Enhanced Structural Integrity and Electrochemical Performance of AlPO₄-Coated MoO₂ Anode Material for Lithium-Ion Batteries

Figure 9

Electrochemical impedance spectroscopy (EIS) data of (a) pristine MoO₂ and (b) AlPO₄-coated MoO₂ with an applied AC signal amplitude of 5 mV peak-to-peak over a frequency range of 1 MHz to 10 mHz. EIS data were obtained after 3 cycles of galvanostatic charge and discharge at room temperature.
