“…Li 2 FeP 2 O 7 was synthesized by precipitation from aqueous solutions of LiNO 3 , FeSO 4 and (NH 4 ) 2 HPO 4 mixed in this order. 16 A new method was developed for the synthesis of composite Li 2 FeP 2 O 7 /carbon powders that utilized soluble methylcellulose as both a dispersing agent and a carbon source. XRD confirmed the presence of Li 2 FeP 2 O 7 as the major phase and also the olivine-type LiFePO 4 as a minor phase in amounts of around 9 wt.…”

Functional nanomaterials have held a steady position at the frontier of materials science and engineering in the 21st century. "Molecular Designing of Nanoparticles with Controlled Morphological and Physicochemical Characteristics and Functional Materials Based on Them? was the title of the research project funded by the Ministry of Education, Science and Technological Development of the Republic of Serbia and performed between 2011 and 2019 in the interdisciplinary area of nanoscience and nanotechnologies. Research activities within this program were divided to five interrelated topics: (1) From molecules to nanoparticles; (2) Advanced ceramics with improved functional properties; (3) Electrode materials for lithium-ion batteries; (4) Nano-calcium phosphate in preventive and regenerative medicine; (5) Biodegradable micro- and nano-particles for the controlled delivery of medicaments. This report gives an insight into this bibliographically most impactful Serbian national project on nanotechnologies executed within the aforementioned nine-year cycle, 2011 - 2019, focusing here only on the results achieved in the past three years. The project provided an outstanding and internationally recognized contribution to synthesis, characterization and functional design of a number of materials systems, including pure and lanthanide-doped hydroxyapatite, zinc oxides, sodium cobaltates, lithium iron pyrophosphates, lithium iron silicates and a number of polymeric systems.

The polyanion cathodes for Li-ion batteries, namely LiFePO 4 , Li 2 FeP 2 O 7 and Li 2 FeSiO 4 , were synthesized by very short high-temperature treatment (approximately several minutes) and subsequent quenching. Methylcellulose-a polymer with thermally driven water solubility-was used as the medium in which the precursor solutions were dispersed prior to high temperature treatment. The methylcellulose pyrolytically decomposes to carbon, thus producing the polyanion material/carbon composites of LiFePO 4 /C, Li 2 FeP 2 O 7 /C and Li 2 FeSiO 4 /C. The obtained powders have reduced crystallinity and significant microstructural characteristics: low crystallite size and notable microstrain. They exhibit stable electrochemical performances in both aqueous and organic electrolyte. The broadening of existing peaks in cyclic voltammetry and/or the emergence of new broad peaks was attributed to the presence of the amorphous phase in the samples. In galvanostatic charge-discharge tests, the materials provided high capacities at low current densities, while the highest rate performance was demonstrated by olivinephosphate when compared to the other two materials.
