▎ 摘　　要

NOVELTY - The electrode has an electrode material layer formed on a current collector. A surface of graphene is formed in the electrode material layer and modified with magnetically responsive nanodots, where 50 wt.% of the graphene is oriented at an angle in specific range with respect to a surface of the current collector on which the electrode material layer is formed to form a heat conduction path with a specific orientation. An inner portion of a battery core material has a fast heat conduction path with a specific orientation such that heat inside the battery core is effectively transmitted outwards to the current collector and transmitted from the current collector to a surrounding environment. USE - Battery electrode for a consumer electronic device. ADVANTAGE - The battery core material inner portion has the fast heat conduction path with the specific orientation such that the heat inside the battery core is effectively transmitted outwards to the current collector and transmitted from the current collector to the surrounding environment, thus conducting the heat generated inside a single battery core from inside to an outer environment in a quick manner to improve battery performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a battery electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a battery electrode.
