The colloidal lead-acid battery is an improvement of the ordinary lead-acid battery with liquid electrolyte. The sulfuric acid electrolyte is replaced by a colloidal electrolyte, and the safety, power storage, discharge performance, and service life are improved compared with the ordinary battery.

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

Working principle:

The performance of the colloidal lead-acid battery is better than that of the valve-controlled sealed lead-acid battery. The colloidal lead-acid battery has the advantages of stable performance, high reliability, long service life, strong adaptability to the ambient temperature (high and low temperature), strong ability to withstand long-term discharge, cyclic discharge, deep discharge and large current discharge, and self-protection of overcharge and over-discharge.

The colloidal lead-acid battery is filled by vacuum 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 can not be used in the initial oxygen cycle, this is because the colloid is surrounded by positive and negative plates, the oxygen generated above the positive plate can not be diffused to the negative plate, which can not be achieved with the active substance lead reduction on the negative plate, can only be discharged by the exhaust valve, consistent with the liquid-rich battery.


After the colloidal battery is used for some time, the colloid begins to dry and shrink, resulting in cracks, and oxygen is circulated directly to the negative plate through the cracks. The exhaust valve is no longer often opened, the colloidal lead-acid battery is close to the seal work, and the water loss is very little. Therefore, for the use of solar photovoltaic power generation systems in the field, the use of colloidal batteries can obtain very good results. The colloidal electrolyte is the sulfuric acid electrolyte solidified into a colloidal substance by adding a gelling agent to the electrolyte, usually, the colloidal electrolyte is also added with a colloidal stabilizer and capacitator, and the colloidal formula is also added with a delay of colloidal solidification and a delay agent to facilitate the addition of colloidal filling.


Performance characteristics:

1, fumed silica preparation of high-quality colloids, electrolyte distribution is uniform, and there is no acid stratification phenomenon.

2, the electrolyte is in a gel-fixed state, with no flow or leakage, so that each part of the plate reacts evenly.

3, the use of tight assembly technology, with excellent high-rate discharge performance.

4, excessive electrolyte, battery heat capacity is large, heat dissipation capacity is strong, wide operating temperature range.

5, all the use of high-purity raw materials and battery self-discharge is very small.

6, with the use of gas recombination technology, the battery has a very high sealing reaction efficiency, no acid fog precipitation, safety and environmental protection, and no pollution.

7, the use of special design and highly reliable sealing technology to ensure that the battery is sealed, safe, and reliable to use.
