Laptop batteries operate for 20 hours thanks to nanowire technology

Experts at Stanford University (USA) have redesigned the Lithium-Ion battery with a semiconductor nanowire structure, allowing the ability to charge power 10 times more than today.

Yi Cui, the school's professor of materials science, and chemistry engineer Candace Chan and five others wrote a project to boost the battery's strength. Technology can also be applied to electric cars because solar energy is more efficient than existing products.

Lithium-Ion batteries currently only store lithium at carbon anodes. Silicon semiconductor anodes can store more energy but tend to fail faster. However, the battery that Cui developed saved lithium in countless nanoscale silicon wires that made molecular bonds unbreakable.
