The present application relates to a conductive agent, a preparation method therefor and the use thereof, and a current collector, a manufacturing method therefor, and the use thereof. The conductive agent comprises an organic oligomer and a conductive powder, the conductive powder being grafted to the organic oligomer. The conductive agent has conductivity; and since the conductive powder is modified by using the organic oligomer so as to graft the conductive powder to the organic oligomer, the organic oligomer can form a hydrophobic thin film layer on the surface of the conductive powder, so that the conductive powder has relatively low water absorption and thus is not liable to be affected by moisture in air. Therefore, the conductive agent can be used for preparing conductive coatings having low water absorption.
