Porous metal CELMET™

  • Celmet™ consists of a porous metal body with triangular-prism shaped cells to form a 3D structure.
  • The available materials include not only pure nickel (Ni) but also nickel-based alloys, such as nickel-chromium (Ni-Cr) and nickel-tin (Ni-Sn). These materials are produced in the world’s largest-scale production plant.
Application
  • Current collectors of battery (e.g. NiMH, fuel cell, next generation battery) , Electrodes of hydrogen generator etc.
