Comparison between computer simulations and experimental data for high-rate discharges of plastic lithium-ion batteries

Computer simulations are compared with experimental data for Bellcore PLION® cells using the graphite/1 M LiPF6 in EC:DMC (2:1)/LiMn2O4 system. The motivation is to model lithium-ion polymer cells having higher active material loadings and competitive energy densities and specific energies to liquid lithium-ion batteries. Cells with different electrode thickness, initial salt concentrations, and higher active material loadings were examined using the mathematical model to understand better the transport processes in the plasticized polymer electrolyte system. A better description of the ionic conductivity is employed based on new conductivity data.
