Abstract

The present invention pertains to the field of battery technology and provides a 3DP-nano-micro composite electrode material for high-performance lithium-ion storage, along with its preparation method. In this disclosure, a the V2O5—Ti2C3—Au nanocomposite cathode material featuring a hierarchical heterostructure for high-performance lithium ion energy storage is disclosed, comprising a 3D-printed V2O5—Ti2C3—Au cathode, in which an in-situ TiO2 interface forms via synergistic interactions between V2O5, Ti2C3Tx, and Au nanoparticles. The TiO2 interface introduces abundant oxygen vacancies that act as Li+ adsorption sites. Au nanoparticles contribute to interfacial redox dynamics, catalysis, and conductivity, forming Au—Ti intermetallics that act as conductive bridges, reduce interfacial resistance, and reinforce mechanical stability. The 3D-printed nanocomposite cathode is manufactured by DIW printing technology, which can accurately control the structure and spatial distribution of the active material, thereby shortening the ion/electron pathway and improving the electrochemical kinetics.
