(a) Detailed XRD patterns and the first discharge and second charge curves (right). (b) Time-resolved XRD patterns at the end of the first discharge state at different current densities. “Relaxed” represents the pattern of the sample relaxed for 1 day after 10 C charge and discharge cycles.^[55](c) Phase transition model of Li_xFePO₄.^[56]
