IFBs are a type of redox flow battery that uses iron as the active material for both the positive and negative electrolytes. The technology leverages reversible oxidation and reduction reactions of iron to store and release energy. Our batteries are characterized by their safe, non-toxic, and water-based chemistry, making them ideal for stationary energy storage applications.
IFBs have a significantly longer lifespan than lithium-ion batteries because they do not suffer from electrode degradation or capacity fade over time. The use of aqueous electrolytes and mainly galvanic process for charging means the electrochemical reactions occur without damaging electrodes structure. Typical IFBs can last 20+ years with minimal performance loss, whereas lithium-ion batteries degrade after 10,000 cycles.
Cost-effectiveness. Low-cost raw materials like iron and water make IFBs affordable.
Scalability. Power (stack) and energy (electrolyte volume) are independently scalable, allowing for customizable configurations.
Safety. Non-flammable, non-toxic electrolyte ensures operational safety.
Durability. Over 20 years of operation without degradation or replacement.
Sustainability. Iron is abundant and recyclable, making IFBs an environmentally friendly option.
IFBs are highly effective at managing variable renewable energy inputs due to their flexible and fast response times. They can store excess energy during periods of high production (e.g., sunny or windy hours) and release it during peak demand. The technology supports smooth grid integration by balancing supply and demand, ensuring stability and reliability.
IFBs require minimal maintenance because their design avoids degradation-prone components like solid electrodes. The primary maintenance involves occasional electrolyte checks and monitoring of system components like pumps and sensors.
IFBs are environmentally friendly. The electrolyte is water-based and non-toxic, posing no significant environmental risks. Unlike lithium-ion batteries, which require careful handling and recycling of hazardous materials, IFBs use iron, an abundant and recyclable material, ensuring minimal ecological impact during manufacturing and disposal.
