Abstract:
Ether-based electrolyte promotes robust LiF/LiNO-rich solid-electrolyte interphases (SEIs) with favorable interfacial conduction and accommodation, thus decreasing operation temperatures of Li metal batteries to -40 °C. At -30 °C, the Li‖Ni0.85Co0.05Al0.1O2 battery achieves >80% retention (130 mA h g-1) of its room-temperature capacity, and presents stable cycling over 100 cycles.

Ionic Bonding and Electron Transfer
Ionic Bonds
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.
Opposing Charges Hold Ions Together in Ionic Compounds
Ionic bonds are reversible electrostatic interactions between ions...
