▎ 摘  要

NOVELTY - A three-dimensional creeper-type high-performance conductive agent comprises sheet-shaped conductive agent, point-shaped conductive agent and linear conductive agent in mass ratio of 0.02-0.025:0.07-0.08:1. The point-shaped conductive agent is in the shape of foot creeper. The linear conductive agent is in the shape of branch diameter of creeper. The sheet-shaped conductive agent is in the shape of the creeper leaves. The high-performance conductive agent is prepared by dispersing sheet-shaped conductive agent, point-shaped conductive agent and linear conductive agent in carboxymethyl cellulose solution. USE - Three-dimensional creeper-type high-performance conductive agent used in electrode for lithium-ion battery (claimed). ADVANTAGE - The high-performance conductive agent has stable structure and excellent conductivity, and is capable of forming a developed effective conductive network and used in low dosage for preparing electrodes, which can effectively increase the energy density of single cell, and improve the positive electrode material of the lithium battery, thereby improving the rate performance and low-temperature performance of the battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of the three-dimensional creeper-type high-performance conductive agent, which involves using the above raw material and 3-8% carboxymethyl cellulose solution; and (2) lithium-ion battery, which comprises positive electrode, negative electrode, separator, electrolyte, and shell. The positive electrode and negative electrode comprises the three-dimensional creeper-type high-performance conductive agent.
