Abstract
A new kind of oxygen-rich carbon microsphere with a nanoflake-interlaced architecture has been successfully prepared by a facile surfactant-assisted precipitation-polymerization method. This hierarchical infrastructure can efficiently buffer the volume change during the potassiation/depotassiation cycles.
