Abstract
A method for forming a connection such as an electrical connection, to a fibre material electrode element comprises moving a length of the fibre 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 fibre material to surround and/or penetrate fibres of the fibre material and form a lug strip in the lug zone. The fibre material may be a carbon fibre material and the lug material a metal such as Pb or a Pb alloy. Apparatus for forming an electrical connection to a fibre material electrode element is also disclosed.

A method for forming a connection to a fibre material electrode element comprising a fibre material, which comprises:
- moving a length of the fibre material continuously or in a stepped movement relative to a pressure injection stage or vice versa;
- and
- by the pressure injection stage pressure impregnating by a series of pressure injection pulses an electrically conductive lug material into a lug zone part of the fibre material during the relative movement between the fibre material and pressure injection stage so that multiple pressure injection pulses inject lug material into different adjacent portions of the fibre material, to surround and/or penetrate fibres of the fibre material and so that the molten lug material impregnating into the fibre material from each new injector pulse merges while molten with the lug material in the fibre material injected at the prior injector pulse to form a continuous lug strip along the 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.
A method for forming a connection to a fibre material electrode element comprising a fibre material, which comprises:
- moving a length of the fibre material continuously or in a stepped movement relative to a pressure injection stage or vice versa;
- compressing the fibre material in the pressure injection stage;
- and
- by the pressure injection stage pressure impregnating by a series of pressure injection pulses an electrically conductive lug material into a lug zone part of the fibre material during the relative movement between the fibre material and pressure injection stage, said compressing of the fibre material in the pressure injection stage to limiting spread of molten lug material across a surface of the fibre material, so that multiple pressure injection pulses inject lug material into different adjacent portions of the fibre material, to surround and/or penetrate fibres of the fibre material and so that the molten lug material impregnating into the fibre material from each new injector pulse merges while molten with the lug material in the fibre material injected at the prior injector pulse to form a continuous lug strip along the 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.
