High-resolution simulated metal hydride pressure-concentration-temperature isotherm data with software

• Simulation data of five metal hydrides. • Data is high-resolution with several thousand datapoints each. • Simulation data is experimentally validated. • Working isotherm model simulation scripts. This article reports high-resolution data of T1.15Fe and V75Ti10Zr7.5Ni7.5 hydride-forming metals specifically. However, the data for LaNi4.8Sn0.2, LaNi4.9Sn0.1, and La0.8Ce0.2Ni5 have also been shared in the same repository. The data was generated using a model published by Lototskyy in 2016 and a computational solving method published by Faurie & Premlall in 2025. From this, MATLAB scripts were generated and used to generate the high-density isotherm data for dissemination. This article aims to make the high-resolution isotherm data and associated MATLAB scripts for segment calculations available to the broader scientific community. Sharing the isotherm data eliminates the need for the regeneration of the isotherm data for the specific metal hydrides. Furthermore, it enables the possible development of models by providing a larger dataset to consider. Especially for the future generation of metal hydride neural network isotherm models, which require large datasets.
