For over a decade, China’s $300 billion battery industry has dominated the global energy future through lithium. But what if a small U.S. startup just broke that stranglehold? Meet Peak Energy, the Colorado-based company that secretly developed and deployed the world’s largest sodium-ion battery — no lithium, no cobalt, no rare earth metals. This new sodium-iron phosphate pyrophosphate (NFPP) battery promises to be safer, cheaper, and made from abundant materials like iron, carbon, and salt. It can’t catch fire, works in sub-zero temperatures, and survives full discharge cycles without damage.
