Abstract

Carbon bonded and encapsulated selenium composites were synthesized in a sealed vacuum glass tube at a high temperature. Because selenium is bonded and encapsulated by carbon, the shuttle reaction of selenium was effectively suppressed. The C/Se composites exhibit a superior cycling stability and rate capability in commercial carbonate based electrolytes.
