Summary:
Sodium metal halide batteries were developed first in the 1980s-90s for electric vehicles, for which the critical metric to achieve was power density. This application focus caused the sodium nickel chloride chemistry to be used along with high power, higher cost cell designs. With the coming need for long duration energy storage on the grid--for which low-cost, not high power density, is the goal--there is an opportunity to re-optimize the proven sodium metal halide battery technology. In particular, the ultra-low cost active materials in the sodium iron chloride chemistry are attractive for economic bulk power storage. In this presentation, Inlyte will share the latest advances and testing results on its proprietary iron cathode chemistry, as well as its next generation sodium iron chloride cells, modules, and integrated systems that have been redesigned for low cost, deployability, and reliability. The technoeconomics of Inlyte’s technology will be discussed, along with its unique advantages across daily cycling and energy resilience applications and Inlyte’s progress towards commercialization at scale.
