Full textUnderstanding the formation and structure of the electrical double layer (EDL) in state-of-the-art capacitive electrode materials is crucial for preparing the next-generation of fast charging and high-power energy storage systems. However, experimental investigations of the charging kinetics of porous carbon electrodes, the materials of choice for electrochemical capacitors, pose significant challenges due to rapid ion dynamics; this is the challenge we want to address in this work. This thesis starts with a focus on carbide-derived porous carbon (CDC), employing chronoamperometry in electrolytes of varying concentrations. Using a cavity micro-electrode setup, we were able to observe electrolyte depletion and we systematically analyzed its impacts on charging the kinetics. Results indicated that for low electrolyte concentration (10-3 M), high overpotential (> 200 mV), and small carbon pore size (0.6 nm) exacerbated electrolyte depletion, slowing down ion transportation. Then, we further investigated the charge storage mechanism in reduced graphene oxide (rGO) electrodes in near-neutral aqueous electrolytes. Operando EQCM results depicted a two-step cation adsorption mechanism with i) initial hydrated cation adsorption at low overpotential followed by cation dehydration for higher overvoltage(>200 mV). Notably, a significant increase in capacitance was observed due to cation dehydration, with the degree of enhancement correlating with non-electrostatic cation-rGO interactions due the negative charge of the rGO surface (zeta potential). These findings underscore the critical role of ion-electrode interactions and cation desolvation in modulating the charge storage mechanisms and capacitance. In a last part, we used conductive layered metal-organic frameworks (MOFs) as electrode materials. These MOFs revealed a cation-dominated charge storage mechanism in non-aqueous electrolytes via EQCM measurements. The use of small size cations (tetraethylammonium) resulted in improved capacity, while larger cations (butyl, hexyl ammonium) saturated MOF electrode pores, leading to asymmetric and sluggish charging dynamics, forcing solvent molecules to participate in the charge storage mechanism under nanopore confinement. The discoveries of this thesis significantly advance our understanding of ion electrosorption, ion transportation, and the role of solvent dynamics in confined pores, thus guiding the design of materials with improved performance for capacitive energy storage devices

Spot defects are a leading source of failure in the fabrication of integrated circuits (ICs). Thus, the IC industry inspects for defects at multiple stages of IC fabrication, especially the fabrication of IC photomasks. However, existing non-invasive imaging methods cannot image a modern photomask in a reasonable time-frame. Electroquasistatic (EQS) sensors are arrays of electrode pairs that capacitively couple to targets they sweep over. Utilizing high measurement frequencies and a number of parallel scanning electrode pairs, EQS sensors have been suggested as a potential high speed alternative for defect detection in IC fabrication. This thesis continues the investigation into EQS sensors for high speed imaging by exploring EQS sensors driven with high excitation frequencies. We develop electrode arrays that can be driven with high excitation frequencies and construct high frequency EQS sensors by attaching them to high frequency drive electronics. We also fabricate a test fixture for positioning these sensors relative to and sweeping them across targets on a conductive base. As the sensors sweep across targets, their impedance is measured from 1 - 500 MHz using an impedance analyzer and is later converted into the capacitance between the sensor's electrode array and the target. Capacitance changes are produced by a variable air gap and by a dielectric step, confirming these sensors can detect changes in a target's geometric and material properties with high excitation frequencies. Finally, we present concepts for a high speed measurement system which utilizes these sensors.

Full textGiven the global warming issues, finding clean and sustainable energy resources to replace conventional fossil fuels is of paramount importance. Osmotic energy remains an untapped energy resource with significant potential. In this work, we achieve efficient conversion of osmotic energy into electricity through a well-controlled mixing process using a capacitive reverse electrodialysis (CRED) system. It is demonstrated that a substantial power density gap exists between the CRED system and the theoretical maximum value, primarily due to the low ionic-electronic flux conversion efficiency in capacitive electrodes. To address this limitation, we propose the boosting strategy to optimize the working regime of the CRED system. Both experiments and modeling confirm an enhanced energy performance of the CRED system. To advance towards real-world applications, we assess the performance of the CRED system under solutions composed of complex ion mixing. In contrast to the significant power density drop observed in classic RED systems, the CRED system exhibits only a minor decrease when subjected to solutions with divalent ion mixing. This phenomenon is attributed to the periodic water chamber reversal, which mitigates the membrane poisoning effect. This result is further validated through long-term testing with real-world solutions. To generalize the CRED system into a broader spectrum, we propose a pH gradient cell with MnO2 electrodes of pseudo capacitance. It uses the osmotic energy established within an electrolyte based CO2 capturing process and aims to reduce the overall cost of carbon capturing process. The pH gradient cell presents unexpected power density increase under boosting strategy. This is due to the additional electrode voltage contribution due to fractional coverage change related to redox reactions. However, it stays in the framework of capacitive regime and remains well described by an adapted CRED modeling

Full textMembrane Capacitive Deionisation (MCDI) is a technology used to desalinate water where a potential is applied to an electrode made of carbonaceous materials resulting in ion adsorption. Processes and materials for the production of electrodes to be applied in Membrane Capacitive Deionisation processes were investigated. The optimal electrode composition and synthesis approached was determined through analysis of the salt removal capacity and the rate at which the electrodes absorb and desorb ions. To determine the conductivity of these electrodes, the four point probe method was used. Contact angle measurements were performed to determine the hydrophilic nature of the electrodes. N2 adsorption was done in order to determine the surface area of carbonaceous materials as well as electrodes fabricated in this study. Scanning electron microscopy was utilised to investigate the morphology. Electrodes were produced with a range of research variables; (i) three different methods; slurry infiltration by calendaring, infiltration ink dropwise and spray-coating, (ii) electrodes with two different active material/binder ratios and a constant conductive additive ratio were produced in order to find the optimum, (iii) two different commercially available activated carbon materials were used in this study (YP50F and YP80F), (iv) two different commercially available electrode substrates were utilised (JNT45 and SGDL), (v) different slurry mixing times were investigated showing the importance of mixing, and (vi) samples were treated at three different temperatures to establish the optimal drying conditions. Through optimization of the various parameters, the maximum adsorption capacity of the electrode was incrementally increased by 36 %, from 16 mg·g-1 at the start of the thesis to 25 mg·g-1 at the end of the study.

Full textTo effectively combat global warming, it is necessary to increase the production of clean, renewable energy. Solar, wind power, hydroelectric dams and tidal power plants are mature technologies. Increasing the production of this energy requires the use of energy sources that are little or not exploited like the blue energy which is the a less-known source with enormous potential that can be generated directly from the mixing of fresh and salt water. However, current processes for energy harvesting from salt gradients remain inefficient mainly because commercial selective membranes have poor performance as in the reverse electrodialysis or in the pressure retarded osmosis and still not economically viable. Hopes for nonselective membranes with charged nanofluidic channels which have been designed to reduce the internal resistance of the cell seem to be in vain. Here we present a novel solution that involves increasing the open circuit potential of the membrane by attaching tailored capacitive layers with negatively charged functional groups on the surface that adsorb ions, mainly the positive ones. Such a configuration allows us to double the potential of the open circuit of the cell without modifying too much the global ohmic resistance and thus to multiply by 4 the potentially recoverable power.After a thorough study carried out in order to characterize the process and an optimization of the energy consumption caused by the hydraulic pressure drop, we display a device of a few squared centimeters with only one membrane harvesting a net power density of 2 Watts per square meter of the membrane (estimated net potential power density 5.4 W.m−2 ) which makes the system economically viable
