Abstract

The invention discloses a preparation method and an application of a deoxyribonucleic acid (DNA) double-helix carbon nano-fibre and a preparation method of a lithium ion battery anode material. The preparation method of the lithium ion battery anode material comprises the following steps: (1) grinding, namely dissolving a binder into deionized water, fully stirring the binder to obtain a binder solution, grinding the binder solution, a conductive agent and the DNA double-helix carbon nano-fibre in a mortar, and obtaining a sizing agent for smearing; (2) evenly painting a copper foil with the prepared sizing agent and drying the sizing agent; (3) stamping the copper foil into a round electrode plate with a required dimension; and (4) putting the fabricated electrode plate into a battery cathode shell, putting the electrode plate into a vacuum drying oven, drying the electrode plate at 105 DEG C for 8 hours, taking out and weighing the electrode plate, putting the electrode plate into the drying oven again and drying the electrode plate for two hours, so as to obtain the completely dried lithium ion battery anode material. The battery anode material prepared by the method is applied to fabrication of a lithium ion battery; and the comprehensive electrochemical properties of the anode material can be greatly improved.

Description

technical field [0001] The invention relates to the improvement of lithium-ion batteries, specifically a preparation method of DNA double-helical nano-carbon fibers and its application in lithium-ion batteries, and also relates to the preparation of negative electrode materials for lithium-ion batteries, belonging to the technical field of lithium-ion batteries. Background technique [0002] With the widespread application of lithium-ion batteries in the social and economic system, more and more electronic technology products have put forward higher requirements for lithium-ion batteries. At present, the development trend of lithium-ion batteries is: lithium-ion batteries with high energy density, power batteries with high power density, and long-life energy storage batteries. However, the electrode material restricts the performance of the lithium-ion battery. The conductivity of the positive electrode material of the lithium-ion battery is poor, and its conductivity is at ...
