Application Domains
1. Energy Storage & Thermal Regulation
Modern thermal management systems demand safe, recyclable, and cost-effective materials that can reliably store and release heat. Traditional phase change materials (PCMs) like paraffin or salt hydrates often suffer from toxicity, flammability, or poor cycle stability. Sodium acetate, with its reversible crystallization process and high latent heat capacity, provides a safer, more environmentally friendly alternative for applications like heat packs, battery insulation, and smart building envelopes.
Research Frontlines:
● Development of long-cycle, non-toxic PCMs
● Hybrid sodium acetate-PCMs for smart packaging and wearables
● Thermoregulation for grid-integrated renewable storage
