Battelle Memorial Institute

Contact BMI About This Technology

Technology Marketing SummaryThis technology features cathodes for use in open electrochemical cells and devices comprising the cathodes and open electrochemical cells.DescriptionThe open electrochemical cells generally comprise a cathode, an electrolyte, and an anode. One example cathode comprises a catalyst, an electronic conductor and a hydrophobic gas permeable binder. The open electrochemical cells may function as metal-air batteries.Benefits
  • Metal-air batteries are suitable for use in relatively small, portable, electrically-powered functional devices
  • Partially alleviate gas accumulation and cathode consumption issues typical of primary alkaline batteries
  • Increases mechanical integrity
  • Suitable oxygen permeability
  • Suitable gas permeability to assist in the alleviation of gas accumulation in the open electrochemical cell
Applications and Industries
  • Cellular phones, voice recording and playing devices, watches, motion and still cameras, liquid crystal displays, electronic calculators, IC cards, temperature sensors, hearing aids, pressure sensitive devices and transmitters of various types.
