Munguva pfupi yapfuura, chiteshi chemagetsi chekuchengetedza simba chemabhatiri e sodium-ion chikuru muChina - Volin sodium-ion battery energy storage station chakatanga kushanda muNanning, Guangxi. Ichi ndicho chirongwa chenyika chekutsvaga nekusimudzira "100 megawatt-hour sodium-ion battery energy storage technology" chirongwa chekuratidzira chirongwa chekutanga chechirongwa ichi, saizi yakaiswa ye2.5 megawatts/10 megawatt-hours.
Chiteshi chemagetsi ichi chakaiswa mari uye chakavakwa neGuangxi Power Grid Company yeSouthern Power Grid, uye chiyero chechikamu chino i10 MWh. Huwandu hwese hweprojekiti huchasvika 100 MWh, iyo inogona kugadzira madhigirii emagetsi akachena anosvika mamiriyoni makumi manomwe nematatu pagore. Chiteshi chemagetsi chinoiswa mari uye chakavakwa neGuangxi Power Grid Company yeSouthern Power Grid, uye chiyero chechikamu chino i10 MWh. Huwandu hwese hweprojekiti huchasvika 100 MWh, iyo inogona kugadzira madhigirii emagetsi akachena anosvika mamiriyoni makumi manomwe nematatu pagore, zvichideredzawo kuburitswa kwecarbon dioxide nematani zviuru makumi mashanu, uye kusangana nezvinodiwa zvemagetsi zvevanhu 35,000 vanogara mudzimba.
Zvichienzaniswa nekuchengetwa kwesimba rebhatiri re lithium-ion, "hama" dzinochengetedza simba rebhatiri re sodium-ion, zviri nyore kubvisa, mutengo wakaderera, kushanda zviri nani pakupisa kwakaderera, mukuchengetedza simba kwakakura kune zvakanakira zviri pachena. "Kuchengetwa kwesimba rebhatiri re sodium-ion muhukuru hwedanho rekuvandudza, mutengo wemutengo unogona kuderedzwa ne20% kusvika 30%, pasi pepfungwa yekuvandudza zvizere chimiro chebhatiri uye maitiro, kuvandudza mwero wekushandiswa kwezvinhu uye hupenyu hwedenderedzwa, mutengo wemagetsi unogona kuongororwa kusvika ku0.2 yuan / kWh, ndeyekusimudzira kushandiswa kwehupfumi kwemhando itsva yekuchengetera yenzira yakakosha yetekinoroji," akadaro Chen Man, mutevedzeri wemunyori mukuru weNational Electric Power Storage Technical Committee uye nyanzvi yehunyanzvi yeSouthern Power Grid.
Kunyange hazvo basa reChina mukutsvaga nekugadzira, kugadzira, kugadzirisa mamiriro ekunze, kusimudzira musika uye kushandisa zvigadzirwa zvemabhatiri e sodium-ion riri kufamba zvakanaka, hapana muenzaniso wepasi rose wekushandiswa kwetekinoroji yemabhatiri e sodium-ion kunzvimbo dzemagetsi dzinochengetera simba guru.
Muna Mbudzi 2022, Guangxi Power Grid Company, pamwe chete neSouth Grid Energy Storage Company, Institute of Physics of the Chinese Academy of Sciences, Zhongkehai Sodium Technology Co., Ltd. nedzimwe nzvimbo dzechikwata cheprojekiti, vakatanga zviri pamutemo chirongwa chechirongwa chekutsvaga nekusimudzira chirongwa chenyika chinonzi "100 megawatt-hour sodium-ion battery energy storage system integration technology and application demonstration" tsvakurudzo. "Tinotarisa pakugadzirira kwepakati pemagetsi epamusoro-soro, kubatanidzwa kwesystem nekudzivirira nekudzora kuchengetedzeka uye mamwe matekinoroji akakosha ekuita tsvakiridzo, akaumbwa nekodzero dzepfungwa dzekugadzira bhatiri resodium-ion nesystem integration technology," mutungamiri weprojekiti, South China Grid Guangxi Grid Company, mutevedzeri wemukuru weDhipatimendi reInnovation Gao Lik akazivisa.
Sero rebhatiri rine simba guru ndiro chinhu chikuru chehurongwa hwese hwekuchengetedza simba rebhatiri re sodium-ion. Mushure megore rimwe nehafu rekutsvaga, timu yepurojekiti yakagadzira bhatiri rekutanga pasi rose rinogara kwenguva refu, nzvimbo yakafara yekupisa, nzvimbo yakachengeteka ye 210Ah sodium-ion. "Kubva pakuona kwekushanda, mhando yedu yebhatiri re sodium-ion ine zvakanakira nzvimbo yakafara yekushanda, kuchaja nekukurumidza uye kuwanda kwakanaka, uye inogona kuchajwa kusvika 90% mumaminitsi gumi nemaviri," akadaro Hu Yongsheng, muongorori paInstitute of Physics, Chinese Academy of Sciences.
Sevatori vechikamu vakuru vehunyanzvi muchirongwa ichi, SouthGrid Energy Storage Company Energy Storage Research Institute mukubatanidzwa kwe lithium battery energy storage system uye kudzivirira nekudzora kuchengetedzeka mumunda uyu ine ruzivo rwakakura rwekutsvagisa, inoita chirongwa chenyika chekutsvaga nekusimudzira "lithium-ion battery energy storage system lifecycle application of safety technology". "Kunyangwe misimboti yekuita kwemabhatiri e sodium ne lithium yakafanana, kugadzirwa kwesystem yakakwana yekuchengetedza simba inosanganisa hunhu hwekuchaja nekuburitsa mabhetiri e sodium kunoda kukunda matambudziko mazhinji matsva," akadaro Li Yongqi, nyanzvi yehunyanzvi kubva kuSouthGrid Energy Storage Company, nemanzwiro.
Tichitora semuenzaniso wekubatanidzwa kwesystem, timu yepurojekiti iyi inoshandisa nzira itsva yekuchengetera simba yakagoverwa zvichibva pamagetsi akawanda emabhatiri e sodium-ion, uye system yese inobatanidza ma modular converters 88, zvichiita kuti "kuwirirana kwemunhu mumwe nemumwe" nemabhatiri, nepo dhizaini yechinyakare ye lithium-ion energy storage system ichingoda kubatanidza ma converters anopfuura 40. Chinangwa chekuwedzera kaviri huwandu hwema converters ndechekuwedzera kuwanikwa kwesimba uye kushanda zvakanaka kwesimba. Kushanda zvakanaka kwesimba re sodium battery energy storage system iyi kunopfuura 92%, nepo mabhatiri e lithium anowanzova pasi pe90%, izvo zvinotarisirwa kuti zvizadzikise uye zvibudirire mabhatiri e lithium, uye zvinoshandiswa pakuchengetera simba re electrochemical, mota dzemagetsi, michina yekuvaka nedzimwe nzvimbo.
Nezvekudzivirira nekudzora kuchengetedzeka, timu iyi yakagadzira nzira yekutarisira kupisa kwemvura inotonhodza pamwe chete netekinoroji yakakwana yekudzivirira nekudzora moto ye sodium-ion battery energy storage system, yakaita se module-level thermal barrier uye high-efficiency fire extinguishes.
Musiyano wetembiricha uripo pakati pemasero ebhatiri re sodium anopfuura 22,000 muhurongwa hwese unodzorwa mukati me3 degrees Celsius. Kushandiswa kwese ...gumbeze regirazi re airgelSechinhu chinodzivirira kupisa pakati pepakati pemagetsi, nguva yekupararira kwemonomer yebhatiri inodziya kubva pamaminitsi makumi matatu kusvika maawa maviri, yakawedzerwa kusvika ka4, zvichivandudza zvikuru kuchengetedzeka kwemodule yebhatiri.
Chikwata chakagadzira tekinoroji yekudzimisa moto inoshanda nenitrogen, kutonhora, uye inodzivirira kudzima, inokwanisa kudzima moto wekutanga webhatiri mukati memasekonzi mashanu, kuti iite maawa makumi maviri nemana isina kubatidzazve kana kuputika. "Tekinoroji yemazuva ano yekuchengetedza simba re lithium ne sodium yekusimudzira kuvandudzwa kwehunhu hweumwe neumwe zviri pachena, iyi seti yekutsvagisa sisitimu yekuchengetedza simba rebhatiri re sodium-ion uye tekinoroji inoshanda yekudzimisa moto inoshanda ne nitrogen, kutonhora, inodzivirira kudzima kuburikidza ne lithium-ion battery energy storage system lifecycle application yekushandura tekinoroji yekuchengetedza mu lithium, sodium energy storage system synchronization kekutanga mu engineering application," akadaro LiYongQi.
