Summary: In this study, an aqueous binder called PGA-ECH was used to enhance the performance of SiOx anodes, improving long-term cycling stability. The binder's structure contains abundant functional groups that form strong interactions with the SiOx surface, ensuring good interfacial adhesion. Covalent bonds and supramolecular interactions in the binder guarantee mechanical strength and elasticity. The interactions between lithium ions and the oxygen (nitrogen) atoms of carboxylate (peptide) bonds facilitate the diffusion of lithium ions.

Summary: In order to pursue sustainable developments, this study investigates the application of poly(N-vinylformamide) (PNVF) as a green, bio-derived and water-soluble binder for Li4Ti5O12 (LTO) anode in lithium-ion batteries (LIBs). The electrochemical performance differences between PNVF electrodes and conventional polyvinylidene fluoride (PVDF) electrodes are presented. The results demonstrate that the electrode with 3 wt% PNVF shows higher peeling force and better cycle performance compared to the one with 10 wt% PVDF. Additionally, the optimal PNVF electrode exhibits lower electrochemical impedance and higher lithium-ion diffusion coefficient.

Summary: Long-term cycling performance remains a crucial challenge for Si-based full cells due to the instability of Si surface. A solid interfacial conversion between cryolite (NAF) and SiOx layer on the Si surface forms a robust and corrosion-resistant interfacial layer. The optimized Si@NAF-C350 anode demonstrates improved electro-chemical properties and delivers a reversible capacity of 1387.4 mAh g 1 after 500 cycles. The full cell based on this Si anode exhibits a significant cycling enhancement and achieves a high reversible capacity of 133.8 mAh g 1 after 300 cycles, demonstrating the feasibility of practical application.

Summary: This study developed a novel inorganic binder, lithium metasilicate (LS), to address the issues of volume variation and limited Li+ diffusion ability in silicon anodes. The LS binder showed favorable compatibility with silicon nanoparticles (SiNPs) and improved the cycling stability and discharge capacity of the silicon anode through strong adhesion effect. The presence of Li+ transport channel within the LS binder further enhanced the Li+ diffusion ability in the silicon anode, resulting in higher discharge capacity.

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.
