Abstract

As the most successful energy storage system, lithium ion batteries (LIBs) have been utilized in many different fields, such as electric vehicles, smart phones, digital cameras, laptop computers, and so on. Even though enormous efforts have been devoted to improving the performance of these batteries, they still suffer from some intrinsic problems, including poor cycling stability, insufficient rate performance, and active materials aggregation. Therefore, it is important to develop advanced materials with outstanding performance for next-generation batteries. In particular, the anode material, as an important component of the battery, is critical for the improvement of its performance and is currently attracting great research interests. In this thesis, a Ge@N-doped carbon-nanotubes (Ge@N-CNTs) composite with Ge nanoparticles uniformly distributed in the N-CNTs and a yolk-shell Si@carbon composite are synthesized and utilized as promising anode materials for LIBs...
