Experimental Thermodynamics and Phase Relations of New Electrode Materials for Li-Ion-Batteries Studies in the systems Li-Sb-Sn, Cu-Li-Sb, Li-Si, and Li-Si-O

锂离子电池长期以来一直被认为是一种有效的储存电能的方法。然而，为了在电动汽车应用中使用，这些电池必须满足几个设计标准，例如充电/放电循环次数，能量密度和安全性。spp1473“WeNDeLIB”的范围是系统地研究用于阴极、阳极、电解质和分离器的各种材料之间的相互作用。相关系统的构成已被公认为了解整个装配性能的重要问题。虽然实验工作不能免除，但很明显，由于这些系统中存在大量的成分，它们的热力学建模是可取的。然而，CALPHAD是一种半经验方法，需要热力学数据和相平衡信息作为输入。

Li-Ion batteries have for long been recognized as an efficient way to store electric energy. For use in electro mobility applications, however, these batteries have to meet several design criteria, such as number of charge/discharge cycles, energy density and safety.The scope of SPP 1473 “WeNDeLIB” is the systematic investigation of materials interaction between the various materials used for cathode, anode, electrolyte and separators. The constitution of the relevant systems has been recognized as an important issue to understand the performance of the whole assembly. While experimental work cannot be dispensed with, it is clear that due to the high amount of components present in these systems, their thermodynamic modeling is desirable. CALPHAD, however, is a semi empirical method that requires thermodynamic data and phase equilibrium information as an input.
