  About Zinc-Air Batteries

Unlike most common disposable and rechargeable batteries used today, zinc-air batteries are powered by exposing zinc metal to oxygen from the air to generate electricity.  The zinc-air battery user literally removes a tab to break the seal, allowing air to flow into the cell, activating the battery and generating an electric current. 

The MetAir™ battery technology results in batteries with very high energy densities.  Because air from the atmosphere is a reactant and not packaged within the battery, a cell has more room to store and use zinc fuel to increase capacity or run time.  

As a result, MetAir™ Cells have a higher energy-to-weight ratio than any other commercially available primary batteries and a shelf life of up to 5 years.  Zinc-air batteries are also considered environmentally friendly, clean and green energy sources; they are non-combustible and non-toxic, containing no added mercury, cadmium, lead or lithium.

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.

 

QSI Nanocatalysts and Capacity

A multi-billion dollar global industry, catalysts are essential to the world's industrial production. As much as 90% of all chemical processes utilize catalysts (petroleum refining, pollution abatement, and production of fuels and chemicals) and 60% of all consumer and industrial products (fertilizers, plastics, pharmaceuticals, and batteries) are made using catalysts. Catalysts are now seen as a preferred way to improve process efficiency, lower costs, increase output, use less energy, and meet both performance and environmental standards. This is placing a strong emphasis on the development of new catalysts with higher activity, increased longevity, and reduced environmental and/or health impact.

A nanometer (nm) is one billionth of a meter, or 1000 times smaller than the diameter of a human hair, or roughly the size of a marble when compared to the earth. QSI catalysts typically measure 5-25 nm.

A catalyst is a material that helps make chemical reactions happen faster. The higher the surface area of the catalyst, the faster the chemical reaction.

QSI's advanced catalysts have superior properties including their spherical shape, oxide layer, and very large surface area. This translates into greater efficiency in the generation, storage, and use of energy.
Leveraging our patented, automated, highly scalable, and environmentally safe Gas Phase Condensation (GPC) process, we manufacture a number of high-quality metals, bi-metallic alloys, and catalysts at the nano scale including Iron, Silver, Copper, Nickel, and Manganese. We also offer custom dispersions and several specialty metals and catalysts including Gold, Palladium, Aluminum, and Tin.

We have eight dedicated reactors currently in operation with a manufacturing facility capacity of ~500 kilos per month. Based on demand, we are able to quickly scale and adjust production runs to satisfy our customers' advanced material needs and delivery timelines.

In addition, we leverage our deep technical knowledge and process chemistry expertise to offer custom dispersions and integrated catalytic solutions for the energy storage and chemical sectors.

Catalyst Footnote: A catalyst is a substance that increases the rate of a chemical reaction by reducing the required activation energy. In addition to speeding up certain chemical reactions, catalysts also can be used to alter the temperature and pressure at which various thermal and elctro-chemical reactions take place and, thus, make them more efficient. Nanocatalysts represent the convergence of catalysts, a mature technology, with a new one, nanotechnology. Nanocatalysts are nanoscale materials (typically under 100 nanometers in size) that have been subjected to nanoscale structural modification in order to enhance their catalytic activity by increasing the active surface area, resulting in unique physical properties with superior performance.

The extent of the catalyst market may not be apparent to the casual observer because catalysts are mostly used in intermediate processing steps, but catalysts are a multi-billion dollar industry. Current global catalyst markets are in excess of $12 billion annually. Nanocatalysts sales are projected to reach $6.0 billion by 2015 and will play a critical role in reducing costs and increasing efficiency in the generation, storage, and usage of energy.

Clean Energy / High Efficiency Chemical Production - Ammonia Synthesis

A multi-billion dollar global industry, catalysts are essential to the world's industrial production. As much as 90% of all chemical processes utilize catalysts (petroleum refining, pollution abatement, and production of fuels and chemicals) and 60% of all consumer and industrial products (fertilizers, plastics, pharmaceuticals, and batteries) are made using catalysts. Catalysts are now seen as a preferred way to improve process efficiency, lower costs, increase output, use less energy, and meet both performance and environmental standards. This is placing a strong emphasis on the development of new catalysts with higher activity, increased longevity, and reduced environmental and/or health impact.

QSI catalysts have the potential to benefit multiple multi-billion dollar process applications in the refining, petrochemical, chemical, and pharmaceutical industries. Currently the lead application and commercialization focus is ammonia synthesis, a highly critical and energy-intensive process. The $100B+ of ammonia produced annually consumes more than 2% of the world's energy supply. Approximately 85% of this output is used as agricultural fertilizer for both food (supplying 50% of all human protein consumed), and non-food crops including biofuel feedstocks. In addition, ammonia generation produces 400 million tons of greenhouse gasses annually, or 1.6% of the world's total carbon dioxide emissions. By lowering the reaction temperature and pressure and increasing overall conversion efficiency, QSI's turbo-charged iron catalysts have the potential to increase ammonia production output per plant by up to 20% (Note: the ammonia industry considers 5% to be a "game changer"). At scale, this breakthrough promises not only significant energy and infrastructure savings to the 100 year old Haber-Bosch process, but also compelling improvements in the net output of both food and fuel production. The Company believes it can generate 100+ million dollars in annual revenue within the ammonia and specialty chemicals industry. Product commercialization is underway with several industry leaders.

  1. Are QSI’s zinc-air batteries rechargeable?

    MetAir™ Cells are primary (non-rechargeable) cells which can be conveniently used and replaced much like replacing the ink toner cartridge in a printer.  Once discharged (completely utilized), the MetAir™ Power Cartridge is replaceable and can be disposed of in the normal waste stream.

    Relying on combustible fuels, or solar- or wind-generated power in an “off-the-grid”, emergency power outage, or military situation can be dangerous, unpredictable, and inefficient.  The MetAir™ Ranger PPS is lightweight, safe, and reliable for emergency back-up power needs – day or night – when diesel generators, solar, or wind are not available for recharging batteries.

  2. What is the typical voltage of zinc-air chemistry?

    QSI’s zinc-air chemistry provides 1.4V Open Circuit Voltage (OCV) and 0.9V-1.25V per cell under load or closed circuit voltage (CCV).

  3. How does the discharge voltage curve slope relative to lead acid and lithium-ion batteries?

    The zinc-air discharge curve is completely flat 90% of the discharge time and then drops off sharply toward the end of the battery life, whereas lead acid and lithium-ion will tend to decrease voltage gradually throughout the discharge period.  Alkaline and lead acid batteries suffer from low rate self-discharge that decrease shelf life dramatically.  When lead acid batteries are stored fully charged, they suffer from a permanent capacity loss over time and must be maintained (re-charged) every three months to ensure a full state of charge and operational readiness.

  4. What is energy-to-density/weight ratio of the zinc-air chemistry?

    The MetAir™ Ranger PPS is about the size of a single deep cycle (heavy duty) lead acid marine battery, yet it weighs roughly half as much and provides more than EIGHT times the equivalent energy density per kilogram.  This chemistry offers specific energy (energy density) of up to 440 watt-hours per kilogram (Wh/Kg).  It offers the highest energy/weight ratio of any commercially available primary/disposable or rechargeable battery.

  5. What are the current delivery capabilities of zinc-air chemistry?

    Delivery capabilities range from 500 milliamps, 1 amp, 2 amps, 3 amps and 4 amps per cell, or up to 40mA/cm2 in a complete cell.

  6. What is the shelf life of a sealed zinc-air cell or battery?

    A sealed MetAir™ Power Cartridge offers an unprecedented shelf life and performance warranty of up to 5 years before initial use in the original airtight wrapper.  The self-discharge rate is less than 2% per year (sealed). Once activated (exposed to air), the battery should be used within one month.

  7. Can a user stop the discharge of an active zinc-air cell or battery once it has been activated?

    Yes, if properly re-sealed to cut-off the air supply, you can slow the discharge rate and re-use the battery again for up to two months.

  8. Where is zinc-air technology most commonly used today?

    Zinc-air batteries are currently used for hearing aids, watches, telecommunications equipment, ocean buoys, railway remote signaling, and military applications.

  9. Does conventional fuel gauge technology (for lead acid, nickel, or lithium batteries) work with zinc-air?

    Standard battery fuel gauge technology does not work for zinc-air because of the constant discharge curve. A custom low cost battery management system was designed to read the actual capacity left in the battery based on usage.

  10. Does zinc-air require United Nations (UN) or Department of Transportation (DOT) approval for commercial shipment?

    No. Because they are non-toxic and non-combustible, zinc-air batteries are approved by the Department of Transportation (DOT) for travel / transport via air, land, and sea with no further permissions needed.
