Formation and Magnetic Interaction of Si/MnGe Core/Shell Nanowire Arrays

Achieving a Double Advantage Through Design of TiO2/C Interlaced Coating for Si Anode

“…As far as the Si‐based core‐shell structure concerned, it is becoming a competitive type of Si‐based anode. Encapsulating Si with an electronic/ionic conductive shell of high elasticity can release the mechanical strain caused by the huge volumetric change during the de‐/lithiation of Si and hence prevents the devastating electrode cracking [18–23] . Previous researches [24–26] have demonstrated that the mechanical properties of the shell play a vital role in maintaining the architectural stability of the composite electrode.…”

[18][19][20][21][22][23] Previous researches [24][25][26] have demonstrated that the mechanical properties of the shell play a vital role in maintaining the architectural stability of the composite electrode. The shell layer can also protect Si from direct contacting with electrolyte during the cycling process and thus make the electrode more electrochemically stable.…”
