A method for producing an electrode active coating on a current collector comprising providing isolated lignin and subjecting the isolated lignin to a pre-treatment in order to remove low molecular mass fractions of the lignin. The pre-treated lignin is mixed with an electrode active material, water and a conductive additive material so as obtain a slurry adapted for coating of a current collector. The coating obtained by the method comprises pre-treated lignin as a binder. The coating obtained has good binding properties between the particles of the coating as well as to the current collector. Furthermore, it has excellent electrochemical properties during use in a lithium-ion battery.

Electrode active coating for a lithium-ion battery and method of production therefore

The present invention relates to a process for production of alkali metal chlorate, and to a method of activating a cathode comprising electrolyzing an electrolyte comprising alkali metal chloride in an electrolytic cell in which at least one anode and at least one cathode are arranged wherein a) said electrolyte comprises chromium in any form in an amount ranging from about 0.01-10to about 500-10mol/dmb) said electrolyte comprises molybdenum, tungsten, vanadium, manganese and/or mixtures thereof in any form in a total amount ranging from about 0.1-10mol/dmto about 0.5-10mol/dm.
