Zero-dimensional quantum dots (QDs) are desired to enhance electrochemical response in energy storage. Here, we successfully synthesize well-dispersed and ultrafine TiO2-QDs, which are in situ embedded into the three-dimensional porous graphene-like networks (denoted as TiO2-QDs-3D GNs) via a simple low-temperature mixed solvothermal method, aiming at a fast electrochemistry with high-efficient electron and ion transport for lithium ion battery (LIB) anodes. By combining the advantages of the porous 3D GNs and ultrafine TiO2-QDs, the as-prepared TiO2-QDs-3D GNs hybrid electrode exhibits a high reversible capacity of 219mAhg−1 after 100 cycles at 0.1Ag−1, accompanied with an ultrahigh-rate capability of 121mAhg−1 and a super-long lifespan of 3000 cycles with ∼82.0% capacity retention at 10Ag−1. Detailed electrochemical analysis reveals that the superior rate capability and cycle performance are the main results of the integrated intercalation-based and interfacial lithium storage as well as the 3D fast electron/ion transfer of materials, which is attributed to the ultra-small size and high surface-to-volume ratio of TiO2-QDs as well as the 3D conducting networks of the integrated hybrid electrode. This study demonstrates the distinct advantages of our material design strategy, making it promising for the fast and ultralong-life anodes in LIBs.
