Simulation and Design of Lithium Ion Battery Packs for the Altitude Conditions in Northern Chile

A. Mallco Carpio [1], M. Cortes Carmona [1],
[1] University of Antofagasta, Antofagasta Energy Center, Antofagasta, Chile

One of the most noticeable effects in loss of performance and capacity of thermal systems is produced by altitude. This causes that the density of a compressible fluid and the atmospheric pressure are considerably reduced, causing a decrease in electrical power and thermal systems. Given ... Read More

Uncertainty Assessment and Sensitivity Analysis of Heat Generation within a Lithium-Ion Battery

G. Liebig [1], G. Gupta [1], K. Derendorf [1], C. Agert [1],
[1] DLR Institute of Networked Energy Systems, Oldenburg, Germany

Dedicated work in modeling, simulation and design optimization of Lithium-ion Battery (LIBs) was done in the past decades, and still, the most widely used one for electrochemical processes is the Newman model. [1] The underlying parameters are treated deterministically, but the impact of ... Read More

Modeling and Simulation of Redox Titration of Metal Oxides at Porous Microelectrodes

L. Balboa [1], M. Hänsch [1] , J. Behnken [1], G. Wittstock [1],
[1] Institute of Chemistry, Carl von Ossietzky University of Oldenburg, Oldenburg, Germany

In the past two decades, highly porous nanostructured materials have been investigated and used for a large variety of applications, such as catalysis, energy conversion/storage, optics, sensing and more. Nanoporous gold (npAu) is one of such materials which have shown great potential as ... Read More

2-D Modeling of CO2 Electrolysis Using Gas Diffusion Electrode Operate at Neutral pH and Mild Conditions

A. Monteverde Videla[1], N. Vasile[1], G. Saracco[1]
[1] Istituto Italiano di Tecnologia, Centre for Sustainable Future Technologies, Turin, Italy

CO2 capture and further conversion into valuable products can be a promising solution against global warming. Normally, CO2 conversion can be achieved by chemical methods, by photocatalytic and electrocatalytic reduction [1]. Specifically for electrocatalytic reduction of CO2, challenges ... Read More

Implementation of an Active Fluid Cooling Design in a 48 V High-Power Battery Module

Z. Wu [1], A. Stawarski [2], H. Kemper [2],
[1] Energy Storage Systems, FH Aachen - University of Applied Sciences, Aachen, Germany; RWTH Aachen University, Aachen, Germany
[2] Energy Storage Systems, FH Aachen - University of Applied Sciences, Aachen, Germany

Individual batteries have their own operational temperature ranges, which shall be respected to avoid both damaging of the cells and shortening of the cycle life. In terms of the Li-Ion cells, many of them do not function well at higher temperatures. Therefore, a better understanding of ... Read More

Copper Electrochemical Polishing Optimisation

A. Pérez Rodríguez [1], L. Marques Antunes Ferreira [1],
[1] CERN, Geneva, Switzerland

A new electrochemical polishing facility will be built at CERN to process copper radiofrequency structures and this in the framework of the Future Circular Collider study. This polishing installation will be designed and assembled so that the necessary working conditions to achieve the ... Read More

A Computational Study of Stoichiometry Sensitivity of a PEM Fuel Cell with Multi-Parallel Flow Channels

M. A. Rahman [1], J. M. Mora [2], P. A. Chuang [1],
[1] School of Engineering, University of California, Merced, CA, USA
[2] University of the Philippines - Diliman, Quezon City, Philippines

Flow channel design in a PEM fuel cell plays a critical role for uniformly distributing reactants to the reaction sites and effectively removing product water to prevent flooding. Simplistic design and uniform reactant distribution make parallel channels a potential candidate for ... Read More

Simulation of Neurotransmitter Sensing by Cyclic Voltammetry under Mechanical Motion of a Neural Electrode

S. Han [1], M. Polanco [2], S. Bawab [2], H. Yoon [1]
[1] Norfolk State University, Norfolk, VA, USA
[2] Old Dominion University, Norfolk, VA, USA

Neural electrodes for sensing neurotransmitters are embedded within the brain, detecting electrical signals produced by kinetic reaction of neurotransmitters in the brain. Sensing utilizes cyclic voltammetry (CV), which applies sweeping potentials to identify chemical kinetics of ... Read More

A Phase Field Model for Lithium Ion Battery Particles

R. Painter [1], L. Sharpe [2], S. K. Hargrove [2],
[1] Department of Civil Engineering, Tennessee State University, Nashville, TN, USA
[2] Department of Mechanical Engineering, Tennessee State University, Nashville, TN, USA

In this study, a three-dimensional (3-D) phase field model was developed to better understand the parameters impacting the LiFePO4 cathode material in lithium ion batteries. LiFePO4 has a strong tendency to separate into stable high Li+ concentration and low Li+ concentration phases, ... Read More

Effect of Mass Flow Induced by a Reciprocating Paddle on Electroplating

M. Fukukawa [1], L. Tong [1],
[1] Keisoku Engineering System Co. Ltd., Tokyo, Japan

The reciprocating paddle electrochemical plating cells have been widely applied in microelectronics industry [1-2].The reciprocating paddle is often driven over a cathode aspect horizontally by oscillation set outside a plating cell. The paddle reciprocating parallel to a plating side ... Read More
