Why This Mars Battery Could Beat Lithium-Ion

Most lithium-ion batteries tap out after a few hours. Take your personal data back with Incogni! Use code UNDECIDED at the link below and get 60% off an annual plan: http://incogni.com/undecided. 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?

Corrections (clarifications):
Lot of confusion in the comments about how this actually works, so here's the short version. Think photosynthesis, not battery-in-a-tank.

Noon's system pulls CO2 from the air and splits it into solid carbon and oxygen using electricity. The oxygen vents back to the atmosphere; the carbon is what stores the energy ... it's the fuel sitting in the tank. To discharge, the carbon is reoxidized inside a solid oxide fuel cell, recombining with oxygen back into CO2 and releasing electricity as it goes. No net carbon released over a full cycle.

The Mars connection isn't a metaphor: Chris Graves, Noon's co-founder, helped build NASA's MOXIE. The box on Perseverance that made oxygen on Mars by splitting CO2. Same core chemistry, different job.
