英文摘要Rational design & modulation of ion/electron transfer paths are critical for achieving high-performance anode materials for lithium ion batteries. In this work, we first time realize smart assembly of oxygen vacancy modulated titanium niobium oxide (Ti2Nb10O29-x, TNOx) onto highly conductive bacterial cellulose carbon (BCC) forming BCC/TNOx electrode through a facile solvothermal-annealing method. BCC consists of interlinked (N, S & P) co-doped carbon fibres uniformly decorated with TNOx nanoparticles. Impressively, the introduction of oxygen vacancy can effectively enhance the internal ion/electron transfer in TNOx and enhancement effect is elaborated by synchrotron radiation technology (XANES and XAFS) and DFT calculation. Meanwhile, with the aid of conductive BCC skeleton, the external ion/electron transfer path on TNOx is also greatly improved leading to better reaction kinetics. The synergistic dual internal plus external modulation on transfer path show positive advantages including smaller band gap with better electrical conductivity, and larger lattice parameters with faster ion/electron transfer. Accordingly, the BCC/TNOx electrode is endowed with outstanding lithium ion storage performance with high-rate capability (281 mA h g(-1) at 5 C, and 160.5 mA h g(-1) at 40 C). Our finding provides valuable insights into design of other advanced electrodes via dual transfer path modulation strategy.
