Argonne-led team develops new low-cost cobalt-based catalyst for PEM electrolysis

Green Car Congress

A multi-institutional team led by the US Department of Energy’s (DOE) Argonne National Laboratory (ANL) has developed a low-cost cobalt-based catalyst for the production of hydrogen in a proton exchange membrane water electrolyzer (PEMWE). volts (Nafion 212 membrane) and low degradation in an accelerated stress test.

UCLA team uses graphite to boost performance of lithium iron phosphate cathode materials

Green Car Congress

Lithium iron phosphate (LiFePO 4 ) is widely used as a low-cost, safer cathode material for Li-ion batteries; however, low ionic and electronic conductivity limit its rate performance. C), ultrahigh rate capability (107 mAh g –1 under 60 C), and outstanding cycle performance (>95% reversible capacity retention over 2000 cycles).

BIT, FAW team develops turbocharged, DI hydrogen engine; high power and efficiency, near-zero NOx

Green Car Congress

Peak power of 120 kW @ 4400 rpm and a maximum torque of 340 N·m @ 2000 rpm can be achieved with the matched turbocharger. The direct-injection (DI) hydrogen engine can offer large power with low cost and rely less on hydrogen purity. of 1.91 @ 2000 rpm and 40.4% A paper on the study appears in the journal Fuel.

Silica-based cathode enables long-life Li-S batteries

Green Car Congress

Lithium–sulfur batteries—composed of a sulfur-based cathode and lithium anode submerged in a liquid electrolyte—are promising candidates to replace the ubiquitous lithium-ion battery because of their low cost and the non-toxicity and abundance of sulfur. Silica, a low-cost metal oxide, is actually non-conducting.
