Solidion Technology (STI) shares extended gains in Friday's premarket activity after the company announced a patented extreme-climate battery platform designed for space operations, artificial intelligence data centers in low Earth orbit, and lunar infrastructure.
The company's shares rose more than 21% in recent premarket activity.
The power storage system based on graphene actively manages cell temperatures, allowing the hardware to operate between -80 and 80 degrees Celsius, the company said Thursday, when its shares closed up 357% in regular trading.
The company is also developing solid-state lithium-ion and lithium-sulfur batteries with non-flammable materials to provide higher energy-to-weight ratios for crewed spaceflights.
The battery hardware surpassed 500 charge cycles at -40 Celsius during testing to support long-term lunar surface power grids and exploration rovers, it added.
