As a result, the silicon-carbon anode with the optimized electrolyte exhibits excellent cycling and rate performance, and can work reversibly with a high capacity of 1709.1 mAh g-1 that proceeds for over 250 cy
anode in which sintering of Si leads to the transformation of micro-metre particles into dense continuum. A 3D ionic-electronic-conductive network composed of plastically deformable Li-rich phases (Li15Si4and LiC6) that enlarges active area and relieves stress concentration is created in the anode...
The synthesis of nano-sized Si with various microstructures has been studied intensively to produce anode materials for Li-rechargeable batteries. Methods such as chemical/physical vapor deposition (CVD/PVD) and wet-chemical processes are currently used to produce nano-sized Si; however, the ...
Overall, this Perspective gives an insight into the potential future direction for the development of the Si anode and the evaluation of new Si anodes to ensure the enhancement of volumetric energy density and cycle life in the full cell. Summary Over 20 years, Si has been investigated as a ...

Lithiation of the Si anode begins with the reaction at the interface between the unreacted c-Si and reacted region15. Since the diffusion behavior of the Si anode is determined by the characteristics of the interfacial reaction, a simulation technique that can resolve the interfacial reaction occur...
