Mathematical Model of a Lithium/Thionyl Chloride Battery

Description: A mathematical model of a spirally wound lithium/thionyl chloride primary battery has been developed ~d used for parameter estimation and design studies. The model formulation is based on the fimdarnental Consemation laws using porous electrode theory and concentrated solution theory. The model is used to estimate the difision coefficient and the kinetic parameters for the reactions at the anode and the cathode as a function of temperature. These parameters are obtained by fitting the simulated… more

Progress report on the evaluation of porous cathode for the electrochemical reduction of nitrates and nitrites in liquid wastes

Description: This report describes the experimental and modeling work performed to evaluate porous cathodes for the electrochemical reduction of nitrites in liquid wastes. The experiments were done using the MP{dagger} cell with two different porous cathodes: nickel foam and TySAR{trademark}SB{double_dagger}. The experimental results are compared with each other and to those obtained with a planar nickel cathode. The results show that the ammonia production reaction is the dominant cathodic reaction ({appro… more

A simple model of the batch electrochemical reduction of nitrate/nitrite waste

Description: A model of a divided parallel plate electrochemical cell operated in a batch mode for the destruction of NO{sub 3}{sup {minus}}/NO{sub 2}{sup {minus}} in alkaline waste streams is presented.
