The performance of colloidal lead acid battery is better than that of valve regulated sealed lead acid battery. The colloidal lead acid battery has the advantages of stable service performance, high reliability, long service life, strong adaptability to environmental temperature (high and low temperature), strong ability to withstand long time discharge, cyclic discharge, deep discharge and large current discharge, overcharge and over discharge self-protection.
At present, the domestic gel lead acid battery used for electric bicycles is filled between the positive and negative plates of the battery through vacuum filling in the AGM separator. The colloid lead-acid battery cannot carry out oxygen circulation at the initial stage of use, because the colloid encloses the positive and negative plates, and the oxygen generated on the positive plate cannot diffuse to the negative plate, which cannot achieve the reduction of the active substance lead on the negative plate. It can only be discharged by the exhaust valve, which is consistent with the rich liquid battery.
After the colloid lead-acid battery has been used for a period of time, the colloid begins to dry and shrink, resulting in cracks. The oxygen circulates directly to the negative plate through the cracks. The exhaust valve is no longer open frequently, and the colloid lead-acid battery is close to the sealing work, with little water loss. Therefore, the main failure of the electric bicycle battery is the water loss mechanism, and the gel lead acid battery can achieve very good results. Colloidal electrolyte coagulates sulfuric acid electrolyte into colloidal substances by adding gel agent to the electrolyte. Generally, colloidal electrolyte is also added with colloidal stabilizer and compatibilizer, and some colloidal formulas are also added with delayed colloidal coagulation and retarding agent to facilitate colloidal filling.
