How do flow batteries compare to traditional chemical batteries ?
Flow batteries and traditional chemical batteries are both used for energy storage, but differ in aspects such as energy storage mechanism, power and energy density, lifespan and maintenance, and cost and scalability. Traditional chemical batteries store energy through chemical reactions within cells and have a fixed capacity, while flow batteries use external tanks of electrolyte solutions and have adjustable capacity. Traditional chemical batteries can deliver high power output per unit weight or volume and have moderate energy density, while flow batteries typically have lower power density but higher energy density. Traditional chemical batteries have a limited number of charge and discharge cycles before performance degrades and require regular maintenance, while flow batteries can undergo a larger number of cycles without significant degradation and require less maintenance. Traditional chemical batteries often have higher upfront costs and limited scalability, while flow batteries generally have lower upfront costs and offer more flexibility in scaling up. The choice between the two depends on the specific requirements of the energy storage application.
