High Performance Li4Ti5O12/Si Composite Anodes for Li-Ion Batteries
Improving the energy capacity of spinel Li₄Ti₅O12 (LTO) is very important to utilize it as a high-performance Li-ion battery (LIB) electrode. In this work, LTO/Si composites with different weight ratios were prepared and tested as anodes. The anodic and cathodic peaks from both LTO and silicon were apparent in the composites, indicating that each component was active upon Li⁺ insertion and extr...
متن کاملAdsorption of Li on single-layer silicene for anodes of Li-ion batteries.
We report an investigation of the interactions of Li with silicene. We find silicene to be a promising anode material for high energy density lithium-ion batteries. Based on first-principles calculations, we study the interaction between Li and silicene and explore the microscopic mechanism of Li storage on silicene. We find that Li ion is adsorbed on hollow sites at a very low concentration of...
متن کاملGraphite-Encapsulated Li-Metal Hybrid Anodes for High-Capacity Li Batteries
Graphite has long been the most used commercial anode material in Li-ion batteries. However, it has a limited Li intercalation capacity of 372 mAh g , which cannot meet the increasing energy demand for Li-ion batteries. Here, we propose massive artificial graphite as a host material for the controlled deposition and stripping of Li metal within the internal space of the particles and demonstrat...
متن کاملInterconnected hollow carbon nanospheres for stable lithium metal anodes.
For future applications in portable electronics, electric vehicles and grid storage, batteries with higher energy storage density than existing lithium ion batteries need to be developed. Recent efforts in this direction have focused on high-capacity electrode materials such as lithium metal, silicon and tin as anodes, and sulphur and oxygen as cathodes. Lithium metal would be the optimal choic...
متن کاملComposite Anodes with Silicon and Engineered Graphene for Advanced Li-ion Battery
Introduction Rechargeable batteries with improved energy and power density have many potential, high impact applications including advanced portable electronics and electric vehicles. However, most ‘next-generation’ materials capable of providing improved performance suffer from rapid capacity degradation and severe loss of capacity when rapidly discharged. Architectural design that could succe...
