Process for preparing a suspension and electrode

The method involves utilizing carbon-based conductive additives and active materials as solid materials such that the carbon-based conductive additives and the active materials are finely simultaneously introduced into liquid by a mixing process and/or a dispersion method under high pressure and/or high shearing forces. Carbon nano-materials such as carbon nano-tubes or a combination of the carbon nano-materials are introduced as the carbon-based conductive additives. An additional additive such as dispersing agent, is brought into the liquid. Independent claims are also included for the following: (1) a method for manufacturing an electrode (2) an electrode.
