摘要:

大规模电气化对于应对气候危机至关重要,但要使化学工业和交通运输完全电气化,仍存在一些科学和技术挑战。在这两个领域,新的电化学材料将是至关重要的,但它们的发展目前严重依赖于人力时间密集型实验试错和计算昂贵的第一原理,介观尺度和连续模拟。我们提出了一个自动化的工作流程,AutoMat,通过引入自动化的输入生成和跨尺度的模拟管理,从第一原理到连续体器件建模,加速了这些计算步骤。此外,我们还展示了如何无缝集成多保真度预测,如机器学习代理或自动机器人实验“在环”。自动化框架与设计空间搜索技术一起实现,以通过隐式学习优化多个指标的器件性能的设计功能来显着加速整个材料发现管道。我们讨论了AutoMat的好处,使用电催化和能量存储的例子,并强调经验教训。

英文摘要:

Large-scale electrification is vital to addressing the climate crisis, but several scientific and technological challenges remain to fully electrify both the chemical industry and transportation. In both of these areas, new electrochemical materials will be critical, but their development currently relies heavily on human-time-intensive experimental trial and error and computationally expensive first-principles, meso-scale and continuum simulations. We present an automated workflow, AutoMat, that accelerates these computational steps by introducing both automated input generation and management of simulations across scales from first principles to continuum device modeling. Furthermore, we show how to seamlessly integrate multi-fidelity predictions such as machine learning surrogates or automated robotic experiments "in-the-loop". The automated framework is implemented with design space search techniques to dramatically accelerate the overall materials discovery pipeline by implicitly learning design features that optimize device performance across several metrics. We discuss the benefits of AutoMat using examples in electrocatalysis and energy storage and highlight lessons learned.
