<P>PROBLEM TO BE SOLVED: To provide a lithium ion battery charging and discharging by using Li<SB>2</SB>NiPO<SB>4</SB>F as a positive active material, and also to provide an electrochemical measuring method for examining electrochemical behavior such as charge-discharge characteristics of Li<SB>2</SB>NiPO<SB>4</SB>F. <P>SOLUTION: The positive active material for the lithium ion battery is a material in which part of M of Li<SB>2-x</SB>MPO<SB>4</SB>F (M is Co or Ni; and x=2 to 0) is replaced by one or two or more kinds selected from the group comprising Mg, Al, Ti, V, Mn, Fe, Cu, Zn, Zr, Nb, and Mo, which are different from M. <P>COPYRIGHT: (C)2011,JPO&INPIT |
