ABSTRACT:
Electrical cells and batteries having lithium anodes and cathodes comprising an organic slurry of MnO.sub.2 and carbon particles in an organic solvent in contact with a conductive plastic current collector, and a method of making the cathodes comprising the steps of heating MnO.sub.2 to remove absorbed and adsorbed water and water of crystallization, cooling the dehydrated MnO.sub.2, dispersing the cooled and dehydrated MnO.sub.2 in an anhydrous solvent to form a slurry, depositing the slurry in discrete cathode patches on cell component substrates, and sealing the slurry patches into cells having substantially gas impervious cell enveloping boundaries.
