Original Abstract
It has been established that addition of carbon additives to the negative active material of lead-acid batteries increases battery charge acceptance in hybrid electric vehicle mode of operation (1). But the latest findings show that the titanium dioxide has similar effect (2). Hence this paper deals with impedance characteristics of experimental lead-acid accumulators with various amounts of titanium dioxide in active mass of negative electrodes. Electrochemical impedance spectroscopy was used for all measurements. Obtained data was subsequently fitted by equivalent circuits. It was investigated that ohmical resistivity of lead-acid cell increases with higher amounts of titanium dioxide in active mass of negative electrodes.
Keywords
Electrochemical impedance spectroscopy, lead-acid accumulator, titanium dioxide.
