New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

Researchers led by the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have extended the capacity and duration of sodium-aluminum batteries. The new sodium-based molten salt battery uses two distinct reactions. It is a variation of a sodium-metal halide battery. of peak charge capacity.

Hatch report finds NOVONIX dry cathode synthesis process offers cost and waste reduction improvements

Green Car Congress

Hatch was commissioned to conduct a commercial-scale capital and operating cost comparison study, as well as a high-level evaluation of plant emissions and impacts to natural resources between NOVONIX’s patent-pending process and the conventional wet process.

Researchers improve the performance of sodium-ion batteries by using tailored carbon anodes with hierarchical porosity

Green Car Congress

Researchers at Justus Liebig University, Giessen, Germany, have improved the performance of sodium-ion batteries ( earlier post ) by using tailor-made carbon materials with hierarchical porosity for the anode instead of common carbon-based anode materials. 1 at C/5 while exhibiting excellent rate capability and reasonable cycle life.

Fraunhofer holding 3rd annual workshop on Li-sulfur batteries in November

Green Car Congress

Oliver Gröger from Volkswagen AG on recent developments on Li-sulfur batteries with silicon anodes and a comparison to commercially available NMC-based batteries. Volkswagen AG filed a patent application in October 2012 (published in December 2013) on a new metal-sulfur battery system (e.g.,

Antimony nanocrystals as high-capacity anode materials for both Li-ion and Na-ion batteries

Green Car Congress

The data for 10 nm Sn (tin) NCs are shown for comparison. Initial studies revealed that antimony could be suitable for both rechargeable lithium- and sodium-ion batteries because it is able to store both kinds of ions. 20C (1C = 0.66 1 , 9 cycles at each C-rate, first cycle at 0.1C).

Tsinghua researchers conclude surging lithium price will not impede EV boom

Green Car Congress

The collective impact prompted an increase in LIB price in the second half of 2021, reversing its 30-year decline that began with the first-ever commercial product in 1991. In comparison, only 40% of global oil supply clusters in the top 3 producing countries. That made the cathode price increase by 140% for LiNi 0.8

OSU team demonstrates concept of potassium-air battery as alternative to lithium-air systems

Green Car Congress

contrast with LiO 2 and NaO 2 , KO 2 is thermodynamically stable and commercially available. Potassium, an alkali metal similar to lithium (and sodium) can be used in a rechargeable battery. For comparison, they built a Li?O mA/cm 2 —the lowest ever reported in metal-oxygen batteries, according to the team. O 2 batteries.In
