PERLA

Advanced Silicon-Anode Battery Module for Space Transportation

PERLA is Stellar Exploration's cutting-edge project designed to revolutionize power sources for future space missions. By integrating advanced silicon-anode lithium-ion technology, including innovations from Amprius Technologies, PERLA delivers exceptional energy densities of 400–500 Wh/kg—far surpassing traditional battery technologies. This breakthrough promises significant weight reduction and enhanced power for long-duration space missions and human exploration.

In just 12 months, we will develop and test a high-performance battery module/string that meets the rigorous demands of space applications. The module will undergo thorough validation to ensure its readiness for in-space use, with a focus on lifecycle, efficiency, and thermal management.

With a modular design, the PERLA battery module will seamlessly integrate into existing satellites & space transportation systems, offering a reliable, lightweight, and cost-effective power solution for the next generation of space missions.

PERLA battery performance details

PERLA battery assembly with Li-ion Si Anode 18650 cylindrical cells compared to using generic space Li-ion 18650 cell

– Reach up to 20% higher energy density with same sized battery
– Better longevity of cells improves battery lifespan significantly thanks higher number of charge/discharge cycles(can be even higher, depending on mission configuration)
– Quicker recharge thanks to Si Anode cell 3x higher charging current
– Larger discharge currents can provide higher peak power to the spacecraft thanks to 4x lower internal resistance
– Overall offers high customization based on customer requirements
