Sodium-Ion: The Safer, Smarter Energy Solution

At Saltra Batteries, we’re redefining energy storage with sodium-ion technology—a lithium-free alternative that’s safer, more sustainable, and ready for scale. Our Zerithium series is built on advanced electrochemistry that delivers reliable performance across solar, EV, and industrial applications.

How Sodium-Ion Batteries Work

Sodium-ion batteries operate on the same basic principle as lithium-ion; ions shuttle between the anode and cathode during charge and discharge cycles. But instead of lithium, we use sodium—a far more abundant and environmentally friendly element.

Key Components:

  • Anode: Hard carbon or sodium titanium phosphate
  • Cathode: Sodium layered oxides or Prussian white compounds
  • Electrolyte: Nonflammable sodium-based solution
  • Separator: High thermal stability polymer membrane
