery.

4. Simple maintenance
Since the unique gas compound system converts the generated gas into water, there is no need to add water during the battery use.

5. Long service life

The lead-calcium alloy fence with anti-corrosion structure is adopted, and the battery can be used for floating charge for 10-15 years.

6. Stable quality and high reliability

Using 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 on the line.

The difference between gel battery and lead-acid battery
Third, the difference between gel batteries and lead-acid batteries

The performance of colloidal lead-acid batteries is the same as that of ordinary lead-acid batteries, except that one of the electrolytes in the battery is in a semi-solidified state and the other is in a liquid state. The ordinary lead-acid batteries in liquid state need to be irregular during use. Add distilled water for maintenance, colloid does not need to add distilled water for maintenance (commonly referred to as maintenance-free).

The disadvantage of colloidal lead-acid batteries is that overload charging and discharging is very harmful. Once overloaded, charging and discharging will cause irreversibility of the battery, or even scrap, while ordinary lead-acid batteries require the deformation and vulcanization of the plate caused by battery overload, which can be charged and discharged with a small current. Recovery (but it can't be restored to the original state); I personally feel that the colloid is clean and worry-free, and the adaptability of ordinary lead-acid batteries is better (adjustable in winter and summer).
