The invention relates to a accelerating agent of
solid conposite membrane for
lithium cell, which is one millimicron
metal chosen from Ag, Cu, Au, Zn, Fe, Co, Ni, Ru, Rh, Pd, Pt, Ir, Os or Al, or from millimicron
alloy whose expression is MX11MX22...MXnn (M1,M2,...Mn stands for different elements which are chosen from
main group element like Li, or
transition metal like Ag) and at least containing one kind of Ag, Cu, Au, Zn, Fe, Co, Ni, Ru, Rh, Pd, Pt, Ir, Os or Al. The
average size of particles is 0.3~250nm. The accelerating agent deposits on the surface of
electrode, which forms
solid electrolyte membrane with certain flexibility on the surface of
electrode, which forms
solid electrolyte membrane with certain flexibility on the surface of
electrode, greatly increasing service life of
electrode material, making the battery own excellent electrochemical periodicity and property of large
electric current, and reducing the manufacturing cost for electrode, satisfying the requirements of portable electronic apparatus and
discharge and charge of large-powdered battery in electric automobile in the future.
