To determine Li+ ion diffusivity in LiFe0.9 Mg0.1 PO4 , current–transient response of LiFe0.9 Mg0.1 PO4 was tested using potential-step chronoamperometry (PSCA) measurement. Fig. 5 shows the current–transient curves for LiFe0.9 Mg0.1 PO4 obtained by potential-step from open-circuit potential (OCP) 3.6 to 3.1 V, and from OCP 3.1 to 3.48 V, in which the phase trans- formation between LiFe0.9 Mg0.1 PO4 and Li0.1 Fe0.9 Mg0.1 PO4 took place. The current decayed rapidly in both cases, although the initial current and decay rate are different for the two poten- tial jumps (Fig. 6a). The slightly higher current for discharge
(from 3.6 to 3.1 V) than that for charge (from 3.1 to 3.48 V) is probably due to large potential jump (0.5 V) in the discharge. A current hump was found for each potential jump after an ini- tial rapid decay of the current. The presence of these current humps is the characteristic of nucleation in the phase transfor- mation [19,21], which s

To determine Li+ ion diffusivity in LiFe0.9 Mg0.1 PO4 , current–transient response of LiFe0.9 Mg0.1 PO4 was tested using potential-step chronoamperometry (PSCA) measurement. 为了确定锂离子在LiFe0.9 Mg0.1PO4中的扩散，LiFe0.9 Mg0.1PO4的电流瞬态响应用电位阶跃计时电流（PSCA）测量法进行了测试。Fig. 5 shows the current–transient curves for LiFe0.9 Mg0.1 PO4 obtained by potential-step from open-circuit potential (OCP) 3.6 to 3.1 V, and from OCP 3.1 to 3.48 V, in which the phase trans- formation between LiFe0.9 Mg0.1 PO4 and Li0.1 Fe0.9 Mg0.1 PO4 took place. The current decayed rapidly in both cases, although the initial current and decay rate are different for the two poten- tial jumps (Fig. 6a). 图5示出了开路电位（OCP）从3.6到3.1V，及OPC从3.1到3.48V由电位阶跃得到的LiFe0.9 Mg0.1PO4的电流瞬态曲线，其中，LiFe0.9Mg0.1PO4和Li0.1Fe0.9Mg0.1PO4之间发生了相变。在两种情况下，电流都迅速衰落，不过对与两种电位跃进来说初始电流和衰落速率是不同的（图6a）。The slightly higher current for discharge (from 3.6 to 3.1 V) than that for charge (from 3.1 to 3.48 V) is probably due to large potential jump (0.5
