In the never-ending quest to make our batteries more efficient, scientists have a new breakthrough: incredibly thin sheets of metal that form a flower that can hold a lot of power.
Batteries have resisted the blazing progress of Moore’s Law, the observation that the number of transistors packed on computer chips--and thus the processing power--doubles every 18 months. The batteries that power all those super fast chips have only managed to perform about 5% to 8% better each year (except for the rare breakthroughs in new battery chemistries).
Scientists are split on whether such meager improvements in energy density should be the norm, or if transformational leaps of 10 to 100 times above today’s performance are possible.
