Nevertheless, the precise regulation of closed pore structures is significantly impeded by the structural complexity of hard carbon. In this study, a hard carbon with tunable closed-pore architecture was constructed by using ZIF-8-derived porous carbon with uniform pore size (∼0.8 nm) and adjustable pore structure as the substrate. Carbonization temperature control and a chemical vapor deposition (CVD)-based pore-sealing strategy were combined to tailor the pore structure and optimize sodium storage performance. The results revealed that the size and number of closed pores are determined by the open-pore characteristics of the carbon substrate; specifically, substrates with larger micropores and higher specific surface areas promote the development of a greater number of closed pores of larger diameters. Benefiting from the optimized closed-pore architecture, the sample ZCHC-1200 exhibits outstanding electrochemical performance, delivering a high reversible capacity of 436.9 mAh g-1 at 30 mA g-1 with a plateau capacity of 265.0 mAh g-1, and retaining 86.5 % of its initial reversible capacity after 100 cycles. Even at a high current density of 2C, it provides 236.8 mAh g-1. In situ Raman and ex situ X-ray photoelectron spectroscopy (XPS) analyses revealed that the predominant contributor to the elevated plateau capacity is Na+ filling within closed pores.

However, the application of Gr/μm-Si anodes is impeded by the excessive solid electrolyte interphase (SEI) accumulation and electrical disconnection caused by μm-Si swelling and fracturing. Herein, a multifunctional carbon layer (MCL) composed of in situ grown carbon nanotubes (CNTs) and pyrolytic carbon derived from polyacrylonitrile is prepared to optimize Gr/μm-Si anode material. The pyrolytic carbon serves to anchor the CNTs and isolate the μm-Si surface from the electrolyte, mitigating side reactions and ensuring stable SEI formation. The CNTs create a robust three-dimensional conductive network, providing mechanical buffering for μm-Si volume expansion while enhancing electron and ion transport.

However, their lower energy density limits their applications. Ammonium ions (NH4+) have a small hydration radius and light molar mass, and aqueous ammonium ion batteries (AAIBs) are anticipated for solving the inherent low-energy density problem of aqueous batteries. Exploring highly performing storage materials for aqueous ammonium ion batteries continues to be a research hotspot in recent years. Here, we propose a strategy to regulate the tunneling vanadium oxide' structure (VOM) based on the electron-mediated orbital-energy level synergistic strategy of the high-spin 3d transition metal (Mn) to assist AAIBs to achieve high energy density.

At the same time, we demonstrate the chemical energy storage mechanism of hydrogen bonding and the kinetics of interfacial chemical reactions in VOM based on a series of ex-situ or in-situ tests. Density-functional theory (DFT) calculations and experiments demonstrate that the introduction of high-spin transition metals can directionally regulate and optimize the electronic structure of V, which helps to achieve efficient NH4+ storage.

This study addresses this limitation by incorporating selenium (Se) into CFx (denoted as CFx/Se) via a facile low-temperature thermal treatment, significantly enhancing its electrochemical performance. Comprehensive spectroscopic and electrochemical analyses reveal that Se doping induces the formation of CSe bonds, which promote semi-ionic CF bonding, thereby accelerating Li+ diffusion and reducing charge transfer resistance. Density functional theory calculations further demonstrate that Se doping modulates the electronic structure of CFx, narrowing its bandgap to establish an efficient conductive network and markedly improving electronic conductivity. The optimized CFx/Se-1 composite (Se:CFx = 1:9) delivers outstanding performance, achieving a discharge capacity of 383.9 mAh g-1 at a high current density of 20 A g-1 with an energy density of 765.7 Wh kg-1 and a power density of 3.99 × 104 W kg-1.

The synergistic strategy of confinement engineering and heteroatom doping can effectively address these issues. Herein, a composite material of selenium-substituted Bi2S3 (BiSSe) embedded in selenium-substituted sulfurized polyacrylonitrile (SSePAN) is successfully synthesized (denoted as BiSSe-SSePAN).
