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.

Penn State team proposes cold sintering as way to improve solid-state battery production

Green Car Congress

Penn State researchers have proposed cold sintering as an improved method of solid-state battery production that enables multi-material integration for better batteries. This prevents fire-causing short circuits, but also in theory it enables solid-state batteries to have higher energy density. —Zane Grady, lead author.

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. There are, researchers have discovered, a wide range of options to harvest enough microwatts to replace wearables’ batteries. 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.
