New liquid alloy electrode significantly lowers operating temperature of sodium-beta batteries; improved performance

Green Car Congress

Researchers at Pacific Northwest National Laboratory (PNNL) have devised an alloying strategy that enables sodium-beta batteries to operate at significantly lower temperatures. The new electrode enables sodium-beta batteries to last longer, helps streamline their manufacturing process and reduces the risk of accidental fire.

New mesoporous crystalline Si exhibits increased rate of H2 production; potential use in Li-ion batteries also

Green Car Congress

The nanosized crystalline primary particles and high surface areas enable an increased rate of photocatalytic hydrogen production from water and extended working life. Instead, Wang’s team uses a chemically based method that builds up the material rather than removing it. They then treat the material with a sodium potassium alloy.

Caltech engineers devise new thermochemical cycle for water splitting for H2; recyclable, non-toxic, non-corrosive and at lower temperatures

Green Car Congress

The thermochemical production of hydrogen and oxygen from water via a series of chemical reactions is of interest because it directly converts thermal energy into stored chemical energy (hydrogen and oxygen), and thus can take advantage of excess heat given off by other processes. —Xu et al.

Researchers convert atmospheric CO2 to carbon nanofibers and nanotubes for use as anodes in Li-ion and Na-ion batteries

Green Car Congress

Researchers from George Washington University and Vanderbilt University have demonstrated the conversion of atmospheric CO 2 into carbon nanofibers (CNFs) and carbon nanotubes (CNTs) for use as high-performance anodes in both lithium-ion and sodium-ion batteries. times above that of sodium-ion batteries with graphite electrodes.

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

The best-known wearable energy-harvesting tech today is, of course, solar, which pulls down electrons from sunlight or ambient light. But solar is just the opening gambit. A backpack with a giant solar panel might work technically, but not in reality. volts for about 60 hours. Leveraging watch tech for…bisons?
