A research team at Hanyung University in South Korea, led by Professor Cho Jaephil (pictured), have made a breakthrough in battery technology that has the potential to extend the life of a lithium ion battery by 800%. This is made possible by the use of a three-dimensional porous silicon core to replace the graphite cathode material in standard lithium ion batteries, which can store eight times the amount of lithium ions.
If successful, this technology will improve longevity for all kinds of portable devices ranging from cell phones to cameras and laptops. Currently, our most commonly used devices only last for a few hours max when in use, so the possibility of being able to use them for 16 or even 32 hours on a single charge is definitely a big deal. The Hanyang researchers have applied for the patents for their battery prototype so we may see some new developments on this soon.
