Abstract
An electrode comprising a carbonaceous material including carbon fibers, which are bound together by means of carbon atoms. It is preferable that 10-50 w/w % of the carbonaceous material are short carbon fibers 2-20 mm long, which are dispersed and stacked in random directions substantially in a two-dimensional plane and shaped into a plate or sheet, in which the fibers bind to each other by means of carbon atoms to form a carbonaceous electrode. The invention further comprises the method of compressive and electro-osmotic dehydration, wherein direct current is flowed between the electrode, and the polarity is reversed after each predetermined amount of current flow.
