Abstract
The invention relates to a tubular electrode for an electrochemical accumulator in the shape of an electrode plate with a number of electrolyte-permeable tube casings essentially parallelly arranged adjacent each other, containing an active material and conductors connected to a common collecting bar.
Claims10
A battery electrode structure comprising:
- a generally planar first electrode;
- a plurality of elongate, permeable tube casings each having a generally oval cross-sectional shape, arranged parallel to one another at an angle to the first electrode of between about 25.degree. and 50.degree., and touching one another along longitudinal contact lines, said angle measured from the major axis of the cross-section of said tube casing;
- a second electrode arranged within each said tube casing;
- and
- an active material substantially filling a volume within said tube casings between said second electrodes and an internal surface of said respective tube casings.
