  • Chemical prealkaliation of electrodes
    Patent number: 12206087
    Abstract: Disclosed herein are methods of making an electrode. The method includes contacting an electrode material with a mixture that includes an alkali metal, an organic solvent, and an aromatic compound. Also disclosed herein are methods of making a battery that includes an electrode provided by the disclosed methods.
    Type: Grant

  • High discharge rate alkaline battery
    Patent number: 6960409
    Abstract: The present invention provides a primary alkaline battery having a cathode made of porous manganese dioxide, wherein a significant portion of the total pore volume of the manganese dioxide comprises pores which are large. Preferably, at least thirty percent of the total pores of the manganese dioxide are greater than substantially sixty Angstroms. The use of large pore manganese dioxide increases the discharge output and time of the battery, and further decreases manufacturing problems related to die pressing cathode rings from manganese dioxide by reducing the “spring back” or “bounce back” of the manganese dioxide as measured in the die set and after being removed from the die set.

  • Alkaline electrochemical cell having modified graphite additive
    Publication number: 20040234860
    Abstract: An electrochemical cell is provided whose cathode includes a graphite mixture having regular graphite and modified graphite having an average surface area greater than that of the regular graphite. The modified graphite has an aspect ratio greater than or equal to 1.2, and may be present at a concentration less than 25% relative to the graphite mixture.
