Gel battery internal resistance and high current discharge capacity  

Release date:2021-07-15 Author:kanglida battery Click:

The gel battery is a lead-acid battery that adds a gelling agent to sulfuric acid to make the sulfuric acid electro-liquid become colloidal. The difference from conventional lead-acid batteries is not only that the electro-hydraulic is changed to a gelatinous state. For example, non-solid hydrocolloids belong to colloidal batteries from the perspective of electrochemical classification structure and characteristics. Another example is the attachment of polymer materials in the grid, commonly known as ceramic grids, which can also be regarded as the application characteristics of gel batteries. Recently, laboratories have added a targeted coupling agent to the plate formula, which greatly improves the reaction utilization rate of the plate active material. According to non-public data, it can reach a weight ratio energy level of 70wh/kg.

   What are the internal resistance and high-current discharge capability of colloidal batteries? ? How much do you know about this problem? ? Today, the editor of Zhengzhou Kanglida Electronic Power Supply Co., Ltd. will give you some information on this issue. I hope it will be helpful to you. In the future, you can avoid detours when using and purchasing.

Gel battery internal resistance and high current discharge capacity  

   The internal resistance of lead storage batteries is composed of ohmic internal resistance, concentration polarization internal resistance, and electrochemical polarization internal resistance. The former includes plates, lead parts, electrolyte, and barrier resistors. The glass fiber separator used in the AGM sealed lead battery has a porosity of 90%, and sulfuric acid is adsorbed in it. The battery adopts a tightly assembled form. The diffusion and electromigration of ions in the separator are very small. Therefore, the AGM sealed lead battery has Low internal resistance, high-current rapid discharge capability is very strong.

The electrolyte of a colloidal sealed lead battery is a silicone gel. Although the diffusion speed of ions in the gel is close to the diffusion speed of the aqueous solution, the migration and diffusion of ions are affected by the structure of the gel, and the diffusion of ions in the gel The more curved the path, the narrower the pores in the structure, and the greater the obstruction. Therefore, the internal resistance of the colloidal sealed lead battery is larger than that of the AGM sealed lead battery.

   However, the test results show that the high-current discharge performance of the gel-sealed lead storage battery is still very good, which fully meets the requirements of the relevant standards for the high-current discharge performance of the sealed battery. This may be because the concentration of acid and other related ions in the liquid layer inside the porous electrode and near the electrode plate play a key role in the large current discharge.
