(De)lithiation mechanism of Li/SeS(x) (x = 0-7) batteries determined by in situ synchrotron X-ray diffraction and X-ray absorption spectroscopy.
Electrical energy storage for transportation has gone beyond the limit of converntional lithium ion batteries currently. New material or new battery system development is an alternative approach toExpand

Li-Se battery: absence of lithium polyselenides in carbonate based electrolyte.
The lithiation mechanism of the Li-Se cell in a carbonate-based electrolyte is discussed. It is found that Se is directly reduced to Li2Se in discharge without intermediate phases detected by in situExpand

Enabling high energy density Li-ion batteries through Li2O activation
Abstract Lithium oxide (Li2O) is activated in the presence of a layered composite cathode material (HEM) significantly increasing the energy density of lithium-ion batteries. The degree of activationExpand

Selenium and Selenium Sulfide − A New Class of Positive Electrode Material for Room Temperature Lithium and Sodium Rechargeable Batteries
In this study, we introduce new materials based on Se-C and SexSy-Cas positive electrodes for Li and Na rechargeable batteries. The Li/Se provides at least 0.5 V higher output voltage than the Li/SExpand
Ca Cobaltites as Potential Cathode Materials for Rechargeable Ca-Ion Batteries: Theory and Experiment
Rechargeable Ca-based batteries can potentially achieve higher energy capacity than Li-ion batteries. The development of Ca-ion batteries, however, remains in its infancy, especially due to the cha...
