A simple diffusion-limited model is presented to explain the capacity
limitations of an actual 3 volt rechargeable lithium/polymer electroly
te/lithium manganese dioxide cell at low to moderate discharge rates.
Chemical diffusion coefficients of lithium in lithium manganese dioxid
e, on the order of 10(-12)-10(-14) cm(2)/sec were determined for the t
emperature range of -10-40 degrees C. (C) 1998 Published by Elsevier S
