Anode material, anode pole piece, preparation method and application
The invention relates to the technical field of batteries, and particularly discloses an anode material, an anode pole piece, a preparation method and application. The raw materials of the anode material comprise hard carbon, graphite, polyethylene glycol, Li2CO3, phenolic resin and a proper amount of dispersing agent. The anode material is obtained by fusing the hard carbon and the graphite and then carrying out pre-lithiation, carbon coating and spheroidization treatment. The material can be used for improving the low-temperature power performance of the lithium ion battery, can meet the requirements of long service life, low cost and high safety of a high-power system battery, and solves the problem that the battery capacity is reduced due to the fact that most existing electrode materials are easy to polarize in a low-temperature environment; the preparation method provided by the invention is suitable for industrial production, gives play to the performance advantages of the material to the greatest extent, improves the ionic conductivity of the system, prepares the anode pole piece meeting the industrial requirements, improves the low-temperature power performance of the lithium ion battery, and has a wide application prospect.
