<P>PROBLEM TO BE SOLVED: To provide a negative electrode plate which can increase battery capacity while enhancing durability thereof, and to provide a lithium ion secondary battery, or the like, with that negative electrode plate. <P>SOLUTION: The negative electrode plate 131 of a lithium ion secondary batter comprises a negative electrode collector plate 132, and a negative electrode active material layer 133 formed thereon. The negative electrode active material layer 133 has negative electrode active material particles 135 which contain a negative electrode active material that occludes lithium ions by reacting thereon to produce an alloy, and are exposed partially on the surface 133h of the negative electrode active material layer 133 in the shape of particles, and a particle holding layers 136 which adheres to the negative electrode collector plate 132 while holding the negative electrode active material particles 135. <P>COPYRIGHT: (C)2012,JPO&INPIT |
