The charge/discharge characteristics show a weak capacity-rate effect (for investigated C-rates up to 1 C) and a strong dependence on temperature (for investigated temperatures between 5 and 35 °C). This is a typical behavior for lithium-ion cells. 3) Both cells have a high electrical energy efficiency above 90% of the discharge/charge cycle.
This article presents a comparative experimental study of the electrical, structural, and chemical properties of large-format, 180 Ah prismatic lithium iron phosphate (LFP)/graphite lithium-ion battery cells from two different manufacturers. These cells are particularly used in the field of stationary energy storage such as home-storage systems.
The main objective of this work is to investigate the structural properties and lattice dynamics of several lithium-iron phosphates (LFPs) using Fourier transform infrared (FTIR) spectroscopy in a wide range of frequencies, from 100 to 2000 cm −1.
The crystalline phase corresponds to the orthorhombic γ-Li 3 Fe 2 (PO 4) 3 structure (o-LFP). The structure is based on a three dimensional network of [Fe 2 (PO 4) 3] x of FeO 6 octahedra and PO 4 tetrahedra sharing oxygen vertices. The lithium ions are situated in interstitial voids in the framework .
With the current global economy developing at a rapid pace, research into lithium-ion batteries has become a focal point in many major areas. Lithium iron phosphate, also known as LiFePO 4 or LFP, is one of the most promising cathode materials for commercial lithium batteries.
Lithium-iron phosphate materials were synthesized by wet-chemical techniques. The phospho-olivine compound LiFePO 4 was prepared by solution route using iron nitrate Fe (NO 3) 3 ·9H 2 O and LiH 2 PO 4 in distilled water. The resulting precursor was heated in an alumina boat at 500 °C for 10 h under Ar/5% H 2 atmosphere to reduce Fe 3+ to Fe 2+.
