Characteristics and advantages and disadvantages of vanadium batteries

Vanadium Redox flow Battery (VRB) is a kind of Redox Battery in which the active material flows in a circulating liquid state.

Characteristics of vanadium batteries
Long service life of the system. Vanadium batteries have been charged and discharged more than 100,000 times, and their service life can reach more than 10 years.

System efficiency is high. The cycle efficiency of the vanadium battery system is up to 65-80%.

Support frequent charging and discharging. Vanadium batteries support frequent high-current charge and discharge, which can be achieved hundreds of times a day without causing a loss of battery capacity.

Support over charge and over release. Vanadium battery system supports deep charge and discharge (DOD 80%), deep discharge without damaging the battery.



The charge-discharge speed ratio is 1.5:1.The vanadium battery system can achieve rapid charge and discharge to meet the load needs. Low self-discharge rate. The active substances in the positive and negative electrolyte of vanadium battery are stored in different tanks, and there is no self-discharge phenomenon in the tank when the system is off mode.

Start fast. The charging and discharging switching time of vanadium battery system is less than 1 millisecond.

Flexible battery system design. The power and capacity of the vanadium battery system can be independently designed, configured according to customer requirements and upgraded quickly. Low maintenance cost. Vanadium battery system to achieve automatic operation, low operating cost, long maintenance cycle, easy maintenance.

Environmental protection and no pollution. The vanadium battery system operates in a closed environment at room temperature and meets the environmental requirements. It can be completely recycled without disposal problems.
