On the use of lithium batteries at high power pulses discharge rates

This paper deals with the use of Lithium Batteries at high pulses discharge rate. The use of a commercial nanophosphate-based ultra high power Li-Ion cell discharged by high current pulses is analyzed by means of an ad - hoc experimental setup. Main cell parameters like nominal capacity, internal impedance, discharge efficiency are measured and discussed. An ad - hoc test procedure and a new strategy for defining the 'end of test' condition are presented and discussed in order to specify a stress-relieving condition for the battery during high pulsed power applications.
