THEORETICAL DESIGN OF PRIMARY AND SECONDARY CELLS PART II – EFFECT OF POLARIZATION AND INTERNAL RESISTANCE ON CELL CHARACTERISTICS AND CELL DESIGN

摘要

An uneven current density distribution in a battery may have a large number of undesirable effects on its characteristics, particularly at high current densities. This distribution is a function of the dimensionless factor VH, where H is the electrode height and V is the square root of the ratio of the grid resistance to the electrolyte resistance. The factor VH is also related mathematically to E, the potential drop when a load is allied to the battery.nThe problems of optimum cell design are discussed which involve these and other factors.
