(PhysOrg.com) -- Researchers have found a way to incorporate silicon into the structure of rechargeable lithium-ion batteries, which are used to power a wide variety of portable electronic devices, including digital cameras and cell phones. The group's method, using a nanowire form of silicon, overcomes the roadblocks that have prevented the use of silicon and may help extend the batteries' lifetimes.
