Volume 4, Issue 3, 15 March 2023, 101321 Conductive filler-based solid polymer electrolytes are excellent candidates for the large-scale production of solid-state lithium-ion batteries. However, the transport and conduction mechanisms of lithium ions in such solid polymer electrolyte systems remain largely unrevealed.
Li-ion transport through the interface between the electrolyte and the electrodes affects the overall conductivity of solid-state batteries and the chemical stability of the interface. “Point-to-point” ion diffusion may occur at the interface due to poor interfacial contact.
Conductive networks are integral components in Li-ion battery electrodes, serving the dual function of providing electrons to the active material while its porosity ensures Li-ion electrolyte accessibility to deliver and release Li-ions, thereby ultimately determining the electrochemical performance of the battery.
To mitigate this problem, researchers have added lithium salts or ionic liquid into MOFs or COF to improve ion conductivity. Although ionic conductivity can be improved in this way, it redcues the lithium-ion transference number even down to ∼0.2.
Thus, the hopping process with higher lithium concentration increases local energy minimum and decreases activation energy. And results in better ionic conductivity. Comparing LAGP and LAGPY systems, the increase in the lithium-ion concentration, resulted in 5-fold high ionic conductivity.
The ultimate goal is to have the ionic conductivity of SSEs reach 10 −3 –10 −2 S cm −1 at room temperature, which is comparable to that of liquid electrolytes. Table 1. Comparison of different solid-state Li-ion electrolytes Current solid polymer electrolytes are developed mainly based on the segment motion mechanism.
