However, researchers believe there is still room for discussion. A group of scientists at the Department of Energy’s Pacific Northwest National Laboratory’s Chongmin Wang claim that when added, Nickel reduces the speed of battery discharge. They mapped the individual elements of electrodes made of Lithium-Nickel-Manganese oxide […]

What's most interesting about his discovery is that the three metals form a very light alloy, about 40% lighter than a Lithium Ion battery pack at the same size (for example, a Prius battery weights 317 kg, while this hydrogen tank would only weight 200 kg).
