Li-ion batteries are state-of-the-art energy storage systems that are being employed in a wide range of rechargeable portable electronic devices and also considered for mass-produced hybrid and electric vehicles. Understanding microstructural aspects of the electrode degradation mechanism during charging and discharging of Li-ion batteries is of key importance in order to design energy efficient batteries with low impedance growth and high capacity. The proposed research program aims at developing advanced characterization methods for identifying the micromechanisms of surface and subsurface damage in negative battery electrodes produced typically from graphite or silicon.
