New hierarchical metal-organic nanocomposite cathode for high-energy sodium-ion batteries

Green Car Congress

Building on earlier work, researchers in China have fabricated a hierarchical metal-organic nanocomposite for use as a cathode in sodium-ion batteries (SIBs). Moreover, the transition metal ions participate in the electrochemical reaction at high potentials that is helpful to raise the battery voltage. —Huang et al.

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

And today, technology is maturing to the point that meaningful amounts of these energy giveaways can be harvested to liberate wearables from ever needing a battery. Energy is something we take for granted, because we just plug things into the wall, and it feels as inevitable as air. Batteries die before animals do.

BASF investigating sodium-air batteries as alternative to Li-air; patent application filed with USPTO

Green Car Congress

In a paper in Nature Materials , a team of researchers from BASF SE and Justus-Liebig-Universität Gießen report on the performance of a sodium-air (sodium superoxide) cell. Their work, they suggest, demonstrates that substitution of lithium by sodium may offer an unexpected route towards rechargeable metal–air batteries.
