  • Bipolar battery
    Patent number: 4208473
    Abstract: A secondary bipolar battery including a conductive intercell barrier having a tortuously-pathed (e.g., finned) peripheral portion outboard the cells to reduce parasitic current flow between adjacent cells around the periphery of the barrier. The battery's end electrodes have greater reactant content than the intermediate electrodes to compensate for parasitic losses. A Li/FeS.sub.2 example is detailed.

  • Purification of boron nitride
    Patent number: 4089931
    Abstract: Boron nitride (BN) is freed of boric oxide without increasing its electroconductivity by heating the BN under vacuum to evaporate the boric oxide and chlorinating the BN at a temperature sufficient to remove any elemental boron as boron trichloride.

  • Method of preparing iron disulfide electrodes
    Patent number: 4053978
    Abstract: Iron disulfide electrodes are prepared by: slurrying the FeS.sub.2 in molten sulfur; spreading the slurry into FeS.sub.2 --S sheets; solidifying the FeS.sub.2 --S sheets; sandwiching the FeS.sub.2 --S sheets between porous current-conductor sheets; and heating the thusly formed sandwich to volatize away the sulfur. Flexible FeS.sub.2 --S sheets are obtained by heating the slurry to about 300.degree. C and then rapidly quenching them in H.sub.2 O.
