Despite being one of the most promising candidates for grid-level energy storage, practical aqueous zinc batteries are limited by dendrite formation, which leads to significantly compromised safety and cycling performance. In this study, using single-crystal Zn-metal anodes, reversible electrodeposition planar Zn with a high capacity 8 mAh cm-2 can be achieved at an unprecedentedly current density 200 mA . This dendrite-free electrode is well maintained even after prolonged (>1200 cycles 50...

An advantageous solid electrolyte/liquid electrolyte interface is crucial for the implementation of a protected lithium anode in liquid cells. Li6.5La3Zr1.5Ta0.5O12 (LLZTO) garnet electrolytes are among few that stable contact with metal. We show LLZTO unstable organic carbonate-based Li+ used conventional Li-ion The interfacial resistance between and LiPF6 (CH2O)2CO: OC(OCH3)2 (1:1 v/v) increases time due to growth lithium-ion-conducting interphase (SEI) at surface ceramic electrolyte....

Abstract The solid electrolyte interphase (SEI), a complex layer that forms over the surface of electrodes exposed to battery electrolyte, has central influence on structural evolution electrode during operation. For lithium metallic anodes, tailoring this SEI is regarded as one most effective avenues for ensuring consistent cycling behavior, and thus practical efficiencies. While fluoride‐rich interphases in particular seem beneficial, how they alter dynamics plating stripping promote...
Aqueous zinc electrolytes offer the potential for cheaper rechargeable batteries due to their safe compatibility with high capacity metal anode; yet, they are stymied by irregular deposition and consequent dendrite growth. Suppressing formation tailoring electrolyte is a proven approach from lithium batteries; underlying mechanistic understanding that guides such does not necessarily directly translate one system other. Here, it shown electrostatic shielding mechanism, fundamental concept in...

Lithium metal batteries with liquid electrolytes usually suffer from the growth of lithium dendrites and safety issues such as leaking volatilization. Solid polymer (SPEs) can relieve these problems due to their chemical electrochemistry stability. However, PEO-based SPEs are still too brittle endure bending, stretching, shearing. Herein, highly elastic cyclodextrin-based triblock (CDTPEs) were fabricated via ring-opening polymerization initiator-free thiol–ene reaction. The rubbery PTMC...
