In the traditional flooded lead-acid battery, the separator only acts as an inert spacer to prevent the short circuit of the positive and negative electrodes. It needs to have good ionic conductivity, the manufacturing method is matched with the production process, the physical and chemical properties have long-term stability, etc.

Formation, which means conversion, is the process in which the cured green plate is converted into a cooked plate under the action of electric energy.

The working principle of VRLAB can be summarized as follows:
·The positive electrode plate undergoes water decomposition reaction, which causes O2 precipitation and generates H+ ions.
·O2 and H+ ions diffuse to the negative electrode plate through the gas channel and the liquid channel in the separator.
·After reaching the negative electrode plate, oxygen reacts with H+ ions to generate water.
·The generated water is diffused to the positive electrode plate through the separator, so that the water electrolyzed by the positive electrode plate is recovered.
The above reaction forms the so-called closed oxygen cycle (COC). The closed oxygen cycle significantly reduces the battery's water loss during charging and overcharging, making it maintenance-free.

Pb-Ca-Sn alloy grids are used in lead-acid batteries, and hydrogen evolution inhibitors are added to the negative plates. The wet charging technology is widely used in the battery industry. After limiting the charging voltage, these batteries can be considered maintenance-free. However, their service life is very dependent on the charging conditions that need to be strictly observed, in particular the limitation of the maximum charging voltage. Battery engineers and producers are looking for ways to recycle into water the H2 and O2 released during battery charging and overcharging. In this way, the problem of water loss can be solved.

For flooded batteries, the basic function of micro-porous separator is to isolate the plates with opposite polarity, avoid electrical contact between them, and ensure high ionic conductivity at the same time, allowing ions to move freely between the plates.

Gauntlets are the most important parts of the tubular battery, which ensure good contact between the Positive Active Material and the positive plate spines, better containing any shedding of this material during charge and discharge phases, and allowing for easier production of these plates at the same time. Our gauntlets are particularly suitable for all types of filling.

The time required for the PvC separator, PE separator, rubber separator, and PP separator to achieve stable resistance is different. This is mainly due to the different main materials used for the separator, and the different time it takes for the separator to be completely wetted by the sulfuric acid solution. Different ratios and apertures, the PP separator takes the shortest time to stabilize the resistance, the PE separator takes the longest time, the PVC separator and the rubber separator are in the middle, and the PVC separator takes a slightly shorter time than the rubber separator.

According to the different batteries, the requirements for the hydrophilic wettability of the separator are also different (eg: PE separator, PVC separator, PP separator, etc.) The wet-type charged battery requires that the separator of the battery has good re wettability, that is, after the first wetting, whether the separator is air dried or not, it is required to have another hydrophilic wettability.

The function of the PE separator is to separate the positive and negative plates that rely on each other to prevent short circuits due to contact with each other. The PE separator material should have good acid resistance and oxidation resistance. Commonly used separators include wooden separators, microporous rubber separators, microporous plastic glass fibers and cardboard. PE separators usually have grooves on one side.

The lead-acid battery was created by the Frenchman G.Plante. Samples were sent to the French Academy of Sciences in 1860. At that time, the battery was the only new thing in the laboratory. It was not until 13 years later (in 1873) , the DC generator came out, and the lead-acid battery gradually became practical.

Lead acid batteries have existed since the end of the 19th century. They have the characteristics of high performance, low cost, easy recovery and charging. Their efficiency is relatively high, about 80 – 90%. However, when high power is discharged, the available capacity of the batteries is reduced. Therefore, the discharge depth of lead acid battery is limited.
