Sulfur nanodots on nickel foam as high-performance Li-S cathode materials; carbon- and binder-free

Green Car Congress

A team at Nankai University in China has devised high-performance Li-sulfur battery cathode materials consisting of sulfur nanodots (2 nm average) directly electrodeposited on flexible nickel foam; the cathode materials incorporate no carbon or binder. mg/cm 2 S on the Ni foam exhibited high initial discharge capacity (1458 mAh/g at 0.1

GWU team demonstrates relatively efficient electrochemical process for low-GHG production of ammonia

Green Car Congress

V under 2 milliamperes per centimeter squared (mA cm -2 ) of applied current at coulombic efficiency of 35% (35% of the applied current results in the six-electron conversion of N 2 and water to ammonia, and excess H 2 is cogenerated with the ammonia). At 200 C in an electrolyte with a molar ratio of 0.5 KOH, ammonia is produced at 1.2

GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

Green Car Congress

Until recently, CNTs had not been produced at low energies, nor had they been produced in high yield from CO 2. The electrolysis occurs at low electrical energy and high coulombic efficiency ($4 Faraday per mole CO 2 ). Click to enlarge. The process uses electrolysis to split CO 2 dissolved in a molten carbonate.

SciAps introducing family of handheld analyzers for in-field analysis of lithium and rare earth elements

Green Car Congress

A detector measures the energy and intensity (number of x-rays per second at a specific energy) of each X-ray, which is transformed into an elemental concentration using either a non-standard technique such as fundamental parameters or user-generated calibration curves. SciAps recognizes that no single tool solves every problem.

Researchers develop non-flammable fluorinated electrolyte for Li-metal anodes with aggressive cathode chemistries; toward a 500 Wh/kg goal

Green Car Congress

Researchers at the University of Maryland (UMD), the US Army Research Laboratory (ARL), and Argonne National Laboratory (ANL) have developed a non-flammable fluorinated electrolyte that supports the most aggressive and high-voltage cathodes in a Li-metal battery. Li metal offers one of the highest specific capacities (3,860 mAh g ?1
