Lithium-Ion Batteries Last 30 Percent Longer With A Silicon Sponge

Batteries are common in the devices we use - everything from electric cars to laptops. Unfortunately the last real breakthrough in battery technology was lithium-ion and it's been 25 years of not much since. We're no longer using a 386 PC but our devices are using that equivalent in battery power. There are efforts to try and get the most performance out of this legacy technology and one effort is replacing the graphite traditionally used in one of the battery's electrodes  with a sponge-like silicon material. Silicon has more than 10 times the energy storage capacity of graphite.  read more
