“…However, amorphous carbon in the composite product was experimentally detected by Raman spectroscopy (Fig. S1, Supporting information) [41]. An additional small and broad peak at ∼30 • may be due to the presence of amorphous phase as the synthesis method is conducted at relatively low temperature.…”

“…Any broad peaks or lines corresponding to amorphous or crystalline carbon were of insuffi cient intensity to be detected against the background in the XRD pattern of Li 4 Ti 5 O 12 -TiO 2 -C nanocomposite. However, amorphous carbon [ 48 ] in the composite product was detected by Raman spectroscopy ( Figure S1 in Supporting Information) and by TEM examination (described later). The approximate crystallite sizes of the Li 4 at 60 ° C, which could be attributed to the loss of moisture and volatile organic compounds ( ∼ 3 wt.%) contained in the sample.…”

This work introduces an effective, inexpensive, and large‐scale production approach to the synthesis of a carbon coated, high grain boundary density, dual phase Li4Ti5O12‐TiO2 nanocomposite anode material for use in rechargeable lithium‐ion batteries. The microstructure and morphology of the Li4Ti5O12‐TiO2‐C product were characterized systematically. The Li4Ti5O12‐TiO2‐C nanocomposite electrode yielded good electrochemical performance in terms of high capacity (166 mAh g−1 at a current density of 0.5 C), good cycling stability, and excellent rate capability (110 mAh g−1 at a current density of 10 C up to 100 cycles). The likely contributing factors to the excellent electrochemical performance of the Li4Ti5O12‐TiO2‐C nanocomposite could be related to the improved morphology, including the presence of high grain boundary density among the nanoparticles, carbon layering on each nanocrystal, and grain boundary interface areas embedded in a carbon matrix, where electronic transport properties were tuned by interfacial design and by varying the spacing of interfaces down to the nanoscale regime, in which the grain boundary interface embedded carbon matrix can store electrolyte and allows more channels for the Li+ ion insertion/extraction reaction. This research suggests that carbon‐coated dual phase Li4Ti5O12‐TiO2 nanocomposites could be suitable for use as a high rate performance anode material for lithium‐ion batteries.

“…Considering the well-known silver antibacterial activity, amorphous carbon films with silver nanoparticles inclusions were produced and the biocompatibility and antibacterial properties of such films was evaluated. Details concerning the deposition conditions and properties of the films can be found somewhere else (Garcia-Zarco et al, 2009). …”
