High performance porous Si@C anodes synthesized by low temperature aluminothermic reaction

Journal Article Mishra, Kuber ; Zheng, Jianming ; Patel, Rajankumar ; ... - Electrochimica Acta

A low temperature (210°C) aluminothermic reduction reaction process has been developed to synthesis porous silicon (Si) as an anode for Li ion battery applications. An eutectic mixture of AlCl3 and ZnCl2 is used as the mediator to reduce the reaction temperature. With carbon pre-coated on the porous SiO2 precursor, porous Si@C core shell structured anodes could be obtained with structure and morphology similar to that of the porous precursor. In addition, carbon coated porous Si also exhibits superior cyclic stability, higher rate performance, and higher coulombic efficiency. The porous Si anode demonstrates a high specific capacity of ~2100 mAh/g atmore »« less

A Novel Approach to Synthesize Micrometer-Sized Porous Silicon as a High Performance Anode for Lithium-Ion Batteries

Journal Article Jia, Haiping ; Zheng, Jianming ; Song, Junhua ; ... - Nano Energy

Porous structured silicon (p-Si) has been recognized as one of the most promising anodes for Li-ion batteries. However, many available methods to synthesize p-Si are difficult to scale up due to their high production cost. Here we introduce a new approach to obtain spherical micrometer-sized silicon with unique porous structure by using a microemulsion of the cost-effective of silica nanoparticles and magnesiothermic reduction method. The spherical micron-sized p-Si particles prepared by this approach consist of highly aligned nano-sized silicon and exhibit a tap density close to that of bulk Si particles. They have demonstrated significantly improved electrochemical stability compared tomore »« less

Facile Synthesis of Micrometer-sized Hierarchical Porous Si@C Anodes for High-Performance Lithium-Ion Batteries

Conference Hou, Xiaodong ; Xu, Shuai ; Sun, Di ; ...

Extensive studies have been conducted to determine if replacing graphite anodes with silicon is feasible since silicon possesses a high capacity and is an abundant resource; however, Si anodes suffer significant volume changes during cycling, which pulverizes its structure and subsequently causes rapid capacity fading. We used SiO2 nanoparticles (nSiO2) and low-cost coal-derived humic acid as a feedstock to synthesize high performance Si-C anodes for Li-ion Batteries through spray drying, calcination, and magnesiothermic reductions. Our Si-C anodes features micrometer-sized porous Si coated with a graphitized carbon shell (mpSi@C). The hierarchical graphitized carbon shell and porous silicon structure relieve the mechanicalmore »« less

A 3D Porous Architecture of Si/graphene Nanocomposite as High-performance Anode Materials for Li-ion Batteries

Journal Article Xin, X ; Zhu, Y ; Zhou, X ; ... - Journal of Materials Chemistry

A 3D porous architecture of Si/graphene nanocomposite has been rationally designed and constructed through a series of controlled chemical processes. In contrast to random mixture of Si nanoparticles and graphene nanosheets, the porous nanoarchitectured composite has superior electrochemical stability because the Si nanoparticles are firmly riveted on the graphene nanosheets through a thin SiO{sub x} layer. The 3D graphene network enhances electrical conductivity, and improves rate performance, demonstrating a superior rate capability over the 2D nanostructure. This 3D porous architecture can deliver a reversible capacity of {approx}900 mA h g{sup -1} with very little fading when the charge rates changemore »« less
