Recent efforts in design of TiO_2(B) anodes for high-rate lithium-ion batteries: A review

摘要

In spite of latest research achievements, the development of energy storage devices with high power density and safety remains an urgent task. Among others, lithium-ion batteries are most promising power sources due to its good energy density and low self-discharge. The performance of lithium batteries depends on physicochemical characteristics of materials, which used as electrodes. Recently, among new materials, a special attention is paid to TiO2(B) owing to its high potential of lithium insertion/extraction (similar to 1.5 V vs. Li/Li+) and pseudocapacitive energy storage mechanism. However, the commercial application of bronze titania has been hampered to date by its poor electronic conductivity and lattice stresses during lithiation/delithiation. This review highlights recent progress in TiO2(B) modifying with a most promising ways, including morphology tailoring, hybridization, and doping. The main important achievements in this area are summarized and discussed in detail.
