(Lithiam Chachitsulo Anode) gawo la zigawo zatsopano za Anion

Soning Enterrolyte Interphase (sei) imagwiritsidwa ntchito kwambiri pofotokoza gawo latsopanoli lopangidwa pakati pa mawonekedwe ndi electrolyte pakugwira ntchito. Kuchulukitsa kwamphamvu kwambiri (Li) mabatire achitsulo ali osokonezeka kwambiri ndi Dendric Litium Lalified wotsogozedwa ndi osafanana ndi seki. Ngakhale zili ndi mwayi wapadera kwambiri kukonza kufanana kwa chivindikiro cha lifiya, pogwiritsa ntchito, zotsatira za Anion-SEI sizabwino. Posachedwa, gulu lofufuzira qhang qiang kuchokera ku yunivesite ya Tsinghua akufuna kugwiritsa ntchito anion receptors kuti isinthe mawonekedwe a electrolyte kuti apange sei yokhazikika ya Anion-DEI. Tris (Pentafluorophenyl) Borane anion receptor (TPFPB) ya ma atoron a boron amalumikizana ndi Bis (Fluorosulfoons) Anion (Fsion (FSI-) kuti muchepetse kukhazikika kwa FSI-. Kuphatikiza apo, pamaso pa TFPBb, mtundu wa ion masango (agg) a FSi- m'ma ekitilolyte asintha, ndikucheza ndi ai. Chifukwa chake, kuwonongeka kwa FSI- kamalimbikitsidwa kutulutsa li2s, komanso kukhazikika kwa sei-eiond sei kumachitika.

Sei imapangidwa ndi zolipiritsa zolipiritsa za electrolyte. Kuphatikizika ndi kapangidwe ka sei kumayendetsedwa makamaka ndi kapangidwe ka electrolyte, ndiko kuti, kulumikizana pakati pa zosungunulira, anion, ndi hi. +. Kapangidwe ka ma electrolyte sikusintha kokha ndi mtundu wa zosungunulira ndi mchere wamchere, komanso ndi kuchuluka kwa mchere. M'zaka zaposachedwa, electrolyte wambiri (hce) ndi electolyte yapamwamba kwambiri (LHCE) awonetsa zabwino zapadera (LHCE) zawonetsa zabwino zapadera zokhazikitsa anyezi a Lithiamu pazitsulo. Chiwerengero cha molar to solumure mchere (chochepera 2) ndi aenions amadziwitsidwa mu gawo loyambira la Li + Ndondomeko ya sesi imalamulidwa ndi anyezi mu Hce ndi Lcece, yomwe imatchedwa Anion-Sei. Ngakhale kuti anali kugwira ntchito mokongola kukhazikika pansanja ya lithiamu yachitsulo, anion-anion omwe alipo ndi osakwanira pamisonkhano yothandiza. Chifukwa chake, ndikofunikira kupititsa patsogolo kukhazikika ndi kufanana kwa Anion-Wochokera ku sei kuti muthane ndi zovuta zomwe zili pansi pa zinthu zenizeni.

Andeon mu mawonekedwe a cip ndi agg ndiye mtsogoleri wamkulu wa Antaond SEI. Mwambiri, gulu la zigawo la madera limayendetsedwa mosapita m'mbali ndi mamolekyulu osungunulira komanso osasunthika ndipo sangathe kucheza nawo mwachindunji ndi anyezi. Chifukwa chake, njira zatsopano zoyambira kapangidwe ka ma Aleonic electrolytete polumikizana mwachindunji ndi anions amayembekezeredwa kwambiri.
