Capacity, weight and price of the battery are the big challenges facing the electric car. Researchers at Sumitomo have developed a porous, sponge-like metal called “Aluminum-Celmet.” It promises to triple the capacity of lithium-ion batteries.
If battery size is the problem, then Aluminium-Celmet can reduce battery volume to one-third to two-thirds. Want to know how it works?
“Celmet is a porous metal made from nickel or nickel chrome alloy. The porous metal manufacturing process comprises electro conductive coating to plastic foam, followed by nickel plating and plastic foam removal by heat treatment.”
