<P>PROBLEM TO BE SOLVED: To provide a positive electrode material for a nonaqueous electrolyte lithium ion battery, which can suppress a decomposition of an electrolyte even when moisture does not enter a cell and a battery is charged or discharged at high temperature. <P>SOLUTION: The positive electrode material for a nonaqueous electrolyte lithium ion battery includes lithium-nickel oxide having a surface covered with an Li compound to be attached. The Li compound is at least one selected from the group consisting of lithium phosphate, an LiPON compound, an Li<SB POS="POST">2</SB>O-B<SB POS="POST">2</SB>O<SB POS="POST">3</SB>compound, an Li<SB POS="POST">2</SB>O-B<SB POS="POST">2</SB>O<SB POS="POST">3</SB>-LiI compound, an Li<SB POS="POST">2</SB>S-SiS<SB POS="POST">2</SB>compound, an Li<SB POS="POST">2</SB>S-SiS<SB POS="POST">2</SB>-Li<SB POS="POST">3</SB>PO<SB POS="POST">4</SB>compound, lithium hydroxide, lithium fluoride, lithium acetate, lithium acetylide ethylenediamine, lithium benzoate, lithium bromide, lithium carbonate, lithium nitrate, lithium oxalate, lithium pyruvate, lithium stearate, lithium tartrate and lithium sulfate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
