Obtaining Reliable Kinetics from Nanosized Battery Materials

Abstract

One of the many frontiers of energy storage is high power, both on charge and on discharge. Consequently, development of materials that can support high current densities are in vogue. This challenge is here that the mass transport in structures that support ion insertion/dis-insertion is known to be slow. Approaches to address this challenge includes increasing the operational temperature and nanosizing the electroactive active materials. Nanosizing, however leads to severe problems related to obtaining good electronic contact as well as questions regarding the uniformity of the performing across a large population of particles. In this talk we will discuss our recent development of techniques to overcome this these challenges, including techniques that rely on electrochemistry as well as purely chemical ones. Special focus will be given our hyphenated technique providing structural information while providing full charge (disinsertion) in seconds.
