Electrolyte Rau Lithium-ion roj teeb

Solute: lithium ntsev feem ntau siv, xws li lithium perchlorate (LiClO4), lithium hexafluorophosphate (LiPF6), lithium tetrafluoroborate (LiBF4). Cov kuab tshuaj: Vim tias lub zog ua haujlwm ntawm lub roj teeb ntau dua li qhov decomposition voltage ntawm dej, lithium-ion roj teeb feem ntau siv cov kuab tshuaj organic, xws li ether, ethylene carbonate, propylene carbonate, diethyl carbonate, thiab lwm yam. Organic solvents feem ntau rhuav tshem cov qauv ntawm graphite thaum them, ua rau nws tev tawm, thiab tsim cov khoom electrolyte interphase (SEI) ntawm nws nto ua rau electrode passivation. Cov kuab tshuaj organic kuj coj cov nplaim taws, tawg thiab lwm yam teeb meem kev nyab xeeb.
