Towards building next-generation batteries using a pigment electrode

Toyohashi Tech researchers have demonstrated calcium ion batteries (CIBs) using pigment electrodes such as Prussian blue and its analogues. The CIBs showed excellent cyclability of discharge and charge in a calcium-based organic electrolyte. This is thought to derive from strong atomic bonds in Prussian blue structures, which possess movable pathways for large-sized ions in three dimensions. Such unique structures have excellent potential for application in newly designed batteries.
