Researchers have sought for standards, methodologies and procedures to properly measure the thermal properties of Thermal Energy Storage (TES) materials. Among them, thermal conductivity plays a key role in the TES system design as it dictates the charging/discharging dynamics of a TES system.
Existing materials research has accumulated a large number of constitutive relationships between structure and performance, so ML can facilitate the construction of datasets and selection of features. The prospect of using ML to predict the structure of energy storage materials is very promising.
The energy storage performance of energy storage materials is closely related to their structure. For example, the variable structure and wide variety of morphologies make carbon an ideal electrode material for energy storage.
Structural prediction Currently, the dominant method for predicting the crystal structure of energy storage materials is still theoretical calculations, which are usually available up to the atomic level and are sufficiently effective in predicting the structure.
Owing to the capability of characterizing spin properties and high compatibility with the energy storage field, magnetic measurements are proven to be powerful tools for contributing to the progress of energy storage.
