Hence, the stable SEI layer could prevent the continuous side reactions between anodes and electrolyte. Moreover, the evenly introduced CNT nano-skeleton structure can improve the distribution of conductivity pathways in Si-SiOx@C-1.25 as shown in CAFM (Fig. ). The homogenous electric contact of particles in Si-SiOx@C-1.25 with electrolyte can promote the formation of thin and compact SEI layer . ) . In the equation, b value is used to determine the Li + -diffusion controlled behavior when b=0.5 and pseudocapacitivecontrolled behavior when b=1 . For Si-SiOx@C-1.25, the obtained b values for anodic peak (peak 1) and cathodic peak (peak 2) are 0.90 and 0.70, respectively, indicating the mixed Li + storage process (Fig. ). Also, the fractions of diffusioncontrolled and pseudocapacitive-controlled processes can be identified from the current (i) at a specific potential (V), based on the following equations:
