Zinc-Air Batteries,  Portable Power Solutions
  Clean, Green Portable Power Source

The primary fuel source material in the anode of the MetAir™ cells is zinc metal powder derived from recycled Electric Arc Furnace (EAF) dust. EAF is produced as a by-product from steel mills and is classified as a hazardous material. EAF contains roughly twenty percent zinc which is recycled, refined, and treated for use in batteries and other applications. The resulting high purity zinc powder is safe, non-toxic, non-combustible, and environmentally friendly – delivering clean portable power in the MetAir™ Cells. And because these zinc-air batteries contain no added mercury, cadmium, lead or lithium, the replaceable MetAir™ Power Cartridges are considered safe for disposal in the normal waste stream with no special hazardous waste handling required.

MetAir Battery MSDS


The primary (disposable) zinc-air cells are modular and scalable prismatic units, each with a durable plastic case housing. Multi-cell assemblies combined in series or parallel, depending on voltage and current usage requirements, offer a variety of custom form factors:

  • Need a customized, lightweight, mobile power system for military use? 
  • Planning a boating, camping, outdoor sports events or recreational adventure that requires off-grid or emergency back-up power?  

QSI can tailor MetAir™ Cells, based on proprietary zinc-air technology, to meet your portable on-demand energy needs.

The MetAir™ Cells, each individually capable of producing up to 92 amp hours, utilize zinc metal powder, air, and electrolyte to deliver the power or current inside the MetAir™ Ranger system.

The fully-loaded MetAir™ Ranger will hold multi-cell assemblies containing up to 36 disposable zinc-air cells (12-Series, 3-Parallel) in one single 28 lb. stack. The total system energy output can deliver up to 3.5 kilowatt hours or 3500 watt hours of reliable portable power – lasting up to 192 hours or EIGHT days, once activated by exposing to air. Once used, the zinc-air cells are generally considered safe for disposal in the normal waste stream.
