Effects of Multiple Ion Reactions Based on a CoSe2/MXene Cathode in Aluminum‐Ion Batteries

Abstract: Rechargeable aluminum‐ion batteries (RAIBs) have emerged as a promising battery storage technology owing to their cost‐effectiveness, operational safety, and high energy density. However, their actual capacity is substantially lower than their true capacity and their cycling stability is poor. Therefore, understanding the energy‐storage mechanism may contribute to the successful design of a stable electrode material, on which the performance can be optimized. The aim of this study is to investigate AlCl4− ions… Show more

“…Together with the low CE performance of MoS 2 , it can be inferred that the ion insertion/extraction behavior in MoS 2 has poor reversibility at low current densities, which may be attributed to the structural failure of the host material caused by the strong interaction between the ions and the cathode. 1,36 In the below DFT calculations section, evidence is provided to prove that the serious expansion of lattice volume is caused by ion embedding. The rate capacity of S–MoS 2 reached 214.2, 192.2, 182.2, 166.1, 153.4, and 137.5 mA h g −1 at 0.5, 0.6, 0.7, 0.8, 0.9, and 1.0 A g −1 , respectively, and recovered to 210.2 mA h g −1 when the current density was reverted to 0.5 A g −1 .…”

“…Aluminum batteries (ABs) have attracted increased attention as a new type of energy-storage device owing to the ultrahigh volumetric specific capacity (8056 mA h cm −3 ), abundant natural reserves of aluminum (82 000 ppm), and competitive cost ($2000 per ton). 1–3 At the same time, the high air stability and moderate electrode potential (−1.67 V vs. S.H.E.)…”

“…Here, the Raman peak at 782.0 cm −1 should come from the C−N bonds of PDDA; the Raman peak at 1159 cm −1 should come from the C−O bonds of PVA; the Raman peak at 1367.3 cm −1 should be attributed to the coupling of O−H plane vibration and C−H rocking vibration in PVA; and the Raman peak at 1592.6 cm −1 should be assigned to the G-band of the Ti 3 C 2 nanosheets. 52,53 In addition, the Raman spectra of Ti-PVA/MXene (2) and Ag (0.33)-PVA/MXene (2) were also measured in deionized water. Their Raman peaks were assigned, and the assignments are listed in Table S1.…”

“…In the emerging field of MXene, O, OH, and F groups are widely applied as functionalization groups, [48,82,83] which also leads to significant improvement of voltage as reported in several recent works. [21,80,20,84] This is mainly because a) the surface functionalization elevates the average charge states of metal, primarily through the incorporation of negatively charged ions. This effect is particularly pronounced for surface atoms and naturally leads to an increase in the redox voltage.…”
