Experimental Approaches Toward Understanding Productive Electrochemically Induced Conversion Processes Within Battery Electrodes

In intercalation materials, the kinetics and uniformity of mass transport across the nanocrystalline domains dictate the structural reversibility and transport capability at the macroscopic level. Conversion materials which undergo more significant changes of state and/or phase upon electrochemical redox bring added challenges for phase identification at the interface and prediction of resultant electrochemical behavior at the systems level. Recent advances in advanced characterization toward understanding productive electrochemically induced conversion processes within battery electrodes will be described in this presentation, including the benefit of complementary in-situ and operando techniques.
