Electrochemical activity in oxyborates toward lithium

Résumé

We report the lithium insertion into a copper iron oxyborate, i.e. Cu2FeBO5. Four electrons are involved in the course of the first discharge, which is ascribed to the Cu2+/Cu redox couple. The reaction is associated with a collapse of the structure but this material shows a reversible and stable capacity of 180 mAh/g at 2.35 V vs. Li+/Li.
