Pseudocapacitive Contributions to Electrochemical Energy Storage in TiO2 (Anatase) Nanoparticles
TL;DR: In this paper, the capacitive effects of nanostructured materials for electrochemical energy storage have been investigated over a dimensional regime where both capacitive and lithium intercalation processes contribute to the total stored charge.
Journal ArticleDOI
Porous Li4Ti5O12 Coated with N‐Doped Carbon from Ionic Liquids for Li‐Ion Batteries
TL;DR: In this paper, a uniform nitrogen-doped carbon coating layer is formed on Li4Ti5O12 particles by mixing porous Li4T2O12 powder with an ionic liquid and then treating the mixture at moderate temperature.

Large Impact of Particle Size on Insertion Reactions. A Case for Anatase LixTiO2
TL;DR: The particle size dependence of insertion reactions has been investigated for lithiated anatase TiO2, revealing progressively increasing Li capacity and Li-ion solubility for decreasing particle sizes, strongly deviating from the expected Li-rich andLi-poor phase separation as occurs in the bulk material.

Sustained Lithium-Storage Performance of Hierarchical, Nanoporous Anatase TiO2 at High Rates: Emphasis on Interfacial Storage Phenomena
TL;DR: In this paper, a hierarchical, nanoporous TiO2 structure is successfully prepared by a simple in situ hydrolysis method, and it achieves a sustained high lithium storage performance especially at high charge/discharge rates due to its substantially high surface area.

Zero‐Strain Insertion Material of Li [ Li1 / 3Ti5 / 3 ] O 4 for Rechargeable Lithium Cells
TL;DR: In this paper, a defect spinel-framework structure was examined in nonaqueous lithium cells and it was shown that the lattice dimension did not change during the reaction since the reaction consists of lithium ion and electron insertion into/extraction from the solid matrix without a noticeable change in lattice dimensions.
