Sumitomo Electric Develops Improved Lithium Battery Materials–Aluminum Celmet

Sumitomo Electric has developed a new metal that is adaptable for hybrid car batteries.

The material, Aluminum-Celmet is low in resistance and light and easily processed by cutting or shaping. 

“ … features lead to favorable filling, retaining and current-collecting performance, … recently been adopted as a positive electrode current collector in hybrid vehicle nickel-hydrogen batteries.”

Sumitomo’s studies show that it can increase battery capacity between 1.5 x and 3 x.  Another way to view this is that for a given charge capacity a battery footprint can be 1/3 to 2/3 smaller by volume.
