In our first episode of our new videos series Aqueous Energy, we sit down with Dr. Adam Weisenstein, CTO of Æsir Technologies, to explore how nickel-zinc batteries are moving from lab scale to Department of Defense deployment.

We discuss:

  • How Æsir is refining nickel and zinc from mine tailings to secure domestic supply.

  • Why nickel-zinc batteries can survive bullet penetration tests.

  • The role of recyclability and manufacturing simplicity in scaling aqueous chemistries.

  • Æsir’s new zinc horizons: sodium-zinc, lithium-zinc, and more.

Watch the full conversation and see how Æsir is proving that aqueous zinc batteries aren’t just experimental — they’re ready for real-world impact.
