Aluminium-Sulfur Batteries: A low-cost Alternative to Lithium-ion Batteries

Long-term energy storage technologies are essential as energy demand grows globally. Due to the limited availability of Lithium, it is now necessary to look for alternatives to Lithium-ion (Li-ion) batteries. The present article describes Aluminium-Sulfur (Al-S) batteries, a powerful contender beyond the Li-ion domain. Both Aluminum and Sulfur are cost-effective and highly abundant elements on Earth. Al-based batteries may have a higher energy density than Li-ion batteries, which are monovalent, due to the triplet of Aluminium. With the increasing demand for electric vehicles (EVs), these batteries can be used at charging stations with the ability to charge faster.
