The invention provides a carbon electrode, a preparation method and the application thereof. The preparation method comprises the following steps: (1) mixing a carbon material, a binder emulsion and water to obtain slurry; (2) drying and fiberizing the slurry obtained in the step (1) to obtain a precursor material; and (3) mixing the precursor material obtained in the step (2) with a forming auxiliary agent, then performing kneading treatment, and performing rolling and baking to obtain the carbon electrode, the carbon electrode prepared by the method is relatively high in thickness uniformity, strength and toughness, and low in powder falling rate. 本发明提供了一种碳电极及其制备方法和应用，所述制备方法包括以下步骤：(1)将碳材料、粘结剂乳液和水混合得到浆料；(2)将步骤(1)得到的浆料进行干燥和纤维化得到前驱体材料；(3)将步骤(2)得到的前驱体材料和成型助剂混合后进行捏合处理，经辊压、烘烤得到所述碳电极，本发明所述方法制得的碳电极的厚度均匀性、强度和韧性都比较高，且掉粉率低。
