STABILIZED LITHIUM METAL POWDER FOR Li-ION APPLICATION AND ANODE

摘要

PROBLEM TO BE SOLVED: To provide a stabilized lithium metal powder having improved air and solvent stability and having a longer storage life; and an anode for a battery using the same.SOLUTION: The present invention provides a lithium metal powder protected by a substantially continuous layer of a polymer. The layer of the polymer is prepared by contacting the lithium metal with the polymer at a temperature between the melting point of the lithium metal and the melting point of the polymer. Such a substantially continuous polymer layer provides improved protection effect compared to, e.g., a lithium metal subjected to typical CO-passivation.
