In this regard, we review the recent progress in volume-change-accommodating Si electrodes and investigate their ingenious structures with significant improvements in the battery performance, including size-controlled materials, patterned thin films, porous structures, shape-preserving shell designs, and graphene composites.
At the microscopic scale, electrode materials are composed of nano-scale or micron-scale particles. Therefore, the inherent particle properties of electrode materials play the decisive roles in influencing the electrochemical performance of batteries.
This is especially important when considering large-volume-change active materials, as mechanical interactions among contacting particles, as well as overall volume changes of the electrode, can influence connectivity and therefore electrochemical behavior.
Finally, large-volume-change materials also exhibit complex mesoscale interactions within battery electrodes: mechanical interactions between particles, as well as interfacial adhesion characteristics, play more important roles than in traditional materials.
