“…As shown in Figure 5 f, the diffusion coefficients of Mn(OH) 2 nanowire arrays are 4.5 × 10 −8 ~1.0 × 10 −9 cm 2 s −1 and 1.0 × 10 −9 ~2.7 × 10 −11 cm 2 s −1 for charging and discharging processes, respectively, reflecting the rapid ionic diffusion kinetics. Compared with other referenced cathode materials ( Table S1 ), the diffusion coefficients of Mn(OH) 2 nanowire arrays were higher than the Zn 2+ ion diffusion coefficient in MnO 2 [ 16 , 17 , 18 , 19 , 47 , 48 ], V 2 O 5 [ 20 , 21 , 49 , 50 , 51 ] and that in other related materials [ 24 , 25 , 52 ]. The high Zn 2+ ion diffusion coefficients also benefited from the specific configuration in which the vertically aligned arrangement was beneficial to electron transport and the free space between the nanowires, which can provide more ion-diffusion pathways.…”

The morphology, microstructure as well as the orientation of cathodic materials are the key issues when preparing high-performance aqueous zinc-ion batteries (ZIBs). In this paper, binder-free electrode Mn(OH)2 nanowire arrays were facilely synthesized via electrodeposition. The nanowires were aligned vertically on a carbon cloth. The as-prepared Mn(OH)2 nanowire arrays were used as cathode to fabricate rechargeable ZIBs. The vertically aligned configuration is beneficial to electron transport and the free space between the nanowires can provide more ion-diffusion pathways. As a result, Mn(OH)2 nanowire arrays yield a high specific capacitance of 146.3 Ma h g−1 at a current density of 0.5 A g−1. They also demonstrates ultra-high diffusion coefficients of 4.5 × 10−8~1.0 × 10−9 cm2 s−1 during charging and 1.0 × 10−9~2.7 × 10−11 cm−2 s−1 during discharging processes, which are one or two orders of magnitude higher than what is reported in the studies. Furthermore, the rechargeable Zn//Mn(OH)2 battery presents a good capacity retention of 61.1% of the initial value after 400 cycles. This study opens a new avenue to boost the electrochemical kinetics for high-performance aqueous ZIBs.

In this work, experimental characterizations and density functional theory (DFT) calculations were employed to investigate the influence of cations distribution on optical, magnetic, thermoelectric, and electrochemical properties of Li 0.5 Zr 0.5 Mg 0.5 Fe 1.5 O 4 spinel. The crystal structure was successfully refined in the Fd3̅ m space group. It was discovered that a migration between cations occupied the different spinel sites, induced by annealing temperature. The transmission electron microscopy images revealed the formation of the compound of about 34 and 134 nm after annealing at 500 and 900 K, respectively. The DFT calculation and visible−UV measurement proved that the semiconducting behavior of the studied compounds was associated with an increase in the band gap by increasing the annealing temperature. FC/ZFC measurements showed an increase in the Curie temperature from 561 to 598 K after increasing the annealing temperature. Again, we found the presence of a superparamagnetic behavior for the nanometric compound. The thermoelectric properties proved a high merit factor ZT, reaching 0.85. In addition, the efficiency of Li 0.5 Zr 0.5 Mg 0.5 Fe 1.5 O 4 as a cathode for lithium batteries was examined by investigating the discharge process of Li 0.5 Zr 0.5 Mg 0.5 Fe 1.5 O 4 at the early stages of lithiation.

Manganese-based cathodes are promising candidates for aqueous zinc-ion batteries (AZIBs) due to their high-voltage platform, low-price, environmental friendliness, high theoretical capacity, and non-toxicity. Unfortunately, their application is restricted due to issues such as manganese dissolution, poor electrical conductivity, and poor volume expansion, which lead to unsatisfactory rate performance and fast capacity decay. Hollow Mn–Co–O@C yolk–shell microspheres with carbon shells were fabricated from self-assembled Mn–Co-metal–organic frameworks via combining facile normal temperature and annealing methods. Mn–Co–O@C achieved an excellent specific capacity of 401 mA h g–1 and a capacity retention of 94.7% at 2 A g–1 after 2000 cycles. Its remarkable properties are attributed to the hollow structure with high specific surface areas and the mesoporous structure effectively buffering the large volume change which provide additional storage sites and rapid electron/ion transfer. Cobalt doping decelerates the dissolution of Mn2+, so as to maintain good structural stability and improve the specific capacity due to the multielectron redox reaction of cobalt, as well as the carbon coating with high conductivity and thermal stability which can further inhibit the dissolution of manganese. The results indicate that the Mn–Co–O@C hybrid can be a potential cathode for AZIBs.
