A highly reliable rechargeable battery comprising an anode, a cathode, a separator positioned between said anode and said cathode, and an electrolyte or an electrolyte solution disposed so as to contact with said anode and said cathode, wherein said anode comprises an electrically conductive material, and said electrically conductive material is provided with an insulating or semiconductor film such that at least protrusions present at said electrically conductive material are covered by said insulating or semiconductor film while forming an opening between adjacent protrusions such that said opening is communicated with said electrically conductive material of said anode and said electrically conductive material of said anode contacts with said electrolyte or said electrolyte solution through said opening. The rechargeable battery is of an increased capacity and it provides an increased energy density and has a prolonged charging and discharging cycle life, in which the generation or growth of a dendrite of lithium or zinc is effectively prevented.
