Difference between colloidal battery and lead-acid battery

Gel battery

Colloidal lead-acid battery is an improvement of ordinary one for liquid electrolyte. Colloidal electrolyte substitute for sulfuric acid electrolyte, which is improved compared with ordinary battery in terms of safety, storage capacity, discharge performance and service life.

The colloidal lead-acid battery adopts a gel electrolyte, and there is no free liquid inside. The electrolyte capacity is large under the same volume, the heat capacity is large, and the heat dissipation ability is strong, which can avoid the thermal runaway phenomenon of the general storage battery; the electrolyte concentration is low, and the electrolyte plate is low. The corrosion effect is weak; the concentration is uniform, and there is no electrolyte stratification.

Working principle

The performance of colloidal lead-acid battery is better than that of 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 capacity. , cycle discharge capacity, deep discharge and high current discharge capacity, overcharge and over discharge self-protection.

The domestic colloidal lead-acid battery used for electric bicycle is vacuum infused in the AGM separator, and the silica gel and sulfuric acid solution poured between the positive and negative plates of the battery. The colloidal lead-acid battery cannot circulated in the initial stage of use. This is because the colloid encloses both the positive and negative plates. The oxygen generated on the positive plate cannot diffuse to the negative plate, and the lead reduction of the active material on the negative plate cannot achieve. It can only discharge by the exhaust valve, which is consistent with the flooded battery.

After the colloidal lead-acid battery used for a period, the colloid starts to crack and shrink, and cracks generate. The oxygen passes through the crack directly to the negative plate for oxygen circulation. The exhaust valve is no longer open frequently, and the colloidal lead-acid battery is close to sealing work, with little water loss. Therefore, the main failure of the electric bicycle battery is the water loss mechanism. The use of the colloidal lead-acid battery can achieve very good results. The colloidal electrolyte obtained by adding a gelling agent to the electrolyte to solidify the sulfuric acid electrolyte into a gelatinous substance. Usually, the colloidal electrolyte is further provided with a colloidal stabilizer and compatibilism, and some colloidal formulations provided with a retarding colloid solidification and retardation. To facilitate the filling of the gel.

Performance characteristics

1. The 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, no flow, no leakage, and uniform reaction of all parts of the plate.

3, using tight assembly technology, with excellent high rate discharge performance.

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

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

6, using gas recombination technology, the battery has a very high sealing reaction efficiency, no acid mist precipitation, safe and environmentally friendly, no pollution.

7. Special design and high reliability sealing technology ensure battery sealing, safe, and reliable use.

Application range

1. Communication systems: 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 systems

Second, lead-acid battery

The electrode is mainly made of lead and its oxide, and the electrolyte is a battery of a sulfuric acid solution. English: Lead-acid battery. In the discharge 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 components of the positive and negative electrodes are lead sulfate. Divided into exhaust battery and maintenance-free lead-acid battery.

Performance characteristics

1. Safety seal

In normal operation, the electrolyte does not leak out of the terminals or housing of the battery.

2. No free acid

The special aspirating separator keeps the acid inside and there is no free acid inside the battery, so the battery can place in any position.

3. The gas system

After the internal pressure of the battery exceeds the normal level, VRLA (Valve-Regulated Lead Acid Battery) is the battery that 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 compounding system converts the generated gas into water, no water need during the use of the battery.

5, long service life

A lead-calcium alloy fence with an anti-corrosion structure is used, and the battery can float for 10-15 years.

6. Stable quality, high reliability

Using advanced production technology and strict quality control system, the battery quality is stable and the performance is reliable. Voltage, capacity and seals are 100% tested on-line.

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

Colloidal lead-acid batteries are the same in performance as ordinary lead-acid batteries, except that the electrolyte inside the battery is a semi-solidified state of latex, and one is in a liquid state. The ordinary lead-acid battery in the liquid state needs to be irregular during use. The addition of distilled water maintained, and the colloid does not require the addition of distilled water for maintenance (commonly referred to as maintenance-free).

The disadvantage of colloidal lead-acid batteries is that overload, charge, and discharge are very harmful. If overload, charge, and discharge will cause battery to irreparable or even scrap. Ordinary lead acid needs to deform by battery, vulcanization can charge and discharged with a small current. Recovery (unable to restore original state) personally feel that colloid is clean and worry-free, ordinary lead-acid battery is more adaptable (adjustable in winter and summer).
