Failure analysis of commercial silicon materials for lithium-ion batteries
Silicon-based materials have been extensively studied as the typical representation of high capacity anode materials in lithium ion batteries.Here,we showed electrochemical performances of three kinds of commercial silicon by cyclic voltammogram (CV) and galvanostatic charge/discharge cycling.Scanning electron microscopy (SEM) and energy dispersive X-ray detector (EDX) were used to determine the microstructure and composition.Electrochemical impedance spectra (EIS)reveal the possible reasons of unsatisfactory electrochemical property.The prospects for high energy density lithium ion batteries anode materials were also discussed.The feasible research methods for the silicon based anode materials have been summarized.The new material for lithium-ion batteries would be promising if some problems can be solved.
