Synthesis and microstructural characterization of phosphate cathode materials prepared by a polymeric steric entrapment precursor route
… Then the variables were tuned to produce NaFePO4 and NaTi2(PO4)3 based on the concepts learned from the model system. NaFePO4 (maricite) was synthesized at low temperature (~ 300 ºC) using PVA as a polymer carrier and dissolving stoichiometric amounts of NaNO3, Fe(NO3)3•9H2O and (NH4)2HPO4 …

A generalized form for frequency-response modeling of battery energy storage systems
… lithium-ion (NMC811), and a 1.5 Ah sodium-ion (NaFePO4) cell. An extensive experimental protocol was executed, subjecting the cells to conditions including temperatures from −20°C to +60°C, states of charge from 0-100%, aging up to 280 cycles, and mechanical damage (indentation and bending). …

Electrochemically-induced phase transition in olivine type cathode materials
… y<0.5), 5vol% for LiFePO4 (LFP), to 17vol% for NaFePO4 (NFP), have been studied using operando Powder X-ray Diffraction (PXD), among other methods. While small transformation strain as in LMFP is accommodated and even avoided by formation of metastable solid solution, large transformation strain …
