Solid-state electrolytes provide substantial improvements to safety and electrochemical stability in lithium-ion batteries when compared with conventional liquid electrolytes, which makes them a promising alternative technology for next-generation high-energy batteries. Currently, the low mobility of lithium ions in solid electrolytes limits their practical application. The ongoing research ove...

Novel ionic liquid polymer electrolytes based on polymer poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP), lithium bis(tri-fluoromethanesulfonyl)imide (LiTFSI) with different 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (EMITFSI) weight ratios have been synthesized and applied to quasi-solid state Li–air batteries. The morphology, electrochemical properties of prepa...

Rechargeable, all-solid-state Li ion batteries (LIBs) with high specific capacity and small footprint are highly desirable to power an emerging class of miniature, autonomous microsystems that operate without a hardwire for power or communications. A variety of three-dimensional (3D) LIB architectures that maximize areal energy density has been proposed to address this need. The success of all ...

All-Solid-State Batteries In article number 2206762, Yijie Liu, David Mitlin, and co-workers report a stable anode-free all-solid-state battery (AF-ASSB) with sulfide-based solid-electrolyte (argyrodite Li6PS5Cl). The is achieved by tuning the wetting of lithium metal on “empty” copper current-collector. cover image, sprinting antelope represent cations rapidly diffusing through solid-state sul...

Polymer solid state electrolytes are actively sought for their potential application in energy storage devices, particularly lithium metal rechargeable batteries. Herein, we report a polymer with high concentration salts as a quasi-solid state electrolyte used for lithium-sulfur cells, which shows an ionic conductivity of 1.6 mS cm(-1) at room temperature. The cycling performance of Li-S batter...

Highly reversible oxygen redox chemistry of Li 2 RuO 3 enabled by a stabilizing electrode–electrolyte interphase with sulfide solid electrolyte.

Silicon is an attractive material for anodes in energy storage devices, because it has ten times the theoretical capacity of its state-of-the-art carbonaceous counterpart. Silicon anodes can be used both in traditional lithium-ion batteries and in more recent Li-O2 and Li-S batteries as a replacement for the dendrite-forming lithium metal anodes. The main challenges associated with silicon anod...

It was observed that the ionic conductivity of the solid-state electrolyte LiI/3-hydroxypropionitrile (HPN) = 1:4 (molar ratio) decreased dramatically with increasing iodine (I(2)) concentration, which differs from the conduction behavior of the Grotthuss transport mechanism observed in liquid or gel electrolytes. The short-circuit photocurrent density (J(sc)) of the dye-sensitized solar cell (...

Fuel cells convert chemical energy directly into electrical energy with high efficiencies and environmental benefits, as compared with traditional heat engines. Yttria-stabilized zirconia is perhaps the material with the most potential as an electrolyte in solid oxide fuel cells (SOFCs), owing to its stability and near-unity ionic transference number. Although there exist materials with superio...
