Abstract
The capacity of pure LiFePO4 faded gradually from initial 149 mAh gâ1-117 mAh gâ1 under current density of 30 mA gâ1 at room temperature after 60 cycles. Some obvious cracks are observed in LiFePO4 particles after cycling. The formation of cracks would lead to poor electric contact and capacity fading. A possible mechanism is proposed for the appearance of the cracks.
