Core Viewpoint - The research introduces a novel mechanism called "slip-enhanced close-contact melting" (sCCM) to enhance the charging rate of phase-change thermal batteries without sacrificing energy density [4][5]. Group 1 - The phase-change thermal battery utilizes materials like paraffin, hydrated salts, and sugar alcohols to store heat through phase change latent heat, but high energy density and rapid charging/discharging are typically conflicting requirements [3]. - The research team achieved a new record power density of 1100 ± 2% kW/m³ in their prototype using organic phase-change materials [5]. - The proposed strategy involves a rational design of composite coatings that facilitate sCCM, integrating a pulse heating layer to pre-melt phase-change materials and a slip interface to maintain efficient melting during charging [5]. Group 2 - The strategy is adaptable and scalable, making it applicable to various phase-change materials across a wide temperature range, thus enabling high-performance thermal energy storage [6].
