Lithium secondary battery cell

Abstract

The present invention provides a lithium secondary battery cell includes a packaging component having a positive current collector, a negative current collector, and a glue frame, to encapsulate an electrochemical reaction system. The electrochemical reaction system includes a non-Newtonian fluid electrolyte, which is composed of lithium tetrachloroaluminate (LiAlCl4) as the salt and sulfur dioxide (SO2) as the ligand. This configuration minimizes the residual space within the battery cell, allowing saturated vapor pressure to be achieved through the evaporation of only a minimal amount of the ligand for gas-liquid phase equilibrium, thereby maintaining normal battery operation. Furthermore, the ligand-clamping zone is provided at st least one the material interfaces within the electrochemical system to effectively address the electrolyte depletion zones associated with the non-Newtonian fluid electrolyte. Additionally, the non-Newtonian fluid electrolyte undergoes self-decomposition between
