IBM's Battery 500 Project
Turkish defense company ASELSAN signed a collaborative development agreement concerning research and development of metal-air battery technologies with IBM Research.
According to the press release, the goal is to increase the energy density 5 times and range to 800 km (500 miles), however IBM has been promising such a breakthrough for several years now and there is still a long way to go.
"Metal-Air Batteries to be developed will provide at least 5 times more storage capacity than current Li-Ion Batteries while preserving the same weight. These Metal-Air batteries will deliver more storage capacity at a lower cost than existing batteries, which will significantly reduce the cost of energy. Consequently, these new batteries will be a critical automotive component in resolving range issues for electric vehicles. Today, a family car can scarcely travel 160 km (100 miles) using existing Li-Ion batteries, whereas the new Metal-Air technology batteries will increase this range up to at least 800 km (500 miles). "
It's however interesting that the military sector began to work with metal-air technology, which probably means that someone out there is dreaming of an electric tank or maybe an electric fighter jet.
