    Cationic Covalent Organic Framework Nanosheets for Fast Li-Ion Conduction

    No full text
    Covalent organic frameworks (COFs) with their porous structures that are accommodative of Li salts are considered to be potential candidates for solid-state fast Li<sup>+</sup> conductors. However, Li salts simply infiltrated in the pores of solid-state COFs tend to be present in closely associate ion pairs, resulting in slow ionic diffusion dynamics. Here we incorporate cationic skeleton into the COF structure to split the Li salt ion pair through stronger dielectric screening. It is observed that the concentration of free Li<sup>+</sup> ions in the resulting material is drastically increased, leading to a significantly improved Li<sup>+</sup> conductivity in the absence of any solvent (up to 2.09 × 10<sup>–4</sup> S cm<sup>–1</sup> at 70 °C)
