New nanostructure for batteries keeps going and going

(Phys.org) -- 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 ...

Increasing Electric Car Battery Performance

(PhysOrg.com) -- Researchers have found that by replacing conventional graphite electrodes with silicon nanotube electrodes, lithium-ion batteries can store 10 times more charge.

Silicon solves problems for next-generation battery technology

Silicon – the second most abundant element in the earth's crust – shows great promise in Li-ion batteries, according to new research from the University of Eastern Finland. By replacing graphite anodes with silicon, it ...

Toughened silicon sponges may make tenacious batteries

(Phys.org) -- Researchers at Rice University and Lockheed Martin reported this month that they've found a way to make multiple high-performance anodes from a single silicon wafer. The process uses simple silicon to replace ...

Neutrons explain aging process in lithium ion batteries

A key issue with lithium ion batteries is aging. It significantly reduces their potential storage capacity. To date, very little is known about the causes of the aging effects. Scientists from the Department of Technical ...
