Researchers Work on Safer, Cheaper, and Faster-Charging Lithium Ion Batteries

People use their GPS apps, cameras, and mobile internet to navigate strange cities in search of good coffee, record “selfie” commentary while they wait in line, and upload their videos directly to social media sites while they sip their latte. But no amount of high-tech savvy can save a well-loved device from dying when its battery is drained.
Smartphones suffer from the same basic ailment that plagues solar power plants and wind farms – they lack cheap, reliable, long-life batteries to store large amounts of energy for when the sun goes down, the wind stops blowing, or the device is unplugged for a long time.
“I think almost any application in technology you can think of is currently limited by the battery,” said Amy Prieto, a chemist at Colorado State University who leads a start-up company with the goal of developing a better energy storage device. The group is nearing the prototype phase for a lithium ion battery that should be safer, cheaper, faster-charging, and more environmentally friendly than conventional batteries now on the market. She will present her latest results at the upcoming AVS 60th International Symposium and Exhibition, held Oct. 27 – Nov. 1 in Long Beach, Calif.
