Super - Carbon Anode Ihamye Imbaraga Byihuse - Kwishyuza Sodium - Bateri ya Ion hamwe na 40.000-Cycle Lifespan
Sodium - Bateri ya Ion, Byihuta - Kwishyuza Bateri, Bateri Yubuzima Burebure, Carbon Anode, Ikoranabuhanga rya Batiri, Ikoreshwa ryububiko bwingufu, Bateri zirambye, Ubushakashatsi bwa kaminuza ya Nankai
SIB ibikoresho bya anode, ubwinshi bwingufu, ingufu za cycle za bateri, g - C3N4 gutwikiriye, imyuka ya karubone yuzuye, imiterere ya SEI, bateri ikurikira -
Irushanwa rya ** igisekuru kizaza cya tekinoroji ya batiri ** irashyuha, kandi sodium - bateri ion (SIBs) zigaragara nkumuntu ukomeye, urambye, kandi uhenze - uhatanira guhangana. Nyamara, ikibazo gikomeye ni ugutegura ibikoresho bya anode bihuza kwishyurwa byihuse na ultra - igihe kirekire.
Ubushakashatsi butangaje bwo muri ** Nankai University ** bwatsinze iyi nzitizi. Abashakashatsi bakoze igitabo gishya cya ** carbone anode ** ituma SIBs yishyuza muminota mike mugihe yihanganira ibihumbi icumi byikurikiranya kandi nta kwangirika. Ibi birashobora guhindura ibintu byose kuva ** ibinyabiziga byamashanyarazi (EV) ** kugeza kuri gride - igipimo ** sisitemu yo kubika ingufu **.
>** Ubushakashatsi bwibanze: **

** Ikibazo: Impamvu Carode Anode ikeneye kuzamurwa
Ibikoresho bya Carbone - nibyo mukandida wambere kuri ** sodium - ion ya batiri ya anode ** kubera gukura kwabo nigiciro gito. Nyamara, imiterere gakondo ya karubone irababara:
* ** Buhoro buhoro transport ya **, kugabanya ubushobozi bwibiciro ** no kwishyuza byihuse.
* ** Imigaragarire idahindagurika ** hamwe na electrolyte, biganisha kubushobozi bwihuse.
Itsinda rya kaminuza ya Nankai ryiyemeje gukemura ibyo bibazo hamwe nubuhanga bwakozwe mubuhanga.
** Igisubizo gishya: g - C₃N₄ Yubatswe Yubusa ya Carbone **
Itsinda ryubushakashatsi ryateguye ibikoresho byiswe ** CN @ HCS **. Ibi bisobanura nitride ya karubone (g - C₃N₄) yubatswe hejuru ya ** Carlow Carbon Spheres (HCS) **.
Igishushanyo nigishushanyo mbonera muri nano - injeniyeri:

2. ** g - C₃N₄ Electron - Inert Layeri: ** Iyi coating nurufunguzo rwo gutuza. Ikora nkingabo yatoranije, irwanya neza reaction zidakenewe hagati ya electrode na electrolyte.
** Imikorere ya Electrochemical Performance **
Ibisubizo byatangajwe mu kinyamakuru * Ibikoresho bigezweho * ntakintu gito kidasanzwe. Anode ya CN @ HCS yerekanye:
* ** Imikorere idasanzwe Igipimo: ** Yatanze ubushobozi buhanitse ndetse no mubucucike buri hejuru cyane bwa ** 40 A g⁻¹ **.

** Uburyo Bikora: Ubumenyi Inyuma Yumudugudu **
Ubushakashatsi butanga ubumenyi bwimbitse kumpamvu ibi bikoresho bikora neza:
. Iyi SEI ikomeye ikoresha electrolyte nkeya kandi ikarinda kwangirika bikomeje.

** Umwanzuro & Ibisobanuro **
Aka kazi kuri ** superbable karubone anode ** yerekana gusimbuka gukomeye kuri ** sodium - tekinoroji ya batiri ya ion **. Mugushushanya mu buryo bushyize mu gaciro ag - C₃N₄ - yubatswe yubatswe ya karubone yuzuye, abashakashatsi bakoze anode icyarimwe itanga icyarimwe mubice bitatu bikomeye: ** umuvuduko, ituze, nimbaraga **.
Abanditsi bashoje bati: "Ubu bushakashatsi butanga ubumenyi bushya mu iterambere rya karubone - ishingiye kuri anode ya ultralong - ubuzima SIBs ikoresheje karubone - ishingiye kuri electrolytike".
Ubushobozi bwo gukora bateri zishyuza muminota kandi zimara imyaka mirongo zishobora kwihutisha cyane kwemeza ** ibisubizo birambye byingufu ** kandi bigatuma ** ibinyabiziga byamashanyarazi ** byoroha kandi bigerwaho kuruta mbere hose.
