New Iron Cathode Battery Extends Life by 50 Percent
A novel battery type uses a cathode built from an unusual iron form that absorbs more electrons, boosting power. The design promises a lifespan roughly 50 percent longer than current batteries, enhancing energy density and longevity.
Superiron batteries promise longer life and easy manufacture
Israeli researchers at the Israel Institute of Technology report a 50 percent energy increase using a super iron cathode in alkaline batteries. The team stabilized iron(VI) with common cathode solutions, enabling longer high-drain use in devices like portable CD players and potentially powering electric cars. Industry reaction cites vast alkaline battery demand, while commercial release remains years away.
