Nanostructured TiO₂‐Based Anode Materials for High‐Performance Rechargeable Lithium‐Ion Batteries

Abstract

Lithium-ion batteries (LIBs), as the most widely used power source for portable electronics and the electric vehicles industry, are expected to exhibit high standards in terms of safety, long lifespan, high energy density, and high power density. However, the commercial graphite anode still suffers from potential safety issues. To address this challenge, TiO 2 -based materials are being widely explored as anode materials and promising progress has been achieved in the past few decades. In this review, we present the stateof-the-art for materials design strategies for TiO 2 materials to achieve high-performance LIBs. First, a brief discussion of the basic requirements for LIBs is introduced as a prerequisite. Second, for the purpose of improving the electrode performance with TiO 2 materials, the corresponding material engineering approaches are illustrated, which include intrinsic methods and extrinsic approaches. Lastly, the challenges and future perspectives for nanostructured TiO 2 toward high-performance LIBs are outlined. This review is expected to give a comprehensive understanding and guidance on TiO 2 -based materials in the application of energy storage devices.

Rutile TiO2 Inverse Opal Anodes for Li‐Ion Batteries with Long Cycle Life, High‐Rate Capability, and High Structural Stability

“…[2] TiO2 has also attracted a lot of attention as an intercalation mode material, being a low voltage insertion host for Li + and also as a fast Li + insertion/removal host, as well as having low environmental impact and cost. [3] Various polymorphs of TiO2 have been investigated as an anode material including TiO2(B), anatase and rutile. [4,5] The rutile phase of TiO2 is the most common natural form, as it is the most thermodynamically stable phase under standard conditions.…”

Controllable Synthesis of TiO2@Fe2O3 Core-Shell Nanotube Arrays with Double-Wall Coating as Superb Lithium-Ion Battery Anodes

“…TiO 2 possesses safe and stable working plateau potential (about 1.5–1.75 V versus Li/Li + ) without intense decomposition of electrolyte. Furthermore, taking advantage of favorable crystallographic characteristics and surface activity with negligible volume change during charging/discharging processes, TiO 2 material shows good structural stability, stable voltage output and long lifespan121314. Nevertheless, it is regretted that TiO 2 only delivers a low theoretical capacity (only 335 mA h g −1 ), which is even inferior to graphite1516.…”
