Modelling the effect of anode particle radius and anode reaction rate constant on capacity fading of Li-ion batteries

This paper investigates the effect of anode particle radius and anode reaction rate constant on the capacity fading of lithium-ion batteries. It is observed through simulation results that capacity fade will be lower when the anode particle size is smaller. Simulation results also show that the reaction rate constant for the anode reaction has a good impact on the capacity loss of a lithium-ion battery. The potential drop across the SEI layer (solid electrolyte interphase) is studied as a function of the anode particle radius and anode reaction rate constant. Modelling results are compared with experimental data and found to compare well.

Core-Shell Nanoparticle with Tensile Strain Enables Highly Efficient Electrochemical Ethanol Oxidation

The ethanol oxidation reaction (EOR), the anode reaction of direct ethanol fuel cells, suffers from the sluggish oxidation kinetics and its low selectivity toward complete oxidation to CO2. The key...

Dry electrochemical polishing of copper alloy in a medium containing ion-exchange resin

At each collision between resin particles and material surface, a micro electrolytic cell is formed at the contact point and an anode reaction occurs. Metal ions from the reaction enter the resin and are carried away at the end of the collision.

Electrochemical Behavior of CsI in LiCl Molten Salt

The electrochemical behavior of CsI in LiCl molten salt was investigated to identify its impact on the electrolytic oxide reduction of oxide-phase spent nuclear fuels by combined electrolysis and cyclic voltammetry experiments of LiCl-CsI in comparison with LiCl, LiCl-CsCl, and LiCl-LiI. It was found that Cs+ ions were hardly involved in the cathode reaction, and reduction of Li+ ions occurred dominantly in the cathode. In contrast, incorporation of I− ions induced low-potential anode reaction compared with the I− ion-free cases. Such additional electrochemical reaction resulted in the generation of I2 and/or ICl gases, which would increase a process burden for treating 129I with exceptionally long lifetime. In this respect, separating CsI from spent nuclear fuel before the electrolytic oxide reduction is recommended for the purpose of efficient waste management.
