Hollow Mesoporous Co(PO3)2@Carbon Polyhedra as High Performance Anode Materials for Lithium Ion Batteries
JOURNAL OF PHYSICAL CHEMISTRY C(2019)
摘要
The hollow mesoporous Co(PO3)(2)@carbon nanocomposite (H-Co(PO3)(2)@C-') was synthesized using ZIF-67 as the template by a facile one-step thermal decomposition reaction. As an anode for lithium ion batteries, its reversible capacity remains up to 601 mAh g(-1) at 1 C after 500 cycles. Such a high reversible capacity along with the excellent rate capability and long-term cycling stability benefits from the hollow mesoporous structure and uniform carbon framework encapsulated active nanocrystals. These results render the as-prepared H-Co(PO3)(2)@C to be a promising anode material for high performance lithium ion batteries.
