NVP Carbon-Coated Sodium Vanadium Phosphate [Na₃V₂(PO₄)₃] Powder

Overview

Sodium vanadium phosphate (Na₃V₂(PO₄)₃, NVP) is a NASICON-structured cathode material widely studied for sodium-ion battery applications. Its robust three-dimensional framework enables fast sodium-ion diffusion and excellent structural stability during repeated charge–discharge cycles. The carbon-coated NVP powder supplied by TOB is engineered to enhance electronic conductivity while preserving the intrinsic ionic transport pathways of the phosphate lattice.

During electrochemical operation, sodium ions reversibly intercalate and de-intercalate within the Na₃V₂(PO₄)₃ framework via the V³⁺/V⁴⁺ redox couple, delivering stable voltage plateaus and high cycling durability. The carbon coating further improves rate capability by reducing charge-transfer resistance at the particle surface.
