Calcium batteries are an emerging, next generation energy storage technology undergoing intense research toward viable operation. A key aspect in their development is plating and stripping of a calcium metal anode in suitable electrolytes. Herein, we report that calcium can be plated and stripped at room temperature in an ionic-liquid-based electrolyte. Thick continuous deposits (∼20 μm) of crystalline calcium are plated and stripped over 10 cycles to areal capacities of 2.2 mAh cm^–2 at a current density of 0.56 mA/cm². This work presents ionic liquids as viable electrolytes for calcium anodes to enable redox activity for calcium batteries.

离子液体电解质在室温下电镀和汽提钙

钙电池是一种新兴的下一代能量存储技术，正在朝着可行的运行进行深入研究。它们发展的关键方面是在合适的电解质中电镀和剥离钙金属阳极。本文中，我们报道钙可以在室温下在基于离子液体的电解质中镀覆和剥离。在0.5个mA / cm ²的电流密度下，在10个循环中镀覆并剥离厚厚的连续结晶沉积物（约20μm），面积容量为2.2 mAh cm ^-2。这项工作提出了离子液体作为钙阳极的可行电解质，以使钙电池具有氧化还原活性。
