Fabricating ZnO@C composites based on shell-derived cellulose for high performance lithium-ion battery anodes.

In this study, shell-derived cellulose was successfully produced, and the hydrothermal method was employed to generate ZnO@C (ZOC) composites, which were then subjected to calcination in N gas at a temperature of 600 °C for varying durations. X-ray diffraction and thermogravimetric analyses demonstrated that the annealing duration had a substantial impact on the quantities of C and ZnO in the ZOC composites. The scanning electron microscope images indicated the presence of ZnO nanoparticles on the surface of the C phase and revealed a similar morphology among the ZOC composites.

Tailored synthesis of NdMnFeO perovskite nanoparticles with oxygen-vacancy defects for lithium-ion battery anodes.

In this study, we synthesize nanostructured NdMnFeO perovskites using a facile method to produce materials for the high-working-efficiency anodes of Li-ion batteries. A series of characterization assessments (e.g.

Electrochemical Performance of Sn/SnO/Ni3Sn Composite Anodes for Lithium-Ion Batteries.

We have synthesized a novel composite material Sn/SnO/Ni₃Sn via galvanic replacement reaction between Sn and Ni ions in triethylene glycol medium and at high temperature. The reaction time affected structure, particle size, and composition of Sn/SnO/Ni₃Sn composites, which were analyzed by high resolution transmission electron microscopy, energy dispersive X-ray spectroscopy, and X-ray diffraction. The active component (Sn) reacts with Li ions while inactive component (Ni) acts as a metal framework to support the electrochemically active Sn, a buffer to reduce volume change during cycling, and the electron conductor.
