Data-Driven Analysis of High-Throughput Experiments on Liquid Battery Electrolyte Formulations: Unraveling the Impact of Composition on Conductivity

Chemistry Methods

A specially designed high-throughput experimentation facility, used for the highly effective exploration of electrolyte formulations in composition space for diverse battery chemistries and targeted applications, is presented. It follows a high-throughput formulation-characterization-optimization chain based on a set of previously established electrolyte-related requirements. Here, the facility is used to acquire large dataset of ionic conductivities of non-aqueous battery electrolytes in the conducting salt-solvent/co-solvent-additive composition space. The measured temperature dependence is mapped on three generalized Arrhenius parameters, including deviations from simple activated dynamics. This reduced dataset is thereafter analyzed by a scalable data-driven workflow, based on linear and Gaussian process regression, providing detailed information about the compositional dependence of the conductivity. Complete insensitivity to the addition of electrolyte additives for otherwise constant molar composition is observed. Quantitative dependencies, for example, on the temperature-dependent conducting salt content for optimum conductivity are provided and discussed in light of physical properties such as viscosity and ion association effects.

Autonomous Synthesis and Inverse Design of Electrochromic Polymers with High Efficiency and Accuracy

The design and synthesis of functional polymers, aimed at targeted properties through specific structures, have long been challenged by their complex and often nonlinear structure− property relationships. Key processes, including knowledge accumulation for predictive design and experimental refinement and validation, are traditionally labor-insensitive and timeconsuming, making it difficult to balance accuracy and efficiency.

Localization, inspection, and reasoning (LIRA) module for autonomous workflows in self-driving laboratories

Self-driving labs (SDLs) combine robotic automation with artificial intelligence (AI) to allow autonomous, high-throughput experimentation. However, robot manipulation in most SDL workflows operates in an open-loop manner, lacking real-time error detection and error correction. This can reduce reliability and overall efficiency.
