In order to improve electrochemical performances of lithium ion battery (LIB), electrochemical integration of the membrane with the electrode was accomplished by conformal electrodeposition of poly(phenylene oxide) (PPO) on three‐dimensional (3D) oriented TiO 2 nanotube arrays (TiO 2 NT). The as‐synthesized PPO/TiO 2 NT membrane/electrode was investigated in terms of AC impedance, XPS, SEM, EDX, galvanostatic charge/discharge, rate performance, and cycle stability. As expected, PPO was indeed combined with TiO 2 NT via conformal electrodeposition; furthermore, the integrated PPO/TiO 2 NT membrane/electrode delivered much better rate performance than the traditional membrane/electrode, mainly attributed to large area of membrane/electrode/electrolyte, short ionic diffusion paths and fast ionic transport. © 2016 Wiley Periodicals, Inc.
