And this is just autos. At the COP26 climate summit in Glasgow, Prime Minister Narendra Modi’s government vowed to meet 50% of the country’s energy needs from non-fossil-fuel sources by 2030. To reach that goal, wind and solar power will also require storage. What’s more, those batteries will need to be carried to remote places. Unlike lithium-ion, which is a known fire hazard, sodium-ion cells can be discharged to zero volts — making them less likely to explode in transit. Faradion’s patent for this may give Reliance an advantage. Another of the Indian conglomerate’s recent battery deals, a $50 million investment in Marlborough, Massachusetts-based Ambri Inc., may have a similar aim of developing expertise for safe, economical storage of large-scale renewable power by using calcium and antimony electrodes.
