  • Rechargeable battery cell with improved high temperature performance
    Patent number: 9425456
    Abstract: An alkaline, rechargeable electrochemical cell includes a pasted electrode structure in which a composition comprising a paste matrix component includes cobalt in an amount greater than 6 weight percent ranging up to 14 weight percent. The matrix may also include a rare earth such as yttrium. The composition further includes particles of nickel hydroxide dispersed in the matrix, and these particles include cobalt levels ranging from greater than 8 atomic percent up to 15 atomic percent. Cells incorporating these materials have good charging efficiency at elevated temperatures.
    Type: Grant
    Filed: February 6, 2013
    Date of Patent: August 23, 2016
    Assignee: Ovonic Battery Company, Inc.
    Inventors: John M. Koch, Cristian Fierro
