Quasi‐Solid‐State Rechargeable Lithium‐Ion Batteries with a Calix[4]quinone Cathode and Gel Polymer Electrolyte

Abstract

Filled to capacity: Calix[4]quinone (C4Q) has eight available carbonyl groups for binding lithium ions (see picture). It can be exploited to prepare quasi‐solid‐state rechargeable lithium batteries with a poly(methyl acrylate)/poly(ethylene glycol) based gel polymer electrolyte and a LiClO4/DMSO loading. It shows an initial discharge capacity of 422 mA h g−1 and a capacity retention of 379 mA h g−1 after 100 cycles.

“…[18][19][20][21][22] However, there are still many challenges in developing high performance organic electrodes. For example, organodisulfi des and thioethers suffer from critical problems of high solubility in organic electrolytes and slow reaction kinetics of S-S and S=O bonds.…”

Polyanthraquinone-based nanostructured electrode material capable of high-performance pseudocapacitive energy storage in aprotic electrolyte

“…Recently, organic electrode materials have been proposed for energy storage applications [8][9][10][11][12]. Compared to their prevailing inorganic counterparts, organic matters as electrode materials have multifold advantages [11,12].…”

“…The quinone moiety is frequently found in many biological molecules (e.g., vitamin K), some of which play important roles as redox materials in biological electron-transport systems [14]. In the past few years, quinone-containing small molecules have been explored as the cathode materials of batteries [8,9]. Unfortunately, their low electric conductivity and dissolution in electrolytes usually pose critical rate capability and cycleability problems [8,9].…”
