Lithium-Ion Cathode/Coating Pairs for Transition Metal Containment

Hierarchically Nanostructured Transition Metal Oxides for Lithium‐Ion Batteries

Lithium-ion batteries (LIBs) have been widely used in the field of portable electric devices because of their high energy density and long cycling life. To further improve the performance of LIBs, it is of great importance to develop new electrode materials. Various transition metal oxides (TMOs) have been extensively investigated as electrode materials for LIBs. According to the reaction mecha...

Nanostructured Transition Metal Chalcogenides as Materials in Lithium Ion Batteries

Metal hydrides for lithium-ion batteries.

Classical electrodes for Li-ion technology operate via an insertion/de-insertion process. Recently, conversion electrodes have shown the capability of greater capacity, but have so far suffered from a marked hysteresis in voltage between charge and discharge, leading to poor energy efficiency and voltages. Here, we present the electrochemical reactivity of MgH(2) with Li that constitutes the fi...

Electroplating lithium transition metal oxides

Materials synthesis often provides opportunities for innovation. We demonstrate a general low-temperature (260°C) molten salt electrodeposition approach to directly electroplate the important lithium-ion (Li-ion) battery cathode materials LiCoO2, LiMn2O4, and Al-doped LiCoO2. The crystallinities and electrochemical capacities of the electroplated oxides are comparable to those of the powders sy...

Advancement in Layered Transition Metal Dichalcogenide Composites for Lithium and Sodium Ion Batteries

With an ever increasing energy demand and environmental issues, many state-of-the-art nanostructured electrode materials have been developed for energy storage devices and they include batteries, supercapacitors and fuel cells. Among these electrode materials, L-TMD (layered transition metal dichalcogenide) nanosheets (especially, S (sulfur) and Se (selenium) based dichalcogenides) have receive...
