Lithium-air

The only certainty of electric car technology is that nobody is really certain of our future path. Dozens of different battery technologies are under development all around the world to fix the common battery limitations--limited energy density, heavy weight, long recharging times--and one such path is that of lithium-air batteries. Computer and technology company IBM is taking the lithium-air route, and explains the workings of the battery in the video above. The basic concept of a battery is to turn a chemical reaction into an electrical output. A lithium-air battery draws oxygen from the...
