Abstract
A battery electrode is obtained by a method comprising: mixing active material (A), carbon fibers (B) having a fiber diameter of not less than 50 nm and not more than 300 nm, carbon fibers (C) having a fiber diameter of not less than 5 nm and not more than 40 nm, carbon black (D) and a binder (E) by dry process to obtain a mixture; to the mixture, adding not less than 5/95 and not more than 20/80 of a liquid medium by mass relative to the total mass of the active material (A), the carbon fibers (B), the carbon fibers (C), carbon black (D) and the binder (E); performing kneading while applying shear stress; and shaping the kneaded material into a sheet form.

A method of manufacturing a battery electrode, the method comprising:
- mixing an active material (A), carbon fibers (B) having a fiber diameter of not less than 50 nm and not more than 300 nm, carbon fibers (C) having a fiber diameter of not less than 5 nm and not more than 40 nm, carbon black (D) and a binder (E) by dry process to obtain a mixture,
- adding to the mixture not less than 5/95 and not more than 20/80 of a liquid medium by mass relative to the total mass of the active material (A), the carbon fibers (B), the carbon fibers (C), the carbon black (D) and the binder (E) to obtain a liquid-added mixture,
- kneading the liquid-added mixture to obtain a kneaded material,
- and shaping the kneaded material into a sheet form.
