TAO Zinc-Air-Battery-System

TAO has the goal to develop a new TAO-Zinc-Air-Battery, which is rechargable in five minutes. The new battery for electric cars may have a range of several hundred kilometers and is also useable for stationary storages in houses. This "air breathing" bionic battery is producing the electric current by pumping the zinc-suspension through the battery, in which the zinc-suspension oxidates. At the filling station the suspension will be exchanged and you get a full recharged car in a view minutes. The suspension can be regenerated with solar energy: a complete fuel system without consuming the fluid fuel has been developed. The zinc-suspension is useable over and over again.

The New TAO Zinc Air Battery for mobile and stationary application:

  • rechargeable in 5 minutes
  • non toxic
  • incombustible (not burnable)
  • no CO2
  • regenerative
  • no fossile fuels
  • 100% environmentally friendly
  • sustainable: no consumption of material ( the operating lubricant can be regenerated by (solar) electric power)
  • cost efficient production (no clean room)
  • inexpensive, rife basic material: zinc and air
  • vast market potential

TAO is working in the lab successfully, especially in developing a new air electrode and a current generator - testing the battery stacks. The regeneration of the zinc-suspension has also been proven in the lab. TAO designed and built an own light carbon fibre car for testing the battery under real conditions. TAO plans to set a milestone in the world of the electric cars of the future.

Flying in the stratosphere needs a special energy-management: especially batteries and energy generation must be fail-safe.

The TAO Group scientists research for new alternative systems since years, because there had been no compatible energy storage systems for the SkyDragon High altitude platform at the market. Our experiences in “Flying by light/ solar energy management” (see Solar airship Lotte) are very valueable in this research.

Optimized Air-Electrodes

TAO Technologies GmbH and Fraunhofer IKTS in Germany are developing new air-electrodes for zinc-air-batterie-cells. During the research project TAO and IKTS develop high capacity and cost efficient mixed oxide chemical catalysts (Perowskit). This catalysts in an optimized design will be tested and measured as a "full-electrochemical cell" or a "half electrochemical cell". As published in scientific publications the mixed oxides in Perowskit-crystal form or in Spinell-crystal form have an enormous potential in reaching high current density and catalytic activity, which the commercially available air electrodes from established manufacturer do not reach until now. If this potential can be used in zinc-air-battery-cells this will be a big development step for electromobiles.

Research cooperation:

  • TAO Technologies GmbH
  • Fraunhofer IKTS Hermsdorf

The results of the research activities of the new Perowskit air-electrode will be implemented in the TAO Battery.
