Abstract
A method for forming a connection such as an electrical connection, to a fiber material electrode element comprises moving a length of the fiber material relative to a pressure injection stage and pressure impregnating by a series of pressure injection pulses a lug material into a lug zone part of the fiber material to surround and/or penetrate fibers of the fiber material and form a lug strip in the lug zone. The fiber material may be a carbon fiber material and the lug material a metal such as Pb or a Pb alloy. Apparatus for forming an electrical connection to a fiber material electrode element is also disclosed.
Claims9
The method for forming an electrical connection to a fibre material electrode element, which comprises:
- moving continuously or in a stepped movement a length of fibre material relative to a pressure injection stage or vice versa;
- and
- by the pressure injection stage pressure impregnating without containing the fibre material in a die an electrically conductive molten lug material into a lug zone part of the fibre material during the relative movement between the fibre material and the pressure injection stage, to surround and/or penetrate fibres of the fibre material and so that the molten lug material newly impregnating into the fibre material merges while molten with the lug material in the fibre material injected immediately prior to form a continuous lug strip of the impregnated material in a lug zone part of the fibre material, said lug zone part of the fibre material having a width transverse to a length of the fibre material less than a greater width of the fibre material.
