Aquion - Metal-Hydrogen Battery
While metal-hydrogen batteries are not commercially available yet, get to know how they work and why NASA uses them. Metal-hydrogen, especially nickel-hydrogen, batteries are already in use in space. They’re used on the International Space Station (ISS). These are flexible batteries designed for short- to long-term use, with nickel and pressurized hydrogen as the primary elements included.
When Can We Expect It?
Likely, we won’t see metal hydrogen batteries commercialized for a few years, but there are bids from current manufacturers to start the process. It might take a while for those bids to go through and more time to design manufacturing facilities and produce purpose-built batteries. Despite that, these batteries are considered a good prospect for renewable energy storage from wind and solar.
Keep an eye out for battery tech news about metal hydrogen batteries. With the recent surge in space technology, we might see more about this battery technology soon.
One of the biggest advantages of this battery type is that they have incredibly high cycling tolerance. Current batteries can tolerate as many as 20,000 cycles, and the theoretical versions of these batteries could have almost unlimited cycling tolerance. That makes these batteries some of the best options for long life or in applications with rapid charge and discharge cycles. Rechargeable versions of these batteries are popular options for space equipment because of their long battery life.
These batteries are also highly overcharge tolerant, though heat management is critical if the battery is overcharged.
