<P>PROBLEM TO BE SOLVED: To provide a battery having high capacity, in relation to a lithium battery using manganese dioxide for a positive electrode and lithium for a negative electrode. <P>SOLUTION: This positive electrode for a battery comprising a collector and single-crystal manganese dioxide particles being an active material is characterized in that the c-axis direction of the single-crystal manganese dioxide particles is oriented vertically to the collector, and is improved in discharge characteristics by improving diffusion of lithium ions in active material particles by increasing the fill of manganese dioxide in the battery. <P>COPYRIGHT: (C)2007,JPO&INPIT |
