Optimizing Sn-based Anode Nanostructure and Binder Material for use in High-performance Lithium-ion Batteries

Rechargeable lithium-ion batteries (LIBs), which are the most important electrochemical energy storage devices for small electronic devices and emerging electrical/hybrid vehicles, have been reigning over current rechargeable battery markets due to their high energy densities and great longevity. In recent years, numerous efforts have been made to develop new electrode materials to meet the demand for batteries with higher energy density and enhanced cycling stability. For anode materials, Tin (Sn) serves as a promising alternative to conventional carbonaceous anode active materials due to its ability to react with more lithium ions and achieve higher capacity based on the alloying/de-alloying mechanism. My Master’s work toward the commercialization of Sn anode has been focused on the systematic investigation on this anode material, including the fabrication of ultrafine Sn nanoparticles, exploration of a novel binder, and developing a superior nanostructured configuration of the active material.
