Sodium-ion Batteries

Hi everyone,

The wikipedia page on Na-ion Batteries has been thoroughly updated and revised and now represents a really good introduction to the current status of this important, new energy storage technology:

https://en.wikipedia.org/wiki/Sodium-ion_battery

The history of the technology is covered plus the background status from active materials through to current-day commercialization. A good summary of all the companies currently active in this space is given, including Faradion:

Faradion Limited: Founded in 2011 in the United Kingdom, their chief cell design uses oxide cathodes with hard carbon anode and a liquid electrolyte. Their pouch cells have energy densities comparable to commercial Li-ion batteries (140 – 150 Wh/kg at cell-level) with good rate performance till 3C and cycle lives of 300 (100% depth of discharge) to over 1,000 cycles (80% depth of discharge).The viability of its scaled-up battery packs for e-bike and e-scooter applications has been shown.They have also demonstrated transporting sodium-ion cells in the shorted state (at 0 V), effectively eliminating any risks from commercial transport of such cells. The company's CTO is Dr. Jerry Barker, co-inventor of several popularly used lithium-ion and sodium-ion electrode materials such as LiM1M2PO4, Li3M2(PO4)3, and Na3M2(PO4)2F3 and the carbothermal reduction method of synthesis for battery electrode materials.

The future of energy storage is Sodium-ion!
