Flow Battery
Flow batteries circulate electrolytes through an electrochemical cell or stack. In redox-flow systems the active species are stored in external tanks and exchange charge through the cell reactions.
Product & engineering
Understand the product.
A flow battery, or redox flow battery (after reduction–oxidation), is a type of rechargeable battery where recharge ability is provided by two chemical components dissolved in liquids contained within the system and separated by a membrane. Ion exchange (providing flow of electric current) occurs through the membrane while both liquids circulate in their own respective space. Cell voltage is chemically determined by the Nernst equation and ranges, in practical applications, from 1.0 to 2.2 volts. The performance of these devices is governed by the considerations of electrochemical engineering.
Tank inventory influences stored energy, while the stack and operating conditions influence power. Pumping, electrolyte balance and membrane behaviour affect the complete system. Power and energy are related but separately designed.
What turns activity into demand
A longer-duration project can add electrolyte and tank capacity without proportional stack expansion. System value depends on the selected power-energy combination. Separate electrolyte, stacks, balance-of-plant equipment and complete installations. Tank volume is not electrical power capacity.
The commercial boundary
Separate electrolyte, stacks, balance-of-plant equipment and complete installations. Tank volume is not electrical power capacity.
