METHOD FOR PRODUCTION OF AN ANODE FOR A LITHIUM ION BATTERY

摘要

The invention relates to a method for production of an anode for a lithium ion battery said anode comprising a current collector made from a transition metal M in a sponge form and an active material made from a binary phosphide of said metal M, the active material having the formula MP_x where 1 = x = 4. The method comprises subjecting the metal M sponge to the effect of phosphorous vapours at a temperature of 300 °C to 600 °C, the phosphorous being present in amounts more than ten times different to the stoichiometric amount with relation to the metal M. The invention further relates to an anode for a lithium ion battery and a lithium ion battery with such an anode.
