“…[ 13 ] To date, only a few lithium‐conducting elastomers with high ionic conductivities have been reported. For example, elastic poly‐butyl acrylate/succinonitrile [ 14 ] (PBA/SN) and SiO 2 /poly(propylene oxide) [ 15 ] (PPO) electrolytes were fabricated via polymerization‐induced phase separation and covalent‐dynamic hydrogen bonding dual‐crosslinking method, respectively, and the corresponding solid‐state lithium metal batteries operated well at room temperature. However, most reported elastomer‐based electrolytes are either poor at lithium conducting or suffer mechanical deterioration due to gelation.…”

Elastomers offer attractive advantages over classical solid-state electrolytes in terms of ensuring stable interfacial contact and maintaining fatigue durability, but the low ionic conductivity obstructs their practical applications in long-life lithium metal batteries. In this work, rubber-derived lithium-conducting elastomer has been developed via sulfur vulcanization of nitrile butadiene rubber with a polymerizable ionic liquid to provide both high resilience and dramatically improved ionic conductivity. Owing to the chemically crosslinked network between rubber chains and ionic liquid fragments generated during vulcanization, the elastic lithium-conductor achieves high resilience of 0.92 MJ m −3 , superior cyclic durability of 1000 cycles at 50% strain, and high room-temperature ionic conductivity of 2.7 × 10 −4 S cm −1 . Consequently, the corresponding solid-state lithium/LiFePO 4 battery exhibits a high capacity of ≈146 mAh g −1 with a high capacity retention of 94.3% for up to 300 cycles.

Cathode materials have impeded the development of aqueous Zn batteries (AZBs) for a long time due to their low capacity and poor cycling stability. Here, a “two birds with one stone” strategy is devised to optimize the Ni–Co hydroxide cathode material (NCH) for AZBs, which plays an essential role in both composition adjustment and morphology majorization. The F-doped Ni–Co hydroxide (FNCH) exhibits a unique nanoarray structure consisting of the 2D flake-like unit, furnishing abundant active sites for the redox reaction. A series of analyses prove that FNCH delivers improved electrical conductivity and enhanced electrochemical activity. Contributing to the unique morphology and adjusted characteristics, FNCH presents a higher discharge-specific capacity, more advantageous rate capability and competitive cycling stability than NCH. As a result, an aqueous Zn battery assembled with a FNCH cathode and Zn anode exhibits a high capacity of 0.23 mAh cm−2 at 1 mA cm−2, and retains 0.10 mAh cm−2 at 10 mA cm−2. More importantly, the FNCH–Zn battery demonstrates no capacity decay after 3000 cycles with a conspicuous capacity of 0.15 mAh cm−2 at 8 mA cm−2, indicating a superior cycling performance. This work provides a facile approach to develop high-performance cathodes for aqueous Zn batteries.

Solid-state lithium-metal batteries attract great attention due to their high energy density and superior safety. However, the sluggish Li + kinetics of solid electrolyte and poor interface compatibility between electrolyte and lithium anode lead to unsatisfied performance at room temperature, which severely limit their practical application. Herein, a Janus quasi-solid electrolyte (JSE) design is reported, which modifies the Li + solvation environment in succinonitrile (SN) plastic crystal electrolyte and creates 1D Li + transportation channels. Density functional theory calculations and Raman results reveal that Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 changes the Li + solvation environment from SN units to aggregated ion pairs, which accelerates the diffusion rate of Li + . As a result, JSE presents excellent ionic conductivity (0.73 mS cm −1 ) and high lithium transference number (0.72). With this efficient JSE, Li symmetric cells deliver excellent cycle stability over 600 h with a low over potential of 60 mV. LiFePO 4 |JSE|Li solid-state battery delivers an impressive performance with a specific discharge capacity of 152 mAh g −1 after 100 cycles at room temperature under 0.5 C. Moreover, the corresponding pouch cell also shows outstanding performance (140 mAh g −1 under 0.5 C) and withstands abuse tests such as bending and cutting, demonstrating its superior safety for future utilization.
