Abstract

Electrochemical storage has gained momentum amid increasing concerns for a cleaner, more environmentally friendly future. Currently, lithium ion battery systems do not meet the requirements to quell the increasing concerns and it is therefore imperative to move in a new direction. Top contenders for ‘beyond lithium’ is lithium-sulfur (Li-S) and silicon (Si) and other various metal oxides. In order for these materials to be adopted, it is necessary to use alternative methods of synthesis, varying architectures, and different approaches to formation. Herein, different methods for improving sulfur, silicon, and nickel oxide capacity, rate capability, and longevity will be explored using electrochemical and physical characterization.
