Second Wind: Air-Breathing Lithium Batteries Promise Recharge-Free Long-Range Driving–If the Bugs Can Be Worked Out

Researchers predict a new type of lithium battery under development could give an electric car enough juice to travel a whopping 800 kilometers before it needs to be plugged in again–about 10 times the energy that today's lithium ion batteries supply. It is a tantalizing prospect –a lighter, longer-lasting, air-breathing power source for the next generation of vehicles–if only someone could build a working model. Several roadblocks stand between these lithium–air batteries and the open road, however, primarily in finding electrodes and electrolytes that are stable enough for rechargeable battery chemistry.
