Silicon Anode Materials For Next Generation Lithium-Ion Batteries, Qizheng Li
Electronic Thesis and Dissertation Repository
Lithium Ion Batteries (LIBs) are a promising green energy storage system with application toward portable electronic devices, electronic vehicles (EVs) and smart grid energy storage. High energy density is one of the most important advantages for LIB, however, improvements toward performance measures, such as energy density, power and rate capability, cycling life, safety and cost, need to meet the different requirements for various applications. It is well known that battery performance is highly dependent on the type of electrode material that is employed. Currently most LIBs are predominantly fabricated using graphite as an anode material. Therefore, finding a qualified candidate …
Application Of Molecular Layer Deposition For Graphite Anodes In Lithium-Ion Batteries And Porous Thin-Film Materials, Craig L. Langford
Application Of Molecular Layer Deposition For Graphite Anodes In Lithium-Ion Batteries And Porous Thin-Film Materials, Craig L. Langford
Electronic Thesis and Dissertation Repository
With climate change occurring because of greenhouse gas emissions, the demand for emission free transportation has led to the development of electric vehicles. Improving the batteries’ cycling stability, capacity and safety have been the leading challenges to compete with gasoline and diesel engines. With advances in thin-film deposition techniques via atomic and molecular layer deposition, ultrathin films can be deposited to control the surface chemistry of the battery’s active materials. This thesis aims to understand two main aspects of molecular layer deposition. First, how it can influence solid electrolyte interface formation on the graphite surface during cycling in a lithium-ion …
