Vanadium Battery (stack/system)
VRFB battery full name is Vanadium Redox Flow Battery (shorted as
VFB), which is a active substance in liquid state redox batter.
Big Pawer VRFB Battery Division is specialized in vanadium flow
battery energy storage system and its key materials research,development, production, sales, related technical service and
customized solution, which are widely used in field of power grid peak adjustment, solar photovoltaic systems, backup power, energy
storage systems in remote areas, wind energy storage systems,and others.

VFB battery separately stores different valence ions into the
positive and negative tanks. When charge or discharge, through
pump,electrolyte cycles from external tanks into the positive and
negative chamber, and reacts oxidation and reduction at the
electrode surface at the same time, to achieve the battery charge and
Main Technical Parameters
Stack is the VFB battery core part. By integrating, series or
parallel several stacks together, with electrolyte, then it canintegrate larger energy storage system.Our self-developed stack can meet client varied customized needs,
currently finalized models of 1kw / 2kw / 5kw / 10kw / 25kw. Electrolyte is independent, stored in the external tanks, and can
be adjusted by different volume, with following advantages:
Self-technology to produce high purity, high activity vanadium
Finished 5m3/batch electrolyte production line construction
Energy storage system
Vanadium redox flow battery energy storage system is mainly made up
of power unit (stack module), energy storage unit (electrolyte and tanks), electrolyte transmission unit (pipelines, valves, pumps
etc.) and battery management system (pressure, temperature,level monitor unit, charge and discharge device, and control
parts).Features:☆ according to different input grid, can flexible adjust capacity
and stack☆ with over-charge protection, avoid system damage☆ system running real-time monitoring, abnormal alarm☆ remote monitoring, data query☆ With a variety of operating modes, user can achieve one-key
Notice: VFB battery energy storage model can be customized
according to specific requirements, while each kwh increase 50-60L electrolyte.
model selection preference
Energy is stored into the electrolyte, so by increasing electrolyte
volume or improving density, both can increase capacity. That is,
for same power output, the battery system capacity can be adjusted
according to any specific requirements.
