Calcium-ion batteries (CIBs) have become an attractive and promising candidate for sustainable energy storage systems. Unfortunately, conventional electrolytes do not allow the reversible plating/stripping of Ca2+ ion on Ca metal surface, which challenges the development of CIBs. Since the ionic size of Ca2+ ion (100 pm) and Na+ ion (102 pm) are nearly identical, researches on CIBs can utilize the achievements of sodium ion batteries (SIBs). We show that some cathode materials including NH4V4O10 and KFeFe(CN)6 utilized in SIBs also have good performances in CIB systems. Meanwhile, metal-organic framework materials can be applied as anodes and reveal better cyclability than metal-organic complex materials. When a solution of 1M Ca(ClO4)2 in acetonitrile is applied as an electrolyte, it demonstrated different performances due to many factors (active materials’ sizes, current collectors, total resistances) for the CIBs system. |
