dc.description.abstract | Various studies are conducted with an aim to increase the capacity and reduce of the lithium diffu-sion resistance during the charge/discharge of titanium oxide (TiO2), which is used as anode material in lithium-ion batteries. However, it is difficult to overcome the limited storage capacity and high dif-fusion resistance because of the intrinsic crystalline features of TiO2. This study demonstrates that the lithium storage limit and high lithium diffusion resistance of crystalline titanium oxide (c-TiO2) can be overcome by using amorphous titanium oxide (a-TiO2). The results of X-ray diffraction, X-ray absorp-tion spectroscopy, and galvanostatic intermittent titration show that a-TiO2 can store more Li-ions and has a reduced lithium diffusion resistance than c-TiO2. In contrast, the lithium storage of the crystalline structure is limited and its lithium diffusion resistance is high. The better performance of a-TiO2 can be ascribed to anomalous amorphous lithium storage sites, which provide additional lithium storage and open lithium diffusion paths. (C) 2021 Elsevier Ltd.
