The effects of carbon black specific surface area and morphology were investigated by characterizing four different carbon black additives and then evaluating the effect of adding them to the negative electrode of valve-regulated lead–acid batteries for electric bikes. Low-temperature performance, larger current discharge performance, charge acceptance, cycle life and water loss of the batteries with carbon black were studied. The results show that the addition of high-performance carbon black to the negative plate of lead–acid batteries has an important effect on the cycle performance at 100% depth-of-discharge conditions and the cycle life is 86.9% longer than that of the control batteries. The excellent performance of the batteries can be attributed to the high surface area carbon black effectively inhibiting the sulfation of the negative plate surface and improving the charge acceptance of the batteries.

Calcination Method

High surface area calcium aluminate is synthetized within a short time by using a carbon template solid state calcination method which involved addition of carbon black into the CaCO3 and Al2O3 powders, calcination, and carbon removal by steam. Vary carbon black dosage changed the textural properties of the calcium aluminate, such as the surface area. By varying carbon black dosage from 0 to 10.0 wt%, the calcium aluminate with a surface area ranging from 21.5 to 41.2 m2and#183;g–1 are successfully synthesized within 14.0 h. Furthermore, the nanometer sized CaCO3 and Al2O3 powders comprising carbon black could markedly reduce the calcination temperature without reducing the surface area. This research might lead to the cost-effective synthesis of calcium aluminate (Ca12Al14O33) in a short synthesis period.

Future Challenges

Carbon black (CB) is a nanostructured material widely used in several industrial processes. This nanomaterial features a set of remarkable properties including high surface area, high thermal and electrical conductivity, and very low cost. Several studies have explored the applicability of CB in electrochemical fields. Recent data showed that modified electrodes based on CB present fast charge transfer and high electroactive surface area, comparable to carbon nanotubes and graphene. These characteristics make CB a promising candidate for the design of electrochemical sensors and biosensors. In this review, we highlight recent advances in the use of CB as a template for biosensing. As will be seen, we discuss the main biosensing strategies adopted for enzymatic catalysis for several target analytes, such as glucose, hydrogen peroxide, and environmental contaminants. Recent applications of CB on DNA-based biosensors are also described. Finally, future challenges and trends of CB use in bioanalytical chemistry are discussed.

Abstract This paper has attempted to review current knowledge on mixing fundamentals from a carbon black standpoint. The mixing parameters discussed include volume fill factor, specific energy of mixing, temperature buildup, and flow characteristics. Together, these parameters define the economics of mixing in terms of mixing capacity, energy expenditure, limitations imposed by dump temperature on second-stage operations, and extruder flow requirements. The four parameters in turn were related to basic carbon black properties by way of mixing profiles. Ten currently available tread blacks which exhibit a wide range of tread wear resistance have been characterized in terms of the processability criteria. A processability rating system based on the most simple equipment requirement (a Banbury followed immediately by a second-stage mill or an extruder) was applied to the ten blacks. Comparison of the processability ratings with the tread wear ratings clearly demonstrates that a valid assessment of carbon black utility must include processing cost in addition to performance capability. As in many rubber properties, there is clearly an inverse relationship between performance quality and processability. High-structure, high-surface-area blacks that are desirable from a performance standpoint require the highest processing cost. The question of uniformity was also discussed, and it was concluded that the present specifications controlling carbon black surface area and structure are adequate in minimizing processing variations. The challenge to processing technology from a carbon black standpoint then involves the reduction in the cost of processing high-structure, high-surface-area blacks. At this stage, a quantitative measure of the processing characteristics of the currently available tread blacks at least allows a rational product selection in terms of optimum performance and processing cost. In the meantime, it is evident that significant advances in carbon black technology are still needed if performance optimization is to be reconciled with the economics of processing.
