Alendo amayendera mabatire a sodium ion kuchokera ku kampani yaku China pachiwonetsero choyamba cha China International Supply Chain Promotion Expo.Mu ntchito yathu ndi moyo, mabatire a lithiamu amatha kuwoneka kulikonse.Kuchokera ku mafoni a m'manja, ma laputopu ndi zipangizo zina zamagetsi kupita ku magalimoto atsopano amagetsi, mabatire a lithiamu-ion amagwiritsidwa ntchito pazochitika zambiri, ndi voliyumu yaying'ono, ntchito yokhazikika komanso kuyendayenda bwino, kuthandiza anthu kugwiritsa ntchito bwino mphamvu zoyera.

M'zaka zaposachedwa, China yakhala pampando wapamwamba kwambiri padziko lonse lapansi pakufufuza ndi chitukuko chaukadaulo, kukonzekera zinthu, kupanga batire komanso kugwiritsa ntchito mabatire a sodium ion.

Reserve mwayi waukulu

Pakali pano, chitukuko cha electrochemical mphamvu yosungirako oimiridwa ndi lithiamu-ion mabatire ikupita patsogolo.Lithium energy ion batire ili ndi mphamvu zenizeni zenizeni, mphamvu zenizeni, kuwongolera ndi kutulutsa mphamvu komanso voteji yotulutsa, komanso moyo wautali wautumiki, kudzitsitsa pang'ono, ndiukadaulo wosungira mphamvu.Pamene ndalama zopangira zimatsika, mabatire a lithiamu-ion akuyikidwa kwambiri m'malo osungira magetsi a electrochemical, ndi kukula kwakukulu.

Malinga ndi Unduna wa Zamakampani ndi Zaukadaulo Zaukadaulo, mu 2022, mphamvu yaku China yosungirako mphamvu yatsopano idakula ndi 200% chaka chilichonse, ndipo ma projekiti opitilira 20100 megawatt adalumikizidwa ndi gridi, pomwe kusungirako mphamvu ya batire ya lithiamu ndi 97% ya kuchuluka kwatsopano komwe kunayikidwa.

“Tekinoloje yosungiramo mphamvu ndi njira yofunika kwambiri pakukhazikitsa ndi kukhazikitsa njira yatsopano yosinthira mphamvu.Pansi pa njira yopangira mpweya wapawiri, malo osungiramo magetsi atsopano ku China akukula mwachangu. ”Sun Jinhua, wophunzira wa European Academy of Sciences komanso pulofesa wa University of Science and Technology ya China, adanena momveka bwino kuti mphamvu zatsopano yosungirako panopa akusonyeza "lifiyamu lalikulu" mkhalidwe.

Pakati pa matekinoloje ambiri osungira mphamvu zamagetsi, mabatire a lithiamu-ion atenga malo otsogola pazida zam'manja zamagetsi ndi magalimoto amagetsi atsopano, ndikupanga unyolo wathunthu wamafakitale.Koma nthawi yomweyo, zofooka za mabatire a lithiamu-ion zakopanso nkhawa.

Kusowa kwa zinthu ndi chimodzi mwa izo.Akatswiri amati kugawa padziko lonse kwa zinthu za lithiamu sikuli kofanana kwambiri, pafupifupi 70 peresenti ku South America, ndi 6 peresenti yokha yazinthu zadziko lapansi za lithiamu.

Momwe mungakhazikitsire ukadaulo wa batri wosungira mphamvu zochepa zomwe sizidalira zinthu zachilendo?Liwiro la kukweza kwa matekinoloje atsopano osungira mphamvu omwe akuimiridwa ndi mabatire a sodium-ion akukulitsidwa.

Mofanana ndi mabatire a lithiamu-ion, mabatire a sodium-ion ndi batire yachiwiri yomwe imadalira ayoni a sodium kuti asunthe pakati pa ma electrode abwino ndi oipa kuti amalize kulipira ndi kutulutsa ntchito.Li Jianlin, mlembi wamkulu wa Energy Storage Standard Committee of the Chinese Electrotechnical Society, adanena kuti padziko lonse lapansi, nkhokwe za sodium ndizochulukirapo kuposa lithiamu ndipo zimafalitsidwa kwambiri, ndipo mtengo wa mabatire a sodium ion ndi 30-40% wotsika kuposa wa. mabatire a lithiamu.Panthawi imodzimodziyo, mabatire a sodium ion amakhala ndi chitetezo chabwino komanso kutentha kwapansi, komanso moyo wozungulira kwambiri, zomwe zimapangitsa kuti mabatire a sodium ion akhale njira yofunikira kwambiri yothetsera ululu wa "lithiyamu imodzi yokha".

Makampaniwa ali ndi tsogolo labwino

China imawona kufunikira kwakukulu pakufufuza ndi chitukuko ndi kugwiritsa ntchito mabatire a sodium ion.Mu 2022, China idzaphatikizapo mabatire a sodium ion mu 14th Five-year Plan for Science and Technology Innovation in the Field of Energy, ndikuthandizira ukadaulo wamakono ndi ukadaulo wapakatikati ndi zida zamabatire a sodium ion.Mu Januwale 2023, unduna ndi m'madipatimenti ena asanu ndi limodzi anapereka pamodzi "za kulimbikitsa chitukuko cha mphamvu zamagetsi makampani malangizo", kulimbikitsa latsopano mphamvu yosungirako batire mafakitale kafukufuku sayansi, kafukufuku wojambula wapamwamba moyo wautali chitetezo batire dongosolo, lalikulu-kulu mphamvu yaikulu. ukadaulo wofunikira wosungira mphamvu, kufulumizitsa kafukufuku ndi chitukuko cha mabatire atsopano monga batri ya sodium ion.

Yu Qingjiao, mlembi wamkulu wa Zhongguancun New Battery Technology Innovation Alliance, adati chaka cha 2023 chimatchedwa "chaka choyamba chopanga" mabatire a sodium pamakampani, ndipo msika waku China wa batire ya sodium ukukulirakulira.M'tsogolomu, muzitsulo ziwiri kapena zitatu zamagalimoto amagetsi, kusungirako mphamvu zapakhomo, kusungirako mphamvu za mafakitale ndi zamalonda, magalimoto atsopano amphamvu ndi magawo ena, batire ya sodium idzakhala yowonjezera yamphamvu ku njira ya teknoloji ya lithiamu.

Mu Januware chaka chino, galimoto yatsopano yamagetsi yaku China ya JAC yttrium idapereka galimoto yoyamba padziko lonse lapansi ya batri ya sodium.Mu 2023, m'badwo woyamba wa ma cell a batri a sodium ion adayambitsidwa.Selo likhoza kuimbidwa pa kutentha kwa mphindi 15 kutentha kwa firiji, ndipo mphamvu imatha kufika kupitirira 80%.Sikuti mtengo wake ndi wotsika, komanso unyolo wa mafakitale udzakhala wodziyimira pawokha komanso wowongolera.

Kumapeto kwa chaka chatha, National Energy Administration idalengeza projekiti yoyeserera yosungira mphamvu zatsopano.Awiri mwa omaliza 56 ndi mabatire a sodium-ion.Malinga ndi Wu Hui, pulezidenti wa China Battery Industry Research Institute, njira yopangira mafakitale a mabatire a sodium ion ikukula mofulumira.Akuti pofika chaka cha 2030, kufunika kosungirako mphamvu padziko lonse kudzafika pafupifupi maola 1.5 a terawatt (Twh), ndipo mabatire a sodium-ion akuyembekezeka kupeza msika waukulu. , kusungirako magetsi kunyumba ndi kusungirako magetsi, zinthu zonse zosungiramo mphamvu zidzagwiritsidwa ntchito kwambiri mumagetsi a sodium mtsogolomu. "Wu Hui adatero.

Njira yofunsira komanso yayitali

Pakalipano, batire ya ion sodium imakopa chidwi cha mayiko osiyanasiyana.Nyuzipepala ya Nihon Keizai Shimbun inanena kuti pofika mu December 2022, dziko la China linali ndi zoposa 50 peresenti ya ma patent ovomerezeka padziko lonse m'mabatire a sodium ion, pamene Japan, United States, South Korea ndi France zinakhala zachiwiri mpaka zisanu.Sun Jinhua adanena kuti kuwonjezera pa kupititsa patsogolo kwaukadaulo kwa China komanso kugwiritsa ntchito kwambiri mabatire a sodium ion, mayiko ambiri aku Europe ndi America ndi Asia aphatikizanso mabatire a sodium ion munjira yopangira batire yosungira mphamvu.

Di Kansheng, wachiwiri kwa manejala wamkulu wa Zhejiang Huzhou Guosheng New Energy Technology Co., LTD., adati mabatire a ayoni a sodium angaphunzire kuchokera pakupanga mabatire a lithiamu, kukula kuchokera kuzinthu kupita kumakampani, kuchepetsa ndalama, kukonza magwiridwe antchito, komanso kulimbikitsa zochitika zogwiritsa ntchito. m'mbali zonse za moyo.Nthawi yomweyo, chitetezo chiyenera kuyikidwa pamalo oyamba, ndipo mawonekedwe a batire a sodium ion ayenera kuseweredwa.

Ngakhale lonjezoli, akatswiri amati mabatire a sodium ion akadali kutali ndi sikelo yeniyeni.

Yu Puritan adanena kuti chitukuko chamakono cha batri ya sodium chikukumana ndi zovuta monga kuchepa kwa mphamvu zamagetsi, teknoloji kuti ikhale yokhwima, njira zothandizira ziyenera kukonzedwa, ndipo mtengo wotsika mtengo sunafikebe.Makampani onse akuyenera kuyang'ana kwambiri zovuta zogwirira ntchito kuti zilimbikitse bizinesi ya batri ya sodium kuti ipititse patsogolo chitukuko cha chilengedwe komanso chapamwamba.
