Influence of surface-active bonds of carbon structures on discharge-charging processes of a current source

摘要

A study has been carried out of the effect on the discharge-charging processes of a current source of surface-active bonds of carbon structures used as additives in the composition of a negative electrode material. A mechanism has been proposed based on the conclusions derived from the Kossel-Stranski molecularkinetic theory, which explains the growth of 3PbOPbSO(4)H(2)O crystals upon the introduction of carbon materials. It has been established that the presence of carbon additives in the composition of the negative electrode material of starter lead-acid batteries increases the capacitance of 20-h discharge mode by up to 5% and the discharge duration by cold scrolling current to a final voltage of 6 V at negative temperatures of-18A degrees C and-30A degrees C by 3-4.5% and 9-13%, respectively.
