Flexible battery, no lithium required: Lab creates thin-film battery for portable, wearable electronics

Scientists have created a thin, flexible film that combines the best qualities of batteries and supercapacitors. Chemists developed a flexible material with nanoporous nickel-fluoride electrodes layered around a solid electrolyte to deliver battery-like supercapacitor performance that combines the best qualities of a high-energy battery and a high-powered supercapacitor without the lithium found in commercial batteries today.
