Lithium is a very soft silvery metal, and can be cut with a knife just like butter. Lithium tarnishes quickly in the air, and will turn black within seconds. It is the lightest metal. Its density is only 0.53 g/cm^3, about the same as pine wood. Lithium is light enough to float in water.
I think the reason they like lithium in batteries is because of both its weight, it is the lightest metal, and it's size, the ion is the smallest of elements in its class, so you can pack more ions on a plate in the battery per electrode area, and so get higher charge density.
