Longer Battery Life for Smartphones?

iStock/Thinkstock(STANFORD, Calif.) — Research at Stanford University could lead to an answer for one of the biggest complaints from consumers about their smartphones: short battery life.

In a paper published in the journal Nature Nanotechnology, researchers said they’ve designed a lithium-metal anode that boosts the energy storage capacity by as much as 400 percent.

“Some call it the Holy Grail. It is very lightweight and it has the highest energy density,” Yi Cui, an associate professor in Stanford’s Department of Chemistry, told Forbes. “You get more power per volume and weight, leading to lighter, smaller batteries with more power.”

The Stanford team includes former U.S. Energy Secretary Steven Chu. More research is needed but the advance could lead to much longer battery life for many products, including electric cars.
