Physical, and electrochemical behavior of the cathode materials in response to Na+ and K+ ion intercalation is expected to be fundamentally different than the response to Li+ ion. However, there is not much known about how electrochemical reactions and transport of ions take place in cathode materials with different alkali metal ions. First, we will report the utilization of in situ digital image correlation and in-operando XRD techniques to probe dynamic changes in the amorphous phase of iron phosphate during potassium intercalation. A new experimental approach allows to monitor dynamic physical and structural changes in the amorphous phase of the electrodes. Then, we will compare the electrochemical and mechanical response of the iron phosphate cathodes upon Li, Na and K ion intercalation by using electrochemical techniques and in situ digital image correlation.
