Aluminium Bids to Vie With Lithium in Battery Wars
February 1st, 2012 ›
A recent news item in Science highlights recent advances in battery research at the Energy Materials Center at Cornell.
We love our rechargeable lithium-ion batteries. They drive our cell phones, laptops, power tools, electric cars, and countless other gadgets. And their numbers are rising. The global market for lithium-ion batteries has risen fivefold to $10 billion a year over the past decade. Still, lithium-ion batteries may face tough times ahead. Lithium supplies are limited, and the cost of the metal has skyrocketed in recent years. So researchers are on the lookout for novel battery chemistries. At the meeting, researchers from New York described materials that could pave the way for making rechargeable batteries from aluminum. Because aluminum is one of the most abundant elements on the planet, and is less prone to catching fire than lithium is, it could pave the way to cheaper and safer rechargeables.
