Amplifier spurious input current components in electrode-electrolyte interface impedance measurements
BACKGROUND In Impedance Microbiology, the time during which the measuring equipment is connected to the bipolar cells is rather long, usually between 6 to 24 hrs for microorganisms with duplication times in the order of less than one hour and concentrations ranging from 10(1) to 10(7) [CFU/ml]. Under these conditions, the electrode-electrolyte interface impedance may show a slow drift of about ...
متن کاملConsiderations on electrical impedance measurements of electrolyte solutions in a four- electrode cell
A tetrapolar probe to measure the electrical properties of electrolyte solutions was implemented with gold electrodes according to the van der Pauw method. Electrical impedance spectroscopy (EIS) measurements of different concentrations of phosphate buffer saline (PBS) solution and an oral mucosal tissue sample dispersed in PBS were performed in the galvanostatic mode using a four-electrode cel...
متن کاملIntegrated description of electrode/electrolyte interfaces based on equivalent circuits and its verification using impedance measurements.
An integrated theory describing both faradaic and nonfaradaic currents obtained upon potential step at an electrified electrode/electrolyte interface has been developed based on equivalent circuits that had been used to explain electrochemical reactions and experimentally verified. The faradaic current is shown to consist of the mass transport-dependent and -independent parts, which is in gener...
متن کاملElectrode-electrolyte interface in Li-ion batteries: current understanding and new insights.
Understanding reactions at the electrode/electrolyte interface (EEI) is essential to developing strategies to enhance cycle life and safety of lithium batteries. Despite research in the past four decades, there is still limited understanding by what means different components are formed at the EEI and how they influence EEI layer properties. We review findings used to establish the well-known m...
متن کاملElectrode/Electrolyte Interface Studies in Lithium Batteries Using NMR
Easy access to portable energy sources has become necessary for the last decades and rechargeable batteries are now omnipresent in everyday tools and devices thanks to their storage capacity and relatively low weight. More recently, the possible use of lithium-ion batteries in full electric and hybrid electric vehicles has attracted considerable attention. However, great challenges still remain...
