Abstract

The advent of hybrid battery-supercapacitor devices (HBSDs) represents a significant advancement in energy storage technology, combining the high energy density characteristic of batteries with the superior power density and extended cycle life of supercapacitors. Among the various cathode materials being investigated for these HBSDs, nickel-cobalt-manganese (NCM)-based cathodes have attracted much attention due to their high capacity, excellent rate capability, and relatively low cost. This mini-review discusses the fundamental properties of NCM materials, their electrochemical performance, and strategies to improve their performance. In addition, the article highlights the challenges and future prospects for the development of NCM-based cathodes in hybrid energy storage devices.
