Ironically, one of the lesser-known heavyweights making rounds in the emerging energy scene isn’t a heavyweight at all. Iron, typically associated with strength and sturdiness, is now flexing its muscles in a field where finesse and adaptability are paramount—energy storage. The star of the show is a new metal-organic complex known as iron (Fe)-NTMPA2, a potential game-changer in the quest for efficient storage solutions. In aqueous iron redox flow batteries, it’s breaking the mold with a set of impressive statistics: a whopping 96% capacity utilization, minimal capacity fade, and near-perfect efficiency scores, all secured over an arduous journey of 1,000 charge/discharge cycles. Add in the theoretical potential for up to 9 Wh/L in energy density, and it’s clear why eyebrows are raising in the scientific community.
