Borated graphite cathodes for low-temperature aluminum electrolysis

High Capacity, Temperature-Stable Lithium Aluminum Manganese Oxide Cathodes for Rechargeable Batteries

Manganese oxides are of great interest as low cost and environmentally sound intercalation cathodes for rechargeable lithium batteries, but have suffered from limited capacity and instability upon cycling at the moderately high temperatures (50-70°C) encountered in many applications. Here, we show that LixAl0.05Mn0.95O2 of both the monoclinic and orthorhombic ordered rock salt structures exhibi...

Burnishing of Aluminum-Magnesium-Graphite Composites

Low temperature preparation of crystalline ZrO2 coatings for improved elevated-temperature performances of Li-ion battery cathodes.

Ultrathin crystalline ZrO(2) nanofilms have been facilely deposited on LiMn(2)O(4) particles at 120 °C using atomic layer deposition. The ZrO(2) coating shows high crystallinity, conformality and homogeneity, which contribute to considerably improved electrochemical performance of LiMn(2)O(4) at elevated temperature in lithium-ion batteries.

Cast Aluminum Alloy for High Temperature Applications

Originally developed by NASA as high performance piston alloys to meet U.S. automotive legislation requiring low exhaust emission, the novel NASA alloys now offer dramatic increase in tensile strength for many other applications at elevated temperatures from 450°F (232°C) to about 750°F (400°C). It is an ideal low cost material for cast automotive components such as pistons, cylinder heads, cyl...

The use and optimization of stainless steel mesh cathodes in microbial electrolysis cells

Microbial electrolysis cells (MECs) provide a high-yield method for producing hydrogen from renewable biomass. One challenge for commercialization of the technology is a lowcost and highly efficient cathode. Stainless steel (SS) is very inexpensive, and cathodes made of this material with high specific surface areas can achieve performance similar to carbon cathodes containing a platinum cataly...
