Cornell study examines trade-off between critical metals requirement and transportation decarbonization

Green Car Congress

Countries should adopt policies that prioritize alternative designs for cathodes/anodes and fuel-cell (green hydrogen) systems to reduce the reliance on primary critical metals. Zhang et al. Monotonic growth in global demand for critical metals to 2050 is the most prevalent trend.

New superionic conductor could result in highest energy density solid-state batteries to date

Green Car Congress

Scientists from Tohoku University and the High Energy Accelerator Research Organization have developed a new complex hydride lithium superionic conductor that could result in all-solid-state batteries with the highest energy density to date. High-energy-density all-solid-state lithium metal battery employing complex hydrides.

3 winners of DOE’s “America’s Next Top Energy Innovator” Challenge: hydrogen-assisted lean-burn engines, graphene for Li-air and -sulfur batteries, and titanium process

Green Car Congress

Umpqua Energy’s EVOPAC system combines an advanced hydrogen-injection system using a plasma reformer with a DeNOx Catalyst. The plasma reformer, installed into the engine compartment, convert fuel into hydrogen. The hydrogen causes the fuel to burn more completely, resulting in greater fuel efficiency, less emissions, and more power.

Technical review outlines challenges for both batteries and fuel cells as basis for electric vehicles

Green Car Congress

Hydrogen produced via electrolysis using the EU mix or by natural gas reforming would exceed the target.). This will be followed by an assessment of the perceived technological barriers and the potential energy density gains for so-called post-LiBs, namely lithium-oxygen and lithium-sulfur batteries.

Researchers develop an air-stable and waterproof lithium metal anode using wax

Green Car Congress

Lithium metal is highly sensitive to moisture and oxidative components in the air, leading to the generation of insulating products such as lithium hydroxides on its surface and the resultant deterioration of the electrochemical performance. There was no combustion or capacity decay even after direct contact with water.

Because pinholes in the surface protection layer would undermine the uniformity of ion flux, the researchers proposed a unique double-layer structure to enhance the defect tolerance of the design. V versus standard hydrogen electrodes). I.e., defects in one layer can be screened by the other intact layer. 1 ) and lowest potential (?3.040?V
