Izivakashi zivakashela imikhiqizo yebhethri ye-sodium ion evela enkampanini yaseShayina embukisweni wokuqala we-China International Supply Chain Promotion Expo.Emsebenzini wethu nasekuphileni kwethu, amabhethri e-lithium angabonwa yonke indawo.Kusukela kumakhalekhukhwini, ama-laptops namanye amadivaysi kagesi kuya ezimotweni zamandla amasha, amabhethri e-lithium-ion asetshenziswa ezimweni eziningi, ngevolumu encane, ukusebenza okuzinzile kanye nokujikeleza okungcono, ukusiza abantu ukusebenzisa kangcono amandla ahlanzekile.

Eminyakeni yamuva nje, i-China ibalwa phakathi kwabahamba phambili emhlabeni ocwaningweni nasekuthuthukisweni kwezobuchwepheshe okubalulekile, ukulungiswa kwezinto ezibonakalayo, ukukhiqizwa kwebhethri kanye nokusetshenziswa kwamabhethri e-sodium ion.

Inzuzo yokulondoloza inkulu

Njengamanje, ukuthuthukiswa kwesitoreji samandla e-electrochemical emelelwa amabhethri e-lithium-ion kuyakhula ngesivinini.Ibhethri ye-ion ye-lithium inamandla athile aphezulu, amandla athile, ukushaja nokukhipha ukusebenza kahle kanye ne-voltage ephumayo, nempilo ende yesevisi, ukuzikhipha okuncane, kuwubuchwepheshe obufanele bokugcina amandla.Njengoba izindleko zokukhiqiza ziwa, amabhethri e-lithium-ion afakwa kakhulu endaweni yokugcina amandla e-electrochemical, anomfutho oqinile wokukhula.

Ngokusho koMnyango Wezimboni Nobuchwepheshe Bolwazi, ngo-2022, amandla amasha okugcina amandla e-China akhuphuke ngo-200% unyaka nonyaka, futhi amaphrojekthi angaphezu kuka-20100 megawatt axhunywe kugridi, lapho isitoreji samandla ebhethri ye-lithium sabalelwa ku-97% umthamo omusha ofakiwe.

“Ubuchwepheshe bokugcina amandla buyisixhumanisi esibalulekile ekusebenziseni nasekuqaliseni uguquko olusha lwamandla.Ngaphansi kwesizinda sesu eliqondiswe kwikhabhoni embili, indawo yokugcina amandla entsha e-China ithuthuka ngokushesha.” USun Jinhua, isazi se-European Academy of Sciences kanye noprofesa we-University of Science and Technology yaseChina, ukusho ngokusobala ukuthi amandla amasha. isitoreji okwamanje sibonisa "i-lithium dominant" isimo.

Phakathi kobuchwepheshe obuningi bokugcina amandla e-electrochemical, amabhethri e-lithium-ion athathe isikhundla esiphezulu emishinini ye-elekthronikhi ephathekayo nezimoto zamandla amasha, akha uchungechunge lwezimboni oluphelele.Kodwa ngesikhathi esifanayo, ukushiyeka kwamabhethri e-lithium-ion kuye kwakhanga ukukhathazeka.

Ukushoda kwezinsiza kungenye yazo.Ochwepheshe bathi ukusatshalaliswa komhlaba wonke kwezinsiza ze-lithium akulingani ngokwedlulele, cishe ngamaphesenti angama-70 eNingizimu Melika, kanye namaphesenti ayisi-6 kuphela ezinsiza zomhlaba ze-lithium.

Ungathuthukisa kanjani ubuchwepheshe bebhethri bokugcina amandla aphansi obungancikile kuzinsiza ezingavamile?Ijubane lokuthuthukiswa kobuchwepheshe obusha bokugcina amandla obumelwe amabhethri e-sodium-ion liyakhula.

Ngokufana namabhethri e-lithium-ion, amabhethri e-sodium-ion ibhethri lesibili elithembele kuma-ion e-sodium ukuhamba phakathi kwama-electrode aqondile noma angalungile ukuze aqedele ukushaja nokukhipha umsebenzi.U-Li Jianlin, unobhala-jikelele weKomidi elijwayelekile lokugcina Amandla le-Chinese Electrotechnical Society, uthe emhlabeni wonke, izinqolobane zesodium ziningi kakhulu kune-lithium futhi zisakazwa kabanzi, kanti izindleko zamabhethri e-sodium ion ziphansi ngo-30-40% kune amabhethri e-lithium.Ngesikhathi esifanayo, amabhethri e-sodium ion anokuphepha okungcono nokusebenza okuphansi kwezinga lokushisa, kanye nokuphila komjikelezo ophezulu, okwenza amabhethri e-sodium ion abe umzila obalulekile wezobuchwepheshe ukuxazulula iphuzu lobuhlungu "lwe-lithium eyodwa kuphela".

Imboni inekusasa elihle

I-China ibheka ukubaluleka okukhulu ocwaningweni nasekuthuthukisweni nasekusetshenzisweni kwamabhethri e-sodium ion.Ngo-2022, i-China izofaka amabhethri e-sodium ion Ohlelweni Lweminyaka Eyi-14 Lweminyaka Emihlanu Yesayensi Nobuchwepheshe Okusha Emkhakheni Wamandla, futhi isekele ubuchwepheshe obusezingeni eliphezulu kanye nobuchwepheshe obuyisisekelo kanye nemishini yamabhethri e-sodium ion.NgoJanuwari 2023, ungqongqoshe neminye iminyango eyisithupha ngokuhlanganyela yakhipha “mayelana nokukhuthaza ukuthuthukiswa komhlahlandlela wemboni yezogesi kagesi”, ukuqinisa ucwaningo olusha lokugcinwa kwamandla ebhethri yezimboni, ucwaningo oluyimpumelelo yempilo ende yokuphepha okuphezulu kwesistimu yebhethri, umthamo omkhulu webhethri. ubuchwepheshe obusebenzayo bokhiye wokugcina amandla, usheshise ucwaningo nokuthuthukiswa kwamabhethri amasha njengebhethri ye-sodium ion.

U-Yu Qingjiao, unobhala-jikelele weZhongguancun New Battery Technology Innovation Alliance, uthe unyaka ka-2023 ubizwa ngokuthi “unyaka wokuqala wokukhiqizwa ngobuningi” kwamabhethri e-sodium embonini, futhi imakethe yebhethri ye-sodium yaseChina iyakhula.Esikhathini esizayo, emizuliswaneni emibili noma emithathu yezimoto zikagesi, isitoreji samandla sasekhaya, isitoreji samandla ezimbonini nezokuhweba, izimoto zamandla amasha nezinye izingxenye, ibhethri ye-sodium izoba isengezo esinamandla kumzila we-lithium webhethri yebhethri.

NgoJanuwari walo nyaka, uhlobo lwemoto entsha yaseChina i-JAC yttrium ilethe imoto yokuqala yebhethri ye-sodium emhlabeni.Ngo-2023, isizukulwane sokuqala samaseli ebhethri ye-sodium ion yethulwa okokuqala.Iseli lingashajwa ekamelweni lokushisa imizuzu engu-15 ekamelweni lokushisa, futhi amandla angafinyelela ngaphezu kwama-80%.Akukhona nje kuphela izindleko eziphansi, kodwa futhi uchungechunge lwezimboni luzozimela futhi luyalawuleka.

Ekupheleni konyaka odlule, iNational Energy Administration yamemezela iphrojekthi yokubonisa ukugcinwa kwamandla amasha.Ababili kwabaphumelele abangama-56 amabhethri e-sodium-ion.Ngokubona kukaWu Hui, umongameli we-China Battery Industry Research Institute, inqubo yokwenziwa kwezimboni yamabhethri e-sodium ion ikhula ngokushesha.Kulinganiselwa ukuthi ngo-2030, isidingo somhlaba wonke sokugcinwa kwamandla sizofinyelela cishe amahora angu-1.5 terawatt (Twh), futhi amabhethri e-sodium-ion kulindeleke ukuthi athole indawo yemakethe enkulu. , ukugcinwa kwamandla ekhaya kanye nokugcinwa kwamandla okuphathekayo, yonke imikhiqizo yokugcina amandla izosetshenziswa kabanzi kugesi we-sodium esikhathini esizayo. "Wu Hui uthe.

Umgwaqo Isicelo futhi eside

Njengamanje, ibhethri ye-sodium ion idonsela ukunaka emazweni ahlukahlukene.I-Nihon Keizai Shimbun ibike ukuthi kusukela ngo-December 2022, i-China yayinamaphesenti angaphezu kuka-50 engqikithi yamalungelo obunikazi asemthethweni emhlabeni wonke kumabhethri e-sodium ion, kuyilapho i-Japan, i-United States, iNingizimu Korea ne-France ikleliswe endaweni yesibili kuya kweyesihlanu.USun Jinhua uthe ngaphezu kokusheshisa okucacile kweShayina kokuthuthuka kwezobuchwepheshe kanye nokusebenzisa ngezinga elikhulu amabhethri e-sodium ion, amazwe amaningi ase-Europe nase-America nase-Asia aphinde afaka amabhethri e-sodium ion ohlelweni lokuthuthukisa amabhethri okugcina amandla.

U-Di Kansheng, isekela lomphathi jikelele we-Zhejiang Huzhou Guosheng New Energy Technology Co., LTD., uthe amabhethri e-sodium ion angafunda ohlelweni lokuthuthukiswa kwamabhethri e-lithium, athuthuke kusuka kumkhiqizo kuya kwezezimboni, anciphise izindleko, athuthukise ukusebenza, futhi akhuthaze izimo zokusetshenziswa. kuyo yonke imikhakha yempilo.Ngesikhathi esifanayo, ukuphepha kufanele kubekwe endaweni yokuqala, futhi izici zokusebenza zebhethri ye-sodium ion kufanele kudlalwe.

Naphezu kwesithembiso, ochwepheshe bathi amabhethri e-sodium ion asekude nesilinganiso sangempela.

U-Yu Puritan uthe ukuthuthukiswa kwamanje kwezimboni zebhethri le-sodium kubhekene nezinselelo ezifana nokushuba kwamandla aphansi, ubuchwepheshe obuzovuthwa, uchungechunge lokuhlinzeka ludinga ukuthuthukiswa, futhi izinga lezindleko eziphansi lethiyori alikafinyelelwa.Imboni yonke idinga ukugxila entweni emisha ehlanganyelwe ukukhuthaza imboni yebhethri yesodium ekuthuthukisweni kwemvelo kanye nezinga eliphezulu.(Intatheli uLiu Yao)
