Complex Hydride-Based Gel Polymer Electrolytes for Rechargeable Ca-Metal Batteries.

ABSTRACT: Rechargeable Ca batteries offer the advantages of high energy density, low cost, and earth-abundant constituents, presenting a viable alternative to lithium-ion batteries. However, using polymer electrolytes in practical Ca batteries is not often reported, despite its potential to prevent leakage and preserve battery flexibility. Herein, a Ca(BH₄)₂-based gel-polymer electrolyte (GPE) is prepared from Ca(BH₄)₂ and poly(tetrahydrofuran) (pTHF) and tested its performance in Ca batteries. The electrolyte demonstrates excellent stability against Ca-metal anodes and high ionic conductivity. The results of infrared spectroscopy and ¹H and ¹¹B NMR indicate that the terminal ─OH groups of pTHF reacted with BH₄ ^-
