What kind of batteries does a space station use?

The International Space Station uses rechargeable lithium-ion batteries (initially nickel-hydrogen batteries) to provide continuous power during the eclipse part of its orbit.

Can batteries be used in the harsh environment of space?

Developing safe energy storage for use in the harsh environment of space. Batteries for aerospace applications are a technological challenge. They need to be higher performance and safer than terrestrial batteries, while still being able to operate in some very harsh environments.

Why did NASA replace lithium-ion batteries on the Space Station?

In 2017, NASA began the process of replacing the nickel-hydrogen batteries on the Space Station with lithium-ion ones. Nickel-hydrogen batteries were initially used in space technology because of their long battery life and ability to withstand many charge and discharge cycles without significant degradation.

How does the International Space Station use solar energy?

Using the International Space Station as an example, the batteries used to power the station are recharged with solar energy from the sun and the energy stored is used when it is in orbital darkness — when the station is in the earth’s shadow and not in direct sunlight.

Should space batteries be safer than terrestrial batteries?

They need to be higher performance and safer than terrestrial batteries, while still being able to operate in some very harsh environments. Research into newer battery chemistries as well as the development of safe and rugged battery assemblies for space are an important role for NASA’s Glenn Research Center.

Are batteries used in space dangerous?

Batteries used in space undergo extensive research, testing, and development to an even greater degree than batteries used on earth. In such high risk situations, the failure of batteries is extremely dangerous. The process of changing batteries can also be a taxing mission.
