24 seconds: Al-S (aluminum-sulfur) batteries are a promising candidate for the next generation of energy storage devices. Unlike lithium-ion batteries that are commonly used in portable devices such as smartphones, Al-S batteries can hold more charge, are capable of enduring more charge cycles without losing effectiveness, and have less tendency to explode. They also has a big cost advantage since aluminum is the most abundant metal in the earth's crust so extraction will be way less expensive than it is for lithium. Although still in the development phase, significant progress has been made.
