Abstract

The invention discloses an anode material and an anode plate of a lithium-iron disulfide battery and a method for preparing the same, wherein the anode material comprises iron disulfide which is an iron disulfide nanometer crystal, and FeSO4, (NH2)2CS and S taken as reaction raw materials and PVP taken as a dispersing agent react under the acid or alkali condition to prepare the iron disulfide. The obtained iron disulfide is an N-shaped crystal, of which the purity is as high as 100 percent; compared with the iron disulfide used in the prior art, the iron disulfide of the invention can greatly reduce the open circuit voltage of the lithium-iron disulfide battery, make the voltage platform more stable, improve the conductive activity of the battery, improve the discharging performance of heavy current, improve the discharging depth of the battery and make the lithium-iron disulfide battery have higher actual values.
