A lithium salt used as an additive in the 0.5-2% range rather than as the primary salt. It forms a thin, low-resistance interphase layer on both the anode and cathode surfaces; this dual-sided effect extends cycle life while limiting the rise in cell resistance. A widely used additive in commercial cells.
Key Features
- Forms an interphase layer on both anode and cathode surfaces (dual-sided effect)
- A low-resistance interphase limiting the rise in cell internal resistance
- Marked cycle life benefit at low proportions of 0.5-2%
