Iron-air batteries (1,200 Wh/kg), and in general metal-air [1], might bring a surprise after 2024: December 2022, "Form Energy will site first American iron-air battery manufacturing plant in Weirton, West Virginia" [2].

- londons_explore 4y agoThe various "-air" batteries tend to have major downsides... They tend to get heavier as they discharge. They usually aren't rechargeable (or if they are, only a few times or with much lower energy densities). They tend to self-discharge within a few weeks of non-use.
- ly3xqhl8g9 4y agoYes, there are downsides, as always in engineering, it's a matter of managing the compromises for the current implementation and researching better solutions for the next iteration.
