Abstract:
A method of assembling an electrochemical cell comprising the steps of:providing a can having a prismatic section with a closed bottom end and an open top end that is circular with a diameter equal to or greater than the maximum inside cross-sectional width of said prismatic section;disposing a cathode through said open top end and into said prismatic section, said cathode having a cavity centrally formed therein and disposed so that said cathode consumes a substantial volume of said prismatic section between said cavity and inner walls of said can;disposing a separator within said cavity;disposing an anode within said separator in said cavity;reducing the size of said open top end of said can to provide a reduced size round open top end; andassembling a cover to said reduced size round open top end.
