The quest for advanced energy storage devices with cheaper, safer, more resource-abundant has triggered intense research into zinc ion batteries (ZIBs). Among them, organic materials as cathode ZIBs have attracted great interest due to their flexible structure designability, high theoretical capacity, environmental friendliness, and sustainability. Although numerous electrode been studied diffe...

The development of rechargeable batteries based on a Ca metal anode demands the identification suitable cathode materials. This work investigates potential application variety compounds, which are selected from inorganic crystal structural database, considering 3d-transition oxysulfides, pyrophosphates, silicates, nitrides, and phosphates with maximum four different chemical elements in their c...

Unveiling the thermodynamic and kinetic properties of Na x Fe(SO 4) 2 (x = 0–2): toward a high-capacity and low-cost cathode material New kinds of eldfellite materials are discovered to obtain higher capacity by ab initio quantum mechanical calculations. Moreover, the phase stability, electrochemical properties and ionic diff usion are also investigated to unveil the thermodynamic and kinetic p...

A new and simplified approach for making cathodes for microbial fuel cells (MFCs) was developed by using metal mesh current collectors and inexpensive polymer/carbon diffusion layers (DLs). Rather than adding a current collector to a cathode material such as carbon cloth, we constructed the cathode around the metal mesh itself, thereby avoiding the need for the carbon cloth or other supporting ...

Since the introduction to market by Sony in the early 1990s,[1] lithium-ion batteries (LIBs) have become dominate power sources for consumer electronics and have been recognized as a critical enabling technology to make electric vehicles (EVs)/ hybrid electric vehicles (HEVs) a success.[2] They are also being used to store carbon-free and renewable energy sources, such as solar, wind, and ocean...

a r t i c l e i n f o High-performance microbial fuel cell (MFC) air cathodes were constructed using a combination of inexpensive materials for the oxygen reduction cathode catalyst and the electrode separator. A poly(vinyl alcohol) (PVA)-based electrode separator enabled high coulombic efficiencies (CEs) in MFCs with activated carbon (AC) cathodes without significantly decreasing power output....

The slow activity of cathode materials is one of the most significant barriers to realizing the operation of solid oxide fuel cells below 500 °C. Here we report a niobium and tantalum co-substituted perovskite SrCo0.8Nb0.1Ta0.1O3-δ as a cathode, which exhibits high electroactivity. This cathode has an area-specific polarization resistance as low as ∼0.16 and ∼0.68 Ω cm2 in a symmetrical cell an...

Methane-producing bioelectrochemical systems (BESs) are a promising technology to convert renewable surplus electricity into the form of storable methane. One of the key challenges for this technology is the search for suitable cathode materials with improved biocompatibility and low cost. Here, we study heat-treated stainless steel felt (HSSF) for its performance as biocathode. The HSSF had su...
