Munguva ichangopfuura, China yekutanga yakakura-inokwana sodium-ion bhatiri simba rekuchengetedza simba chiteshi - Volin sodium-ion bhatiri rekuchengetedza simba chiteshi chaiswa muNanning, Guangxi. Iyi ndiyo yenyika yakakosha yekutsvakurudza uye chirongwa chekusimudzira "100 megawatt-awa sodium-ion bhatiri simba rekuchengetedza tekinoroji" chirongwa chekuratidzira chirongwa chechikamu chekutanga chepurojekiti, saizi yakaiswa ye2.5 megawatts / 10 megawatt-maawa.
Chiteshi chemagetsi chakaiswa mari uye chakavakwa neGuangxi Power Grid Kambani yeSouthern Power Grid, uye chiyero chechikamu ichi i10 MWh. Huyero hwese hwepurojekiti huchasvika zana MWh, iyo inogona kugadzira 73 miriyoni madhigirii emagetsi akachena gore rega, Chigadzirwa chemagetsi chinoiswa mari uye chinovakwa neGuangxi Power Grid Kambani yeSouthern Power Grid, uye chiyero chechikamu ichi 10 MWh. Huwandu hwepurojekiti iyi huchasvika pa100 MWh, iyo inogona kugadzira 73 miriyoni madhigirii emagetsi akachena gore rega, zvichideredza kuburitswa kwecarbon dioxide nematani zviuru makumi mashanu, uye kuzadzisa zvinodiwa nemagetsi zvevanoshandisa 35,000 pekugara.
Kuenzaniswa ne lithium-ion bhatiri rekuchengetedza simba, "hama" sodium-ion bhatiri simba rekuchengetedza raw material reserves, nyore kuburitsa, yakaderera mutengo, kuita zvirinani pakudziya kwakaderera, mune yakakura-mwero simba rekuchengetedza rine mabhenefiti ari pachena. "Sodium-ion bhatiri rekuchengetedza simba muchiyero chedanho rekusimudzira, mutengo wemutengo unogona kudzikiswa ne20% kusvika 30%, pasi pechinangwa chekuvandudza zvizere chimiro chebhatiri uye maitiro, kuvandudza chiyero chekushandiswa kwezvinhu uye kutenderera. hupenyu, mutengo wemagetsi unogona kuongororwa kusvika 0.2 yuan / kWh, ndeyekusimudzira kushandiswa kwehupfumi kwemhando itsva yekuchengetedza yenzira yakakosha yetekinoroji, "simba rekuchengetedza simba renyika Chen Man, mutevedzeri wemunyori mukuru weNational Electric. Simba Rekuchengetedza Tekinoroji Komiti uye yehunyanzvi-chikamu chehunyanzvi nyanzvi yeSouthern Power Grid, akadaro.
Kunyangwe basa reChina mukutsvagisa nekusimudzira, kugadzira, kumisa, kukwidziridzwa kwemusika uye kushandiswa kwezvigadzirwa zvemabhatiri e-sodium-ion kuri kutekeshera, hapana muenzaniso wepasirese wekushandiswa kweiyo sodium-ion bhatiri tekinoroji kune yakakura-simba rekuchengetedza simba zviteshi. .
Muna Mbudzi 2022, Guangxi Power Grid Kambani, yakabatana neSouth Grid Energy Storage Company, Institute of Physics yeChinese Academy of Sciences, Zhongkehai Sodium Technology Co., Ltd. nemamwe mayuniti echikwata cheprojekiti, yakatanga zviri pamutemo nyika. kiyi yekutsvagisa nekusimudzira chirongwa chepurojekiti sub-topic "100 megawatt-awa sodium-ion bhatiri rekuchengetedza simba system yekubatanidza tekinoroji uye application kuratidza" tsvagiridzo Tack the task. "Isu tinotarisa pane yakakwirira-inoshanda yemagetsi core scale kugadzirira, kubatanidzwa kwehurongwa nekudzivirira kuchengetedza uye kutonga uye mamwe matekinoroji akakosha ekuita tsvakiridzo, yakaumbwa neyakazvimiririra kodzero yepfuma yesodium-ion bhatiri kugadzirira uye system yekubatanidza tekinoroji," mutungamiri weprojekiti, iyo South China Grid Guangxi Grid Kambani, mutevedzeri wemukuru weDhipatimendi reInnovation Gao Lik akaunzwa.
Iyo yakakwirira-inokwana bhatiri sero ndiyo yakakosha unit yesodium-ion bhatiri simba rekuchengetedza system. Mushure megore nehafu yekutsvagisa, timu yeprojekiti yakagadzira yekutanga-yepasirebe-hupenyu, yakafara tembiricha zone, yakachengeteka yakakwirira 210Ah sodium-ion simba rekuchengetedza bhatiri. "Kubva pamaonero ekuita, rudzi rwedu rwesodium-ion bhatiri ine zvakanakira kushanda kwakakura tembiricha nzvimbo, kukurumidza kuchaja uye kuwanda kwakawanda, uye inogona kubhadhariswa kusvika 90% mumaminitsi gumi nemaviri," akadaro Hu Yongsheng, muongorori pa. Institute of Physics, Chinese Academy yeSainzi.
Sevanonyanya vatori vechikamu muchirongwa ichi, iyo SouthGrid Energy Storage Company Energy Storage Research Institute mu lithium bhatiri rekuchengetedza simba system yekubatanidza nekudzivirira kuchengetedza uye kutonga mumunda ine hupfumi hweruzivo rwekutsvagisa, ita iyo yenyika kiyi yekutsvagisa nekusimudzira chirongwa " lithium-ion bhatiri rekuchengetedza simba rehupenyu kutenderera kushandiswa kwekuchengetedza tekinoroji ”. "Kunyangwe maitiro ekuita kwemabhatiri esodium ne lithium akafanana, kuvandudzwa kwesimba rakakwana rekuchengetedza simba rinosanganisa kuchaja nekuburitsa hunhu hwemabhatiri esodium kunoda kukunda matambudziko mazhinji," akadaro Li Yongqi, nyanzvi yehunyanzvi kubva kuSouthGrid Energy Storage Company. , nemanzwiro.
Tichitora iyo yekubatanidza sisitimu semuenzaniso, timu yepurojekiti inotora dhizaini yakagoverwa yekuchengetedza simba zvichienderana neiyo yakakwira voltage yesodium-ion mabhatiri, uye iyo yese system inosanganisa makumi masere nemasere modular converter, ichiziva "imwe-kune-imwe tsamba" ne bhatiri masumbu, nepo yechinyakare yakagovaniswa dhizaini yelithium-ion simba rekuchengetedza sisitimu inongoda kubatanidza anopfuura makumi mana ekushandura. Chinangwa chekukurumidza chekupeta kaviri nhamba yevashanduri ndeyekuwedzera kukwanisa kuwanikwa uye simba rekushandura simba. Iyo yakazara simba rekushandura simba reiyi sodium bhatiri simba rekuchengetedza sisitimu inodarika 92%, nepo lithium mabhatiri kazhinji ari pasi pe90%, iyo inotarisirwa kuzadzisa uye zvinobudirira kutsiva lithium mabhatiri, uye kuiswa kune yakakura-yemagetsi magetsi ekuchengetedza simba, motokari dzemagetsi, michina yekuvaka nemimwe minda.
Kana zviri zvekudzivirira uye kutonga, timu yakagadzira nzira yekupisa yekudziya yemvura inotonhorera sisitimu pamwe neseti yakazara yekudzivirira moto uye kutonga matekinoroji eiyo sodium-ion bhatiri simba rekuchengetedza sisitimu, senge module-level thermal barriers uye. high-efficiency yekudzima moto.
Musiyano wetembiricha pakati peanopfuura 22,000 sodium bhatiri maseru mune yese system inodzorwa mukati me3 degrees Celsius. Kushandiswa kwezvose zvinopisa kupisa uye kupisa kwekupisa kwekudziviriragirazi fiber airgel gumbezesechinhu chinopisa chinodzivirira pakati pepakati pemagetsi, bhatiri monomer thermal runaway kupararira nguva kubva pamaminitsi makumi matatu kusvika kumaawa maviri, yakawedzerwa kusvika ku4 nguva, inovandudza zvikuru kuchengetedzwa kwebhatiri module.
Dare racho rakagadzira mvura nitrogen inobudirira moto inodzima, kutonhora, anti-reignition teknolojia, inokwanisa kudzima moto wekutanga webheteri mukati memasekondi e5, kuita maawa 24 pasina kupisa zvakare uye kuputika. "Irizvino lithium uye sodium simba rekuchengetedza tekinoroji kusimudzira kuvandudzwa kwehunhu hweumwe neumwe zviri pachena, iyi seti yesodium-ion bhatiri rekuchengetedza simba system yekutsvaga uye inoshanda mvura nitrogen inoshanda kudzima moto, kutonhora, anti-kutonga tekinoroji kuburikidza ne lithium-ion bhatiri simba. Kuchengetedza sisitimu yehupenyu kutenderera kushandiswa kwekuchengetedza tekinoroji shanduko yekushandisa mu lithium, sodium simba rekuchengetedza system kuwiriranisa kekutanga muinjiniya application, "LiYongQi akadaro.
Ndira 28, 2024, neChinese Academy of Engineering Jiang Jianchun academician, Chinese Academy of Sciences, Cheng Shijie academician, Zhang Yue academician, European Union Academy of Sciences Sun Jinhua academician nedzimwe nyanzvi dzeChina Machinery Industry Federation Appraisal Committee pa mhedzisiro yeprojekiti kuita wongororo yekuongorora: tekinoroji yese ye "10 MWh sodium ion bhatiri rekuchengetedza simba remagetsi emagetsi ekuchengetedza magetsi zviteshi" yakagadziriswa neboka reprojekiti iri padanho rinotungamira repasirese.
