Abatyeleli batyelela iimveliso zebhetri ye-sodium ion kwinkampani yaseTshayina kwi-Expo yokuqala ye-China ye-International Supply Chain Promotion Expo.Kumsebenzi wethu kunye nobomi bethu, iibhetri ze-lithium zinokubonwa kuyo yonke indawo.Ukusuka kwiifowuni eziphathwayo, iilaptops kunye nezinye izixhobo zombane ukuya kwizithuthi zamandla amatsha, iibhetri ze-lithium-ion zisetyenziswa kwiimeko ezininzi, ezinomthamo omncinci, ukusebenza okuzinzile kunye nokujikeleza okungcono, ukunceda abantu basebenzise amandla acocekileyo acocekileyo.

Kwiminyaka yakutshanje, i-China ibekwe phakathi kweyona ndawo iphezulu kwihlabathi kuphando oluphambili lwetekhnoloji kunye nophuhliso, ukulungiswa kwezinto eziphathekayo, ukuveliswa kwebhetri kunye nokusetyenziswa kweebhetri ze-sodium ion.

Inzuzo yokugcina inkulu

Okwangoku, ukuphuhliswa kokugcinwa kwamandla e-electrochemical emele iibhetri ze-lithium-ion zikhawuleza.Ibhetri ye-ion ye-lithium inamandla athile aphezulu, amandla athile, intlawulo kunye nokukhupha ukusebenza kakuhle kunye nombane ophumayo, kunye nobomi benkonzo ende, ukuzikhupha okuncinci, bubuchwephesha obufanelekileyo bokugcina amandla.Njengoko iindleko zokuvelisa ziwa, iibhetri ze-lithium-ion zifakwe kakhulu kwindawo yokugcina amandla e-electrochemical, kunye nokukhula okunamandla.

Ngokutsho koMphathiswa wezoShishino kunye neTekhnoloji yoLwazi, ngo-2022, amandla okugcina amandla amatsha eTshayina anyuke ngama-200% ngonyaka, kwaye iiprojekthi ezingaphezu kwama-20100 zeemegawatt zaye zadityaniswa kwigridi, apho ukugcinwa kwamandla ebhetri ye-lithium kubalelwa kwi-97% yombane. Umthamo omtsha ofakiweyo.

“Itekhnoloji yogcino lwamandla likhonkco eliphambili ekuphumezeni nasekuphumezeni utshintsho olutsha lwamandla.Phantsi kwemvelaphi yesicwangciso-qhinga sekhabhoni ephindwe kabini, ugcino lwamandla amatsha eTshayina lukhula ngokukhawuleza. ”USun Jinhua, isifundiswa seEuropean Academy of Sciences kunye nonjingalwazi weDyunivesithi yeSayensi kunye neTekhnoloji yaseTshayina, watsho ngokucacileyo ukuba amandla amatsha. ugcino ngoku lubonisa i” lithium dominant ” imeko.

Phakathi kobuninzi betekhnoloji yogcino lwamandla e-electrochemical, iibhetri ze-lithium-ion zibambe indawo ephambili kwisixhobo sombane esiphathwayo kunye nezithuthi zamandla amatsha, zenza umxokelelwane ogqibeleleyo woshishino.Kodwa kwangaxeshanye, ukusilela kweebhetri ze-lithium-ion kuye kwatsala inkxalabo.

Ukunqongophala kwezixhobo yenye yazo.Iingcali zithi ukuhanjiswa kwehlabathi kwezixhobo ze-lithium akulingani ngokugqithisileyo, malunga neepesenti ze-70 eMzantsi Melika, kunye neepesenti ezi-6 kuphela zezixhobo ze-lithium zehlabathi.

Indlela yokuphuhlisa iteknoloji yebhetri yokugcina amandla ephantsi engathembeli kwizinto ezinqabileyo?Isantya sokuphuculwa kweteknoloji entsha yokugcina amandla emele iibhetri zesodium-ion iyakhawuleza.

Ngokufana neebhetri ze-lithium-ion, iibhetri ze-sodium-ion ibhetri yesibini exhomekeke kwi-sodium ion ukuhamba phakathi kwe-electrodes efanelekileyo kunye ne-negative ukugqiba umrhumo kunye nokukhupha umsebenzi.U-Li Jianlin, unobhala jikelele we-Energy Standard Committee ye-Chinese Electrotechnical Society, uthe kwihlabathi jikelele, oovimba be-sodium bangaphezulu kakhulu kune-lithium kwaye basasazwa ngokubanzi, kwaye ixabiso leebhetri ze-sodium ion lingaphantsi kwe-30-40% kunelo iibhetri ze-lithium.Ngelo xesha, iibhetri ze-sodium ion zinokhuseleko olungcono kunye nokusebenza kweqondo lokushisa eliphantsi, kunye nobomi bomjikelezo ophezulu, okwenza iibhetri ze-sodium ion zibe yindlela ebalulekileyo yobugcisa ukuxazulula inqaku lentlungu "ye-lithium enye".

Ishishini linekamva elihle

I-China inamathela ngokubaluleka okukhulu kuphando kunye nophuhliso kunye nokusetyenziswa kweebhetri ze-sodium ion.Kwi-2022, i-China iya kubandakanya iibhetri ze-sodium ion kwi-14 yeSicwangciso seMinyaka emiHlanu yeSayensi kunye neTekhnoloji yoBuchule kwiNdawo yaMandla, kunye nokuxhasa iteknoloji yokusika kunye nobuchwepheshe obuphambili kunye nezixhobo zeebhetri ze-sodium ion.NgoJanuwari 2023, isebe kunye namanye amasebe amathandathu akhutshwe ngokudibeneyo "malunga nokukhuthaza uphuhliso lwesikhokelo sombane we-elektroniki", ukomeleza ugcino lwamandla olutsha lwebhetri yophando lwethekhnoloji yoshishino, inkqubo yophando lwenkqubo yebhetri yokhuseleko olude, ubungakanani obukhulu. iteknoloji esebenzayo yokugcina amandla engundoqo, ukukhawulezisa uphando kunye nophuhliso lweebhetri ezintsha ezifana nebhetri ye-sodium ion.

U-Yu Qingjiao, unobhala jikelele weZhongguancun New Battery Technology Innovation Alliance, uthe i-2023 ibizwa ngokuba "ngunyaka wokuqala wemveliso enkulu" yeebhetri zesodium kwishishini, kwaye imarike yebhetri yesodium yaseTshayina iyakhula.Kwixesha elizayo, kwimijikelo emibini okanye emithathu yezithuthi zombane, ukugcinwa kwamandla asekhaya, ukugcinwa kwamandla oshishino kunye nezorhwebo, izithuthi zamandla amatsha kunye namanye amacandelo, ibhetri ye-sodium iya kuba yongezelela ngamandla kwindlela ye-lithium ye-teknoloji yebhetri.

NgoJanuwari kulo nyaka, inqwelomoya entsha yaseTshayina i-JAC yttrium yazisa imoto yokuqala yehlabathi yebhetri yesodium.Ngo-2023, isizukulwana sokuqala seeseli zebhetri ye-sodium ion saqala ukusungulwa.Iseli inokuhlawuliswa kwiqondo lokushisa le-15 imizuzu kwiqondo lokushisa, kwaye amandla anokufikelela ngaphezu kwama-80%.Akunjalo kuphela iindleko eziphantsi, kodwa kunye nekhonkco lezoshishino liya kuzimela kwaye lilawuleke.

Ekupheleni konyaka odlulileyo, uLawulo lweSizwe lwezaMandla lubhengeze iprojekthi yokubonisa iprojekthi yokugcinwa kwamandla amatsha.Ababini kwabagqibeleleyo be-56 ziibhetri ze-sodium-ion.Kwimbono kaWu Hui, umongameli we-China Battery Industry Research Institute, inkqubo yoshishino lweebhetri ze-sodium ion ikhula ngokukhawuleza.Kuqikelelwa ukuba ngo-2030, imfuno yehlabathi yokugcina amandla iya kufikelela malunga ne-1.5 terawatt iiyure (Twh), kwaye iibhetri ze-sodium-ion kulindeleke ukuba zifumane indawo yentengiso enkulu. , ukugcinwa kwamandla ekhaya kunye nokugcinwa kwamandla aphathwayo, yonke imveliso yokugcina amandla iya kusetyenziswa ngokubanzi kumbane we-sodium kwixesha elizayo. "Wu Hui uthe.

Indlela yesicelo kunye nende

Okwangoku, ibhetri ye-sodium ion itsala ingqalelo kumazwe ahlukeneyo.I-Nihon Keizai Shimbun yabika ukuba ukususela ngoDisemba 2022, i-China yayingaphezu kwe-50 yeepesenti ze-patent ezisebenzayo zehlabathi kwiibhetri ze-ion ion, ngelixa i-Japan, i-United States, i-South Korea kunye ne-France ibeka indawo yesibini ukuya kweyesihlanu.USun Jinhua uthe ukongeza kwisantya esicacileyo saseTshayina sokuphumelela kwetekhnoloji kunye nosetyenziso olukhulu lweebhetri ze-sodium ion, amazwe amaninzi aseYurophu naseMelika naseAsia nawo afake iibhetri ze-ion yesodium kwinkqubo yophuhliso lwebhetri yokugcina amandla.

UDi Kansheng, usekela-mphathi jikelele weZhejiang Huzhou Guosheng New Energy Technology Co., LTD., Wathi iibhetri ze-sodium ion zinokufunda kwinkqubo yophuhliso lweebhetri ze-lithium, ukuphuhlisa ukusuka kwimveliso ukuya kumashishini, ukunciphisa iindleko, ukuphucula ukusebenza kunye nokukhuthaza iimeko zesicelo. kuzo zonke iinkalo zobomi.Ngelo xesha, ukhuseleko kufuneka lubekwe kwindawo yokuqala, kunye neempawu zokusebenza zebhetri ye-sodium ion kufuneka idlalwe.

Ngaphandle kwesithembiso, iingcali zithi iibhetri ze-sodium ion zisekude ukusuka kwisikali sokwenyani.

U-Yu Puritan uthe uphuhliso lwangoku loshishino lwebhetri yesodium lujongene nemingeni efana nokuxinana kwamandla aphantsi, itekhnoloji ukuba ikhule, ikhonkco lokubonelela kufuneka liphuculwe, kwaye inqanaba lexabiso eliphantsi lethiyori alikafikelelwa.Ishishini lonke kufuneka ligxininise kwi-innovation enzima yokubambisana ukukhuthaza imboni yebhetri ye-sodium kwi-ecological kunye nophuhliso lwezinga eliphezulu.
