Will the electrolyte for full floating charge operation of double-access battery be reduced?

The electrolyte inside the Shuangdeng battery is adsorbed in the battery diaphragm, and there is no free electrolyte. It is a typical lean-liquid battery. If the floating charge voltage is high or the battery is used in a high temperature environment for a long time, the water loss rate of the battery will be accelerated, resulting in drying out failure. Experiments show that adding a certain amount of water can effectively reduce the polarization during charging and discharging, restore the actual capacity of the battery and prolong the life of the battery. Shuangdeng batteries; ambient temperature; drying out failure; water dispersion causes the electrolyte inside the battery (VRLAB) to be adsorbed in the battery diaphragm. There is no free electrolyte. It is a typical lean-liquid battery.



Shuangdeng batteries are praised by users because of their simple operation and maintenance, less harmful gas released, and greatly reduced environmental pollution. After the operation and use in recent years, some problems have also been exposed, mainly in its short life, generally less than 5 years, which is far from the standard requirements of its design life of more than 10 years. Through the analysis and test of several failed batteries, it is proved that many batteries are due to improper use or excessive ambient temperature, resulting in excessive water loss of batteries, making the chemical reaction of batteries impossible, leading to premature termination of the life of double-access batteries. Shuangdeng batteries must be recharged in the following circumstances. When the battery system is installed, the batteries should be recharged before putting into operation. The batteries should be recharged every three months. When the voltage of more than two batteries is lower than 2.18V, Beijing Huakelida Science and Technology reminds you that Shuangdeng batteries should be put on hold for more than five months, and Shuangdeng batteries should be fully recharged. Three months.



Cause analysis and treatment of dry-up failure of double-access batteries. If the floating charge voltage is too high for a long time, it will cause a large amount of electrolysis and loss of water in the electrolyte, resulting in the drying up of the battery. Experiments show that adding a certain amount of water can effectively reduce the polarization during charging and discharging, restore the actual capacity of the battery and prolong the life of the battery. Shuangdeng batteries; ambient temperature; drying out failure; water dispersion causes the electrolyte inside the battery (VRLAB) to be adsorbed in the battery diaphragm.

Since its inception, Shuangdeng battery has been praised by users for its simple operation and maintenance, less harmful gas released, and greatly reduced environmental pollution. After the operation and use in recent years, some problems have also been exposed, mainly in its short life, generally less than 5 years, which is far from the standard requirements of its design life of more than 10 years. Through the analysis and test of several failed batteries, it is proved that many batteries are due to improper use or excessive ambient temperature, resulting in excessive water loss of batteries, making the chemical reaction of batteries impossible, leading to premature termination of the life of double-access batteries. Shuangdeng batteries must be recharged in the following circumstances. After the installation of the battery system, the batteries should be recharged before putting into operation. The batteries should be recharged every three months, or when the voltage of more than two batteries is less than 2.18V, the shelf time of Shuangdeng batteries exceeds five months, and the full floating operation of Shuangdeng batteries lasts for three months. Because floating charging voltage is the long-term charging voltage of Shuangdeng batteries, in general, the full floating charging voltage is 2.23-2.25V/monomer (25 C). If we do not work within this floating charge range, but use 2.35V/monomer (25 C), the thermal runaway will occur for 4 months; or 2.30V/monomer (25 C), the thermal runaway will occur for 6 to 8 months; if we use 2.28V/monomer (25 C), the capacity will decline seriously for 12 to 18 months, which will lead to thermal runaway. The direct consequence of thermal runaway is bulging and leaking of the battery's shell. Shuangdeng battery loses its discharge function, and finally only scraps. Therefore, the battery should be selected reasonably in floating charging. Reasonable selection is a crucial factor affecting the life of double-access battery.
