  • Influence of Some Design Variables on the Thermal Behavior of a Lithium‐Ion Cell
    Journal of The Electrochemical Society, 1999
    Co-Authors: Gerardine G. Botte, Bradley A. Johnson, Ralph E. White
    Abstract:

    A mathematical model that includes an Anode (Carbon) decomposition reaction has been used to predict the temperature of a lithium-ion cell during medium- and high-rate discharge conditions. This work describes how various design parameters and the activation energy for the decomposition reaction of the Anode (Carbon) affect the predicted temperature of a Li{sub x}C{sub 6}/Li{sub y}NiO{sub 2} cell. The predicted results show that the particle size in the negative electrode (assumed here to be petroleum coke) is an important parameter for predicting the temperature of the cell.

  • Influence of some design variables on the thermal behavior of a lithium-ion cell

    Co-Authors: Gerardine G. Botte, Bradley A. Johnson, Ralph E. White
    Abstract:

    A mathematical model has been used to investigate the thermal characteristics of a lithium-ion cell during medium and high rate discharge conditions. The model includes an Anode (Carbon) decomposition chemical reaction in addition to the ohmic heat, the heat relieved to the ambient and the sensible heat. This work describes how various design parameters affect the predicted heating rate of a Li x C 6 /Li y NiO 2 cell, and presents the critical value of the activation energy for the decomposition reaction of the Anode (Carbon) that may cause a significant rise in the temperature of the cell. The predicted results show that the particle size in the negative (Osaka Gas Mesophase Microbead MCMB 25-10 petroleum coke) electrode is an important parameter in the heating rate of the cell for high and moderately high discharge rates in the system described.

  • Evaluation of biomass and its thermal decomposition products as fuels for direct Carbon fuel cells
    Biomass and Bioenergy, 2019
    Co-Authors: Jizhou Dong, Junquan Wang, Hong Yao
    Abstract:

    Abstract Direct Carbon fuel cell (DCFC) with biomass as fuel is a promising power generation technology due to the high efficiency of DCFC system and renewability of biomass. This study aims to find the relationship of electrochemical performance between biomass and its thermal decomposition products, and also to reveal their degradation mechanisms during durability tests in solid oxide fuel cells. The thermochemical properties of biomass and biochar, the electrochemical behaviors of biomass, biochar and biogas were characterized comprehensively, and subsequently the degradation process of biomass, biochar and biogas fueled cells were analyzed. The results showed that raw biomass fueled cells produced considerable peak power density (PPD, 0.144 W cm−2 at 1123 K) but experienced rapid discharge degradation. Torrefaction pretreatment (573K) of raw samples compromised PPDs while pyrolysis pretreatment (973K) enhanced PPDs. The electrochemical performance of raw biomass was the combined electrochemical contribution of its decomposition products (biochar and biogas). With biochar as fuel, the power was generated from CO electro-oxidation and biochar-CO2 gasification. Feeding of CO2 into the Anode chamber continuously did not improve the output performance. The discharge degradation was mainly caused by the gradually decreasing gasification reactivity of biochar with CO2 and slight Anode Carbon deposition. With biogas as fuel, the Anode reactions were electro-oxidation of active species like H2, CO, CH4, and the cell degraded due to severe Carbon deposition. Biomass, biochar and biogas fueled cells all suffered from Anode Carbon deposits, most of which were in the form of graphitic Carbon.

  • Integrating engineering design improvements with exoelectrogen enrichment process to increase power output from microbial fuel cells
    Journal of Power Sources, 2009
    Co-Authors: Abhijeet P. Borole, Choo Hamilton, Tatiana A. Vishnivetskaya, David J. Leak, Calin Andras, Jennifer L. Morrell-falvey, Martin Keller, Brian H. Davison
    Abstract:

    Microbial fuel cells (MFC) hold promise as a green technology for bioenergy production. The challenge is to improve the engineering design while exploiting the ability of microbes to generate and transfer electrons directly to electrodes. A strategy using a combination of improved Anode design and an enrich- ment process was formulated to improve power densities. The design was based on a flow-through Anode with minimal dead volume and a high electrode surface area per unit volume. The strategy focused on promoting biofilm formation via a combination of forced flow through the Anode, Carbon limitation, and step-wise reduction of external resistance. The enrichment process resulted in development of exoelec- trogenic biofilm communities dominated by Anaeromusa spp. This is the first report identifying organisms from the Veillonellaceae family in MFCs. The power density of the resulting MFC using a ferricyanide cath- ode reached 300 W m −3 net Anode volume (3220 mW m −2 ), which is about a third of what is estimated to be necessary for commercial consideration. The operational stability of the MFC using high specific surface area electrodes was demonstrated by operating the MFC for a period of over four months. Published by Elsevier B.V.
