titleOfInvention | Preparation method of iron-nickel battery negative electrode material |
abstract | A preparation method of an iron-nickel battery negative electrode material belongs to the technical field of battery negative electrode material production, carbon dioxide and a suspension obtained by mixing a carbon nano tube, graphene, nano ferroferric oxide, calcium hydroxide and water are subjected to gas-solid reaction, when the pH value of the suspension is reduced to 7, a filter cake is obtained by filtering, then the filter cake is mixed with a hydroxyethyl cellulose aqueous solution to obtain composite nano material slurry, and the composite nano material slurry is coated on a copper net to be subjected to vacuum drying, rolling and slicing to obtain an iron-nickel battery negative electrode sheet. According to the invention, the submicron calcium carbonate is used for loading the composite material of graphene, carbon nano tubes and ferroferric oxide nano tubes through the gas-solid reaction of carbon dioxide and calcium hydroxide, so that the iron-nickel battery cathode material with high gram-volume, low resistance and good cycle stability is prepared. |
