Isingeniso

Amabhethri e-sodium-ion awuhlobo lwebhethri elishajekayo elisebenzisa i-sodium ion njengabathwali bokushaja. Ngokufana namabhethri e-lithium-ion, amabhethri e-sodium-ion agcina amandla kagesi ngokuhamba kwama-ion phakathi kwama-electrode aqondile noma angalungile. Lawa mabhethri asacwaningwa ngenkuthalo futhi athuthukiswa njengendlela engase ibe enye yamabhethri e-lithium-ion, ngenxa yokuthi i-sodium igcwele kakhulu futhi ingabizi kakhulu uma kuqhathaniswa ne-lithium.

Amabhethri e-sodium-ion anamandla okusetshenziswa ezinhlelweni ezihlukahlukene, okuhlanganisa ukugcinwa kwamandla emithonjeni evuselelekayo efana namandla elanga nawomoya, izimoto zikagesi, nokugcinwa kwamandla ezingeni legridi. Abacwaningi basebenzela ukuthuthukisa ukuminyana kwamandla, impilo yomjikelezo, nezici zokuphepha zamabhethri e-sodium-ion ukuwenza abe yinketho esebenzayo engaqhudelana nayo.18650 amabhethri e-lithium ionfuthi21700 amabhethri e-lithium ionesikhathini esizayo..

I-Voltage yebhethri ye-Sodium-ion

I-voltage yamabhethri e-sodium-ion ingahluka kuye ngezinto ezithile ezisetshenziswa ekwakhiweni kwawo. Kodwa-ke, amabhethri e-sodium-ion ngokuvamile asebenza nge-voltage ephansi uma kuqhathaniswa namabhethri e-lithium-ion.

Nakuba i-voltage evamile yebhethri ye-lithium-ion ingasukela ku-3.6 kuya ku-.7 volts ngeseli, amabhethri e-sodium-ion ngokuvamile anebanga lamandla kagesi eliphakathi kuka-2.5 kuya ku-3.0 volts ngeseli. La mandla ombane aphansi angenye yezinselelo ekuthuthukiseni amabhethri e-sodium-ion ukuze asetshenziswe ngenjongo yokuthengisa, njengoba athinta ubuningi bamandla kanye nokusebenza kwebhethri uma kuqhathaniswa nezinye izindlela ze-lithium-ion.

Abacwaningi basebenza ngenkuthalo ekuthuthukiseni i-voltage nokusebenza kwamabhethri e-sodium-ion ukuze abenze baqhudelane kakhulu namabhethri e-lithium-ion ngokwenani lamandla, impilo yomjikelezo, nokusebenza kahle kukonke.

Ukuminyana kwamandla ebhethri ye-Sodium-ion

Ukuminyana kwamandla amabhethri e-sodium-ion kubhekisela enanini lamandla elingagcinwa kuvolumu ethile noma isisindo sebhethri. Ngokujwayelekile, amabhethri e-sodium-ion anomthamo omncane wamandla uma kuqhathaniswa namabhethri e-lithium-ion.

Amabhethri e-lithium-ion ngokuvamile anomthamo omkhulu wamandla, yingakho evame ukusetshenziswa emishinini ye-elekthronikhi ephathekayo nasezimotweni zikagesi lapho umthamo wokugcina amandla ubalulekile. Amabhethri e-sodium-ion, ngakolunye uhlangothi, anomthamo ophansi wamandla ngenxa yobukhulu obukhulu nesisindo sama-ion e-sodium uma kuqhathaniswa ne-lithium ion.

Naphezu kokuqina kwawo okuphansi kwamandla, amabhethri e-sodium-ion ayacwaningwa futhi athuthukiswe njengendlela engase ibe enye yamabhethri e-lithium-ion ngenxa yobuningi nezindleko eziphansi ze-sodium. Abacwaningi basebenzela ukuthuthukisa ukuminyana kwamandla amabhethri e-sodium-ion ngokusebenzisa intuthuko ezintweni zokwakha kanye nokwakheka kwebhethri ukuze abenze baqhudelane kakhulu ezinhlelweni zokusebenza ezahlukahlukene, njengokugcina amandla nezimoto zikagesi.

Isivinini sokushaja sebhethri ye-Sodium-Ion

Ijubane lokushaja lamabhethri e-sodium-ion lingahluka kuye ngezinto ezithile kanye nobuchwepheshe obusetshenziswa ekwakhiweni kwawo. Ngokuvamile, amabhethri e-sodium-ion anezilinganiso zokushaja ezihamba kancane uma kuqhathaniswa namabhethri e-lithium-ion. Lokhu kungenxa yokuthi usayizi omkhulu nesisindo esisindayo sama-ion e-sodium kwenza kube inselele kakhulu kuwo ukuhamba kahle phakathi kwama-electrode phakathi nezinqubo zokushaja nokukhipha.

Nakuba amabhethri e-lithium-ion aziwa ngamakhono awo ashesha kakhulu ukushaja, amabhethri e-sodium-ion angase adinge izikhathi zokushaja ezinde ukuze afinyelele umthamo ogcwele. Abacwaningi basebenza ngenkuthalo ekuthuthukiseni izinto ezintsha kanye nobuchwepheshe bokuthuthukisa isivinini sokushaja kwamabhethri e-sodium-ion futhi bawenze aqhudelane kakhulu nabalingani be-lithium-ion.

Ukuthuthuka kwezinto zokwenziwa kwe-electrode, ama-electrolyte, nokwakheka kwebhethri kuyahlolwa ukuze kuthuthukiswe isivinini sokushaja samabhethri e-sodium-ion kuyilapho kugcinwa ukusebenza kahle kwawo konke, impilo yomjikelezo, nezici zokuphepha. Njengoba ucwaningo luqhubeka, singabona ukuthuthuka kwejubane lokushaja kwamabhethri e-sodium-ion, okuwenza asebenze kangcono kuhlelo olubanzi olubanzi.
