Anomalous Discharge Behavior of Graphite Nanosheet Electrodes in Lithium-Oxygen Batteries

Charge–discharge stability of graphite anodes for lithium-ion batteries

A graphite powder disk sandwiched between two nickel screens was used as a lithium-insertion working electrode. Electrochemical impedance spectroscopy (EIS), galvanostatic intermittent titration (GIT) using pulsed microcurrent, and in-situ intrinsic resistance measurements were used for the evaluation of kinetics and intrinsic (i.e. physical) resistance changes during charge–discharge cycling f...

Photoelectrochemical Behavior of the MnO2 Nanosheet Electrodes

We recently synthesized a new modification of nanosized oxides such as titania [1] and manganese oxide [2] by delaminating precursor layered crystals into their elementary layers. The obtained materials have been named nanosheets on the basis of their two-dimensional morphology, as depicted in Fig. 1. The crystallite has an extremely small thickness less than 1 nm and a lateral size ranging fro...
