Stereax Solid State Batteries

Miniature solid state battery technology for active medical implanted devices, small wearable and industrial IoT sensors.

We are manufacturing Stereax, our line of ultra-thin, mm-scale, safe and rechargeable solid state batteries which contain no liquid or polymer components.

Stereax enables disruptive product designers looking for a long life (1000s recharges), low leakage (nA) and miniature power source (first product will be 20 mm3) with rectangular form factor similar to ICs.

Features of the Stereax M300:

  • Thickness: 1.0 mm
  • Footprint: 3.6 mm x 5.6 mm
  • Capacity: 300 µAh
  • Pulse power: 12 mW (0.1 s)
  • Cycle life: >1000 cycles (50% DoD)
