Intshayelelo

Iibhetri zeSodium-ion luhlobo lwebhetri etshajwayo esebenzisa ii-ion zesodium njengezithwali zokutshaja. Njengeebhetri zeLithium-ion, iibhetri zeSodium-ion zigcina amandla ombane ngokuhamba kwee-ion phakathi kwee-electrodes ezilungileyo nezingalunganga. Ezi bhetri ziyaphandwa kwaye ziphuhliswa njengenye indlela enokubakho endaweni yeebhetri zeLithium-ion, ngenxa yokuba iSodium ininzi kwaye ingabizi kakhulu xa ithelekiswa neLithium.

Iibhetri zeSodium-ion zinokusetyenziswa kwizicelo ezahlukeneyo, kubandakanya ukugcinwa kwamandla kwimithombo evuselelekayo njengamandla elanga nawomoya, izithuthi zombane, kunye nokugcinwa kwamandla kwinqanaba legridi. Abaphandi basebenza ukuphucula uxinano lwamandla, ubomi bomjikelo, kunye neempawu zokhuseleko zeebhetri zeSodium-ion ukuze zibe lukhetho olufanelekileyo olunokukhuphisana nazo.Iibhetri ze-ion ze-lithium eziyi-18650kwayeIibhetri ze-ion ze-lithium ezingama-21700kwilixa elizayo..

I-Voltage yeBhetri yeSodium-Ion

I-voltage yeebhetri ze-sodium-ion ingahluka ngokuxhomekeke kwizinto ezithile ezisetyenzisiweyo ekwakheni kwazo. Nangona kunjalo, iibhetri ze-sodium-ion zihlala zisebenza nge-voltage ephantsi xa kuthelekiswa neebhetri ze-lithium-ion.

Nangona i-voltage eqhelekileyo yebhetri ye-lithium-ion ingahluka ukusuka kwi-3.6 ukuya kwi-.7 volts ngeseli nganye, iibhetri ze-sodium-ion zihlala zine-voltage ejikeleze i-2.5 ukuya kwi-3.0 volts ngeseli nganye. Le voltage iphantsi yenye yeengxaki ekuphuhliseni iibhetri ze-sodium-ion zokusetyenziswa kwezorhwebo, njengoko ichaphazela uxinano lwamandla kunye nokusebenza kwebhetri xa kuthelekiswa nezinye iindlela ze-lithium-ion.

Abaphandi basebenza ngokukhutheleyo ekuphuculeni i-voltage kunye nokusebenza kweebhetri ze-sodium-ion ukuze zikwazi ukukhuphisana ngakumbi neebhetri ze-lithium-ion ngokubhekiselele kubuninzi bamandla, ubomi bomjikelo, kunye nokusebenza kakuhle ngokubanzi.

Ubuninzi bamandla ebhetri yeSodium-Ion

Ubuninzi bamandla eebhetri ze-sodium-ion bubhekisa kubungakanani bamandla anokugcinwa kumthamo othile okanye ubunzima bebhetri. Ngokubanzi, iibhetri ze-sodium-ion zinobunzima obuphantsi xa kuthelekiswa neebhetri ze-lithium-ion.

Iibhetri zeLithium-ion zihlala zinobunzima obuphezulu bamandla, yiyo loo nto zisetyenziswa kakhulu kwizixhobo ze-elektroniki eziphathwayo kunye nezithuthi zombane apho amandla okugcina amandla abaluleke kakhulu. Iibhetri zeSodium-ion, kwelinye icala, zinobunzima obuphantsi bamandla ngenxa yobukhulu kunye nobunzima bee-ion zeSodium xa kuthelekiswa nee-ion zeLithium.

Nangona amandla azo engaphantsi, iibhetri ze-sodium-ion ziyaphandwa kwaye ziphuhliswa njengendlela enokubakho endaweni yeebhetri ze-lithium-ion ngenxa yobuninzi kunye nexabiso eliphantsi le-sodium. Abaphandi basebenza ekuphuculeni amandla eebhetri ze-sodium-ion ngokuphucula izixhobo kunye noyilo lweebhetri ukuze zikwazi ukukhuphisana ngakumbi kwizicelo ezahlukeneyo, ezifana nokugcinwa kwamandla kunye nezithuthi zombane.

Isantya sokutshaja kwebhetri yeSodium-Ion

Isantya sokutshaja kweebhetri ze-sodium-ion sinokuhluka ngokuxhomekeke kwizixhobo ezithile kunye nobuchwepheshe obusetyenziswayo ekwakheni kwazo. Ngokubanzi, iibhetri ze-sodium-ion zinezinga lokutshaja eliphantsi xa kuthelekiswa neebhetri ze-lithium-ion. Oku kungenxa yokuba ubukhulu obukhulu kunye nobunzima obukhulu bee-ion ze-sodium kwenza kube nzima ngakumbi ukuba zihambe ngokufanelekileyo phakathi kwee-electrodes ngexesha leenkqubo zokutshaja nokukhupha.

Nangona iibhetri ze-lithium-ion zaziwa ngokukwazi kwazo ukutshaja ngokukhawuleza, iibhetri ze-sodium-ion zinokufuna ixesha elide lokutshaja ukuze zifikelele kumthamo opheleleyo. Abaphandi basebenza ngokukhutheleyo ekuphuhliseni izixhobo ezintsha kunye nobuchwepheshe bokuphucula isantya sokutshaja kweebhetri ze-sodium-ion kunye nokuzenza zikhuphisane ngakumbi neebhetri ze-lithium-ion.

Ukuqhubela phambili kwizixhobo ze-electrode, ii-electrolytes, kunye noyilo lwebhetri kuyahlolwa ukuphucula isantya sokutshaja kweebhetri ze-sodium-ion ngelixa kugcinwa ukusebenza kwazo ngokubanzi, ubomi bomjikelo, kunye neempawu zokhuseleko. Njengoko uphando luqhubeka, sinokubona uphuculo kwisantya sokutshaja kweebhetri ze-sodium-ion, nto leyo eyenza ukuba zisebenze ngakumbi kuluhlu olubanzi lwezicelo.
