Researchers involved in the PolyZion project are developing a zinc-plastic battery, that should reportedly be lighter, less expensive and longer-lasting than current batteries

While today's lithium-ion, lead acid, and nickel metal hydride batteries may offer far better performance than their predecessors, they are still not perfect - they're heavy, expensive, and have been known to short circuit and catch fire. Now, however, scientists involved in the PolyZion research project are developing zinc-plastic batteries for use in hybrid and electric vehicles. Their aim is to produce a rechargeable battery that is lighter, cheaper, safer, greener and better-performing than anything currently available.

According to the PolyZion website - "The research programme combines fundamental material and process advances in ionic liquids, rechargeable zinc electrodes, ultra-fast pulse charge injection techniques and conducting polymers, as well as constructing prototype battery units for industry standard testing. The resulting battery device will be low cost, have low environmental impact and have the energy and power density necessary to compete with alternative battery technologies in the HEV and EV markets."

Because the zinc-plastic battery would incorporate environmentally sustainable electrolytes, it would be easier on the planet to produce. Unlike lithium-ions, it also wouldn't be prone to catching fire on impact. Its charge-discharge efficiency would be greater than 90 percent after 1,000 cycles ... or at least, that's the plan.

Partners in the mostly-European EUR 3.5 million (US$4.7 million) PolyZion project include the University of Leicester, C-Tech Innovation, Fundacion CIDETEC, Celaya Emparanza y Galdos SA (Cegasa), the University of Porto, KEMA Nederland BV, AE Favorsky Irkutsk Institute of Chemistry, Institute de Recherche d'Hydro-Québec, and Rescoll.

Sounds great...but the article doesn\'t say what stage this development has reached -or when it might yield results.

Is this a report of a new research project for which funding has now been approved and on which work is about to be started? Or is there some evidence of prior results that justify further exploration...and what timescale are we looking at?

I\'d like to get excited abut this but so far I don\'t seem to have enough justification!


people have always been striving for a lighter, better, battery. Sounds like someone had an idea and decided to make a story about it before they actually created anything....

I\'ve got to agree. Sounds like they have a goal, maybe even a plan. Good luck to them.


I get all \'charged up\' just thinking about it! Yet another battery tech proposal. 8-p
