Abstract

The invention discloses a method for preparing a sodium-ion battery electrode carbon material from anredera cordifolia. The method comprises steps as follows: step 1, the anredera cordifolia is dried after being washed with ethanol and deionized water; step 2, the dried anredera cordifolia is placed in a high-temperature furnace for carbonization, and anredera cordifolia derived carbon is obtained; step 3, the anredera cordifolia derived carbon is ground into powder, the powder is sieved with a sieve of 10-100 meshes, and anredera cordifolia derived carbon powder with uniform particles, namely, the sodium-ion battery electrode carbon material, is obtained. The preparation method has the characteristics of being simple to operate, easy to implement, high in repeatability, low in cost and causing no pollution to the environment. The anredera cordifolia derived carbon material prepared with the method is used as an anode material of room-temperature sodium ion batteries, the specific surface area of the material can be increased effectively, the battery capacity can be improved, and the battery cycle performance can be enhanced.

Description

technical field [0001] The invention belongs to the field of battery electrode materials, and relates to a sodium ion battery electrode carbon material, in particular to a method for preparing the sodium ion battery electrode carbon material by using yam. Background technique [0002] Although the lithium-ion battery technology is relatively mature, as its scope becomes wider and wider, especially in the large-scale application in the field of electric vehicles, we have to start to consider the sustainable development of lithium-ion batteries. According to the current development speed of electric vehicles, global lithium resources will not be able to effectively meet the huge demand for power lithium-ion batteries, which will further increase the price of lithium-related materials that were originally scarce, and will continue to increase battery costs, hindering the development of electric vehicles. The development of the new energy industry represented by Therefore, it i...
