NiMn2O4 (NMO) is a good alternative anode material for lithium-ion battery (LIB) application, due to its superior electrochemical activity. Current research shows that synthesis of NMO via citric acid-based combustion method envisaged application in the LIB, due to its good reversibility and rate performance. Phase purity and crystallinity of the material is controlled by calcination at different temperatures, and its structural properties are investigated by X-ray diffraction (XRD). Composition and oxidation state of NMO are further investigated by X-ray photoelectron spectroscopy (XPS). For LIB application, lithiation delithiation potential and phase transformation of NMO are studied by cyclic voltammetry curve. As an anode material, initially, the average discharge capacity delivered by NMO is 983 mA·h/g at 0.1 A/g. In addition, the NMO electrode delivers an average discharge capacity of 223 mA·h/g after cell cycled at various current densities up to 10 A/g. These results show the potential applications of NMO electrodes for LIBs.

The Sn-Ge metal composite powder was obtained by reduction of the SnGeO3. The XRD and SEM analysis of Sn-Ge were completed. The simulation battery was prepared by using the Sn-Ge as lithium ion battery anode material, and its electrochemical properties were characterized. The results indicate that the SnGeO3 was reduced at 723K to generate the Sn-Ge composite powder instead of the alloy. The first embedding lithium capacity (discharge capacity) was 625 mAh·g-1, the first taking off lithium capacity (charge capacity) was 590 mAh·g-1 for the simulation battery. The capacity gradually decreased with the charge-discharge cycle number increasing, and the discharge capacity corresponded to 88% of the initial discharge capacity, and the charge capacity corresponded to 89% of the initial charge capacity at 20th week. The Sn-Ge composite powder can be used as the lithium ion battery anode material due to possessing embedding / taking off lithium capacity.

Oligomeric Silsesquioxane

Polyhedral oligomeric silsesquioxane (POSS)-derived Si@C anode material is prepared by the copolymerization of octavinyl-polyhedral oligomeric silsesquioxane (octavinyl-POSS) and styrene. Octavinyl-polyhedral oligomeric silsesquioxane has an inorganic core (-Si8O12) and an organic vinyl shell. Carbonization of the core-shell structured organic-inorganic hybrid precursor results in the formation of carbon protected Si-based anode material applicable for lithium ion battery. The initial discharge capacity of the battery based on the as-obtained Si@C material Si reaches 1500 mAh g−1. After 550 charge-discharge cycles, a high capacity of 1430 mAh g−1 was maintained. A combined XRD, XPS and TEM analysis was performed to investigate the variation of the discharge performance during the cycling experiments. The results show that the decrease in discharge capacity in the first few cycles is related to the formation of solid electrolyte interphase (SEI). The subsequent rise in the capacity can be ascribed to the gradual morphology evolution of the anode material and the loss of capacity after long-term cycles is due to the structural pulverization of silicon within the electrode. Our results not only show the high potential of the novel electrode material but also provide insight into the dynamic features of the material during battery cycling, which is useful for the future design of high-performance electrode material.
