Novel Triaxial Raman Scanning Platform for Evaluating Integrity of Graphite Electrodes in Li-Ion Batteries

چکیده
The quality of Li-ion batteries is highly related to the crystallinity graphite used in their electrodes. Therefore, development two-dimensional detection equipment for evaluating integrity electrodes critical. In this study, a triaxial scanning platform was developed Raman spectroscopy. Two-dimensional mapping defects (D band) and stacking (2D performed determine atomic-level variations caused by charging. Through mapping, effects constant-current-constant-voltage (CC-CV) CC-reFLEX fast charging were compared. damage from less extensive than that CC-CV Furthermore, investigations using revealed on curved electrode exhibited disordered after several charging-discharging cycles. This phenomenon creates safety concerns.

In situ scanning tunneling microscopy studies of the SEI formation on graphite electrodes for Li(+)-ion batteries.
The SEI-formation on graphitic electrodes operated as an Li(+)-ion battery anode in a standard 1 M LiPF6 EC/DMC (1 : 1) electrolyte has been studied in situ by EC-STM. Two different modes of in situ study were applied, one, which allowed to follow topographic and crystallographic changes (solvent cointercalation, graphite exfoliation, SEI precipitation on the HOPG basal plane) of the graphite e...
