Lithium-sulfur batteries, rightful predecessors to lithium-ion batteries, are based on the reversible redox reactions between the sulfur-based electrode (cathode) and a lithium metal-based negative electrode (anode) to produce electricity. The new-age batteries have spread their roots in the transport, aerospace, portable electronics, and mining sectors. Thanks to their extended cycle life and relatively lightweight composition, the impact of the lithium-sulfur battery electric vehicle (EV) industry has been undeniable. In May 2023, Stellantis proclaimed an investment in Lyten’s lithium-sulfur EV battery technology. In addition to EVs, Li-S battery technology has the potential to power marine autonomous underwater vehicles, solidifying its reputation as a tool that can be used for deep-sea mining and offshore oil and gas applications.
The world of research is also jumping on the lithium-sulfur juggernaut and exploring the potential prowess of the technology. In October 2023, researchers at Monash University minted a new Li-S battery design that offers an impressive array of advantages over the traditional lithium-ion batteries known to mankind. The new Li-S battery provides a whopping five times the energy of traditional batteries while ringing in at half the cost. Undoubtedly, Li-S is exactly the kind of Holy Grail the world has been looking for.
A new method for energy storage is the need of the hour, and lithium-sulfur batteries have proved their capacities time and again. Their ubiquity and need are only expected to grow with time.
