UT El Paso-led team designs cactus-inspired low-cost, efficient water-splitting catalyst

Green Car Congress

—Navid Attarzadeh Attarzadeh wondered what if they designed a 3D nickel-based catalyst in the shape of the prickly pear cactus? What caught my attention was how big the leaves and fruits were compared to other desert plants; the prickly pear has an extraordinary surface area. Resources Navid Attarzadeh, Debabrata Das, Srija N.

New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

The new battery design could help ease integration of renewable energy into the electrical grid at lower cost, using Earth-abundant metals, according to a study just published in Energy Storage Materials. Compared with a seasonal battery, this new design is especially adept at short- to medium-term grid energy storage over 12 to 24 hours.

UCLA team designs graphene-nanopocket-encaged PtCo nanocatalysts for fuel cells; highly durable, ultra-low loading

Green Car Congress

Researchers at UCLA, with colleagues at UC Irvine, have designed a graphene-nanopocket-encaged platinum cobalt (PtCo@Gnp) nanocatalyst for fuel cells with good electrochemical accessibility and exceptional durability under a demanding ultralow PGM loading (0.070 mg PGM cm –2 ) due to the non-contacting enclosure of graphene nanopockets.

IIT, Argonne team designs Li2O-based Li-air battery with solid electrolyte; four-electron reaction for higher energy density

Green Car Congress

In past lithium-air designs, the lithium in a lithium metal anode moves through a liquid electrolyte to combine with oxygen during the discharge, yielding lithium peroxide (Li 2 O 2 ) or superoxide (LiO 2 ) at the cathode. The capability to run with air avoids the need for oxygen tanks to operate, a problem with earlier designs.
