Summary: To address the poor conductivity and relatively low capacity of spinel-type lithium titanate (LTO) lithium-ion batteries, an LTO/reduced graphene oxide (rGO)/SnO2 composite is synthesized via in situ electrostatic self-assembly and hydrothermal reduction process. Density functional theory (DFT) simulations show that the introduction of rGO and SnO2 into LTO improves overall conductivity, enhances structural stability, and increases Li-ion diffusion speed.

Summary: In this study, ZIF-67 nanoparticles with a reuleaux tetrahedron morphology were synthesized using a surface-coordinated polymerization method, and nitrogen-doped hollow porous Co3O4 nanoparticles were anchored on reduced graphene oxide to obtain HP-Co3O4/NC@rGO composites. The excellent electrochemical performance of the composite is mainly attributed to the synergistic effect of the hollow nanostructure and graphene network.

Summary: This work investigates the hollow structure that controls the Fe3O4@C void size using a template method to address the issue of large volume expansion during lithiation of iron oxide anode materials in lithium-ion batteries. The hollow structure is controlled by the dosage of ethyl orthosilicate (TEOS), and Fe2O3 is coated with phenolic resin to obtain an anode electrode material with excellent performance. The samples are analyzed for their microstructure and morphology as well as their electrical properties, and the Fe3O4@C-1.0 sample with a large vacancy shows exceptional electrochemical properties, rate performance, and stable cycle performance.

Summary: In this research, a self-supporting binder-free Si electrode with a three-dimensional structure was proposed. The pore structure was adjusted by designing the proportion of carbon nanotubes (CNTs) and carbon nanofibers (CNFs) to alleviate volume change. A stable conductivity network was fabricated using an ice crystal self-assemble freezing technique. The rGO@CNTs@CNFs@Si-2 electrode exhibited a stable electrochemical specific capacity of 2250 mAh/g after 100 cycles (100 mA/g) with good rate capabilities. This simple self-assemble method provides a new route for developing high energy density Si-based electrodes for flexible LIBs.
