<P>PROBLEM TO BE SOLVED: To provide: a positive electrode mixture with which a battery has lower resistance than conventional batteries when the positive electrode mixture is used for the battery; a positive electrode containing the positive electrode mixture; and a battery including the positive electrode. <P>SOLUTION: A positive electrode mixture contains at least two kinds of positive electrode active material particles having an average particle size different from each other. A ratio (V<SB POS="POST">2</SB>/V<SB POS="POST">1</SB>) of a volume V<SB POS="POST">2</SB>of a second positive electrode active material particle having the smallest average particle size to a volume V<SB POS="POST">1</SB>of a first positive electrode active material particle having the largest average particle size is in a range of 0.05-0.2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
