Gradient carbon fluoride electrode and preparation method thereof

The invention relates to the technical field of chemical power sources, in particular to a gradient carbon fluoride electrode and a preparation method thereof.The preparation method comprises the steps that carbon fluoride positive electrode materials, conductive agents, sodium carboxymethyl cellulose and styrene-butadiene latex in different proportions are added into deionized water to be prepared into multiple kinds of sizing agents, a current collector is sequentially coated with the sizing agents, and the carbon fluoride gradient electrode is prepared; and the ratio of the carbon fluoride active material from the inner layer to the outer layer of the current collector is changed in a gradient manner. Through the gradient design of the carbon fluoride electrode, the distribution proportion of the conductive network of the carbon fluoride electrode and the carbon fluoride material can be obviously optimized, and the rate discharge performance of the lithium carbon fluoride battery is improved. 本发明涉及化学电源技术领域
