NOVELTY - The battery has electrode plate (10) comprising zirconium plate, electrolytes (46,48) made of bismuth and a separator (20) with a surface. The separator is arranged between the anode and cathode plates. A ceramic dielectric material is permeable to ion flow in combination with carbon and zirconium nanotubes (56). The nanotubes are arranged perpendicular to the surface of the separator and in a direction parallel to the ion flow through the separator.    USE - Secondary battery e.g. lead acid battery.    ADVANTAGE - The long-lasting, high current density charging and discharging temperature-resistant secondary battery can be provided. The carbon and zirconium nanotubes and activated nanosized powder are mixed to manufacture the bismuth electrolyte to facilitate increased ion flow between the anode and the cathode. The electrolytes are confined to the respective independent chambers to prevent contact between electrode plates. The use of zirconium electrode plates provides more durable material to hold ions without deterioration in the chemical reaction. The zirconium electrode plates are corrosion resistant, and can resist high operating temperatures and provide long battery life. The accumulation of dross in the bottom of the battery is prevented so that damage to the battery cell by deep discharging or high charging rates can be reduced. The use of zirconium in sponge or patterned configuration to significantly increase the surface area so as to allow the battery to have increased ion storage capability. The separator is used to prevent the contact between the electrode plates. Thus the electrode plates are prevented from shorting out. The bismuth electrolytes are maintained in the colloidal suspension to prevent the particles from precipitating out of solution. Bismuth colloidal suspension is infused with nanotubes to increase the efficiency of the ion flow between the anode and the cathode and to reduce internal resistance during charging and discharging rates. Electric power storage devices provide rechargeable battery with high current density and high charge/discharge rates. The nanotubes accommodate displacement of positive and negative ions so that the rapid diffusion of ions into and out of the active material can be achieved.
