Fast Li+ solid ion conductors are a key component of all-solid-state batteries, a technology currently under development. The possible use of metallic lithium as active material in solid-state batteries warrants a quantum step improvement of battery specific energy, enabling further electric vehicles application. Hereby, we report the synthesis and ion conduction properties of a new solid hybrid electrolyte based on the MIL-121 metal organic framework (MOF) structure. After an ion exchange procedure that introduces Li+ in the structure, a known quantity of a soaking electrolyte is incorporated. The soaking electrolyte is based on the EMIM-TFSI ionic liquid, thus we can classify our formulation as a MOF–ionic liquid hybrid solid electrolyte. Electrical conductivity is investigated by impedance spectroscopy and preliminary studies of ion dynamics are conducted by 7Li NMR. The field of MOF-based ion conductors remains in incipient stages of research. Our report paves the way towards the rational design of new solid-state ion conductors.

Abstract While solid-state batteries are tantalizing for achieving improved safety and higher energy density, solid ion conductors currently available fail to satisfy the rigorous requirements for battery electrolytes and electrodes. Inorganic ion conductors allow fast ion transport, but their rigid and brittle nature prevents good interfacial contact and impedes device integration and stability. Conversely, flexible polymeric ion conductors provide better interfacial compatibility and mechanical tolerance, but suffer from inferior ionic conductivity (< 10−5 S cm−1 at room temperature) due to the coupling of ion transport with the polymer chain motion1-3. In this work, we report a general design strategy for achieving one-dimensional (1D), high-performance polymer solid-state ion conductors through molecular channel engineering, which we demonstrate via Cu2+-coordination of cellulose nanofibrils. The cellulose nanofibrils by themselves are not ionic conductive; however, by opening the molecular channels between the cellulose chains through Cu2+ coordination we are able to achieve a Li-ion conductivity as high as 1.5×10−3 S cm−1 at room temperature—a record among all known polymer ion conductors. This improved conductivity is enabled by a unique Li+ hopping mechanism that is decoupled from the polymer segmental motion. Also benefitted from such decoupling, the cellulose-based ion conductor demonstrates multiple advantages, including a high transference number (0.78 vs. 0.2–0.5 in other polymers2), low activation energy (0.19 eV), and a wide electrochemical stability window (4.5 V) that accommodate both Li metal anode and high-voltage cathodes. Furthermore, we demonstrate this 1D ion conductor not only as a thin, high-conductivity solid-state electrolyte but also as an effective ion-conducting additive for the solid cathode, providing continuous ion transport pathways with a low percolation threshold, which allowed us to utilize the thickest LiFePO4 solid-state cathode ever reported for high energy density. This approach has been validated with other polymers and cations (e.g., Na+ and Zn2+) with record-high conductivities, offering a universal strategy for fast single-ion transport in polymer matrices, with significance that could go far beyond safe, high-performance solid-state batteries.

Fast silver ion conducting glasses as electrochemical devices have been tested. A silver iodine battery using a silver ionic conducting glass (AgPO3-Ag2S-AgI) has been studied. The interaction of some gases (O2CI2, H2S) with the electrochemical chains: Pt/Sb2S3-AgI (glass)/Ag and Pt/AgCl (thin film)/Sb2S3- AgI (glass)/Ag has been investigated. Finally, the behavior of thin films of Ag2S3-Ag2S-CdS glasses as sensitive membranes for Cd detection in solution has been tested on MIS structures Au/Si/SiO2/ Membrane/Cd in solution/Reference electrode.
