Abstract:
The synergistic combination of 3-cyano-1,2,4-triazole (CTZ) and 1-(Trimethylsilyl)imidazole (TMSIM), featuring π-donor-acceptor (π-DA) interactions, facilitates the formation of a Li3N-rich solid electrolyte interphase (SEI) with high mechanical strength and ionic conductivity. This interface enables Li|| LiFePO4 (LFP) batteries to maintain 96.74% capacity after 1200 cycles at 5C, offering a promising strategy for fast-charging lithium metal batteries.

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...
