4 FAQs about Energy storage batteries used in space stations

Are lithium ion batteries good for space missions?

In recent decades, lithium-ion (Li-ion) batteries have become the preferred choice for powering space missions, replacing older nickel-based and silver-zinc battery chemistries. Their high energy density, long cycle life, and superior weight-to-power ratio make them ideal for space applications.

Why do spacecraft need a battery?

Space exploration demands high-performance, reliable, and long-lasting power sources. From rovers exploring Mars to satellites orbiting Earth, spacecraft rely on advanced battery technology to survive the harsh conditions of space.

Which spacecraft uses lithium-ion batteries?

The James Webb Space Telescope (JWST) uses lithium-ion batteries to store energy during orbital maneuvers. The Osiris-Rex spacecraft, which collected samples from asteroid Bennu, used lithium-ion batteries to power critical instruments.

Which battery chemistries are used in space missions?

Depending on the nature of the space mission, several other battery chemistries have historically been used (see Figure 3). For example, if operation in extreme temperatures is required, lithium-sulfur dioxide and lithium thionyl chloride batteries are good choices since they can function from -55°C to 65°C and -55°C to 80°C, respectively.
