Game-Changing Anode Protection Platform Enabling All Ultra-High Energy Lithium Metal Batteries for Space and Commercial Applications

DALLAS, June 5, 2026 /PRNewswire/ -- Solidion Technology Inc. ( STI ) , an advanced battery technology solutions provider, today announced a patented breakthrough in lithium metal battery technology that removes the key stumbling blocks against full-scale commercialization of lithium-sulfur, lithium-air, and anodeless lithium metal batteries.

This technology further solidifies Solidion's ( STI ) leadership position in powering the rapidly expanding space and lunar economy. Solidion's ( STI ) lithium battery-enabling platform will deliver reliable, high-performance power storage for satellites, low-Earth orbit (LEO)-based AI data centers, crewed spacecraft, and future lunar infrastructure.

This lithium metal anode protection platform, protected by 30+ patents, addresses the following three technical barriers that have thus far prevented large-scale implementation of ultra-high energy lithium metal batteries: (1) continued reactions between the electrolyte and lithium metal; (2) lithium dendrites that could penetrate through the separator or solid-state electrolyte layer, creating internal shorting and thermal runaway; and (3) large gaps between the lithium metal layer and the solid-state electrolyte that diminish battery performance.

The strategic importance of Solidion's ( STI ) battery technology may be briefly summarized below:

For the space industry: the lithium metal batteries, as illustrated in the diagram below, are well-suited for powering all space infrastructure and space vehicles.Down-to-earth applications: Beyond space, Solidion's ( STI ) platform powers electric vehicles, drones, robots, and AI data center UPS systems.Domestic supply chain security: With over 385 patents, U.S.-based green graphite production ramp, and silicon-anode leadership, Solidion ( STI ) supports American space leadership by reducing reliance on foreign battery materials — a critical consideration for national security-oriented space programs.About Solidion Technology, Inc.
