Abstract
Composition and method for preparing a chloroaluminate molten salt at room temperature having a wide electrochemical window is provided. The salts include aluminum chloride and an organic chloride salt combined in a mole ratio of about 1-1 and a sufficient amount of alkali metal chloride added thereto to buffer said salts to Lewis acid-base neutrality, which is maintained by the latter additive, which neutrality is necessary for the above wide window. The so-buffered salts being molten at room temperature, provide an improved, high energy electrolyte for light-weight, durable batteries and for other applications.
