With the transition to electric vehicles (EVs), demand for materials used to produce batteries is expected to increase dramatically. Aside from the lithium needed to produce modern lithium-ion batteries, much attention is focused on the cost of the materials used for EV battery cathode production.
Cobalt is an important ingredient in lithium-ion battery cathode production, accounting for about a quarter of the cost of the battery. The price for cobalt spiked to $40 per pound in 2018, but returned to $25 dollars per pound in 2021, while the next most expensive material was nickel at $9 per pound in 2021.
Due to the high cost and price volatility associated with cobalt, battery manufacturers/researchers are seeking alternatives to reduce or eliminate the need for cobalt in battery production.

Former Tesla Battery Expert Leading Lyten Into New Lithium-Sulfur Battery Era — Podcast:
I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
