Abstract:
There is provided an electrode for a lithium secondary battery where particles, composed of an active material capable of occluding and releasing lithium, are arranged on a current collector, the active material particle being directly bonded to the surface of the current collector in a state where the bottom of the active material particle is imbedded in a concave portion formed on the surface of the current collector. A second particle layer may be provided on a first particle layer comprising the active material particles directly bonded to the surface of the current collector.
