One key area of interest is sodium, the earth-abundant ingredient that makes up about 40% of simple table salt. Sodium is heavy, though. So is salt, for that matter. Nevertheless, sodium batteries are relatively inexpensive and free from thorny supply chain issues, and they are beginning to bust into the mainstream market.
However, the second generation sodium ion could reach $40 per kWh. Iron LFP batteries could get to $50/kWh with really high volume and efficiency at the cell level. The future low price of sodium ion would make for insanely cheap fixed storage products like the Tesla Megapack and Powerwalls. They also do not have practical material limits.
At the sodium-ion battery forum, Chen Liquan, an academician of the Chinese Academy of Engineering, said that with the improvement of the industry chain, technology maturity, and scale effect, the cost of sodium-ion batteries is expected to be more than 20 percent lower than LFP batteries.
Lower-cost sodium-ion batteries are finally having their moment « Adafruit Industries – Makers, hackers, artists, designers and engineers! Illustration of the various electrode structures in sodium-ion batteries from Chemical Society Reviews via Wikipedia As the world moves toward heavier reliance on stored energy, we need better batteries.
Meanwhile, Argonne notes that stationary energy storage is another ripe market for sodium-ion batteries. Sure enough, over at the Pacific Northwest National Laboratory another kind of sodium battery is taking shape, which deploys a combination of aluminum and sodium in the form of a molten salt.
As the demand for sodium-ion batteries increases, similar efforts will be made to establish equipment manufacturing for sodium-ion cells in India. By around 2025, it is anticipated that the installation of equipment for sodium-ion batteries will be in progress, enabling the stepwise growth of the market share for sodium-ion technology in India.
