Batteries in space
Chemical batteries are usually used in outer space as a means of power generation. Batteries generate voltage by creating an electric potential between chemicals with different properties. Rechargeable batteries can store electricity channeled from an outside source, causing a reverse reaction between these chemicals. The table below lists common battery types used in space.
| Battery type | Formula | Specific energy (W*hr)/kg |
