英文摘要Directional construction of high-rate anode is of great importance for the development of next-generation large-power lithium ion batteries. in the present work, we report a powerful combined strategy for smart construction of omnibearing conductive networks composed of tic/c arrays core and n-doped carbon (nc) shell to sandwich ti2nb10o29 (tno) nanoparticles forming integrated nc-tno@tic/c core/shell arrays. except for good electronic conductivity and high rigidity from tic/c arrays skeleton, lower energy barrier of li ion is obtained via the n-doped carbon layer facilitating the ion/electron transport kinetics according to dft results. accordingly, the nc-tno@tic/c electrode shows preeminent high-rate capacities (318 ma h g(-1) at 1 c and 202 ma h g(-1) at 50 c) and a long cycle life with a capacity retention of 85% after 10,000 cycles at 10 c, better than other tno counterpart due to the positive synergistic effect on enhanced ion/electron transfer and reinforced structure from conductive nc outer layer and tic/c skeleton. the full cell assembled by nc-tno@tic/c anode and lifepo4 (lfp) cathode also shows excellent electrochemical properties with promising application prospect. this polybasic structure design could offer guidelines for fabrication of other hybrid high-rate electrodes for energy storage devices.
