SEI's Aluminum-Celmet To Make Electric Vehicles 300% More Efficient

Sumitomo Electric Industries (SEI) is a Japanese company that has developed porous aluminum which can potentially boost the efficiency of electric vehicles (EVs) by over 300%. SEI manufactures electric cables, wires and optic-fiber cable. The porous aluminum developed by SEI can be combined with Lithium Ion Batteries to boost their efficiencies by over 3 times. Aluminum Celmet's 3D structure is capable of forming structure with pores which can increase the efficiency by over 300%. Celmet has 80% more pores than any conventional pores material.

SEI also discovered that Aluminum Celmet's electric resistance is substantially lower than Celmet; which is a metal derived from Nickel which is currently used in SEI's NiMH batteries. Replacing the conventional copper foils from the Li-Ion batteries with Aluminum-Celmet, the battery capacity can jump multi-folds.On more advantage is lightness - the specific gravity of Aluminum is about 1/3rd of the Nickel. It also offers greater electrical conductivity. The aluminum-celmet is also known to have more corrosion resistance.

The company has setup a production factory at Osaka to accelerate the development of the material and heading towards mass production.
