Thin battery with longer life time

Abstract

The present invention relates to a thin battery with longer life time. The thin battery has an anode material and a cathode material applied as pastes on one or more separator paper layers there between. The battery also has an aqueous electrolyte solution, binders and additives. The cathode paste furthermore has conductive material at least partly of carbon nanotubes. The thin battery has an anode material and a cathode material applied as pastes on one or more separator paper layers there between. The battery also has an aqueous electrolyte solution, binders and additives. The cathode paste furthermore has a conductive material at least partly of carbon nanotubes. The conductive material can additionally have one or more other allotropes of carbon, such as carbon powder, e.g. graphite powder.

Description

technical field [0001] The present invention relates to a thin battery comprising an anode material and a cathode material and an electrolyte, the anode material and the cathode material being applied as a slurry on one or more layers of separator paper in between. The cathode paste also includes conductive materials. Background technique [0002] The basic components of a battery are electrodes with terminals connected to an external electrical circuit, separators that keep the electrodes separated and prevent them from short circuiting, an electrolyte that carries charged ions generated due to chemical reactions taking place at the electrodes, and holds the active chemicals and turns the electrodes Keep the enclosure in place. [0003] The chemical reactions that occur in the battery include oxidation and reduction reactions (redox reactions). Batteries fall into two broad categories, liquid batteries (ie, "wet" batteries), in which the electrolyte is liquid or wet, and ...
