Safe energy-storage mechanical metamaterials via architecture design

Mechanical and functional properties of metamaterials could be simultaneously manipulated via their architectures. This study proposes multifunctional possessing both load-bearing capacity energy storage capability, comprising multi-phase lattice metamaterial cylindrical battery cells. Defect phase are incorporated into the metamaterials, which then printed with stainless steel powder. The assembled cells compressed. Experimental results revealed that voids in guide deformation mode away from internal cell postponed emergence short-circuit. Effects void pattern content discussed by simulation. We found system absorb greater after defect incorporation, as designed proper content. Also, these findings further validated for six demonstrated how to design an energy-storage enhanced mechanical safety simultaneously. engineering was helpful protection absorption system.
