Improving the Properties of Sweeteners for Enhanced Thermal Energy Storage

A solution to enhance the thermal energy storage of sugar alcohols has been developed by researchers from Tokyo Tech. They achieved this by confining sugar alcohols, commonly used sweeteners, in the pores of a covalent organic framework (COF), effectively resolving the long-standing problem of supercooling that degrades the stored thermal energy. This innovative material can store-and-release heat much more efficiently, potentially opening doors to novel, eco-friendly solid-state heat storage materials.
