May 26, 2026 - Why This Mars Battery Could Beat Lithium-Ion
Most lithium-ion batteries tap out after a few hours. This one just hit 100. And the tech behind it didn`t start in a battery lab … it started on Mars, with a NASA experiment designed to split CO2 into carbon and oxygen. Here`s how the system works and how it stacks up against lithium-ion for grid-scale energy storage. Could a battery born on Mars actually beat lithium-ion at grid-scale energy storage?
