Understanding the effects of different loadings on properties of a silicon/carbon anode for lithium batteries

Si alloy compound. The morphology and difference in electrode expansion of the anode with different Si/C loadings caused by long charge-discharge cycles were analyzed using scanning electron microscopy (SEM). Besides, elemental analysis results indicated that silicon lithium alloying is more prone to oxidation. It is proposed that this work could help provide a basis for the rational design of Si/C pole pieces for lithium batteries.
