Lithium-ion batteries (LIBs) are integral to modern technology, yet their relianceon flammable liquid electrolytes poses significant safety challenges, especially inelectric vehicles and large-scale energy storage systems. This paper presents thedevelopment of flame-retardant electrolytes utilizing the Define-Measure-Analyze-Design-Optimize-Verify (DMADOV) methodology to enhance bothsafety and performance of LIBs. The study initiates by defining the correlationbetween the properties of organic solvents and electrochemical stability,focusing on the overcharging risks that can induce thermal runaway. Throughsystematic measurement and analysis of candidate components, critical factorsinfluencing the quality of flame-retardant electrolytes are identified. The designphase prioritizes the establishment of solid electrolyte interface (SEI) conditionsfor γ-butyrolactone (γ-BL), ensuring the electrolyte’s performance and stability inLIBs. The optimization phase further refines the SEI formation conditions toaddress performance challenges identified during initial design, incorporatingrelated manufacturing processes. The final verification phase confirms thealignment of the flame-retardant electrolyte composition with optimized SEIconditions, establishing a viable electrolyte range for practical applications. Thestudy demonstrates that the use of γ-BL markedly reduces the explosion risk dueto overcharging. The final verification phase confirms the alignment of the flameretardantelectrolyte composition with optimized SEI conditions, establishing aviable electrolyte range for practical applications. Significantly, this studyemphasizes the importance of robust SEI design in developing flameretardantelectrolytes with high-flash-point organic solvents like γ-BL,supported by validation experiments on patented technology. Theseadvancements not only enhance the safety profile of LIBs but alsodemonstrate the potential for improved battery performance, paving the wayfor broader applications in energy storage solutions.
