Ageing Characterization of Li-Ion Batteries Discharged at High Pulse Current Rates

This paper deals with the use of commercial Nanophosphate™ based Li-Ion cells at high power pulse discharge rates. An ad-hoc experimental setup allows for repeating in an automatic way a series of pulse tests on the cell with discharge currents up to 100C-rate, being C the nominal capacity of the cell. Characterization of cell ageing and State of Health (SOH) behavior during current pulses is discussed throughout the paper
