More Energy. More Power.(= superpowers)
Flow batteries are uniquely suited to store large amounts of energy, while simultaneously offering the design flexibility created by separating energy and power. This separation makes flow batteries highly customizable and scalable. More electrolyte can be added for more energy or more electrode can be added for more power. eChemion’s wet chemistry technology focuses on optimizing the graphite materials (e.g. felt, cloth or foil) used in the reactor core.
Flow batteries can store and cycle large amounts of energy, but these reactors will naturally suffer oxidative damage during battery cycling. This oxidation can negatively impact the lifespan of the reactor as well as limit the battery’s operating efficiency.
The eChemion Advantage.(no costume required)
eChemion’s patent-pending "Chemical Stabilization of Graphite Surfaces" technology protects flow battery reactor surfaces from oxidative damage during battery cycling without sacrificing its electro catalytic activity.
Results from accelerated aging tests on both zinc-bromine and all vanadium electrolyte systems, shows our treatment enables reactors to operate for upwards of four times longer with virtually no loss of performance.
Electrode stabilization is provided via simple aqueous chemical treatment of the carbon surface, and could be incorporated into the manufacturing chain either before reactor assembly, or afterwards, allowing treatment of previously assembled batteries. eChemion’s treatment process is very cost effective and inherently scalable.
