Lithium BIS (Trifluoromethathanesulphonyl) imide 丨 CAS CAS 90076-65-6

1. Cov roj teeb lithium-ion (loubs)

Litrsi yog siv los ua cov ntsev lithium hauv cov roj electrolyte ntawm cov roj teeb lithium-ion, feem ntau yog hloov lipl₆. Nws txhim kho:

Ionic conductivity

Thermal ruaj khov ntawm electrolyte

Voj voog lub neej ntawm lub roj teeb

Kev Nyab Xeeb, los ntawm kev txo cov roj tsim thiab decompostion txaus ntshai

Nws yog sib haum nrog:

Kua electrolytes (carbonate-based solvents)

Khoom polymer electrolytes (piv txwv li, peo raws)

Gel polymer electrolytes

Cov Ntawv Thov:

Cov Neeg Siv Khoom Electronics

Cov Tsheb Hluav Taws Xob (EVS)

Zog cia Tshuab (ETS)

2. Solid-xeev thiab polymer electrolytes

Litrsi yog cov Lithium qhov zoo tshaj plaws rau cov khoom siv polymer electrolytes vim:

Muaj peev xwm dissociation siab (pub dawb lithium ions)

Tsawg sib cuam tshuam nrog polymer matrices

Nws yog dav siv nrog polyethylene oxide (pyo) lossis lwm yam roj teeb tsis muaj zog (SSBS

3. Supercapacitors

Litfsi tau ua haujlwm hauv electrolyte ntawm electrochemical capacitors (supercapacitors) rau:

Siab dua ionic kev sib koom tes

Txuas voltage ntau

Txhim Kho Lub Zog Hluav Taws Xob

Nws tuaj yeem siv ob lub aqueous thiab tsis muaj aqueous.

4. Ionic kua thiab electrolyte additive

Litrefsi yog soluble nyob rau hauv thiab tau tshaj tawm ntau yam ntawm ionic kua, uas tau siv nyob rau hauv:

Advanced Zog Khoom Khoom Siv

Electrochemical kev ua

Electroplating thiab electropolishing

Nyob rau hauv cov ntsiab lus no, litfsi pab txhawb cov nplaim tsawg, tsis muaj ntau volatility, thiab lub sijhawm electrolyte.

5. Electrochnical li

Nws tseem muaj txiaj ntsig hauv:

Lithium Hlau Roj Teeb

Lithium-sulfur (li-s) roj teeb

Lithium-huab cua (li-o₂) roj teeb

Redox ntws roj teeb

Litfsi pab txhim kho cov ionic conductivity hauv cov dityectric constant media thiab ruaj khov interfaces (piv txwv li, li-hlau anode / electrolyte).

6. CATALYYY thiab Synthesis

Hauv qee cov tshuaj lom neeg tshuaj lom, litfsi tau siv:

Raws li kev txhawb nqa electrolyte hauv electrosynthesis

Hauv iionic ua kua tsim

Raws li theem-hloov tus neeg sawv cev lossis acid catalyst hloov

✅ Electrochicical Ruaj

Litrsi muaj ntau lub qhov rai electrochemical (txog 5.5v), ua rau nws haum rau high-voltage cathrodes thiab tom ntej no cov roj teeb tom ntej.

✅ Cov kev ruaj khov hluav taws xob ruaj khov

Thermally ruaj khov txog 300 degree, ua kom zoo dua li lipf₆, ua rau nws zoo tagnrho rau cov haujlwm siab thiab kev nyab xeeb roj teeb.

✅ Tsawg Hygroscopicity thiab tsis yog-corrosiveness

Tsis zoo li Lipf₆, litfsi tsis tso hf (hydrofluoric acid) thaum muaj kev pheej hmoo ntawm kev xeb thiab txhim kho lub neej ntawm cov electrodes.

✅ ionic conductivity

Txhim kho cov kev thauj khoom hauv ob qho tib si ua kua thiab cov khoom siv-lub xeev, uas txhim kho lub zog tawm thiab them nyiaj rov qab.

✅ Tshuaj Sib Xws

Tau tshaj cov kuab tshuaj, polymers, thiab electrode cov ntaub ntawv, pub ntau yam tsim ntawm electrolytes.

Txo cov kev phiv tawm

Nws ruaj khov (tfsi⁻) minimizes sab kev tawm tsam, SEI txheej kev ua tsis haum, thiab thermal decomposition hauv kev sib piv nrog lwm cov ntsev lithium.
