STABILIZED LITHIUM POWDER AND LITHIUM ION SECONDARY BATTERY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a stabilized lithium powder capable of promoting doping without generating a defect, such as a crack in an anode and improving an initial charge-discharge efficiency.SOLUTION: The stabilized lithium powder has a stabilized coating on the surface of a lithium particle. The stabilized coating has a peak A having a half value width of 35 cmor less when a peak existing in a range of 1750 cmto 1900 cmin a Raman spectrum is set to the peak A.SELECTED DRAWING: Figure 2
