We have been developing computational software towards assisting in the discovery of organic-based materials with targeted structures and properties. Here, we will explore the different ways in which both artificial intelligence (AI) and molecular simulation can assist in the discovery and understanding of a variety of materials for energy devices. This will include exploration of generative AI for the discovery of ionic liquids[1,2], the use of molecular simulation and machine learning forcefields to predict the structure and ion conductivity of polymer membranes for redox flow batteries,[3,4] and the use of optimisation algorithms to accelerate the discovery of new electrode materials.
