AI Technical Summary
Existing building energy storage materials suffer from poor electrode-electrolyte interface bonding, easy electrolyte loss, difficulty in synergizing the mechanical properties of wood with energy storage functions, and existing technical solutions are unable to meet the structural load-bearing requirements of buildings.
Hydrogel-modified wood is used as a solid electrolyte, modified magnesium phosphate cement as a conductive bonding layer, and carbon fiber cloth as an electrode to form a symmetrical layered board structure. The modified magnesium phosphate cement is used to bond the carbon fiber cloth and polymerize the hydrogel network in situ inside the wood to form a stable electrolyte and electrode combination.
It achieves synergy between the mechanical load-bearing capacity and energy storage function of wood, avoids electrolyte loss, provides a stable ion-electron conversion interface, reduces costs and simplifies the construction process, and is suitable for large-scale building applications.
