ABSTRACT:
The present invention is directed to provide a secondary battery using lithium which includes at least a negative electrode, a positive electrode, a separator provided between said negative electrodes and said positive electrode, and an electrolyte, wherein at least either of said negative electrode or said positive includes an active material having porous hollow structure as a host for intercalating/deintercalating guest lithium ion. The secondary battery shows high electric capacity, high charging/discharging efficiency, high energy density, and long cycle life.
