Flow Battery Basics and Examples

December 25, 2023

Introduction Flow batteries are a type of rechargeable battery that store and release energy through chemical reactions involving liquid electrolytes. Unlike conventional batteries, flow batteries separate the energy storage medium (the electrolytes) and the energy conversion device (the electrochemical cell). This allows for independent scaling of power and energy, as well as long cycle and … More Flow Battery Basics and Examples
