Does ocv of a half coin cell changed if the cells are created from one electrode?
Best insight from top research papers
The open circuit voltage (OCV) of a half coin cell can be affected if the cells are created from one electrode. Undersizing the Li metal electrode in a graphite/Li coin cell can lead to incomplete lithiation/delithiation processes of the graphite electrode edge, resulting in significantly lower charge/discharge capacities even at low rates . Additionally, the electrode alignment in coin-type LiNi0.6Mn0.2Co0.2O2/graphite full cells can impact the electrochemical properties. Misaligned cells exhibit lower specific discharge capacity and initial coulombic efficiency due to irreversible Li plating on the coin cell bottom during the first charging process. However, misaligned cells can also show a smaller low-frequency semicircle in the AC impedance spectra and lower DC-IRs at lowly charged states, indicating a less lithiated state of the misaligned cathode . Therefore, the electrode alignment and size of the metal electrode can have an impact on the OCV and electrochemical performance of half coin cells.

Why the cell is considered a dielectric?5 answersCells are considered dielectric because of their unique electrical properties. At low frequencies, cells exhibit conductivity characteristics, where the electrical signal cannot pass through the cell membrane due to its capacitor properties. As the excitation frequency increases, the cell behaves more like a permittivity characteristic, allowing current to flow through the membrane with increased current density. The dielectric response of cells is crucial for monitoring and characterizing their status, with modelling approaches providing insights into the interaction of biological matter with electromagnetic fields. Experimental studies have shown that both the real and imaginary parts of the Clausius-Mossotti factor are essential for deriving accurate cell dielectric properties, indicating changes in membrane and cytoplasm conductivities and permittivities under varying medium conductivities.
What is the effect of the distance between electrodes ?4 answersThe distance between electrodes has various effects depending on the context. In the case of the non-invasive vagus nerve stimulator, the distance between the electrodes is an important design factor for the effective delivery of electrical stimulation. For the deposition of hydrogenated diamond-like carbon films, the electrode distance affects the properties of the films. In the electrocoagulation reactor, the interelectrode distance influences the treatment time, formation of aluminum hydroxides, potential drop, and electric power consumption. Lastly, in the investigation of the electrostatic quadrupole deflector, the diameter of the deflector affects the imaging characteristics and efficiency.
Does the OCV of a half coin cell depend on the electrolyte?5 answersThe open circuit voltage (OCV) of a half coin cell does depend on the electrolyte used. The choice of electrolyte composition plays a vital role in determining the OCV of the cell. In the study by Keefe et al., the impedance spectra of lithium-ion symmetric cells were measured at low temperatures to separate the charge transfer impedance contributions from other cell impedance features. The OCV was found to be influenced by the faradaic charge transfer interactions, which were strongly temperature dependent. Therefore, the electrolyte composition affects the charge transfer resistances and capacitances of the solid electrolyte interphase layers on the electrodes, ultimately impacting the OCV of the half coin cell.
How the change of electrode material can change OCP?5 answersThe change of electrode material can affect the Open Circuit Potential (OCP) of a system. For example, the modification of a supercapacitor electrode with (La(1-x)Srx)(1-y)MnO(3-delta) material can increase the specific capacitance of the electrode during high-rate/high-current discharge by about 50%. Similarly, the introduction of TiN, platinum black, and iridium oxide to the stimulating sites of a flexible electrode can decrease the impedance of the electrode and improve its performance. Additionally, the surface modification of a positive electrode material using a positive electrode material surface modification apparatus can increase the specific capacity of the battery without degrading its electrochemical performance. Therefore, by changing the electrode material and modifying its surface, the OCP of a system can be influenced, leading to improved performance and increased specific capacitance.
How can a single cell under ultrasound be simulated?5 answersUltrasound cell delivery to simulate a single cell can be achieved using various techniques and models. One approach is the use of a MEMS ultrasound cell delivery device, which enables single-cell handling and precision analysis. Another method involves the use of ultrahigh frequency ultrasonic transducers, which can manipulate single cells and measure the actual acoustic radiation force (ARF) applied to the target cells. The three-dimensional distribution of ultrasound-induced cell disruption can be predicted by solving the Helmholtz equation using a three-dimensional acoustic module. Additionally, the effective medium theory (EMT) can be used to model ultrasound backscatter from aggregating cells, allowing for the simulation of a single cell aggregate and the decomposition of the backscattering cross-section into coherent and incoherent components. These techniques and models provide valuable insights into the behavior and response of single cells under ultrasound.
What is single cell recording?2 answersSingle cell recording is a technique used to study the activity and properties of individual neurons in vivo. It involves using various configurations, such as sharp intracellular, juxtacellular, loose-patch, and whole-cell approaches, to record and label individual neurons. This allows researchers to relate the physiology and morphology of single cells. Single cell recording is essential for understanding the role of specific cell types within local and brain-wide microcircuits. It provides valuable information for functional, neurochemical, and morphological identification of different cell types in a given region. Additionally, single cell recording is used in cognitive neuroscience to investigate the mechanisms underlying human cognition. By recording the activity of neurons in the awake, behaving brain, researchers can gather fundamental neural data for cognitive studies.
