To investigate the cycle life capabilities of lithium iron phosphate based battery cells during fast charging, cycle life tests have been carried out at different constant charge current rates. The experimental analysis indicates that the cycle life of the battery degrades the more the charge current rate increases.
Following this research, Kassem et al. carried out a similar analysis on lithium iron phosphate based batteries at three different temperatures (30 °C, 45 °C, 60 °C) and at three storage charge conditions (30%, 65%, 100% SoC). They observed that the capacity fade increases faster with the storage temperature compared to the state of charge .
1. Introduction Lithium iron phosphate (LiFePO 4) is one of the most significant and promising cathode materials with high theoretical capacity (170 mAh·g −1 ), high thermal stability, low cost, environmental benignity and cycling stability [1], [2], [3], [4], [5].
Fig. 14 shows that the cycle life of a battery is strongly dependent on the applied charging current rate. The cycle life of the battery decreases from 2950 cycles to just 414 at 10 It. From this analysis, one can conclude that the studied lithium-ion battery cells are not recommended to be charged at high current rates.
Ning et al. reported that the fast capacity degradation of the battery at high discharge current rates is due to the change in the carbon structure . This has been illustrated based on a number of cycle life tests at 1 It, 2 It and 3 It, showing capacity degradations after 300 cycles of 9.5%, 13.2% and 16.9% respectively.
