| Abstract | Inspired by biomineralization, we develop a facile synthesis route to obtain 3D porous foam-like Na₃V₂(PO₄)₃@C composites consisting of ultra-small Na₃V₂(PO₄)₃ particles in situ wrapped with carbon architecture derived from yeast as storing sodium cathode. 3D carbon architecture with high electrical conductivity is endowed with important effect on bio-restricting the aggregation of Na₃V₂(PO₄)₃ nanoparticles, improving Na+ diffusion coefficient. As a result, the Na₃V₂(PO₄)₃@C cathode shows good rate performance with 109 mAh g−1 and 44 mAh g−1 at 0.5 C and 20 C, respectively. Besides, the storage mechanism and structure evolution of Na₃V₂(PO₄)₃@C have been certified by ex situ XRD and electrochemical impedance spectroscopy. The unique biomineralization process enables to improve the electrochemical performances of Na₃V₂(PO₄)3 by a facile self-organized process in a friendly environment. Therefore, biomineralization is a promising way to prepare high-performance cathode material with mesoporous structure for batteries. |
