Battery Materials

Research in the field of energy storage systems has gained huge importance in all sectors of life. Batteries contribute towards the major systems of Energy strorage systems. Improving the cycling capabilities, energy storage capacities, safety and security are the primary aspects which need a deeper understanding of the individual components of the battery i.e., Electrodes and Electrolytes. Presently there is exploding research towards development of new battery chemistries, new nanostructures of the individual components towards meeting the energy storage demands of the world. Therby leading to huge demand for high spatial resolution characterization of such components not only in the as-prepared state but also during various stages of cycling or even after cycling. In all the aforementioned cases, TEM offers a good choice, towards acheiving high spatial resolution. But the expectations of the researchers towards TEM has also been increasing with the advances of in situ electron microscopy, towards understanding the morphological, structural and compositional changes during the process of charging and discharging. For this purpose, the effective dose of the individual components of the battery are pivotal, ignoring which leads to the analysis of electron beam modified components as components of the battery. Thus modifying the complete electrochemistry of the battery. Analysis of individual components of the battery, their beam stability and the critical electron dose under varying imaging techniques become the key parameter. Hence understanding the radiation damage (either Radiolysis, Knock-on-damage or sputtering and heating) leading to either crystallization, amorphization or removal of material remains pivotal. Understanding this thereby leads towards "Better Materials for a Bettery Battery thereby Better Energy Storage System for a Better Tomorrow".
