Calcium ion battery chemistry with double the capacity of lithium ion now has a potential battery electrode solution. (Link is to a pdf download.) Toyohashi University of Technology (TUT) researchers have demonstrated calcium ion batteries (CIBs) using pigment based electrodes such as Prussian Blue and its analogues. The CIBs showed excellent cyclability of discharge and […]

Researchers from Empa and ETH Zurich have discovered an alternative to the lithium ion battery chemistry with the “fool’s gold battery”. They believe the prime potential lies in giant storage batteries that could be built at low cost and used for stationary storage in buildings or next to power plants. Maybe not for electric vehicles […]

Pacific Northwest National Laboratory (PNNL) is announcing a new zinc-polyiodide redox flow battery that uses an electrolyte that has more than two times the energy density of the next-best flow battery and may exceed lithium-ion. The new zinc-polyiodide redox flow battery is described in the team’s paper published in Nature Communications. The zinc-polyiodide redox energy […]
