Three-dimensional branched TiO2 architectures (3D BTA) with controllable morphologies were synthesized via a facile template-free one-pot solvothermal route. The volume ratio of deionized water (DI water) and diethylene glycol in process is key to the formation 3D BTA assembled by nanowire-coated dendrites, which combines advantages hierarchical structure 1D nanoscale building blocks. Benefiting from such unique structural features, full bloom achieved significantly increased specific surface areas shortened Li+ ion/electrons diffusion pathway. lithium-ion batteries based on exhibited remarkably enhanced reversible capacity rate performance, attributing high contact area electrolyte short solid state pathway for promoting lithium insertion extraction.
