SUPERBATTERY HAS LONGER LIFE

摘要

A new class of light, environmentally benign alkaline batteries based on iron stores over 50% more energy than alkaline batteries that are currently available commercially. The "super-iron" batteries, as they are called, were developed by chemistry professor Stuart Licht, research associate Baohui Wang, and postdoctoral research fellow Susanta Ghosh at Technion -Israel Institute of Technology, Haifa [Science, 285, 1039 (1999)]. The nonrechargeable alkaline batteries used in consumer electronic products contain a zinc anode, a manganese dioxide cathode, and a potassium hydroxide electrolyte.
