Novel silicon nanostructure extends battery life

For more than a decade, scientists have tried to improve lithium-based batteries by replacing the graphite in one terminal with silicon, which can store 10 times more charge. But after just a few charge/discharge cycles, the silicon structure would crack and crumble, rendering the battery useless. Now a team led by materials scientist has found a solution: a cleverly designed double-walled nanostructure that lasts more than 6,000 cycles, far more than needed by electric vehicles or mobile electronics.

Novel silicon nanostructure extends battery life

Templates made from polymer nanofibers enable the formation of long-lived silicon nanostructures that store ten times as much charge as do graphite battery terminals.
