This paper reports on the supramolecular self-assembly of cyclopentano cucurbit[5]uril (CyP5Q[5]), L-phenylalanine (L-Phe), and cadmium ions. The crystal structure is characterized using X-ray diffraction. The results show that the complex belongs to a monoclinic system with P21 space group. Cd2+ and L-Phe are coordinated in two CyP5Q[5] portals via hydrogen bonds and ion-dipole interactions, respectively, so that the outer wall of the cucurbit[n]uril forms a porous channel. Each channel consists of six supramolecular chains, which may accommodate inorganic anions, such as CdCl $$_{4}^{{2 - }}$$ .

The solid-state reaction was employed to obtain LiBOB in vacuum dryer at 100°C, with the dryer of P2O5. The resulting LiBOB was employed in various ternary solvent blends to get the k, and its change with salt, solvent composition and temperature. 0.7 M LiBOB-PC/EMC/DMC (1: 1: 1, v: v: v) and 0.5 M LiBOB-EC/EMC/DMC (1: 1: 1, v: v: v) were observed to have better k at wide θ range, and the former was chosen to assemble Li/MCMB and LiFePO4/Li cells. The results indicated that it can stabilize the MCMB anodes, and exhibit good stability in LiFePO4/Li cell.
