Requirements of electrolytes In a flow battery, the electrolytes serve as the working solution carrying redox active substances, some vital parameters such as open circuit voltage (OCV), conductivity, viscosity, concentration, etc. will have great impacts on the battery.
Some technologies are more affected and others less. Flow batteries have the advantage, that only the electrolyte which is located inside the stacks may be affected by such processes when pumps are stopped. The remaining electrolyte volume inside of the external tanks, is not affected at all.
Considering the distribution of volumes of typical flow batteries between volume in stacks and volume in tanks, then most often the potential volume for discharge is far less than 1%. Flow batteries may vary inside their own technology community but usually they work in ambient temperature ranges.
This technology strategy assessment on flow batteries, released as part of the Long-Duration Storage Shot, contains the findings from the Storage Innovations (SI) 2030 strategic initiative.
In the view of experts, flow batteries are feasible for large energy storages. This can be interpreted in two ways. One is the storage of large amounts of energy and the other is to be able to discharge the nominal energy for a longer time period.
Flow batteries offer a new freedom in the design of energy handling. The flow battery concept permits to adjust electrical power and stored energy capacity independently. This is advantageous because by adjusting power and capacity to the desired needs the costs of the storage system can be decreased.
