Electrodes for batteries, in particular lithium-ion batteries, and their production

摘要

The method involves depositing a mixture comprising particles of electrochemical active material, a binder, solvent and electrochemical dispersing agent on an electrical conductive substrate e.g. aluminum substrate and copper substrate, where amount of the solvent and/or the dispersing agent is 75-95 weight percent, and amount of the binder is 0.3-2.0 weight percent. Aqueous medium is deposited on the mixture deposited electrical conductive substrate, where the mixture comprises electrode conductivity increasing additive e.g. carbon nanotube, carbon black and metallic additive. The electrical conductive substrate is utilized as a current collector.
