摘要：
Structurally identical KVPO4F and KVOPO4 are evaluated as positive electrode materials for non-aqueous potassium-ion batteries. KVPO4F and KVOPO4 show highly reversible potassium extraction/ insertion with discharge capacities of ca. 92mA h g(-1) and ca. 84 mA h g(-1), respectively, and their average discharge voltage reaches above 4.0 V with 1 M KPF6 EC/PC electrolyte at 2.0-5.0 V. Despite the extraction of large potassium-ions, their lattice volume shrinkages after charging to 5.0 V are 5.8% for KVPO4F and 3.3% for KVOPO4, leading to stable cycle performance. This is the first report to confirm the charge/discharge behaviours of vanadium phosphate electrodes in 4 V-class K cells.
