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). 2017) “In-Situ Formed Hierarchical Metal-Organic Flexible Cathode for High-Energy Sodium-Ion Batteries” ChemSusChem doi: 10.1002/cssc.201701484. and Huang, Y. 201701484.

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.

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

Green Car Congress

Current battery electrodes are a mixture of active material, carbon, and the liquid electrolyte. The best way to give ions a path is by introducing a solid electrolyte, which requires sintering, and conventional sintering is too hot for carbon and active material, causing them to degrade. Sintered triphasic cathode.

DOE to award up to $12M for applied RD in hydrogen storage technologies

Green Car Congress

350 to 700 bar) storage vessels are constructed using expensive high-strength carbon fiber, such as Toray T700S, in a composite matrix as an overwrap to contain the stress. An example of a possible solution is using fibers with mechanical strengths matching or exceeding the properties of aerospace quality carbon fiber (e.g.

NETL investigating researching chemistries for large-scale battery- and supercapacitor-based grid energy storage systems

Green Car Congress

This includes research on appropriate anodes, cathodes, and electrolytes for magnesium (Mg)-, sodium (Na)-, and lithium (Li)-based batteries and novel transition metal oxide- and nitride-based supercapacitor electrode materials. Sodium is another element that is less expensive than lithium. Novel cathodes and anodes.
