The receiver captures these reflected or scattered sound waves and converts them into electrical signals for defect analysis.Ultrasonic waves are highly sensitive to defects and can pinpoint the exact location of defects in two-dimensional imaging, making ultrasound a feasible method for detecting internal defects in batteries.

The defect engineering in CN can narrow the bandgap of CN, thus improving the utilization efficiency for light energy and producing more h + and e −. Although the e − can transfer from the graphene layer to the VB of D-CN, the contribution of h + and OH for photocatalytic degradation is still promoted in contrast to TiO 2 /CN/3DG.
