Under a high discharge current of 10 C, LiFe0.9 Mg0.1 PO4 showed similar capacity as LiFe0.9 Co0.1 PO4 (90 mA h g−1 ), but higher than that of LiFe0.9 Ni0.1 PO4 (82 mA h g−1 ) [8]. Fe-site doping probably weakens the Li–O interaction, resulting in high ionic mobil- ity and diffusion coefficient [8]. Though the extremely flat charge–discharge profile is categorized as typical of two-phase reaction systems, which is the key feature of the LiFePO4 cath- ode, only few researchers have discussed the importance of phase transformation in LiFePO4 during charge–discharge pro- cess [7–10]. For the charge–discharge simulation of LiFePO4 ,
a core–shell reaction scheme has been applied, assuming a shrinking core with the movement of the Liα FePO4 (heterosite phase)–Li1−β FePO4 (triphylite phase) interface [10–13], where the values of α and β are both approximately 0.03–0.04 [9].
a core–shell reaction scheme has been applied, assuming a shrinking core with the movement of the Liα FePO4 (heterosite phase)–Li1−β FePO4 (triphylite phase) interface [10–13], where the values of α and β are both approximately 0.03–0.04 [9]. 对于LiFePO4的充放电模拟来说,已经采用了一种核-壳反应方案,假设核随着Liα FePO4(磷铁锰矿相)-Li1−β FePO4(磷铁锂矿)界面的运动而收缩【10-13】,这里的α和β的值都在大约0.03-0.04【9】。
一个核-壳反应方案已应用,假设萎缩的核心与运动的LiαFePO4(heterosite阶段)-Li1β(triphylite FePO4−)接口(10 - 13),在那里的价值观和βα都大约3000 - 0.04[9]。
1核壳反应计划已经实施,呈现出萎缩的核心与运动Liα FePO4 ( heterosite阶段) , Li1 - β FePO4 ( triphylite阶段)接口[ 10月13日] ,其中的价值观念α和β都约0.03-0.04 [ 9 ] 。

根据高放电电流的10 ć , LiFe0.9 Mg0.1磷酸显示,类似的身份LiFe0.9 Co0.1磷酸(九十〇毫安汞- 1 ) ,但高于LiFe0.9 Ni0.1磷酸( 82毫安汞- 1 ) [ 8 ] 。铁网站兴奋剂可能削弱李氧相互作用,从而导致高离子美孚性和扩散系数[ 8 ] 。虽然极其平坦充放电配置文件归类为典型的两相反应体系,这是关键特征LiFePO4的蛋白酶模式,只有少数的研究人员讨论的重要性,相变过程中LiFePO4的充放电过程[ 7-10 ] 。在充放电模拟LiFePO4的,
