Enhanced electrochemical properties of LiFePO4/C synthesized with two kinds of carbon sources, PEG-4000 (organic) and Super p (inorganic)

“…A 3D conductive network can be built by using the carbon nanotubes or graphene layers but conductive paths for the individual particles are required. The combination of individual particle coating with the 3D conductive network is highly promising …”

“…Geordneter Graphit ist leitfähiger und ermöglicht eine schnellere Li + ‐Diffusion als ungeordneter Graphit, sodass der Grad an Graphitbildung einen wesentlichen Einfluss auf die elektrochemische Leistung des Materials haben kann . Als sehr aussichtsreich hat sich eine Kombination aus Einzelpartikelbeschichtung und leitfähigem 3D‐Netzwerk erwiesen …”

“…PEG has been commonly utilized because it is nontoxic, flexible, and hydrophilic and has a high affinity for silanol groups . Nevertheless, pure PEG has low moduli, that is, 100–200 MPa (tensile) and 10–100 MPa (shear) for PEG .…”

The effect of silica polymorphs on the thermomechanical properties of 0, 5, 10, and 20 wt % silica particles-reinforced-based poly(ethylene glycol) (PEG) composites have been studied as a function of temperature using dynamic mechanical analysis (DMA). The silica polymorphs exhibited quartz (Q), cristobalite (C), and amorphous (A) phases, which were obtained by processing natural silica sand. The DMA thermomechanical properties were determined in tensile (E) and shear (G) modes. The maximum storage moduli (E 0 and G 0 ) were achieved by samples with 20 wt % silica for all type of fillers. These values increased approximately 12 times for PEG/Q, 10 times for PEG/A, and 11 times for PEG/C composites compared to the pure PEG. Furthermore, the Poisson's ratio values of the composites were filler phase dependent, that is, 0.39-0.47 for PEG/Q, 0.15-0.18 for PEG/A, and somewhat anomalous for PEG/C composites.
