The Stable 3D Zn Electrode for High-Power Density Zn Metal Batteries
نویسندگان
چکیده
A stable Zn metal electrode can develop rechargeable zinc batteries (RZMBs) which have the high theoretical capacity (820 mAh g ?1 ), low redox potential, and intrinsic safety. However, corrosion of in aqueous electrolytes dendrite formation during plating process lead to poor cycling thus hinder development RZMBs. Here, we employed ionic liquid-based gel polymer (poly(vinylidene fluoride)-co-hexafluoropropylene, PVDF-HFP) acetylene black (AB) achieve a flexible three-dimensional (3D) Zn/AB/PVDF-HFP film with electronic conductive networks surface area, showing 26 times higher plating/stripping current than planar plate. By developing continuous structure between membrane 3D electrode, resistance, rate capability long cycle life (> 800 h) was obtained. Our work shows electrolyte, could pave path for high-cycle thin-film

Report: Photoelectrochemically Rechargeable Zn-Air Batteries
This work aims to design photoelectrochemically rechargeable Zn-air batteries with improved energy and power density, energy efficiency and cycle life. Our plan is to solve the bottle-neck problem associated with air electrocatalysts by developing novel nanocarbon-inorganic hybrid materials for oxygen reduction and/or evolution with high efficiency and durability. Also, we are pursuing active a...
متن کاملSOME Zn−1 TERRACES FROM Zn POWER-SEQUENCES, n BEING AN ODD PRIME POWER
A terrace for Zm is a particular type of sequence formed from the m elements of Zm. For m odd, many procedures are available for constructing power-sequence terraces for Zm; each terrace of this sort may be partitioned into segments, of which one contains merely the zero element of Zm, whereas every other segment is either a sequence of successive powers of an element of Zm or such a sequence m...
متن کاملPartially crystalline Zn₂GeO₄ nanorod/graphene composites as anode materials for high performance lithium ion batteries.
Zn2GeO4 nanorod/graphene composites (ZGCs) were yielded by a two-step hydrothermal processing. Crystalline and amorphous regions were found to coexist in a single Zn2GeO4 nanorod. The surface of the Zn2GeO4 nanorod was compactly covered and anchored by graphene sheets. The ZGCs were then utilized as anodes for lithium ion batteries (LIBs). Intriguingly, partially crystalline ZGC containing 10.2...
متن کاملLow-Temperature Carbon Coating of Nanosized Li1.015Al0.06Mn1.925O4 and High-Density Electrode for High-Power Li-Ion Batteries.
Despite their good intrinsic rate capability, nanosized spinel cathode materials cannot fulfill the requirement of high electrode density and volumetric energy density. Standard carbon coating cannot be applied on spinel materials due to the formation of oxygen defects during the high-temperature annealing process. To overcome these problems, here we present a composite material consisting of a...
متن کاملDoped LiFePO4 Cathodes for High Power Density Lithium Ion Batteries
Olivine LiFePO4 has received much attention recently as a promising storage compound for cathodes in lithium ion batteries. It has an energy density similar to that of LiCoO 2, the current industry standard for cathode materials in lithium ion batteries, but with a lower raw materials cost and an increased level of safety. An inherent limitation of LiFePO4 acknowledged by researchers studying t...
