“…1, all of the peaks for both samples in the X-ray diffraction patterns can be assigned to those of orthorhombic LiFePO 4 (space group: Pnma) as reported in the literature. 16) For the sample Cu-doped LiFePO 4 with carbon coating no evidence of diffraction peaks for crystalline carbon (graphite) appeared in the diffraction pattern, which indicating that the carbon generated from the carbon source (PEG/fructose) mixture was amorphous and that its presence did not influence the structure of Cu-doped LiFePO 4 . Additionally, in some previous work, the introduction of carbon or a carbon precursor into a lithium iron phosphate has led to produce iron or iron phosphides during the thermal treatment by carbothermal reduction, 15) but no copper neither as iron relative peak was detected in the XRD pattern in the present work.…”

“…14), 15) Croce et al 13) report the preparation and electrochemical performance of kinetically improved Cu-doped LiFePO 4 composite cathode materials. The added Cu metal powders do not affect the structure of LiFePO 4 but clearly improve its kinetics in terms of capacity delivery and cycling life due to a reduction of the particle size and an increase of the bulk intra-and inter-particle electronic conductivity of LiFePO 4 .…”

The Cu-doped LiFePO 4 with/without carbon coating was synthesized by solgel method. The material was characterized by X-ray diffraction, Raman spectroscopy, Scanning Electron Microscopy, Energy Dispersive Spectroscopy and its electrochemical properties were investigated by chargedischarge tests. For the carbon coated sample presents a high uniformity and a particle size around 50100 nm. Electrochemical tests show that the specified capacity was 102 mAh/g measured 0.25 C (1.5 mA) regime discharge rate, voltage range (2.53.7 V). Optimization of this composite would be required, but the Cu doping and carbon coating to LiFePO 4 showed a promising material for use as cathode material in lithium ion battery.

“…This implied that PLTB@PVDF-HFP based electrolyte was quite stable and compatible with LiFePO 4 electrode without noticeable corrosion after a long cycling time. The main reason for the slight decrease of discharge capacity after the repeated cycles was from the occurrence of the irreversible phase and structure within active material LiFePO4, not related to the PLTB@PVDF-HFP electrolyte [37,38].…”

A single-ion gel polymer electrolyte of PLTB@PVDF-HFP (polymeric lithium tartaric acid borate@poly(vinylidene fluoride-co-hexafluoropropene)) was prepared and its ionic conductivity was optimized via solvent composition tailoring. It was manifested that the ethylene carbonate/dimethyl carbonate (EC/DMC) swollen PLTB@PVDF-HFP exhibited a superior lithium ionic conductivity at room temperature to that of the traditional liquid electrolyte system (1 M LiPF 6 /EC/DMC). The Li 4 Ti 5 O 12 /LiFePO 4 cells using the EC/DMC swollen PLTB@PVDF-HFP as polymer electrolyte showed stable charge/discharge voltage profiles with small voltage hysteresis, preferable rate capability and excellent cycle performance at room temperature. These superior performances of EC/DMC swollen PLTB@ PVDF-HFP could endow this class of gel polymer electrolyte a very promising alternative to state of the art liquid electrolyte system.
