Abstract
176,801. VarÚ, E. March 10, 1921, [Convention date]. Electrodes.-A storage battery electrode comprising a conductor surrounded by active material contained in a porous vessel is constructed so that the horizontal sectional area of the active material can be increased to allow for expansion. In one form shown in plan in Fig. 2 a corrugated elastic plate 8 is inserted between the porous vessel 1 and active material 2. In a modified construction the conductor inserted in the active material is hollow and of star shape in section as shown in Fig. 3. Expansion of the active material causes the parts 6, 7 of the conductor to move towards one another. The Specification as open to inspection under Sect. 91 (3) (a) describes other methods of allowing for the expansion of the active material. In one method elastic or plastic bodies of gutta-percha, paraffin or celluloid are placed in the porous vessel. Another method consists in making the active material in the form of hollow granules capable of collapsing under increased pressure, or the active material may contain hollow granules made by cutting up thin-walled metal tubes which form empty spaces into which the active material can expand or which can collapse under increased pressure. This subject-matter does not appear in the Specification as accepted.
