Batteries charge slowly and degrade over time. This research develops advanced supercapacitors using novel 2D materials and water-based electrolytes. The resulting devices charge rapidly, store five times more energy than conventional supercapacitors, last over 50,000 cycles, and offer a fast, affordable alternative for electric vehicles and energy storage.

This research develops a high-performance supercapacitor using a conductive iron-based metal–organic framework. By overcoming low electrical conductivity, the material enables rapid charging and long cycle life, achieving storage performance three times higher than existing designs. The work advances next-generation energy storage solutions beyond conventional batteries.
