Abstract |
A sulfide-based SEI layer was formed on the surface of a LiNi0.5Mn1.5O4 cathode by using a sulfolane- carbonate mixed solvent electrolyte, which led to an improvement in the electrochemical performance. Moreover, the thermal stability of the LiNi0.5Mn1.5O4 cathode was also significantly improved in the presence of the SEI layer. ARC (Accelerating Rate Calorimetry) tests showed that the self-heating rate of the delithiated LiNi0.5Mn1.5O4 material in the sulfolane- carbonate electrolyte was suppressed.
