I think this was just poor wording in the article. My local power company (Dominion Energy VA) recently started a huge iron-air battery project because the technology supports 100 hours of active discharge [0]. I'm sure there's some background discharge, but it takes a lot longer than 100 hours for iron to naturally rust through. [0]: https://www.pbs.org/wgbh/nova/article/iron-air-battery-renew... |
