Working principle of the new chlorine flow energy storage battery

Are chlorine (Cl) based batteries a good choice for energy storage?

As an ancient battery system born ≈140 years ago, chlorine (Cl)–based batteries have been actively revisited in recent years, because of their impressive electrochemical performance with the low–cost and sustainable features, making them highly attractive candidates for energy storage applications.

Can a chlorine flow battery be used for stationary energy storage?

“The chlorine flow battery can meet the stringent price and reliability target for stationary energy storage with the inherently low-cost active materials (around $5/kWh) and the highly reversible Cl 2 /Cl − redox reaction,” the research team concluded.

Are flow batteries the future of energy storage?

Realizing decarbonization and sustainable energy supply by the integration of variable renewable energies has become an important direction for energy development. Flow batteries (FBs) are currently one of the most promising technologies for large-scale energy storage. This review aims to provide a comprehen ChemSocRev – Highlights from 2023

What is a solid state chlorine ion battery?

The solid state chlorine-ion batteries have improved the safety of the battery. Not only that, solid-state CIBs generally have a higher energy density because they do not require liquid electrolytes, allowing for greater energy storage efficiency. This allows solid-state CIBs to store more energy in the same volume.

What is a chloride ion battery?

Furthermore, chloride ion batteries (CIBs) based on chloride ions (Cl −) shuttling have raised much attention because of the abundant sources, high energy density, and large potential in large-scale energy storage applications , . As a theoretical prediction, AlCl 3 vs. Mg battery can deliver a specific energy density of 475 mA h g −1 .

When were flow batteries first proposed?

Flow batteries were first proposed in the early 1880s. Since then, they have undergone many developments. Figure 1a illustrates the general configuration of conventional RFBs and basic working principles. RFBs work in a distinctly different fashion to Li-ion batteries.
