Why is it Important to Measure Battery''s Internal Resistance?
The internal resistance of a battery gradually increases as it is used. The power from a battery comes from the chemical reaction between the electrolytes and the electrodes. However, over a long period of time, the chemical reaction will slow down due to rust and corrosion inside the electrodes.
Properties that decrease the internal resistance are normally thin battery domains, high porosities, and small active material particles. A battery with the opposite design features has high internal resistance, but can due …
