Our research focuses on next-generation technologies made from eco-conscious materials, particularly silicon-air and chloride-ion batteries, which offer multiple times the energy density of current Li-ion systems.

Our research is focused on pioneering post Li-ion battery technologies that leverage sustainable materials to overcome the limitations of existing energy storage systems.

One promising innovation is the alkaline silicon-air battery (SABs), which utilizes abundant, non-toxic Silicium to offer up to 10x the energy density of conventional types. This breakthrough technology presents a powerful, eco-friendly solution for high-performance energy storage. We are also advancing the development of anion-shuttling batteries, particularly room-temperature chloride-ion batteries (CIBs), which use chloride ions instead of lithium. CIBs have a significant potential due to their high theoretical energy density (~2500 Wh/L), making them ideal for a wide range of applications. Unlike lithium, chlorine-based compounds are plentiful and reduce dependence on critical raw materials. Perovskites, with the chemical formula ABX₃, exhibit exceptional properties for battery applications, underscoring the need for focused research to develop perovskite-based electrodes specifically for CIBs.

At JTC, we are overcoming barriers and unlocking the huge potential of sustainable energy storage.
