NOVELTY - Cathode (10) comprises active material layer (a) (12), and another active material layer (b) (15) containing several active material particles (14) sequentially arranged on a collector (11) including several projections (11a) on its surface. Each of active material particles is located on the corresponding projection of collector. The active material layer (a) and active material particles consists of silicon oxide.    USE - Cathode for lithium secondary battery used as power supply for portable information terminal and electronic devices e.g. personal computer and mobile telephone, domestic-use electric power storage apparatus, two-wheeled motor vehicle, electric vehicle and hybrid electric vehicle. Can also be used for non-aqueous electrolyte secondary battery.    ADVANTAGE - The adhesiveness of active material particles and collector is improved by providing active material layer (a). Therefore, peeling of active material particles from the collector is prevented. Since each of active material particles is located on the corresponding projection of collector, the expansion stress can be relieved and deformation of cathode is suppressed. Therefore, lithium secondary battery comprising the cathode has improved cyclic characteristics and high capacitance.    DETAILED DESCRIPTION - Cathode comprises active material layer (a), and active material layer (b) containing several active material particles sequentially arranged on a collector including several projections on its surface. Each of active material particles is located on the corresponding projection of collector. The active material layer (a) and active material particles consists of silicon oxide of formula: SiOx, where x is more than 0 to less than 1. An INDEPENDENT CLAIM is included for manufacture of cathode.    DESCRIPTION OF DRAWING(S) - The drawing shows typical sectional view of cathode.
