Recent Advances on Carbon‐Based Materials for High Performance Lithium‐Ion Capacitors

Abstract

Lithium‐ion capacitors (LICs) combining of lithium‐ion batteries (LIBs) and supercapacitors (SCs) with improved performance bridge the gap between these two devices, and have attracted huge attention in the field of high‐efficiency electrochemical energy storage. The behavior of electrode materials is essential for the realization of high energy and high output LICs devices. As the most widely utilized electrodes, carbon materials demonstrated their ability in LICs with fast charge storage and long life‐span. Here, an overview of carbon materials for advanced LICs applications is given. The advantages and shortcomings of carbon materials as electrodes are systematically analyzed with the purpose of disclosing their influence on LICs devices. In light of this analysis, the critical aspects are discussed, which should be dealt with in the future for the realization of desires high‐performance LICs devices.

Nitrogen and phosphorous co-doped hierarchical meso—microporous carbon nanospheres with extraordinary lithium storage for high-performance lithium-ion capacitors

“…Compared with well-studied activated carbon cathodes, anode materials with a high specific capacity, good rate capability, and long-term cycle stability have been the focus of research. To date, various anode materials have been explored to promote the development of LICs, mainly including alloy-, redox-, and insert-type materials [3]. Alloy-and redox-type electrode materials possess high specific capacity, but they suffer from large volume change and poor cycle stability [4].…”

3D Printed Supercapacitor: Techniques, Materials, Designs, and Applications

“…Although these carbon‐based materials mentioned above show high power density and cycle stability, there are still some limitations in practical applications because of their relatively low charge storage capacitance. [ 94 ] Pseudocapacitive materials, including transition metal oxides, transition metal hydroxides, and conducting polymers have higher capacitance but usually inferior rate performance. [ 86a ] On this basis, it will be an ideal choice to combine pseudocapacitive materials with EDLC materials to prepare composite electrodes with higher comprehensive electrochemical performance.…”

Recent Advances in Interface Engineering and Architecture Design of Air-Stable and Water-Resistant Lithium Metal Anodes

“…Carbon nanomaterials are considered as ideal lithium deposition carriers because of their lightweight, robust electrical conductivity, high mechanical flexibility, good electrochemical stability, and low cost. − The theoretical specific capacity of graphite anode is much lower than that of LMAs, so much attention is focused on the development of lithium/carbon-based composite electrodes. In this regard, lithiophilic materials such as porous carbon nanofibers, graphene, and graphene oxide are acknowledged to be the main materials of composite lithium anodes. − Typically, the carbon nanotube (CNT) has good thermal and mechanical properties, as well as good electrical conductivity, and Li-CNT composites have good dendrite inhibition property and high specific capacity. , However, because of its small size, the composites have high activity, leading to severe spontaneous combustion even in dry air. , To address this issue, the lithium/carbon composite anode containing fluorocarbon nanotubes (Li/FCNT, only 1.6 wt %) was prepared by the melting-impregnation method and had significantly enhanced chemical and electrochemical stability compared to lithium metal.…”
