Bateri ya Sodium-Ion, Bateri yihuta-Ishaja, Bateri y'ubuzima buramba, Anode ya carbone, ubuhinga bwa bateri ya EV, Umuti wo kubika inguvu, Bateri ziramvye, Ubushakashatsi bwa kaminuza ya Nankai
Igikoresho ca SIB, uburemere bw'ububasha bwinshi, ugushikama kw'ingendo ya bateri, g-C3N4 coating, imipira y'umuyagankuba, uguhingura SEI, amabateri y'uruvyaro rukurikira-
Ihiganwa ry’ubuhinga bwa **ubuhinga bushasha bw’amabateri** ririko rirashuha, kandi amabateri ya sodium-ion (SIBs) ariko araseruka nk’umuhiganwa ukomeye, uramba, kandi ushobora gutwara amahera menshi. Ariko rero, ingorane ikomeye cane ni ugutegura ibikoresho vy’anode bifatanya ugushaja vyihuta n’ubuzima buramba cane.
Icigwa gishasha cakozwe na **Kaminuza ya Nankai** ubu caranesheje iyo nzitizi. Abashakashatsi barahingura ikintu gishasha **carbon anode material** gishobora gutuma ama SIB ashobora guca mu minota mikeyi gusa mu gihe yihanganira inzinguzingu ibihumbi mirongo ataco yononekaye. Ivyo vyoshobora guhindura vyose kuva ku **binyabiziga bikoresha umuyagankuba (EVs)** gushika ku rugero rw'uruzitiro- **uburyo bwo kubika inguvu**.
>**Igiharuro c'ubushakashatsi bwa mbere:** [Gushika ku kubika ivyuma vy'iyon vyihuta cane kandi bikomeye cane biciye ku bikoresho vy'ivyuma bikomeye cane](https://doi.org/10.1002/adma.202509953)

**Ingorane: Kubera iki ama anode ya carbone akeneye guhindurwa
Ibikoresho bishingiye kuri carbone-ni vyo bihambaye mu gukoreshwa mu gukoresha **amabateri ya sodium{1}}ion** kubera ukuntu bikomeye kandi bigura make. Yamara, imiterere y’imigenzo y’ivyuma vy’umuyagankuba irababazwa n’ibi:
* **Ugutwara ion buhoro**, kugabanya **ubushobozi bwo gupima** no gucagura vyihuta.
* **Imirongo idashikamye** n’ivyo bita electrolyte, bituma ubushobozi buzimangana ningoga.
Ishirahamwe rya kaminuza ya Nankai ryaciye rifata ingingo yo gutorera umuti izo ngorane rikoresheje ubuhinga bwo gukurikirana ibintu mu buryo bw’ubuhinga.
**Umuti w'ubuhinga bushasha: g-C3N4 y'imipira y'umuyagankuba ipfutse**
Iryo tsinda ry’abashakashatsi ryakoze igikoresho citwa **CN@HCS**. Ivyo bigereranya nitride ya carbone (g-C3N4) ipfutse ku ruhande rw’ibice vy’umubiri vy’umubiri (HCS)**.
Uyu mubumbe ni inyigisho nziza cane mu buhinga bwa nano-:
1. **Igice c’umubiri gifise umwobo (HCS) Core:** Gitanga ahantu hanini ho gukorana n’ivyo bita sodium-ion (Na+) kandi kigabanya inzira y’ugukwiragira kw’ivyo bita ion, bigatuma umuntu ashobora gucapura vuba.
2. **g-C3N4 Elegitoroni-Igipande kitagira ico gikora:** Ico gipfukisho ni urufunguruzo rwo gushikama. Ikora nk’ingabo ihitamwo, igahagarika neza ibintu bidakenewe hagati y’ivyo bikoresho n’ivyo bikoresho.
**Ibikorwa vy'ubuhinga bw'amashanyarazi**
Ivyo vyavuyemwo vyavuzwe mu kinyamakuru *Advanced Materials* ntaco bimaze atari ibidasanzwe. Igikoresho ca CN@HCS cerekanye:
* **Igipimo kidasanzwe c'Ibikorwa:** Itanga ubushobozi bwinshi mbere no ku rwego rwo hejuru cane rw'uburemere bw'amashanyarazi **40 A g−1**.
* **Ugushikama kw'Ikinyabiziga Kutari bwigere Bubaho:** Yashitse ku **ugusenyuka kw'ubushobozi hafi zero ku nzira 40.000**, ugushikama kw'ibinyabiziga kw'ibinyabiziga vya SIB.
* **Inguvu nyinshi mu gice c’umubiri cuzuye:** Iyo ifatanijwe na cathode ya NFPP kugira ngo ikore igice c’umubiri cuzuye, iyo bateri yarashitse ku **uburemere bw’inguvu budasanzwe bwa 21.600 W kg−1** (bushingiye ku buremere bwose bw’izo electrode zompi).
* **Ivyiyumviro vy'Ugushaja/Ugusohoka:** Igikoresho cuzuye coshobora **gushaja vuba-mu masaha 0.1 (iminota 6)** maze kigasohoka mu buryo budahinduka mu masaha 1 n'ubushobozi bwa Coulombic bwegera 100%.
**Uko Bikora: Ubuhinga buri Inyuma y'Ugushikama**
Ico cigwa kiratanga ubumenyi bwimbitse ku bijanye n’igituma ivyo bintu bikora neza cane:
* **Igishushanyo ca SEI gikomeye:** Igipande ca g-C3N4 kiranywa neza kandi kigabanura FEC (ikintu gisanzwe co kwongerako amazi), kigatuma habaho igihimba kimwe, gikomeye, kandi kidafise ubuzima -igice c'amazi gikomeye (SEI). Iyi SEI ikomeye ikoresha ivyuma bikeyi vy’umuyagankuba kandi ikabuza gukomeza gusenyuka.
* **Ugutwara ivyuma vyihuta:** Uburyo bwinshi bw'ama elegitoroni π-bufatanye muri g-C3N4 buratanga inzira ndende yo gutwara ama elegitoroni n'ama ion vyihuta, bikaba bishoboza **ubushobozi budasanzwe bw'urugero rwo hejuru-**.
* **Ugukingira amakosa:** Ico gipfukisho kiragabanya ukugaragara kw’ibibanza vy’amakosa bikoreshwa n’amashanyarazi ku ruhande rwa carbone, bikaba bigabanya ubushobozi bw’ibikoko bishobora gutera.
**Iciyumviro c'igerageza: Uko Anode ikorwa**
Ku basomyi bacu b’abahinga, inzira y’ugusesangura ni iyi:
1. **Ivyiyumviro vy'imbere vya PPy/PMMA:** Igikoresho ca Pyrrole n'igishushanyo ca PMMA bikoreshwa hakoreshejwe ivyuma vy'imbere (APS) biri munsi ya degre 5 .
2. **HCS Synthesis:** Igikoresho gibanza gihindurwa carbone ku bushuhe bwa degre 700 mu kirere kitagira ico gikora kugira ngo kireme imibumbe y’umuyagankuba irimwo imyobo.
3. **CN@HCS Synthesis:** HCS ivangwa na urea igashushwa gushika ku bushuhe bwa degre 500 , bituma urea ibora kubera ubushuhe maze igahingura ag-C3N4 ku mibumbe ya carbone.
**Insozero n'ingaruka**
Ico gikorwa ku **ama anode y’umuyagankuba akomeye cane** kigereranya itera imbere rikomeye ku buhinga bwa **ubuhinga bwa bateri y’umuyagankuba**. Mu guhingura mu buryo bubereye ag-C3N4-coated hollow carbon structure, abashakashatsi bararemye anode ikora icarimwe ku bintu bitatu bihambaye cane: **umuvuduko, ugushikama, n’ububasha**.
Abanditsi basozera bati: "Iyi nyigisho itanga ubumenyi bushasha ku bijanye n'ugutegura ama anode ashingiye kuri carbone-a SIBs zifise ubuzima buramba cane hakoreshejwe ama electrolytes ashingiye kuri carbonate-."
Ubushobozi bwo kurema amabateri ashobora gushaja mu minota mikeyi kandi akamara imyaka mirongo, bwoshobora kwihutisha cane kwemera **imiti y’inguvu ziramvye** no gutuma **imodoka zikoresha umuyagankuba** zirushiriza kuba nziza kandi zishobora gushikwako kuruta uko vyari bimeze kera.
