The Strucuture Transformation of Silicon Anode Material Induced by Lithium Ion Insertion

Abstract:

Article Preview

Silicon is the most attractive for the largest theoretical insertion capacity of all known host materials except lithium metal. In this paper, the course of lithium insertion into Si material, especially of the first cycle, has been discussed. Anode phase structure, impedance and character, morphology is presented and discussed in this paper. Changes on different crystal lattices revealed the possibility that the structure collapsed firstly began on lattice (220). Distinct crack on the surface of silicon particles has been observed when the anode was discharged to 0.02V.
