What factors affect how quickly a battery discharges?
The outside temperature, the battery’s level of charge, the battery’s design, the charging current, as well as other variables, can all affect how quickly a battery discharges itself.
Can a battery be discharged up to 10C?
According to the battery specification reported in Table 1 this kind of cells can be discharged up to 10C. The choice to limit the current rate to 5C is due to the fact that for higher current rates the voltage drop over the internal resistance becomes comparable with the voltage range usable for the battery.
What causes self-discharge in batteries?
Beyond the kind of electrolyte solution, the chemical reactions that cause self-discharge heavily depend on battery chemistry and electrode materials. This current, which is also known as the leak current, can be represented as a shunt resistor in an equivalent circuit representation of a cell.
How does low temperature storage affect battery self-discharge?
Low temperature storage of batteries slows the pace of self-discharge and protects the battery’s initial energy. As a passivation layer forms on the electrodes over time, self-discharge is also believed to be reduced significantly.
Does charge/discharge rate affect battery aging?
In the literature, only a few papers have considered battery aging as a function of the charge/discharge current rate, but they agree that a higher current rate leads to faster battery aging. In any case, all of the tests have been conducted in a climactic chamber with a constant room temperature.
What can cause a battery to leak current?
The passage of an electric current even when the battery-operated device is turned off may be the result of leakage caused by electronically slightly conductive residues of dirt on the battery surface, the battery holder, or mechanical and chemical processes inside the battery.
