Titanium dioxide (TiO₂) anodes attract extensive attention because of their high security, good stability and low cost. But poor electronic conductivity and rate capability of TiO₂ limit its practical application in Lithium ion batteries (LIBs). In this paper, we design a TiO₂ based integrated electrode with binder free and electrical conductive structure through a simple and effective route.The TiO₂-carbonized PAN electrode delivers a reversible capacity of 377 mAh g^-1 after 100 charge-discharge cycles, which is much higher than that of commercial TiO₂ electrode. The improved anodic performance can be attributed to the conductive carbonized PAN coating layer, which is beneficial to facilitate the electron transport during the lithiation and de-lithiation reactions of TiO₂. Besides, the designed binderless structure effectively promotes the tight interconnection between TiO₂ and current collector. This paper may provide a new perspective and approach for the modification of commercial TiO₂ anodes.

二氧化钛（TiO ₂）阳极由于其高安全性，良好的稳定性和低成本而备受关注。但是，TiO _2的电子电导率和倍率性能差，限制了其在锂离子电池（LIBs）中的实际应用。在本文中，我们通过简单有效的方法设计了具有无粘合剂和导电结构的TiO ₂基集成电极。经过100次充放电循环，TiO ₂碳化PAN电极可提供377 mAh g ^-1的可逆容量，比市售的TiO ₂高得多电极。改善的阳极性能可以归因于导电碳化PAN涂层，其有利于在TiO ₂的锂化和去锂化反应期间促进电子传输。此外，设计的无粘结剂结构有效地促进了TiO ₂与集电器之间的紧密互连。本文可以为工业T​​iO ₂阳极的改性提供一个新的视角和方法。
