摘要
The electrochemical reaction in silicon(Si)electrode,accompanying with tremendous volume expansion,causes rapid capacity fade of Li-ion batteries.The Li-ion concentration gradient and structural distribution uniformity influence the inhomogeneous expansion,and the kinetic mechanism of lithiation and interfacial morphology evolvement remains debated.
