Heterointerface engineering, especially the construction of heterointerfaces based on two highly active components, is an effective strategy to enhance the sodium storage capacity and accelerate the reaction kinetics of transition metal chalcogenide anodes. Herein, a series of SA-CoFe-S composites composed of two highly active metal sulfides, Co3S4 and Fe7S8, were fabricated through in situ chelation effects coupled with a one-step sulfurization strategy. The optimized SA-CoFe(1:4)-S is composed of fine nanoparticles encapsulated by uniformly distributed S-doped carbon. This unique carbon confinement effect and nano-sized active particles can alleviate volume expansion, shorten the ion diffusion distance, and accelerate electron transfer. In addition, the strong electric-field effect and rich heterointerfaces generated by the heterostructure provide more active sites for sodium storage and accelerate the sodium storage kinetics. The relevant theoretical calculation outcomes further confirm that the heterointerfaces formed between Co3S4 and Fe7S8 can enhance the adsorption energy toward sodium ions and boost the electrical conductivity of the composite material. As an anode material for sodium-ion batteries, the initial discharge/charge capacities were 723/1010 mAh·g−1, exhibited at 1 A·g−1, and the coulombic efficiency (CE) corresponding to this current density was measured to be 71.6%. Even after 800 cycles, the reversible discharge specific capacity of the electrode can still reach 806 mAh·g−1 at 1 A·g−1. Additionally, at an elevated current density of 3 A·g−1, the electrode sustains stable cycling over 500 cycles, with its discharge capacity kept at 258 mAh·g−1 after the long-term cycling test.

As electronic technologies continue to advance, the demand for high-performance and safe batteries has steadily increased. However, silicon-based anode materials experience severe volume expansion and poor structural stability during cycling, which limits their practical application. In this study, we synthesized hollow mesoporous silica to develop an anode material with long-term cycling stability. Electrochemical analysis revealed that the material exhibited low-capacity decay, decreasing from 125 mA·h·g−1 to 120 mA·h·g−1 at a C-rate of 20 C, and retained a 49 mA·h·g−1 after 500 charge–discharge cycles at a C-rate of 10 C. Furthermore, electrochemical impedance spectroscopy and Scanning Electron Microscopy analysis confirmed that the hollow mesoporous silica structure is long-term cycling stability in the anode.

(Bi0.5Na0.5)TiO3-based lead-free ferroelectric ceramics are among the most extensively researched energy storage materials today. In this paper, (1 − x)Bi0.46Sr0.06Na0.5TiO3−xCaTiO3 ceramics were synthesized through a solid-phase sintering method by synergistically adjusting CaTiO3 components after introducing Sr2+ at the A-site. The XRD patterns revealed that all samples formed a single perovskite solid solution, with the 111 and 200 peaks shifting to higher levels as the CaTiO3 increased, indicating a gradual decrease in cell volume. The SEM images exhibited dense crystals without any apparent porosity, which were formed by the different components of the ceramics. Through energy storage, dielectric, and charge–discharge performance tests, it was found that with a 10%mol CaTiO3 addition, the samples obtained a maximum breakdown field strength of 260 kV/cm and corresponding saturation polarization strength of 32.80 μC/cm2 and thereby exhibited a reversible energy storage density valued 3.52 J/cm3. In addition, the dielectric constant varied by less than 10% within the temperature range of 63.7 °C to 132.7 °C and presented good frequency (10–250 Hz) stability at 180 kV/cm. Moreover, the ceramics demonstrated a maximum current density reaching 349.58 A/cm2 and a maximum power density of 18.90 MW/cm3 for their charge–discharge performance, all of which makes them suitable for pulse system applications.
