Jk. Vilhunen et J. Tummavuori, CHANGES IN THE MORPHOLOGY AND STRUCTURE OF POSITIVE ACTIVE MATERIAL OF STARTER BATTERIES AS A CONSEQUENCE OF THEIR USE IN VEHICLES, Journal of power sources, 47(1-2), 1994, pp. 189-195
The changes in the structure, morphology and composition of the positi
ve active mass of lead/acid starter batteries under normal use in vehi
cles were investigated. The softening of the active mass as a function
of the service life of the batteries was clearly seen on the basis of
the methods of analyses used in this study.
