Abstract ：
Understanding the mechanism of oxygen electrocatalysis with sluggish kinetics is important for rationally designing electrocatalysts. Superexchange interaction in transition-metal oxide can regulate the d-band position and effectively enhance catalyst performance. Herein, Magneli oxide V4O7, a type of mixed-valence metal oxide, rich in oxygen vacancies and has good electrical conductivity was chosen as support, and introduced Co into the lattice (CVO), which can effectively improve the performance: the onset potential of ORR was increased effectively (similar to 100 mV), greatly reduced the overpotential (230 mV) with excellent potential gap (0.82 V) of the oxygen electrocatalysis, and enhanced their stability notably. Moreover, the zinc-air cells based on CVO cathode showed about 130 mA cm(-2) in discharge current with 62 mW cm(-2) in power density and 300 h cycle stability. The addition of Co could trigger the Co-O-V active sites through superexchange interaction in the structure of Magneli oxide. This interaction changes electron arrangement of the Co orbitals, advances the positions of Fermi level and d-band centers, moderates the adsorption of intermediates for the oxygen electrocatalytic process. This work provides new insights into catalytic mechanism and rational design of Magneli-oxide-based catalysts and further application.

Abstract ：
The slow kinetics of the oxygen evolution reaction (OER) has limited the development of new energy technologies. Transition-metal spinel oxides have become efficient catalysts owing to their outstanding OER catalytic activities. However, their activity and stability can be low owing to a deficiency of active sites, which needs to be solved. In this study, rare-earth element doping was used to adjust the internal charge redistribution strategy of spinel to significantly improve the OER performance. Pr-doped NiFe2O4 (Pr-NiFe2O4) exhibits an overpotential of 339 mV at a current density of 10 mA cm(-2). In situ Raman spectroscopy and density functional theory calculations indicate that this is attributed to the simultaneous activation of the surface active centers Fe-OOH and Ni-OOH by Pr doping, as Pr can regulate oxygen vacancies and adsorbed oxygen on the surface of catalyst and improve covalent bonding between O 2p and metal 3d orbitals. Moreover, surface valence state analysis and dissolution testing proved that Pr doping inhibits the excessive oxidation and dissolution of transition metals in the catalysts, effectively stabilizing the catalyst after 100 h of CA testing. This study provides a new approach for the design of spinel materials with high OER performances.

Abstract ：
The cathode material of aqueous zinc-ion batteries is a critical constraint on their further application due to the poor structure stability. Consequently, understanding their charge-discharge mechanisms and developing highperformance materials are key to promoting their use. This study investigates the effect of dopant atoms, particularly manganese (Mn), on the properties of vanadium bronze (MVO). Mn, with its larger ionic radius and higher d-electron count, enhanced the electrochemical properties of MVO: the specific capacity is up to 370 mAh/g @100 mA/g and has good rate performance, with a capacity of about 300 mAh/g at 1000 mA/g, a capacity retention rate of 92 % after 2000 cycles and showed the excellent capacity and stability. Mn was present in both the interlayers and within the vanadium bronze structure, promoting the self-adaptive and a more pronounced electron transfer with the metal-oxygen bonds in the structure. This enhanced the covalent character of the metal-oxygen bonds and improved the intrinsic conductivity. The results of in-situ Raman and SQUID measurements revealed changes in Mn-O bond lengths on molecular and atom level and the intrinsic nature of the "pillar effect". These findings provide new insights into ion-doping strategies for enhancing electrochemical performance in zinc-ion batteries.

Abstract ：
Solid polymer electrolytes (SPEs) applied to all-solid-state lithium metal batteries (ASSLMBs) can construct energy storage devices with high safety and high energy density. However, it restricts the application due to the low ionic conductivity and slow lithium transport of SPEs lead the inhomogeneous deposition of Li. Herein, a free-standing SPEs designed by introducing polyether block amide (Pebax) and polyethylene glycol (PEG) as additive to obtain the inspired PP-SPE, which can be prepared at scale. PEG addition helped Pebax connecting to form a network structure. Through the synergistic effect of Li+ and ether oxygen or carbonyl group in Pebax. which promoted the rapid lithium transport and exhibited a high ionic conductivity of 4.27 x 10-4 S cm- 1 (room temperature) and a relative high lithium ion transference number (0.44). In addition, the prepared SPEs had good mechanical properties (5.1 MPa). The highly stable interface with lithium metal was maintained for more than 600 h at a current density of 0.1 mA cm- 2, and no dendrite growth observed. The capacity of the Li//LFP cell was 108 mAh g- 1 at room temperature and 0.5C with 96.5 % capacity retention after 300 cycles. Thus, PPSPE provides a new strategy for the safety and high energy density of commercialization ASSLMBs.

Abstract ：
Understanding the function of individual elements in high -entropy perovskites is one of the critical issues for the design of inexpensive and efficient bifunctional electrocatalysts. Here, we report our findings in boosting the electrochemical activity and durability of a high -entropy perovskite catalyst via sequential substitution of Sr2+ for the A -site elements. According to the Sr2+ localized tuned, the catalyst of (LaSmGdSrPr)0.2MnO3 has a halfwave potential of 0.786 V vs. RHE and an overpotential of 0.378 V and has better ORR and OER electrocatalytic activity than the Sr -free high -entropy perovskite catalyst (LaSmGdYPr)0.2MnO3.This is attributed to the local doping of Sr2+ activating the active center of the high -entropy perovskite catalyst (LaSmGdSrPr)0.2MnO3, modulating the adsorption energy of the oxygen -containing intermediates and the electronic structure of the transition metal at the B -site, which results in efficient oxygen electrocatalytic activity. On the other hand, the introduction of Sr2+ enhances the hybridization between Mn 2p and O 1 s and accelerates the adsorption and desorption kinetics of the intermediates, leading to both enhanced activity and durability of (LaSmGdSrPr)0.2MnO3. DFT theoretical calculations also demonstrate the key role played by Sr2+ in the highentropy perovskite structure for the improvement of the electrocatalytic activity. This study provides new insights for designing high -entropy electrocatalysts for various potential applications.

Abstract ：
Aqueous zinc metal batteries (AZMBs) caught significant attention because of their simple manufacturing processes, low cost, and excellent safety profiles. However, the use of liquid electrolyte in AZMBs would lead to selfcorrosion, hydrogen evolution reaction caused by water decomposition and zinc dendrite growth. These would result in low Coulombic efficiency, poor cycling performance, and cell short-circuiting, limiting the development of AZMBs. Herein, a gel polymer electrolyte (GPE) was designed by introducing polymers of intrinsic microporosity (PIMs) and subjecting the polymer to amidoximation (AO-PIM-1) using bacterial cellulose (BC) as a support membrane to obtain the desired AO-PIM-1/BC GPE. The C=N in the amidoxime functional group in the GPE coordinates with Zn2+ to promote ion transport and uniform deposition of Zn. In addition, the hydrophilic groups, -NH2 and -OH, reduced the energy required for the desolvation of hydrated Zn2+ inducing in a wide electrochemical stability window (2.42 V). Therefore, the Zn//Zn cells that incorporate the AO-PIM-1/BC GPE exhibit a cycle life of up to similar to 1100h and a Coulombic efficiency of 99.97 %. Furthermore, Zn//alpha-MnO2 retains 85 % of its initial capacity after 400 charge/discharge cycles (0.5C) and realizes a dendrite-free Zn anode. This AOPIM-1/BC GPE provides an effective strategy for protecting the Zn anode in AZMBs.

Abstract ：
Fe-N-C has a high number of FeNx active sites and has thus been regarded as a high-performance oxygen reduction reaction (ORR) catalyst, and combining Fe3C with Fe-N-C typically boosts ORR activity. However, the catalytic mechanism remains unknown, limiting further research and development. In this study, a precipitation-solvothermal process was used in conjunction with pyrolysis to produce a series of Fe-N-C catalysts derived from a zeolitic imidazolate framework (ZIF) that was composited with Fe3C. The prepared catalysts had a multiscale structure of ZIF-like carbon particles and rod-like structures, as well as bamboo-like carbon nanotubes (CNTs) and carbon layers wrapped with Fe3C particles while a series of studies revealed the origin of the rod-like structures and Fe3C phase. The hierarchical structure was beneficial to the enhanced electrocatalytic performance of catalysts for ORR. The optimal sample had the highest half-wave potential of 0.878 V vs. RHE, which was higher than that of commercial Pt/C (0.861 V vs. RHE). The ECSA of the optimal sample was 1.08 cm(2) mu g(-1), with an electron transfer number close to 4, and functioning kinetics. The optimal sample exhibited high durability and methanol tolerance for the ORR. Finally, blocking different Fe active sites with coordination ions demonstrated that Fe(ii) was the main active site, indicating that Fe3C primarily served as a cocatalyst to optimize the electron structure of Fe-N-C, thereby synergistically improving the ORR activity.

Abstract ：
Polymers of intrinsic microporosity (PIMs) have been widely used in functional membranes in recent years because of the inefficient packing of molecules to form stable structural micropores. The gel polymer electrolyte (GPE) was fabricated with bacterial cellulose (BC) as support membrane and the partially amidated PIM-1 (named as PIM-CONH2) as functional layer, which was used as electrolyte membrane in lithium-metal batteries (LMBs). Due to the existence of amide groups, the formed PIM-CONH2/BC GPE exhibited a high Li+ transference number (0.76), good cycling performance (83% capacity retention after 200 cycles at 0.5C), and good rate recovery in a LiFePO4|GPE|Li battery. The layered porous structure in the PIM-CONH2/BC GPE could adjust the Li+ transport behavior, and the presence of an amide group promoted the uniform dissolution/ deposition of Li+. And the amidated PIMs in the GPE could play a significant role in improving the interfacial affinity and suppressing the growth of lithium dendrites. This work provides a new strategy for improving the safety and stability of LMBs in order to meet the demands for functionalized LMB electrolytes.
