A high-power lithium-ion hybrid capacitor based on a hollow N-doped carbon nanobox anode and its porous analogue cathode

Abstract

A novel “dual carbon” lithium-ion hybrid capacitor configuration is designed by using an anode of a hollow nitrogen-doped carbon nanobox and its porous analogue cathode.

Matched Facet‐Induced Microflower‐Like Li, Ni‐Codoped Zn3V3O8/V2O3 Nanoplate Assemblies Grown on Bamboo‐Like Carbon Nanotube for High Energy Density Lithium‐Ion Capacitors

“…This ultrahigh energy and power performance of the LNZVO@C//FBCNT LIC is superior to those of most of the previously reported LICs (Table S4, Supporting Information). [ 6,7,11,40–43 ] Meanwhile, the potential application of the LNZVO@C//FBCNT LIC was demonstrated by using a group of eight light‐emitting diodes (LEDs) system, which could be powered by this device (Figure 9f, inset). The results show that LNZVO@C//FBCNT LIC can realize high‐voltage output and outstanding energy storage capability.…”

“…[ 5 ] So, one major challenge in the field of LIC is to search suitable electrode materials to overcome the energy storage dynamic imbalance between cathode and anode. [ 6,7 ]…”

Recent Advances in Alkali Metal‐Ion Hybrid Supercapacitors

“…When graphite is utilized as the anode for AMHSs, it is usually doped with heteroatoms [44–64] . For example, pre‐lithiated graphite was fabricated as anodes by Sivakkumar et al ., [38] which was assembled with AC cathodes.…”

Li4Ti5O12−TiO2 Composite Coated on Carbon Foam as Anode Material for Lithium Ion Capacitors: Evaluation of Rate Performance and Self‐Discharge

“…[12][13][14] Therefore, lithium ion capacitors (LICs), which combine the high rate capacity of non-faradaic SCs and high energy density inherent to batteries, have emerged recently and attracted much attention. [15][16][17][18][19][20][21][22][23][24][25][26] Li 4 Ti 5 O 12 (LTO) is a promising anode material which can be combined with activated carbon (AC) cathode for LICs because LTO has high columbic efficiency, zero-strain insertion of Li + ions, little electrolyte decomposition, and low cost. [27][28][29] However, LTO suffers from low rate capability due to its poor Li + diffusion coefficient (< 10 À 6 cm 2 s À 1 ) [30] and low electronic conductivity (< 10 -13 S cm À 1 ).…”

“…While LIBs have high energy densities but suffer from low power density and limited cycle life, SCs offer excellent power performance and long cycle life but their energy densities should be much improved . Therefore, lithium ion capacitors (LICs), which combine the high rate capacity of non‐faradaic SCs and high energy density inherent to batteries, have emerged recently and attracted much attention …”
