제목 | Electrochemical intercalation host materials for calcium ion batteries (칼슘 이온 전지용 전기화학적 탈삽입이 가능한 호스트 소재) |
초록 | Recently, calcium-ion batteries (CIBs) have received attention as one of the post LIBs. The abundance of calcium resources can make CIBs cost effective. Calcium has a standard reduction potential of 0.17 V above lithium that makes CIBs capable of a higher energy density compared to other multivalent ions. In addition, calcium ion has a lower charge density than other multivalent ions, which may lead to relatively faster diffusion in a host material. To use calcium metal as a negative electrode in a cell, suitable cathode materials that store calcium ions are required. However, only a few cathode materials are reported so far to show electrochemical activity in calcium-containing electrolytes. In this presentation, some exploratory experimental results of electrochemical intercalation chemistry of divalent ions of calcium ion will be presented with several host materials in aqueous electrolytes as well as non-aqueous electrolytes. |
