(a) LiFSI as an electrolyte component in lithium batteries; (b) Schematic of LiFSI action on electrodes to improve film formation and lithium deposition. LiFSI in lithium battery electrolytes boosts stability and cycling, forming protective SEI/CEI layers. Research explores its use in ionic liquids and polymer gels.
As one of the most promising alternatives to LiPF6 salt in a fast-charging electrolyte, the application of high-content lithium bis (fluorosulfonyl)imide (LiFSI) in LiFePO4 batteries has been seriously hindered by a higher thermal runaway risk. However, the mechanism of heat release, which is the most critica
It was concluded that when electrolyte additives are used, LiFSI improves cycle life via a better passivating graphite SEI layer, however some minor self-discharge mechanism that does not irreversibly consume lithium is introduced into the full cell with the use of this salt.
In contrast, the price of LiPF 6 has surged, recently ranging between $87,000 and $95,000 per ton, . Due to its superior performance and decreasing cost, LiFSI is increasingly viewed as a viable alternative to LiPF 6 in battery electrolytes.
With the continued adoption of Li-ion batteries in large-scale and long-term applications such as grid energy storage 1 and electric vehicles, 2 maximizing lifetime is of paramount importance
