Chemists from Hiroshima University have developed organic radical batteries that are re-chargeable and continue to function at below-freezing temperatures. The Hiroshima team uses a new synthesis method to make an organic battery. The team has a step into one of the hardest problems of batteries – how to function well when cooled down.
Transporting power sources in the coldest places may be easier with a new re-chargeable, non-metallic battery from Japan. This “eco battery” could provide portable sources of power in environments like refrigerated factories or winter environments.
The specific model prototyped by the Hiroshima University team has greater voltage than previously reported styles from other research groups around the world. The method used to create this battery is an improvement on a report from the same Hiroshima University laboratory earlier in 2016.
The team’s research paper has been published by The Bulletin of the Chemical Society of Japan.
Many of today’s electrical devices use a lithium-ion battery. Lithium-ion batteries are safer than standard lithium metal batteries, but both styles rely on metal, a finite resource that is in decreasing supply. The same problem of decreasing supply exists for copper and cobalt batteries, like the traditional AA size batteries in TV remote controls.
