ABSTRACT:
A current collector positive electrode enabling a NaS battery to be excellent in the charge recovery characteristic and low in internal resistance is provided, which collector has a high resistance layer formed by needle-punching glass fibers with 5 to 15 μm fiber diameter into a felt substrate made of carbon fibers or graphite fibers by needle-punching from one surface of the substrate toward another surface of the substrate. The density of the glass fibers needle-punched into the substrate is gradually decreased in the direction from the above mentioned surface to the other surface of the substrate, and the deepest portions of the needle-punched glass fibers reach the depths of 85 to 100% of the substrate thickness.
