Operando x-ray liquid-electrochemical microscopy reveals origin of Li charging and discharging of battery primary particles

Lithium iron phosphate (LiFePO4) battery material particles were charged and discharged in-situ while recording the special charge state using STXM (Scanning Transmission X-ray Microscopy) at LBL’s ALS and studied with TEM. This data showed that spatial heterogeneities in reaction rates account for domains with the charging process significantly less uniform than the discharging process. These results highlight the crucial role of surface reaction rate for lithiation, observing these inconsistencies of ion insertion have implications for electrode engineering and battery management for future generation battery technology.

Lithium iron phosphate battery material particles are shown here charging (red to green) and discharging (green to red) in-situ in the X-ray liquid-electrochemical cell. The animation shows regions of faster and slower charge
