MOLTEN SALT CELL

摘要

A problem encountered with a separator used in a molten salt cell is that, due to the unique way in which molten salt cells are used, the separator may be subjected to mechanical, thermal, or chemical stress, giving rise to cracking or rupture, which tends to diminish cell performance due to internal shorting or the like. This molten salt cell is provided with a separator containing 75% or more of a metal oxide, particularly aluminum oxide and/or zirconium oxide. The separator has improved mechanical, thermal, and chemical resistance, is less likely to develop separator-induced internal shorting, and affords stable operation of the molten salt cell for extended periods of time. Moreover, the separator has high thermal stability, and can improve the safety of the molten salt cell.
