Fecha de publicación: | feb-2016 | Editor: | Nature Publishing Group | Citación: | Nature Materials 15(2): 169–172 (2016) | Resumen: | The development of a rechargeable battery technology using light electropositive metal anodes would result in a breakthrough in energy density1. For multivalent charge carriers (Mn+), the number of ions that must react to achieve a certain electrochemical capacity is diminished by two (n = 2) or three (n = 3) when compared with Li+ (ref. 2). Whereas proof of concept has been achieved for magnesium3, 4, 5, the electrodeposition of calcium has so far been thought to be impossible6 and research has been restricted to non-rechargeable systems7, 8, 9, 10. Here we demonstrate the feasibility of calcium plating at moderate temperatures using conventional organic electrolytes, such as those used for the Li-ion technology. The reversibility of the process on cycling has been ascertained and thus the results presented here constitute the first step towards the development of a new rechargeable battery technology using calcium anodes. | Versión del editor: | http://dx.doi.org/10.1038/nmat4462 | URI: | http://hdl.handle.net/10261/148078 | DOI: | 10.1038/nmat4462 | ISSN: | 1476-1122 |
