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.

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

Green Car Congress

As with the prior Lithium-Sulfur Battery Workshops in 2012 and 2013, this year’s symposium will bring together an international audience of scientists and industrial customers. Volkswagen AG filed a patent application in October 2012 (published in December 2013) on a new metal-sulfur battery system (e.g.,

CO2-neutral hydrogen storage with a bicarbonate/formate system

Green Car Congress

Bicarbonates are a component of many natural stones and are also commonly used as baking powder or sherbet (sodium bicarbonate, NaHCO 3 ). to sodium formate in 96% yield at 70 °C in water/THF without additional CO 2. Dehydrogenation of sodium formate was achieved with high conversion (> 90 %) under ambient temperature (30 °C).

Debunking the Lithium "Mining" FUD

Plug In India

Thier technical development unit has examined how the carbon footprint of electric cars in compares with that of internal combustion engines. 9,10,11,12] LFP (Lithium Iron Phosphate) and Sodium-Ion battery packs will not use Cobalt and Nickel. With a clear result. And the clear result is EV’s are way better [7].
