Vesa Kunnari (Inventor), Otto-Ville Kaukoniemi (Inventor)

    Research output: PatentPatent


    Document discloses new technologies for utilizing cellulose based materials in composites and electrically functionalised structures, such as energy storage devices. The object of the invention is achieved by means of high consistency fibrillated cellulose with at least one functional additive. This high consistency mixture is processed to form the composite structure having a shape and then dried or let to dry.
