Carbon Nanotubes as Effective Interlayer for High Performance Li-I2Batteries: Long Cycle Life and Superior Rate Performance

Abstract: Highly soluble active materials, such as iodine, are of great potential to develop the research of rapid charge-discharge performance for Li-ion batteries. In this work, a new facile method is applied to construct the iodine/carbon electrode system, which is composed of a thin cathode film, prepared by directly mixing pure commercial iodine and superconducting carbon black, and a carbon nanotubes (CNTs) interlayer. The CNTs interlayer is inserted between pure iodine cathode and separator in the lithium-iodine … Show more

“…As shown in Figure S6, the survey XPS spectrum indicates the presence of C, N, and O elements in CFC@PNCA. Figure e shows the high-resolution C 1s spectrum, demonstrating the existence of the C–N (285.6 eV) bond and the CO bond (287.9 eV) . The presence of oxygen-containing bonds facilitated the nucleation and growth of ZIF-67.…”

“…Figure 3e shows the high-resolution C 1s spectrum, demonstrating the existence of the C−N (285.6 eV) bond and the CO bond (287.9 eV). 13 The presence of oxygen-containing bonds facilitated the nucleation and growth of ZIF-67. Figure 3f shows the high-resolution N 1s spectrum exhibiting the existence of pyridinic N (398.9 eV), pyrrolic N (400.8 eV), and quaternary N (402.4 eV).…”

“…Generally, physical adsorption of microporous material and chemical adsorption of heteroatoms to I 2 molecules are promising strategies for addressing these challenges. 11,15,16,[22][23][24][25] Being an outstanding conductive and porous medium for fast electron transfer and rapid iodine redox reactions, N-graphene, 18 Ti 3 C 2 T x MXene, 27 and carbon nanotubes 28 have been used to fabricate the interlayer for these purposes. Additionally, they can offer large reaction interfaces for the pseudo-capacitive storage in Li-I 2 batteries.…”
