One-pot preparation of La(OH)3 nanoparticles and NiMn LDH nanosheets with mutual support structure as cathode for high-performance aqueous zinc-ion batteries

Recent progress and prospects of rare earth elements for advanced aqueous zinc batteries

“…Moreover, Zou et al pointed out that the addition of RE elements can solve confusion about the poor conductivity of nickel hydroxide (Ni(OH) 2 ) and play a vital role in improving their electrochemical activity. 45 In other words, owing to the intervention of RE elements that leads to the reduction in charge transfer resistance and the improvement in conductivity, the cycle stability and magnification performance of electrodes can be achieved by the introduction of doping RE elements. Finally, the main electrochemical parameters of the previously discussed RE element-doped cathodes are summar-ized in Table 1 for a more intuitive and convenient comparison.…”

Utilization of 2D materials in aqueous zinc ion batteries for safe energy storage devices

“…Moreover, surface reconstruction occurs in the LDHs composites and water molecules within the aqueous electrolyte during the charge/discharge process, which effectively stabilizes H + ions at the electrode-electrolyte interface, facilitating ion diffusion into the cathode, thereby enhancing the overall electrochemical performance. 101 Another strategy for improving the LDHs-based cathode performance is by forming a heterostructure cathode with other 2D materials. Zhang et al demonstrated the formation of 2D heterostructure-based composite cathode using Codoped NiMn-layered double hydroxide (LDH) and V 2 CT x MXene (CNMV), which was successfully fabricated using a simultaneous doping-electrostatic synergistic assembly strategy.…”

“…Despite their susceptibility to water, 2D-MOF was successfully incorporated into AZIBs in 2019, 88 2022, 89 2023, 90 and 2D-COF, with its robust properties, was introduced in AZIBs in 2019, 91 2022, 92,93 and 2023. 94 Lastly, LDH has been adopted since 2014 95 and has been gaining significant attention in recent years (2022, [96][97][98][99][100][101] 2023 102 ). When considering anode for AZIBs, numerous 2D materials such as graphene (2018, 13 2019, 103 2020, 104 2021, [105][106][107][108][109] 2022, [110][111][112][113] 2023 114 ), MoS 2 (2020 115 ), g-CN (2021 116 ), BN (2022 117 ), MXene (2019, 118 2020, 119 2021, 109,120-122 2022 123 ), and 2D-MOF (2022 124 ) have been exploited on the anodic side to address existing challenges, including dendrite formation, HER, OER, and corrosion.…”

Direct Atomic-Scale Insight into the Precipitation Formation at the Lanthanum Hydroxide Nanoparticle/Solution Interface

“…This limitation is especially prevalent for metal (hydro)­oxide , including compounds of iron, aluminum, , zinc, molybdenum, vanadium, and cerium . Lanthanum hydroxide [La­(OH) 3 ] is a representative metal hydroxide used in catalysis, environmental remediation, and electrochemical energy storage applications. , In particular, it is now frequently used for efficiently scavenging anionic pollutants even at trace levels. − These processes may produce surface precipitation, which are typical of a number of reactions at solid surface, such as heavy metal fixation, silicate weathering, organic matter burial, and ferrous sulfide formation in sediments . A few recent studies reveal that La­(OH) 3 crystallinity might exert a critical influence on the interfacial interaction of La­(OH) 3 with anionic pollutants .…”
