WATER TYPE ELECTROLYTE FOR LITHIUM/SODIUM ION BATTERY AND LITHIUM/SODIUM ION BATTERY CONTAINING THE ELECTROLYTE

摘要

To provide a water type electrolyte for a lithium/sodium ion battery and the lithium/sodium ion battery containing the electrolyte.SOLUTION: In a water type electrolyte for a lithium/sodium ion battery, a hydrophilic nature oxide nanoparticle is uniformly distributed in an aqueous solution of a lithium/sodium ion salt. According to the water type electrolyte for a lithium/sodium ion battery, a potential window of the water type electrolyte can be improved, and the generation of a hydrogen generation side reaction can be processed. Thus, larger low voltage negative electrode can be applied to a battery system of the water type electrolyte, and an energy density of the battery can be improved.SELECTED DRAWING: Figure 1
