Summary: This article investigates the heterogeneous interface of CoMoO4 center dot 0.69H2O/Co3O4 for oxygen evolution reaction (OER) and finds that the chemically inert Co3O4 support enables the retention of lattice strain in CoMoO4 center dot 0.69H2O, leading to dominant catalytic activity of the reconstructed CoOOH. In situ Raman spectroscopy confirms reversible conversion between active CoOOH and amorphous cobalt oxide during OER with favorable strain, resulting in superior durability and negligible decay after 10 cycles.

Summary: Valence tuning of transition metal oxides is an effective approach to design high-performance catalysts for the oxygen evolution reaction (OER). High-valence oxides (HVOs) exhibit superior OER performance due to charge transfer dynamics and the evolution of intermediates. The filling of e(g)-orbitals and the promotion of charge transfer between the metal d band and oxygen p band enhance the OER performance. Additionally, HVOs utilize lattice oxygen as the redox center in the efficient lattice oxygen-mediated mechanism (LOM), overcoming the scaling limitation of the adsorbate evolution mechanism (AEM).

Summary: This study demonstrates that regulating the chelating power and coordination structure can significantly enhance the high-voltage stability of ether-based electrolytes and the lifespan of lithium metal batteries. The use of 1,3-dimethoxypropane (DMP) and 1,3-diethoxypropane (DEP) as solvents in the electrolytes instead of the traditional 1,2-dimethoxyethane (DME) results in the formation of weak Li solvates, contributing to improved reversibility and high-voltage stability in lithium metal batteries. The fabricated high-voltage Li||LiNi0.8Co0.1Mn0.1O2 lithium metal batteries using 2.30 M Lithiumbisfluorosulfonimide (LiFSI)/DMP electrolyte show excellent capacity retention over 90% after 184 cycles, even under lean electrolyte and low anode to cathode ratio conditions.

Summary: An innovative recycling strategy is proposed to address the excessive chemical consumption and secondary pollution in the wet chemical recycling process of spent LiFePO4 batteries. The strategy involves sustainable proton circulation between organic leachants, extractants, and strippants to regenerate expensive organic leachants and reduce secondary pollutants. Through experiments and analysis, it is found that monocarboxylic acids with low pKa and short carbon chains are effective in leaching lithium from the battery powder. The study also explores direct separation of lithium from organic leachates and successful regeneration of organic acids through proton exchange equilibrium.

Summary: This work investigates the effect of an advanced electrolyte additive on the performance of Ni-rich LiNixCoyMn1-x-yO2/graphite batteries. The results show that the additive induces the formation of robust electrolyte/electrode interphase, significantly improving the cycling performance and reducing the cell impedance. The capacity retention rate of the cells with the additive-based electrolyte can reach 90% after 600 cycles, which is considerably better than that of baseline batteries (70%). Mechanistic studies reveal that the additive suppresses the formation of fragile Li2CO3 and promotes the formation of more stable LiF, LixPOyFz, and additional organic phosphorus species on the electrode surface, thereby preventing cation disorder and irreversible phase transitions.

Summary: Vanadium oxides were reconstructed as advanced cathode materials for AZIBs using a dual-vapour-thermal engineering strategy. The ethanol/water dual-vapour phase triggered the fast formation of oxygen-deficient vanadium oxide hydrates (VPH-VO) with rich bound water pathways, which shielded the electrostatic interaction within the lamellar [VOn] host and facilitated Zn2+ diffusion. The VPH-VO cathode showed outstanding capacity and high-rate cycling stability, making the dual-vapour-thermal engineering an efficient approach for high-performance AZIBs.
