Advantage
1」Current collector
Large surface area and high porosity improve battery performance.
-
High porosity can increase the amount of active material per unit area, and improve cell capacity.
-
Compared to sintered metal foam, Celmet™ increases productivity of the electrode due to paste filling system.
2」Grease Filter
Large surface area improve oil-collection performance and high porosity reduce the pressure loss.
-
Compared to baffle filter, Celmet™ has higher collection performance due to its large surface area.
-
The material (nickel) can be repeatedly used by alkaline washing.
-
Compared to ceramic filter, Celmet™ is durable and can be used repeatedly.
-
Compared to metal fiber or ceramic, Celmet™ has less chipping and mechanical degradation, improving safety.
-
Compared to baffle filter of stainless steel, Celmet™ has better fireproof performance due to lower thermal conductivity.
-
The weight is one-third of baffle filter.
3」Catalyst Carrier
Large surface area increase catalyst carrier amount and high porosity reduce the pressure loss.
-
Compared to ceramics, the amount of catalyst carrier is increased due to its large surface area.
-
Compared to porous alumina, Celmet™ has better in balance between low pressure loss and high catalyst carrier.
-
Compared to ceramic filter, Celmet™ is durable and can be used repeatedly.
4」Electrodes of water electrolysis
Large surface area increase the amount of hydrogen generation.
-
Hydrogen generation capability is proportional to surface area of electrode.
-
Compared to lath or mesh, Celmet™ reduces hydrogen overvoltage.
-
Compared to lath or mesh, the amount of hydrogen generated at the same current density is increased.
