Summary: Layered cathode materials, such as LiCoO2, have been synthesized for Li-ion batteries using a direct solution-calcination strategy. The addition of polyvinylpyrrolidone (PVP) as a functional agent in the synthesis process helps to eliminate surface Li residues and promote a uniform particle distribution. The solution-calcined cathode material shows improved cycling stability and rate capability compared to commercial LCO, with suppressed phase transition. This research provides a simple and versatile method for the synthesis of cathode materials, avoiding complicated steps and the formation of unwanted residual lithium compounds.

Summary: This study investigates the application of Prussian blue analogues (PBAs) as electrode materials for aqueous ammonium ion batteries (AAIBs). A PANI/Na0.73Ni[Fe(CN)(6)](0.88) hybrid (PNFF) is synthesized using a covalent bond assisted engineering with in situ polyaniline (PANI) polymerization, combining the high conductivity of PANI and the stability of PBAs. It is found that the PANI content affects the electrochemical performance of PNFF, and an optimized PANI content results in enhanced reversible capacity and cycling stability. The ammonium storage mechanism of PNFF is investigated using in situ Raman and ex situ XPS/FTIR analysis, and a durable aqueous NH4+ full cell is assembled using a polyimide@MXene anode.

Summary: This study focuses on the secondary particles of different Li(NixCoyMnz)O-2 cathodes, investigating the formation and condensation of oxygen vacancies on the surface, as well as the concentration distribution of oxygen vacancies inside the particles after thermal failure. The results show that increasing the Ni content promotes the diffusion of oxygen vacancies from the surface to the bulk, leading to an increase in oxygen vacancy concentration and the release of more oxygen. When the Ni content reaches 0.8, both the surface layer and bulk of the secondary particles exhibit high oxygen vacancy concentrations, resulting in overall failure. Furthermore, the formation and evolution of intergranular cracks inside the secondary particles depend on the oxygen vacancy concentration gradient.

Summary: This study explores the use of aromatic molecules with different ligands as electrolyte additives to improve the chemo-mechanical stability and performance of Zn-ion batteries (ZIBs). Carboxyl and hydroxyl ligands show stronger chemisorption on metallic Zn, while salicylate and catecholate ligands promote efficient solvation based on additive-Zn2+ coordination. Aldehyde and sulfonate ligands enhance the textural growth of the (002) plane due to their lipophilic properties. Sulfonate-based molecules offer the best deposition effect, forming a robust layer with concentration gradients that hinder crack propagation induced by oxidative stress. The addition of sulfonate additives improves the lifetime of Zn-ion batteries from 50 to 3000 cycles. These findings provide a new strategy for the development and optimization of advanced electrolytes for aqueous energy storage.
