Significance Solid-state lithium metal anode possesses great promise owing to its high energy density and improved safety. This work introduces a strategy for constructing 3D Li anode, which is hosted in solid-state ion-conducting host shows safe dendrite-free plating/stripping behavior. The based on garnet-type ion-conductive framework bottom-deposited Cu current collector. plated within the solid garnet from bottom layer deposition behavior, effectively averting dendrite penetration issue....

The 3D carbon matrix obtained from the carbonized activated wood (denoted as CA‐wood) serves superconductive current collector an ideal host accommodating catalysts. ruthenium (Ru) nanoparticles are uniformly anchored on wall of aligned microchannels CA‐wood/Ru). open inside contribute to unimpeded oxygen gas diffusion. Moreover, hierarchical pores...
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.

This dendrite-free electrode is well maintained even after prolonged (>1200 cycles 50...

Many studies of solid-state battery cathodes employ high stack pressures and low current densities. In practice, cells operating at densities in the mA cm−2 range a few MPa are required. Here, we show influence composite cathode components LiNi0.83Mn0.06Co0.11O2, Li3InCl6, carbon nanofibers, 2-MPa pressure find that overall capacity is determined primarily by conductivity solid electrolyte. Higher conductivities reduce mass electrolyte required to access from active material (high...
Abstract Li‐CO 2 batteries have emerged as a promising energy storage technology due to their high theoretical density. A thick electrode design is an effective approach for further increasing the density on device level by decreasing weight and volume ratios of inactive materials. Exploring designing novel electrodes with catalytic activity toward reversible reaction between lithium carbon dioxide are key challenges achieve low charge overpotential, long cycling stability, rate performance....
High-temperature batteries require the battery components to be thermally stable and function properly at high temperatures. Conventional have high-temperature safety issues such as thermal runaway, which are mainly attributed properties of liquid organic electrolytes low boiling points flammability.

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...
Void formation at the Li/ceramic electrolyte interface of an all-solid-state battery on discharge results in high local current densities, dendrites charge, and cell failure.

Polymers designed with a specific combination of electrochemical, mechanical, and chemical properties could help overcome challenges limiting practical all-solid-state batteries for high-performance next-generation energy storage devices. In composite cathodes, comprising active cathode material, inorganic solid electrolyte, carbon, battery longevity is limited by particle volume changes occurring on charge/discharge. To this, impractical high pressures are applied to maintain interfacial...
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.
