AI Customer ServiceThe age of the battery; the older the battery the less capacity it has. Cell conditions: sulfation, sediments reduce the cell voltage. Temperature: the higher the temperature the higher the capacity. Discharge rate: the higher the discharge rate, the lower the capacity. State of charge, SC: This is how much energy the battery has—measured in %.
Cell voltage is determined by the electrochemistry involved. Nickel-cadmium cells nominally produce about 1.2 volts per cell while lead-acid batteries produce about 2 volts per cell. Battery voltages then must be multiples of the basic unit. For example, nickel-cadmium battery voltages may be 1.2, 2.4, or 3.6 volts, but not 3.0 or 4.5.
Voltage, V: The voltage is a unit of measurement of electrical potential difference between any two points. It is also known as the electromotive force. The electrical potential between the anode and the cathode in the batteries is called the battery voltage. Different battery cell generate different voltages, the higher the better.
The voltage is generated by the charging and discharging process of the Li-ions from the anode and cathode. Reactions shown also apply to solid-state batteries, although the choice of material is atypical here, Own illustration. During discharge, the Li-ions migrate from the anode to the cathode. LCO is a cathode with a layered structure.
For this reason, the end-of-charge (as well as end-of-discharge) voltages need to be temperature compensated; this is especially true for power sources that can be damaged by overcharge. For example, for lead–acid batteries, the charge voltage must be decreased by 3–4 mV per cell and per 1 °C rise in temperature.
Battery voltages then must be multiples of the basic unit. For example, nickel-cadmium battery voltages may be 1.2, 2.4, or 3.6 volts, but not 3.0 or 4.5. A battery can be a single cell provided with terminations and insulation and considered ready for use.
