dc.description.abstract | The increasing demands for conversionsystems for cleanenergy,wearable devices powered by energy storage systems, and electric vehicleshave greatly promoted the development of innovative current collectorsto replace conventional metal-based foils, including those in multidimensionalforms. In this study, carbon nanotubes (CNTs) with desirable featuresand ease of processing are used in the preparation of floating catalyst-chemicalvapor deposition-derived CNT sheets for potential use as all-aroundcurrent collectors in two representative energy storage devices: batteriesand electrochemical capacitors. Due to their short and multidirectionalelectron pathways and multimodal porous structures, CNT-based currentcollectors enhance ion transport kinetics and provide many ion adsorptionand desorption sites, which are crucial for improving the performanceof batteries and electrochemical capacitors, respectively. By assemblingactivated carbon-CNT cathodes and prelithiated graphite-CNTanodes, high-performance lithium-ion hybrid capacitors (LIHCs) aresuccessfully demonstrated. Briefly, CNT-based LIHCs exhibit 170% largervolumetric capacities, 24% faster rate capabilities, and 21% enhancedcycling stabilities relative to LIHCs based on conventional metalliccurrent collectors. Therefore, CNT-based current collectors are themost promising candidates for replacing currently used metallic materialsand provide a valuable opportunity to possibly redefine the rolesof current collectors. | - |
