Comparison of electrochemical performances of olivine NaFePO4 in sodium-ion batteries and olivine LiFePO4 in lithium-ion batteries.
Carbon-coated olivine NaFePO(4) (C-NaFePO(4)) spherical particles with a uniform diameter of ∼80 nm are obtained by chemical delithiation and subsequent electrochemical sodiation of carbon-coated olivine LiFePO(4) (C-LiFePO(4)), which is synthesized by a solvothermal method. The C-NaFePO(4) electrodes are identical (particle size, particle size distribution, surface coating, and active material...
متن کاملIn Situ Atomic-Scale Imaging of Phase Boundary Migration in FePO
Orthorhombic Li x FePO 4 (0 ≤ x ≤ 1) system has attracted much attention for its application as a high power cathode material in lithium ion batteries. [ 1 ] Although the performance of this material has been greatly improved by cation doping, surface coating and size reduction, [ 2–4 ] the fundamental phase transformation mechanisms accompanying lithiation/delithiation are still controversial....
متن کاملSuppression of phase separation in LiFePO₄ nanoparticles during battery discharge.
Using a novel electrochemical phase-field model, we question the common belief that Li(X)FePO(4) nanoparticles always separate into Li-rich and Li-poor phases during battery discharge. For small currents, spinodal decomposition or nucleation leads to moving phase boundaries. Above a critical current density (in the Tafel regime), the spinodal disappears, and particles fill homogeneously, which ...

متن کاملKinetics of non-equilibrium lithium incorporation in LiFePO4.
Lithium-ion batteries are a key technology for multiple clean energy applications. Their energy and power density is largely determined by the cathode materials, which store Li by incorporation into their crystal structure. Most commercialized cathode materials, such as LiCoO(2) (ref. 1), LiMn(2)O(4) (ref. 2), Li(Ni,Co,Al)O(2) or Li(Ni,Co,Mn)O(2) (ref. 3), form solid solutions over a large conc...
