Product Description

VET ENERGY 5kW Vanadium Redox Flow Battery Stack is a core component for a system designed for high-performance and long-duration energy storage applications. Featuring excellent cycle life, modular scalability, and safety, this stack is ideal for integration in renewable energy systems, commercial ESS solutions, and off-grid applications.


VRFB Stack Structure


A VRFB stack typically consists of multiple repeating units called single cell, each formed by a membrane, bipolar plates, electrode materials, current collector. These cells are clamped together between end plates to form the stack. Electrolyte flows through internal channels, enabling redox reactions that store and release energy efficiently.
