A sulfur/carbon composite material was prepared by heat treatment of doped mesoporous carbon and elemental sulfur at a temperature inside a stainless steel vessel, which was used as a cathode in lithium/sulfur batteries that were tested in ionic-liquid electrolytes.
The use of highly toxic and flammable solvents in the manufacturing of batteries with voltages of higher than 1.3V for applications such as electric drive vehicles and stationary electrochemical energy storage are driving processing approaches to less toxic, aqueous techniques
Connectors are key components of electrical power transmission systems. The widely used compression splice connectors were originally designed for low temperature applications, normally less than 70°C.
Here, we discuss how CSES is used to rank candidate threats (i.e., semantically enhanced structural anomalies) for the benefit of a human operator assessment: (a) regarding their potential as a significant emergent threat and its consequent impacts, (b) semantics will be used
Mesoporous carbon materials lack sufficient ordering at the atomic scale to exhibit good conductivity properties and good thermal stability.
Successful, economically feasible thermomechanical processing of rare earth free magnesium alloys has been accomplished by a novel rolling method.
This invention merges fluid power with emerging additive manufacturing techniques. Additive manufacturing produces components layer by layer and is known to create complex articles.
The extreme sensitivity of SERS is dominated by the electromagnetic enhancement, referring to the intense, spatially varying E fields produced by plasmonic coupling between closely spaced metal nanoparticles.
The drive system includes electric machine and inverter. The cost of a drive system for vehicles is currently too high. It is over four times the DOE 2020 cost target. Permanent magnet (PM) is a major cost item in an interior PM machine.
The present invention relates to improved energy density for rechargeable Li-ion batteries. Such improvements require use of high-capacity and high-voltage cathode materials, but charging to voltages approaching 4.5-5V invariably causes rapid loss of capacity with cycling.
