Transition Metal Sulfide Conversion: A Promising Approach to Solid-State Batteries

Rechargeable Li-ion batteries play a critical role in the net zero picture spanning across the automotive industry, grid scale storage, and recycling infrastructure. With the rising demand for lithium-ion batteries in both the electric vehicle and stationary storage sector, challenges regarding resource availability and supply chain are expected. To reduce the inevitable growing pains of the changing global energy storage landscape, other alternative battery materials must be considered. For stationary power sources, the weight and volume requirements are less stringent than their electric vehicle counterparts offering the possibility to look at a wider range of battery chemistries and an opportunity to explore beyond Co- and Ni-based intercalation chemistries. In this Perspective, we explore the opportunity space for all solid-state batteries based on transition metal sulfide conversion chemistries for stationary energy storage applications.
