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.

Researchers develop rechargeable hybrid-seawater fuel cell; highly energy density, stable cycling

Green Car Congress

The circulating seawater in the open-cathode system results in a continuous supply of sodium ions, endowing the system with superior cycling stability that allows the application of various alternative anodes to sodium metal by compensating for irreversible charge losses. an alloying material), in full sodium-ion configuration.

Mangrove raises $3M from BDC Capital to accelerate deployment of battery-grade lithium processing systems

Green Car Congress

Mangrove’s modular solution can be scaled to any capacity and co-located with upstream lithium producers or cathode and cell manufacturers. The platform technology is also being commercialized for conversion of waste brines to chemicals and desalinated water. The process creates an effluent stream with salinity below 3,000 ppm.

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. The standard method for manufacturing porous silicon is a subtraction method, similar to making a sculpture. They then treat the material with a sodium potassium alloy.

Researchers Develop New Lower-Cost, Efficient Catalyst for Water Gas Shift Reaction for Hydrogen Production

Green Car Congress

A team of researchers from Tufts University, the University of Wisconsin-Madison and Harvard University report that alkali ions (sodium or potassium) added in small amounts activate platinum adsorbed on alumina or silica for the low-temperature water-gas shift (WGS) reaction (H 2 O+CO→ H 2 +CO 2 ) used for producing hydrogen.

New oxygenate additive for diesel fuels from glycerol

Green Car Congress

Researchers from Tatung and National Cheng Kung Universities in China, and Case Western Reserve University in Ohio, report manufacturing a new oxygenate additive for diesels (bio or petroleum) using glycerol (a major byproduct of biodiesel production), dimethyl sulfate (DMS), and sodium hydroxide pellets as raw materials.
