Summary

The global market for rechargeable lithium-ion batteries has risen fivefold to $10 billion a year over the past decade. But 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 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.
