It was hypothesized that a lack of acetogenic biomass (biocatalyst) at the cathode of a microbial electrosynthesis system, due to electron and nutrient limitations, has prevented further improvement in acetate productivity and efficiency. In order to increase the biomass at the cathode and thereby performance, a bioelectrochemical system with this acetogenic community was operated under galvano...

Polypyrrole is one of the important conductive polymers that are widely used in energy storage systems, biosensors and electronics. The electrochemical synthesis of polypyrrole has advantages of simple process, mass production and low cost. In this study, polypyrrole thin films were deposited on different electrode substrates by cyclovoltammetric (CV), galvanostatic and potentiostatic depositio...

The experimental charge and discharge profiles of a LiCoO2 electrode show that the overpotential of the electrode does not change much during alvanostatic charge, but changes significantly during galvanostatic discharge. Semi-empirical porous electrode models are presented to simulate he charge and discharge profiles of the LiCoO2 electrode. The symmetry factor is empirically assumed to decreas...

An automated device for voltammetric measurements at a prescribed set of constant temperatures was put together in our institute. It allows one to take steady-state current-potential curves in the potentiostatic or galvanostatic mode, to do cyclic voltammetry or coulometry at constant potential or to measure the potential-time dependence at a constant current. A special holder for the solid ele...

This paper reports a modeling methodology to predict the effects on the discharge behavior of the cathode composition of a lithium iron phosphate (LFP) battery cell comprising a LFP cathode, a lithium metal anode, and an organic electrolyte. A one-dimensional model based on a finite element method is presented to calculate the cell voltage change of a LFP battery cell during galvanostatic disch...

Copper hexacyanoferrate (CuHCF) nanoparticles with tunnel-like Prussian blue structure were deposited on graphite substrate via pulse galvanostatic electrochemical deposition at 25 mA cm-2 with both on-time and off-time periods of 0.1 s, which presented the ability to intercalation/de-intercalation of Al ions reversibly in aqueous solution. The crystal structure of the as-prepared CuHCF f...
