Air Energy builds solid‑state lithium‑air batteries that deliver over 1,000 Wh/kg, roughly four times the energy density of conventional lithium‑ion cells, while being lightweight and non‑flammable. The cells draw oxygen from ambient air and operate at room temperature, enabling longer range, higher payload, and multi‑day endurance for electric aircraft, drones, maritime platforms, and critical backup power systems.

Problem
Current lithium‑ion batteries limit electric aviation, autonomous platforms, and defense systems due to low energy density, heavy weight, and safety concerns such as flammable liquid electrolytes. These constraints reduce range, payload capacity, and mission endurance, preventing longer‑duration operations and new capabilities.
Solution
Air Energy develops solid‑state lithium‑air batteries that achieve up to four times the energy density of conventional lithium‑ion cells, delivering more than 1,000 Wh/kg. By drawing oxygen directly from ambient air and using a solid electrolyte, the cells eliminate internal oxygen storage and liquid electrolytes, resulting in a lightweight, non‑flammable design. The technology provides faster charging, higher efficiency, and a safer operating profile at room temperature. Higher specific energy and reduced mass enable longer range, greater payload, and multi‑day endurance for aircraft, drones, maritime surveillance, and critical backup power systems. Air Energy moves from validated science to pilot manufacturing and system integration in partnership with government and commercial customers.
Target Audience
Primary customers are manufacturers and operators of electric aircraft, long‑range drones, autonomous maritime surveillance systems, and defense or critical‑infrastructure entities requiring high‑energy, lightweight, and safe battery solutions.
