NEGATIVE ELECTRODE MATERIAL OF POWER STORAGE DEVICE
Document Type and Number:
Japanese Patent JP2015176676
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power storage device excellent in various performances.SOLUTION: A negative electrode 12 of a power storage device includes a collector 18 and a plurality of particles 22 firmly fixed to the surface of the collector 18. The particles 22 are formed of an Si-based alloy. The alloy contains two or more elements selected from the group consisting of Cr, Al, Sn, Ti, Zr, Hf, V, Nb, Ta, Mo, W, Mn, Fe, Co, Ni, Cu, C, B, P, Ag, Zn, In, Ga, Ge, Pb, Bi, S and Se, with the remainder being Si and inevitable impurities. The alloy contains Cr. The ratio of (Cr%/(Cr%+Ti%+Al%+Sn%+TCF%+TNF%)) is 0.05 or more. The alloy contains Al and/or Sn. The ratio of ((Al%+Sn%)/(Cr%+Ti%+Al%+Sn%+TCF%+TNF%)) is 0.002 or more and 0.400 or less.
