Lead acid battery electrolyte in the sulfuric acid directly involved in the battery charge and discharge reaction process, the traditional lead-acid batteries, the battery compartment to remove the plate, partitions and other solid assembly parts of the remaining space is full of sulfuric acid electrolyte, the electrolyte in surplus Excessive state, it is known as "rich liquid" battery, the battery plate completely soaked in sulfuric acid electrolyte. The top of the liquid-rich battery has a lid capable of venting and capable of blocking the spillage of the liquid. In the course of use, due to the evaporation and decomposition of moisture, it is necessary to periodically add the lid to add distilled water and adjust the electrolyte density. For the "open" battery. Rich liquid type lead-acid battery is characterized by cheap, long life, the disadvantage is the need for regular maintenance.
Also known as maintenance-free battery, divided into AGM sealed lead-acid batteries and GEL colloid sealed lead-acid batteries two. AGM type batteries use pure sulfuric acid aqueous solution as electrolyte, most of which exists in the glass fiber membrane, while the plate inside the suction part of the electrolyte. AGM-type sealed lead-acid battery electrolyte less, the thickness of the plate is thick, the utilization of active material is lower than the open-type battery, so the battery discharge capacity than the open battery is about 10% lower. Compared with today's colloidal sealed battery, its discharge capacity to be smaller. Compared with the same specifications of the battery type, the price is higher, has the following advantages: 1. Cycle charging capacity than the lead calcium battery 3 times higher, with a longer service life. 2. Has a higher capacity stability over the entire life cycle. 3. Low temperature performance is more reliable. 4. Reduce the risk of accidents and reduce the risk of environmental pollution (due to acid 100% sealed package) 5. Maintenance is very simple to reduce the depth of discharge.
Colloidal sealed lead-acid battery (ie, GEL-type battery), colloidal lead-acid battery is the liquid electrolyte of the ordinary lead-acid battery improvement, with colloidal electrolyte solution of sulfuric acid electrolyte, in the safety, storage capacity, discharge performance and service life And other aspects of the battery has improved compared to ordinary. The electrolyte is composed of silica sol and sulfuric acid, sulfuric acid solution concentration than AGM battery is lower, the amount of electrolyte than AGM type battery to be more, with rich liquid battery quite. This electrolyte exists in colloidal state, filled in the diaphragm and between the positive and negative, sulfuric acid electrolyte surrounded by the gel, will not flow out of the battery.
The advantages are as follows: GEL-type colloidal battery electrolyte electrolyte is no free electro-hydraulic, the probability of leakage of acid than the previous one much smaller; its perfusion than dilute sulfuric acid, less water loss, so the colloidal battery will not be lost Water caused by the failure of colloid filling increased the strength of the partition to protect the plate, make up the partition with acid shrinkage defects, so that the assembly pressure is not significantly reduced is one of the reasons for its extended battery life; colloid filled The gap between the separator and the plate reduces the internal resistance of the battery, and the charging capacity can be improved. So the colloid battery over discharge, recovery and low temperature charge and discharge performance than AGM battery superior.
1, can significantly extend the battery life. 2, body lead-acid battery self-discharge performance is good, in the same sulfuric acid purity and water quality, the battery storage time can be extended more than 2 times. 3, colloidal lead-acid batteries in the case of serious power shortage, anti-vulcanization performance is obvious. 4, colloidal lead-acid batteries in the case of severe discharge recovery ability. 5, colloidal lead-acid battery anti-overcharge capacity. 6, colloidal lead-acid battery late discharge performance.
