The present application relates to the technical field of electrode paste, and discloses a high-conductivity and low-energy-consumption electrode paste prepared by closed baking and a preparation process.The electrode paste of the present application is composed of composite carbonaceous base material, conductive graphite powder, modified pitch binder and boron-silicon composite modifier, and can be added with two-dimensional transition metal carbonitride and in-situ fiber-forming polymer; through multi-component and closed segmented baking, the present application realizes the synchronous improvement of the conductivity and mechanical strength of the electrode paste while optimizing the aggregate accumulation, strengthening the interface bonding, constructing the conductive network and three-dimensional toughening structure, and the obtained product has the characteristics of low resistivity, high pressure strength and low electrode consumption, and is suitable for self-baking electrodes of ore smelting furnaces, and reduces the energy consumption and cost while ensuring high performance.

The application discloses a split type elastic reinforced low internal resistance conductive structure for cylindrical lithium batteries, which comprises a conductive part 1, an elastic part 2, a blackening prevention contact surface 3, a supporting and positioning structure 4 and a mounting clamp 5. The conductive part 1 is made of high-conductive material and is used for bearing current conduction; the elastic part 2 is used for providing elastic pressure and preventing poor contact caused by deformation, and is independent of the conductive part 1 and does not participate in current conduction; the supporting and positioning structure 4 and the mounting clamp 5 are used for fixing the conductive part 1 and the elastic part 2 assembly in the battery cabin. The structure has the advantages of low contact resistance, high current carrying capacity, strong blackening resistance, long service life and adaptability to various types of cylindrical lithium batteries.
