在本文中,我们将处理到数据驱动的性能建模的锂基尖晶石电池材料。当考虑具有Me作为一种或多种金属的LiMe 2 O 4形式的尖晶石化合物时,假设最多三种金属元素,存在125,000种可能的组合。在这项工作中,我们专注于预测属性的容量,并通过将处理纳入建模中,将可能的组合数量增加到200万。由于工艺和性能之间的非线性关系,以及确保适当的灵敏度,一种新的方法,跟踪变化的工艺。这项工作为指导下一代电池实验提供了宝贵的工具,大大缩小了无限的设计空间。
英文摘要:
In this paper, we incorporate processing into the data driven property modeling of Li-based spinel battery materials. When considering spinel compounds of the form LiMe2O4 with Me as a metal or metals, there are 125,000 possible combinations assuming a maximum of three metallic elements. In this work, we focus on capacity for our predicted property, and increase the number of possible combinations to two million by incorporating processing into the modeling. Due to the non-linear relationship between processing and property, as well as ensuring proper sensitivity, a new approach which tracks the change with changing processing is introduced. This work provides an invaluable tool for guiding the next generation of battery experiments, providing a significant narrowing of the infinite design space.
