More recently, salt-based batteries are gaining attention. Questions around the supply security of lithium and other Li-ion battery raw materials, drastic price increases linked to insecurity of supply, and sustainability issues around battery raw-materials, drive the search towards alternative battery technologies. Salt would be the ideal raw material for batteries. It is readily available from virtually inexhaustible resources, its production is not subject to sustainability concerns, and it is cheap. Salt-based batteries are gaining particular attention in the rapidly growing segment of stationary energy storage. Renewable electricity sources, i.e., solar and wind are often out of phase with electricity demand, and therefore require intermediate storage capacity to be effectively used. Other than in EV batteries, weight and volume are not critical, and the advantages of salt-based batteries become more important.
In a series of blog-posts, I will take a look at some important aspects of salt-based batteries:
Salt Batteries – Sodium-Ion Batteries – What is the difference?
How do they work? Where are they used? What is their market potential?
How important are salt-based batteries for the salt market at present?
How will this change with the tremendous growth of battery storage capacity over the next years?
