The lithium ion battery chemistries are reaching their theoretical limits. The transition to sustainable energy sources such as solar- and wind power requires large energy storage systems to counter their intermittency. Furthermore, the electrification of the transportation sector increases the demand for higher specific capacities i.e., the capacity to weight ratio. The needs are right

This indispensable attribute is thanks to the lithium-ion battery (LIB) which was first commercialized by Sony and Asahi Kasei in 1991 [i]. Our demand

Hydrogen fuel cells (HFCs) are devices that use hydrogen as a fuel to generate electricity and have great potential for automotive applications and drones. Catalysts are used to power the reactions in the HFC and currently nanotechnology plays a major role in constructing cheaper electrocatalysts. Content What are hydrogen fuel cells?
