Reasonable measurement and optimization of internal resistance are essential to improving battery performance and service life. The internal resistance of lithium batteries directly affects their charge and discharge performance, energy conversion efficiency, and service life.
The internal resistance of Lithium-ion batteries, as a key physical parameter, limits both the efficiency of fast-charging and the performance of high-power energy storage systems, and development of efficient strategies to reduce internal resistance has become a key focus for recent research.
Internal resistance is simply the inherent resistance of a battery to the flow of electrons. Current flowing through a battery causes some of the energy to be lost within the battery owing to this resistance. This means that the external circuit gets a lesser voltage.
Different internal resistances exist for lithium-ion, lead-acid, and nickel-cadmium batteries. Old battery usually have more internal resistance. Cold temperatures often raise internal resistance. Internal resistance changes with the state of charge; it depends on how full or empty the battery is.
