“…2. The peak that corresponds to O-H stretching found at wavenumber 3379 cm -1 , and peak corresponds to C-H stretching peak was detected at 2893 cm -1 [32]. The presence of GNP in the composite films result in a lower number of O-H stretching.…”

Bacterial cellulose (BC) was synthesized from pineapple peel extract media with addition of fermentation agent bacteria Acetobacter xylinum. BC was disintegrated from the pellicle into bacterial nanocellulose (BNC) by using a high-pressure homogenizer (hph) machine, which has a three-dimensional woven nanofibrous network. The synthesis of composite films started when BNC, graphite nanoplatelets, and cetyltrimethylammonium bromide (CTAB) were homogenized using an ultrasonic homogenizer then baked on a glass mold at a temperature of 80 degrees Celcius for 14h. A scanning electron microscope (SEM) was used to analyze its morphology. X-Ray diffraction spectra were used to analyze the composite films structure. The functional groups of the composite films were analyzed using the FTIR spectrum. SEM micrograph shows that GNP was evenly distributed into BNC matrix after CTAB addition. GNPs are shown as flat and smooth flakes with sharp corners. Some peak corresponds O-H, C-H, C≡C, and CH3 stretching was identified by using FTIR spectroscopy at wavenumber 3379, 2893, 2135, and 1340 cm-1, respectively. XRD analysis shows that Crystalline Index (C.I) of BNC increases after 2.5 wt% addition of GNP. The presence of CTAB decreases C.I value of composite films. BNC/GNP composite films have the best mechanical properties with Young’s modulus about 77.01 ± 8.564.

“…On the other hand, it has been found that some inorganic materials with strong polarity (such as 31 , Al 2 O 3 32 , TiO 2 33 , etc. ) possess good chemical affinity toward polysulfides, which can be used to confine the shuttle effect of lithium polysulfides during the cycling process of lithium–sulfur batteries.…”

“…For example, Zhao et al fabricated a self-standing film electrode for Li-ion batteries through a facile filter paper templating route, [25] while Rahman et al presented polyaniline (PANI) anchored to carbonized filer paper for application in supercapacitors. [26] Recently, filer paper has also been explored as an interlayer [27][28][29] and slurry-type cathode [30] for LiÀ S batteries. However, the most common kind of paper for daily use is arguably office paper in A4 size, which is consumed at 300 million tons per year.…”

Waste Office Paper Derived Cellulose‐Based Carbon Host in Freestanding Cathodes for Lithium‐Sulfur Batteries

et al. 2022

Due to large sulfur (S) content and simple manufacturing techniques, free-standing cathodes for lithium-sulfur (LiÀ S) batteries are gaining a lot of attention recently. Waste office paper, which is consumed in large quantities annually, was used to make a free-standing paper-based carbon (FPC) substrate, which inherited fiber-like morphology. In addition, reduced graphene oxide (rGO) nanosheets modified FPC (rGO@FPC) host was also prepared by a vacuum filtration method. After S impregnation, the FPC/S and rGO@FPC/S freestanding cathodes were employed in LiÀ S batteries. The rGO@FPC/S free-standing cathode exhibited extremely competitive electrochemical performance, including a reversible discharge capacity of 315 mAh g À 1 at 0.5 C after 500 cycles. This is due to the uniform S distribution, which boosts the utilization ratio, and the significant blocking action for polysulfide ions, which prevents the redox shuttle effect.
