Origami Tribo-Metamaterials with Mechanoelectrical Multistability

“…Since origami metamaterials are significantly dependent on their origami cells, well tunability over mechanical properties can be induced by rationally designing those cells. , Studies have been conducted on designing origami cells to obtain the origami metamaterials with desirable configurations, − unprecedented mechanical properties, such as negative Poisson’s ratio, − negative stiffness, , and advanced functions. , Recent research interests have been shifted to exploring the functionality of mechanical metamaterials using functional materials, such as energy materials for energy generation, power absorption, , energy storage, thermal materials for thermophotovoltaic response, thermomechanical response and thermoelastic response, , magnetic materials for electromagnetic energy harvesting and absorption, − and so forth. Recent development of advanced functional materials (e.g., self-healable materials, , nanomaterials, , etc.) has expanded the extraordinary characteristics of mechanical metamaterials to promising mechanoelectrical performance, − which has led to the future direction of mechanical functional metamaterials. − The integration of energy materials with structural materials at the multiscale, mechanical functional metamaterials is expected to achieve promising mechanical properties and well excitation sensitivity, , as well as enhanced electrical performance such as high-energy conversion efficiency, which have opened an exciting venue for efficiently sensing and energy harvesting.…”

Incorporating Binary Metal Oxides in Poly(ethylene oxide)-Based Solid Electrolytes by Vapor Phase Infiltration

“…To overcome these challenges, additives are usually introduced to the solid polymer electrolytes and the ideas of gel polymer electrolytes (GPEs) , and composite solid polymer electrolytes (CSPEs) − are proposed. After incorporating liquid solvents into the polymer, GPEs show greatly improved ionic conductivities and have been successfully applied to Li and post-Li batteries. − In addition to the liquid solvents, plastic crystals have been incorporated into the polymer, which not only increased the ionic conductivity but also enhanced the electrochemical stability against nickel-rich NCM (LiNi x Co y Mn 1– x – y O 2 , x ⩾ 0.5) cathodes. , However, the high ionic conductivity is obtained at the expense of mechanical strength, which may cause safety hazards. Thus, the incorporation of inorganic fillers into the polymer matrix to fabricate composite solid polymer electrolytes (CSPEs) has attracted widespread attention.…”

Recycling of All‐Solid‐State Li‐ion Batteries: A Case Study of the Separation of Individual Components Within a System Composed of LTO, LLZTO and NMC**

“…[4] Within the ASSBs, both organic and inorganic electrolytes are of interest. As organic electrolytes, polymer electrolytes based on polyethylene oxide (PEO), [5] polyacrylonitrile (PAN), [6] polycaprolactone (PCL), [7] poly(methyl methacrylate), [8] have gathered wide spread interest due to favorable mechanical properties and partial self-healing capabilities. [9] On the other hand, inorganic electrolytes [10] based on sulfides [11] and oxides are of interest due to their high ionic conductivity and high lithium ion transference number.…”
