【 摘 要 】

tsThe unique wire-in-wire structure endows TiO2/C nanofibers film with superior mechanical flexibility.The wire-in-wire TiO2/C nanofibers (TiO2 ww/CN) film shows outstanding electrochemical performances as free-standing anodes for Li/K-ion batteries and full cells.The TiO2 ww/CN film shows an extremely high pseudocapacitance contribution ratio in K-ion batteries.
