Thermal stability analysis of nitrile additives in LiFSI for lithium-ion batteries: An accelerating rate calorimetry study

Mukarram Ali, Siyoung Park, Asif Hassan Raza, Cheolhee Han et autres

Although lithium-ion batteries (LIBs) are extensively used as secondary storage energy devices, they also pose a significant fire and explosion hazard. Subsequently, thermal stability studies for LiPF 6 - and LiFSI-type electrolytes have been conducted extensively. However, the thermal characteristics of these …

Diluent-mediated interfacial reactions in localized-high-concentration electrolytes for fast-charging lithium-ion batteries

Seungsoo Park, Hongjun Chang, Hyuntae Lee, Minhong Lim et autres

The “marionette” effect of various diluents in localized-high-concentration electrolytes subtly controls solvent and additive interactions and refines interfacial chemistry for enhancing Li-ion battery performance, particularly in extreme conditions.

Fire-Inhibiting Nonflammable Gel Polymer Electrolyte for Lithium-Ion Batteries

Jihong Jeong, Mideum Kim, Hyeju Shin, Hosik Lee et autres

Herein, we present a gel polymer electrolyte (GPE) improving nonflammability of lithium-ion batteries (LIBs) by blocking radical-initiated chain reactions which cause thermal runaway and finally fire issues. The polymer that makes up the nonflammable GPE was (1) soluble in carbonate electrolytes, (2) …
