Understanding the Electrochemical Cycling at Nanoscale in Battery Materials
Link
Research in the field of in situ energy storage systems has gained huge importance in the present decade where batteries, besides being pivotal, also needs improving in their cycling capabilities, energy storage capacities, safety and security which need a deeper understanding of the interfaces of the battery i.e., Anode-Electrolyte and Cathode-Electrolyte. Many research groups around the world try to understand this towards the development of new battery chemistries, new nanostructures of the individual components towards meeting the energy storage demands of the world. TEM, being a high spatial resolution characterization tool enables the understanding of the variations or modifications at the nano-scale. Together with in situ sample holders with continous imaging during any experiment, high spatial resolution involves higher electron doses, increasing the effective dose applied on the system that might lead to radiation damage. Towards understanding the morphological, structural and compositional changes during the process of charging and discharging during an in situ TEM electrochemical cycling experiments, electron microscopists might be misled towards studying the electron beam modified materials and their electrochemical cycling. Effectively the calculation of the critical dose of the individual components of the battery in separate experiments are pivotal. Ignoring this might leads to the analysis of electron beam modified components as components of the battery, thereby studying the electrochemistry of the electron beam modified battery.
