Abstract
There is disclosed an improved tubular battery plate comprising a porous envelope enclosing a current collector comprising an array of members extending perpendicularly from an end member which affords a current take off lug with active material disposed between the perpendicular current collector members and the inside face of the porous envelope the ratio of the length of the tubes in cms to the free cross sectional area in sq. cms being in the range 100.1 to 295.1 and the degree of stratification of the active material in the tubes being less than 5%.
Claims3
A lead acid tubular battery plate comprising a porous envelope enclosing a lead or lead alloy current collector comprising an array of members extending perpendicularly from an end member which affords a current take off lug with lead oxide active material disposed between the perpendicular current collector members and the inside face of the porous envelope characterised in that the ratio of the length of the tubes in cms to the free cross sectional area in sq. cms is in the range 100:1 to 295:1 and the degree of stratification of the active material in the tubes is less than 5%.
