“…Figure 1d and Figure S3 (Supporting Information) show ionic conductivities of the polymer electrolytes as a function of SiO 2 and PEO content, ranging from 6.25 mS cm −1 (PE‐7‐0) to 15.3 mS cm −1 (PE‐6‐1). These values are in the same order of magnitude as the EMImCl‐AlCl 3 ionic liquid (≈19 mS cm −1 [ 37,38 ] ) and are comparatively higher than most other Al battery polymer electrolytes reported in the literature (0.25–6.61 mS cm −1 ), [ 10,11,18–20,27,28,39,40 ] owing to the high loading of ionic liquid within the electrolyte, at over 93 wt%. Similarly high ionic conductivities have been reported in polymer electrolytes with comparable ionic liquid loadings.…”

Chloroaluminate ionic liquids are commonly used electrolytes in rechargeable aluminum batteries due to their ability to reversibly electrodeposit aluminum at room temperature. Progress in aluminum batteries is currently hindered by the limited electrochemical stability, corrosivity, and moisture sensitivity of these ionic liquids. Here, a solid polymer electrolyte based on 1‐ethyl‐3‐methylimidazolium chloride‐aluminum chloride, polyethylene oxide, and fumed silica is developed, exhibiting increased electrochemical stability over the ionic liquid while maintaining a high ionic conductivity of ≈13 mS cm−1. In aluminum–graphite cells, the solid polymer electrolytes enable charging to 2.8 V, achieving a maximum specific capacity of 194 mA h g−1 at 66 mA g−1. Long‐term cycling at 2.7 V showed a reversible capacity of 123 mA h g−1 at 360 mA g−1 and 98.4% coulombic efficiency after 1000 cycles. Solid‐state nuclear magnetic resonance spectroscopy measurements reveal the formation of five‐coordinate aluminum species that crosslink the polymer network to enable a high ionic liquid loading in the solid electrolyte. This study provides new insights into the molecular‐level design and understanding of polymer electrolytes for high‐capacity aluminum batteries with extended potential limits.

“…PEA-GPE displays 𝜎 Al 3+ ≈1.46 mS cm −1 and EWs ≈3 V versus Al/Al 3+ with minimal charge-transfer resistance implying the stable Al//Al interface polarizations. [193] Further, photo-curable PTHF-Epoxy SPEs have been reported with 𝜎 Al 3+ ≈0.02 mS cm −1 . [560] Besides, to alleviate the passivation effect of native oxide and electrode disintegration that undergoes severe parasitic reactions with continuous depletion of electrolyte even for lower overpotentials, several approaches have been proposed, such as uniform protective Al oxide layer over Al-metal, interface engineering, specifically artificial SEI or buffer layers.…”

Solid‐state batteries (SSBs) have received significant attention due to their high energy density, reversible cycle life, and safe operations relative to commercial Li‐ion batteries using flammable liquid electrolytes. This review presents the fundamentals, structures, thermodynamics, chemistries, and electrochemical kinetics of desirable solid electrolyte interphase (SEI) required to meet the practical requirements of reversible anodes. Theoretical and experimental insights for metal nucleation, deposition, and stripping for the reversible cycling of metal anodes are provided. Ion transport mechanisms and state‐of‐the‐art solid‐state electrolytes (SEs) are discussed for realizing high‐performance cells. The interface challenges and strategies are also concerned with the integration of SEs, anodes, and cathodes for large‐scale SSBs in terms of physical/chemical contacts, space‐charge layer, interdiffusion, lattice‐mismatch, dendritic growth, chemical reactivity of SEI, current collectors, and thermal instability. The recent innovations for anode interface chemistries developed by SEs are highlighted with monovalent (lithium (Li+), sodium (Na+), potassium (K+)) and multivalent (magnesium (Mg2+), zinc (Zn2+), aluminum (Al3+), calcium (Ca2+)) cation carriers (i.e., lithium‐metal, lithium‐sulfur, sodium‐metal, potassium‐ion, magnesium‐ion, zinc‐metal, aluminum‐ion, and calcium‐ion batteries) compared to those of liquid counterparts.

This study explores trivalent Al interaction with aqueous starch gel in the presence of two different anions through salting effect. Salting‐out nature of Al2(SO4)3·18H2O with starch gel causes precipitation of starch; this happens due to competitive anion‐water complex formation over starch–water interaction, thereby reducing polymer solubility. Salting‐in effect of AlCl3 with starch gel happens through Al3+ cation interaction with hydroxyl group of starch and increases polymer solubility, making gel electrolyte viable for battery applications. Prepared gel electrolyte exhibits ionic conductivity of 1.59 mS cm−1 and a high tAl3+ value of 0.77. The gel electrolyte's performance is studied using two different cathodes, the Al|MoO3 cell employing starch gel electrolyte achieves discharge capacity of 193 mA h g−1 and Al|MnO2 cell achieves discharge capacity of 140 mA h g−1 @0.1 A g−1 for first cycle. The diffusion coefficient of both cells using starch gel electrolyte is calculated and found to be 2.1 × 10−11 cm2 s−1 for Al|MoO3 and 3.1 × 10−11 cm2 s−1 for Al|MnO2 cells. The Al|MoO3 cell at lower temperature shows improved electrochemical performance with a specific capacity retention of ≈87.8% over 90 cycles. This kind of aqueous gel electrolyte operating at low temperature broadens the application for next generation sustainable batteries.
