Description
Martyna Szatkowska and Kinga Pielichowska build heat storing materials from a sugar alcohol and starch in a 2024 paper. The alcohol, dulcitol, stores near twice the heat of like materials when it melts, and it is cheap. Its flaw is the melt itself, which changes volume and can sink added particles.
The pair set the alcohol in a starch gel so the form holds through the phase change. A half and half mix gave the strongest cold crystallization heat, a trait prized for long term storage. Heat tests showed all mixes stayed stable well past their working point. The authors pitch the systems as low cost, long life heat batteries.
