EXAMPLE - A first composite casting fluid for an anode was prepared by dispersing octylene carbonate in deionized water under stirring at room temperature, and adding microparticles of TiO2 doped with niobium. Porous zirconia microparticles were prepared by spray-drying. ZrO2 microparticles were coated with PVDF binder. A second composite casting fluid for a separator was prepared similarly. Octylene carbonate was added as a plasticizer to protect the solid components from high shear stress during casting and to get the desirable rheology. The two composite fluids were pumped into a multilayer slot die set and simultaneously casted on a copper current collector laminated on barrier film. The die-casted laminar anode-separator assembly obtained was covered with the high voltage cathode. The stack was pressed for 30 minutes between plates heated at 145degreesC to cure the binder while exposed to vacuum. The precursor cell was then packaged in moisture-impermeable material. The electrolyte was filled in an inert argon atmosphere with a solution of 1.2 M lithium bis-(trifluorosulfonyl) imide in methoxyethoxy propionitrile. Finally, the packaging of the electrochemical cell was sealed. The high safety cell had a nominal voltage of 3.4 V. The battery was able to deliver current at 2C and was recharged at about the same rate.
