What is CELMET?

SCROLL

Celmet™ consists of a porous metal body whose frame has three-dimensional network structure like sponge. Materials available include not only Ni (nickel) but also alloy-types of Ni-Cr, Ni-Sn, Al* and Cu*, produced in the largest scale production plant in the world. Compared to sintered metal and metal fiber, Celmet™ has much higher porosity of maximum 98% and flexibility (elasticity).

The cell size ranges in 8 levels from 0.45 to 3.2 mm, and excellent workability enables easy processing such as cutting and pressing. Utilizing these unique features, Celmet™ has been mainly adopted as electrodes of Ni-MH batteries for hybrid vehicles.

In the emerging “hydrogen society”, Celmet™ is expected to be widely applied to new fields, such as structural parts of fuel cell for stationary and automotive uses as well as electrodes of hydrogen generators etc. Sumitomo are proud to contribute to the global environment and energy infrastructure.

Characteristics

  1. 1Porous metal with continuous pores

    Celmet™ consists of a porous metal body whose structure is a three-dimensional network structure. Compared to sintered metal, it has less clogging, airflow resistance and pressure loss.

  2. 2Large surface area

    The specific surface area can be maximized by controlling the pore size and thickness.
    Ex.) Celmet™ has higher specific surface area of ​​up to 8 times that of a flat metal plate.

    Large surface area

  3. 3Large porosity
    (max 98%)

    High porosity is maintained even if pressed.
    Ex.) When pressed down to half the thickness: the porosity is kept at 90%. When pressed down to one tenth the thickness: the porosity is kept at 50%.

    *Porosity means the ratio of the volume of the space to the total volume.
