Outline of Final Research Achievements

Low-melting alkali metal molten salt has possibility of a novel electrolyte of lithium secondary battery due to its specifically low melting point of 100 degree or less. This molten salt shows stable charge-discharge curves and good rate performance in a lithium battery cell. In this study, we discussed about the specific rate performance. In the result, the specific rate performance is caused by charge transfer resistance between the molten salt and electrodes, which dominates the charge transfer of lithium ion in the battery cell.
