A highly reliable rechargeable battery comprising an anode, a separator, a cathode, an electrolyte or an electrolyte solution, and a housing, characterized in that said anode is structured to have a size which is greater than that of said cathode. The rechargeable battery provides an increased energy density and has a prolonged charging and discharging cycle life, in which a dendrite causing a reduction in the battery performance, which is generated upon operating charging in the conventional rechargeable battery, is effectively prevented from generating or from growing in the case where it should be generated.
