Better and more cost-efficient production methods for energy storage are increasingly in demand, especially in Germany: All major automobile manufacturers have launched ambitious electric vehicle programs that will ensure a sharp rise in demand for batteries. BroadBit uses it to produce new types of sodium-ion batteries.

Researchers at Chalmers University of Technology, Sweden, have developed a nanometric graphite-like anode for sodium ion (Na + storage), formed by stacked graphene sheets functionalized only on one side, termed Janus graphene. The estimated sodium storage up to C 6.9 Na is comparable to graphite for standard lithium ion batteries.

F 0.7 , for sodium-ion (Na-ion) batteries (NIBs). While high-energy Li-ion batteries (LIBs) are expected to contribute in part to the solution, the high cost and low stability prohibit wide application in this area, the researchers observe. by tailoring the polyanion group of the crystal and expanding the redox range to V3.8+/V5+

Stationary energy storage systems that can operate for many cycles, at high power, with high round-trip energy efficiency, and at low cost are required. Cost is a greater concern. We decided we needed to develop a new chemistry if we were going to make low-cost batteries and battery electrodes for the power grid.

Although some sulfur-containing polymers with short -S 2-4 - chains can avoid “polysulphide-shuttling”, the low sulfur content still limits the performance of Li-S cathodes. The reactions of organohalides with sodium polysulfide and sulfur with dithiols seem to be the most effective routes to obtain organosulfur polymers. Chen et al.

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.

In their paper on the work published in the journal Joule , the researchers reported that by using a reduced graphene oxide (rGO)/sodium lignosulfonate (SL) composite on the standard polypropylene (PP) separator (rGO@SL/PP), they demonstrated a highly robust Li-S battery with a capacity retention of 74% over 1,000 cycles. … —Lei et al.
