Operando Gravimetric and Energy Loss Analysis of Na 3 V 2 (PO 4 ) 2 F 3 composite films by EQCM-D
Résumé
The ever-growing need for energy storage requires new technologies to meet the increasing demands. In this context, Sodium-ion (Na-ion) batteries have emerged as a potential complementary technology to Lithium-ion batteries. Among other materials, Na 3 V 2 (PO 4 ) 2 F 3 (NVPF) is a promising cathode for Na-ion batteries due to its high operating voltage and good energy density. In order to further characterize the (dis)charge behavior of NVPF, the electrochemical quartz microbalance with dissipation monitoring (EQCM-D) was employed to track both the frequency changes and dissipative losses at electrode/electrolyte interface.
