热力学理论揭示了表面能和界面能对间隙离子在纳米微晶中的平衡性质和溶解度极限的影响。应用于LixFePO（4），特别是界面能贡献起着重要作用，它们的作用解释了纳米结构电极中电化学测量的可溶解性间隙变窄的观察结果。
Thermodynamic theory reveals the impact of surface and interface energies on the equilibrium properties and solubility limits of interstitial ions in nanosized crystallites. Applied to LixFePO(4) especially interface energy contributions play important roles, and their effect explains observations of the narrowing of electrochemically measured miscibility gaps in nanostructured electrodes.
