Redox Flow Battery Features
Redox Flow Battery Features
１．High Safety
The vanadium sulfate used as the electrolyte is nonflammable. So even if positive and negative liquids are mixed, they will not ignite. Flame-retardant materials are also used for other parts of the battery, thus significantly reducing the possibility of fire and ensuring a high degree of safety. In addition, the cell stack has been certified with the US safety standard, UL 1973.
2. Eco-friendly
Unlike other batteries, redox flow batteries do not have electrode dissolution or deposition due to charge/discharge reaction. This means no degradation of the electrodes or electrolyte. The electrolyte can be reused and recycled. It’s safe to say the redox flow battery is an eco-friendly circular product with a long service life and no degradation. Our redox flow battery makes circular economy possible.
3. Long life
The battery reaction principle is simply the change of valence of the vanadium ions in the electrolyte (without deposition and dissolution); therefore the life of electrolyte is not susceptible.
4. Low Life-cycle Cost
With redox flow batteries, a larger capacity means better cost advantage. The redox flow battery has a longer life-cycle than other batteries, so there is no need to replace the battery mid-use. It is highly safe and does not require special fire extinguishing equipment.
In addition, since the electrolyte can be reused and recycled, the life cycle cost can be kept low.
5. Easy Operation
In terms of battery operation, ordinary batteries require a complex system to operate, and the amount of charge in each battery varies. In contrast, since the redox flow battery supplies electrolyte to each cell stack from a single tank, the state of charge is the same for all cells, which makes it easy to grasp the remaining charge with accuracy.
6. Flexible Design
The number of cell stacks built into the battery container determines output power, while the amount of electrolyte determines the discharging duration and energy capacity. Since each can be designed independently, you can increase the number of cell stacks for more output or increase the amount of electrolyte by enlarging the electrolyte tank to extend the charging and discharging time with the same output.
