Abstract
The native oxide layer of Ca-metal electrodes impedes Ca-ion transport properties across the electrolyte–electrode interphase. Bis(trifluorosulfonyl)imide-salts (TFSI-) were reported to inhibit any ion transport due to facile degradation at the reactive interface. Poly(ethylene oxide)-based solid polymer electrolytes (SPEs) frequently use Ca(TFSI)2 for its comparatively high ionic conductivity and hence have not achieved reversible plating/stripping from Ca-electrodes yet. To overcome this roadblock, a Ca-electrode surface treatment with Bi-salt was introduced, enabling operation of Ca/Ca symmetrical cells from a PEO-Ca(TFSI)2 SPE for the first time. The functionalization greatly reduced interfacial resistances thus allowing reversible Ca plating and stripping from the Ca-SPE.
期刊介绍：
ACS Applied Polymer Materials is an interdisciplinary journal publishing original research covering all aspects of engineering, chemistry, physics, and biology relevant to applications of polymers.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates fundamental knowledge in the areas of materials, engineering, physics, bioscience, polymer science and chemistry into important polymer applications. The journal is specifically interested in work that addresses relationships among structure, processing, morphology, chemistry, properties, and function as well as work that provide insights into mechanisms critical to the performance of the polymer for applications.
