“…Nanomaterials which are based on graphene have been developed as 3D skeleton to produce an anode for lithium-ion batteries. The same materials show properties like high porosity structure and good electrical conductivity, thereby imparting excellent performance to the lithium-ion batteries (Writer, 2019). Moreover, metal oxide materials indicate an improvement in the distribution and continuation of electricity when reinforced with graphene, thus improving battery performance (Iqbal et al, 2020).…”

Technologies for wastewater remediation have been growing ever since the environmental and health concern is realized. Development of nanomaterials has enabled mankind to have different methods to treat the various kinds of inorganic and organic pollutants present in wastewater from many resources.Among the many materials, semiconductor materials have found many environmental applications due to their outstanding photocatalytic activities. TiO 2 and ZnO are more effectively used as photocatalyst or adsorbents in the withdrawal of inorganic as well as organic wastes from the wastewater. On the other hand, graphene is tremendously being investigated for applications in environmental remediation in view of the superior physical, optical, thermal, and electronic properties of graphene nanocomposites. In this work, graphene-TiO 2 and graphene-ZnO nanocomposites have been reviewed for photocatalytic wastewater treatment. The various preparation techniques of these nanocomposites have been discussed. Also, different design strategies for graphene-based photocatalyst have been revealed. These nanocomposites exhibit promising applications in most of the water purification processes which are reviewed in this work. Along with this, the development of these nanocomposites using biomass-derived graphene has also been introduced. Practitioner Points• Graphene-TiO 2 and graphene-ZnO nanocomposites are effective for wastewater treatment through photocatalysis.• These nanocomposite photocatalysts have been used in the form of membrane as well as antibacterial agents.• Synthetic strategies and design considerations of graphene-based photocatalyst play a major role.• Biomass-derived graphene-TiO 2 and graphene-ZnO nanocomposites have also found application in wastewater treatment.

“…While carbon-based anodes, such as graphite, have been widely used in commercial lithium-ion batteries (LIBs) due to their stable cycling performance, they suffer from relatively low theoretical gravimetric (370 mAh/g) and volumetric (840 mAh/cm 3 ) capacities that hinder wider penetration of markets that require higher energy densities. , Silicon (Si) emerges as one of the most promising anode materials by providing impressive gravimetric (3579 mAh/g, based on Li 15 Si 4 ) and volumetric (9786 mAh/cm 3 , based on the initial volume of Si) capacities as well as high abundance, low cost, negligible toxicity, high safety, and low operating potential (0.2–0.4 V vs Li/Li + ). − However, despite all of these resilient features, the cycling performance of Si-based anodes suffers from intrinsic drawbacks. As compared to the intercalation process of graphite that forms LiC 6 , the alloying process of Si can accommodate up to four Li atoms per Si atom.…”

Neutralization of poly(acrylic acid) (PAA)-based binders using lithium hydroxide is a common strategy for fabricating silicon anode laminates, which improves rheological properties of slurries toward high-quality electrode laminates. However, the significantly increased basicity causes degradation of Si particles while the irreversible conversion of carboxylic acid groups to lithium carboxylates undermines the binding strength, collectively leading to adverse cycling performance of the fabricated Si anodes. Herein, a novel neutralization process for PAA binders is developed. A weak base, ammonia (NH 3 ), was discovered as a neutralizing agent that still promotes rheological response of binder solutions but results in a reduced pH increase. Interestingly, the resulting ammonium carboxylate groups may cleave during the drying process to restore the neutralized PAA (PAA-NH 3 ) binders to their pristine states. The best-performing composition of 50% neutralization (PAA-50%NH 3 ) provides comparable rheological response as a PAA-Li binder as well as much improved cycling performance. The half-cells using the PAA-50%NH 3 binder can deliver 60% capacity retention over 100 cycles at C/3 rate, affording a 23.8% increase compared to PAA-Li half-cells. This restorable neutralization process of PAA binders represents an innovative strategy of mitigating issues from slurry processing of Si particles to achieve concurrent improvements in high-quality lamination and cycling performance.

“…In addition, the theoretical specific capacity of LiFePO 4 active-material is 0.170 Ah/g [27]. For graphite active-material, it is 0.372 Ah/g [40]. Consequently, assuming that the electrode capacity can be determined, the amount of active-material in grams for LiFePO 4 and graphite electrodes of a LIB can be respectively estimated as follows: m PE = C PE /0.170 g and m NE = C NE /0.372 g. This shows that an electrode capacity can be a useful and reliable parameter for the quantification of the electrode state of health.…”

In this paper, we propose a non-invasive method to determine the electrode balancing of the lithium-ion batteries, which is the determination of (i) individual electrodes capacities and (ii) individual curves of equilibrium potentials of the electrodes as functions of the battery state of charge. The proposed method requires the average measurements of the battery voltage between discharge and charge for a low current. This averaged voltage is then associated with the reference average curves of the electrode equilibrium potentials issued from literature. To determine the electrode balancing, the method was first used on a pristine LiFePO 4 /graphite cell. The results are consitent with this cell data and the proposed method accuracy is compared to a reference method of the litterature. We then used the proposed method on an aged cell of the same type to evaluate the method robustness with respect to the change in the cell state of health. The tracking of each electrode capacity during the battery lifespan can be used as a non-invasive diagnosis tool to monitor the state of health evolution to each electrode. Furthermore, the access to the individual curves of electrodes equilibrium potentials as functions of the battery state of charge is the first step towards the implementation of a non-invasive tool for an optimal prediction of the battery operating limits during fast recharging.
