Operating principles

ARIES designs and integrates vanadium batteries and, to complete the scope of its services, has reached a collaboration agreement with companies in the United States and China for LiNMC / G lithium batteries especially suitable for network operation.

In vanadium reduction-oxidation (Redox) flow batteries, nearly 100,000 operating hours have already been achieved, thus demonstrating safety, reliability and efficiency between both technologies.

Virtually unlimited battery life, 25-year warranty.

No need to charge in multiple stages.

Unlimited shelf life (Lead and lithium 5-10 years max.)

Unlimited power sizes with the same power unit by adding more capacity electrolyte storage tanks.

Can be left fully discharged or charged for long periods without ill effects.

If the electrolytes are accidentally mixed, the battery is not permanently damaged.

Tolerates an indefinite number of cycles from 0 to 100% charge or discharge without damage or degradation.

Vanadium Oxide Flow Batteries have the best economic performance and lowest LCOE among commercial Flow Redox batteries.

A single state of charge between the two electrolytes avoids capacity degradation due to a single cell in batteries without flow.

Applications

Microgrids & Residential

Increase the quality and safety of supply from your own system and operate independently of any central grid, reducing cost of energy.
Paneles ARIES Ingenieria

Commercial & Industrial

Energy storage systems facilitate big savings by shifting the time of use to when the energy is more expensive and charging the battery when the grid has the energy at the lowest cost.

Grid quality is vitally important to deliver quality energy and the increasing entrance of renewable power. Particularly solar and wind will produce irregularities that need to be corrected in a fraction of a cycle that can be achieved with the introduction of batteries.

Principle vanadium battery

Principle of vanadium flow batteries

Vanadium flow batteries perform the conversion between electrochemical energy and electrical energy through the electrochemical reaction of vanadium electrolytes of different valences + 2, + 3, + 4, + 5 that circulate in contact with the electrodes.

The electrochemical reaction, the standard electrode potential, and the standard electromotive force are as follows:

  • · Negative: V2+ – e = V3+ E0 = -0.25V (1)
  • · Positive: VO ++2H++e = VO2++H2O E0 = 1.00V (2)
  • · Reaction: V2++VO2++2H+ = V3++VO2++H2O E0 = 1.25V (3)
