Abstract
The invention concerns a method for manufacturing of a battery electrode material comprising the steps of: a) applying an electric field to at least one polymer, conductive particles and at least one solvent whereby said conductive particles become arranged between the electrodes in at least two lines that are oriented in the same direction as the electric field line, and b) stabilizing the at least one polymer, conductive particles and at least one solvent by removing at least some of said at least one solvent while maintaining the electric field in step a) whereby the at least two lines of conductive particles will remain in their position when said electric field is removed. Further, the invention concerns a battery electrode material comprising at least one polymer and conductive particles, wherein said conductive particles form at least two lines that are oriented parallel and/or co-linear to each other.
