A lithium/fluorinated carbon electrochemical cell having the CFx material supported on a titanium current collector screen sputter coated with a noble metal is described. The gold, iridium, palladium, platinum, rhodium and ruthenium-coated titanium current...

A "fuel gauge" for a pulse dischargeable alkali metal/solid cathode cell is described. The rate of voltage recovery is used to determine the state of charge of the cell. Voltage recovery includes recovery from one load to a second, lighter load, or a loade...

The present invention relates to graphite powder and to a battery using it as a negative electrode material, the powder having a specific surface area of not more than 3 m/g, an aspect ratio of not more than 6, and a tapping bulk density of not less than 0...
