Safety concerns posed by flammable electrolytes in lithium-ion batteries (LIBs) continue to impede their widespread use. Incorporating non-flammable phosphate-based electrolytes has emerged as a promising solution to prevent combustion incidents in LIBs. Nonetheless, the profound bond between Li+ and phosphate compounds results in the formation of a predominant solid electrolyte interphase (SEI) that offers inadequate electronic protection. Consequently, this hinders efficient Li+ intercalation at the graphite (Gr) anode when employing electrolytes with elevated phosphate content.
The persistent threat of safety hazards associated with the use of flammable electrolytes in lithium-ion batteries (LIBs) stands as a formidable obstacle hindering their broader adoption. A compelling strategy to address this challenge involves the integration of non-flammable phosphate-based electrolytes. This approach has shown considerable promise in mitigating the risk of combustion incidents within LIBs. However, the inherent strong affinity between Li+ ions and phosphate constituents gives rise to the development of a prevalent solid electrolyte interphase (SEI) that lacks sufficient electronic shielding. As a consequence, the effectiveness of Li+ intercalation at the graphite (Gr) anode is compromised, particularly in scenarios where electrolytes with high phosphate concentrations are utilized.
The issue of safety pertaining to flammable electrolytes within lithium-ion batteries (LIBs) represents a significant hurdle impeding their extensive deployment. An innovative solution to this dilemma involves the utilization of non-flammable electrolytes based on phosphates, which have demonstrated their efficacy in preventing combustion incidents in LIBs. Nevertheless, the substantial interaction between Li+ and phosphate components leads to the formation of a dominant solid electrolyte interphase (SEI) characterized by limited electronic shielding capabilities. This phenomenon detrimentally affects the process of Li+ intercalation at the graphite (Gr) anode, particularly in instances where electrolytes containing high levels of phosphates are employed.
