Limited storage capacity per unit volume restricts the physical footprint and efficiency of thermal systems. Overcoming this bottleneck allows for more compact and scalable energy storage architectures.

Suboptimal spatial arrangement of storage materials leads to excessive footprint and low capacity per unit volume. Maximizing packing density through precise stacking and winding reduces system bulk and material waste.

Insufficient energy density and storage duration limit the reliability of heat recovery systems. Increasing containment capacity ensures stable energy supply during peak demand periods.
