Vashanyi vanoshanyira sodium ion bhatiri zvigadzirwa kubva kuChina kambani paChina International International Supply Chain Promotion Expo.Mubasa redu uye hupenyu, mabhatiri e lithium anogona kuonekwa kwese kwese.Kubva panharembozha, malaptop uye zvimwe zvigadziriso zvemagetsi kumotokari dzemagetsi matsva, mabhatiri e-lithium-ion anoshandiswa muzviitiko zvakawanda, ane vhoriyamu shoma, kushanda kwakasimba uye kutenderera kuri nani, kubatsira vanhu kushandisa zviri nani simba rakachena.

Mumakore achangopfuura, China yakave pakati pepamusoro pasi rose mukutsvagisa nekusimudzira tekinoroji, kugadzirira zvinhu, kugadzirwa kwebhatiri uye kushandiswa kwemabhatiri ion ion.

Reserve advantage yakakura

Parizvino, kuvandudzwa kwe electrochemical energy kuchengetedza inomiririrwa ne lithium-ion mabhatiri ari kukurumidza.Lithium simba ion bhatiri ine yakakwira chaiyo simba, chaiyo simba, kuchaja uye kuburitsa zvakanaka uye kubuda magetsi, uye hupenyu hurefu hwesevhisi, kudiki kuzviburitsa, ndiyo yakakodzera kuchengetedza simba tekinoroji.Sezvo mutengo wekugadzira uchidonha, mabhatiri e-lithium-ion ari kuiswa zvakanyanya mumagetsi emagetsi ekuchengetedza, aine simba rekukura.

Sekureva kweBazi reMaindasitiri neRuzivo rweTekinoroji, muna 2022, simba idzva rekuchengetedza simba reChina rakawedzera ne200% gore negore, uye mapurojekiti anopfuura 20100 megawatt akabatanidzwa kune grid, iyo lithium bhatiri rekuchengetedza simba rakaita 97% ye huwandu hutsva hwakaiswa.

"Tekinoroji yekuchengetedza magetsi ndicho chinongedzo chakakosha mukuita nekuita shanduko itsva yesimba.Pasi pemaitiro maviri-kabhoni tarisiro, simba idzva rekuchengetera magetsi muChina riri kukura nekukurumidza. ”Sun Jinhua, mudzidzi weEuropean Academy of Sciences uye purofesa weUniversity of Science and Technology yeChina, akataura zvakajeka kuti simba idzva iri. chengetedzo parizvino iri kuratidza "lithium inotonga" mamiriro.

Pakati peakawanda emagetsi emagetsi ekuchengetedza tekinoroji, mabhatiri e-lithium-ion akagara pachinzvimbo chepamusoro mumidziyo yemagetsi inotakurika uye mota nyowani dzesimba, dzichigadzira cheni yakakwana yeindasitiri.Asi panguva imwecheteyo, kukanganisa kwemabhatiri e-lithium-ion kwakakwezvawo kunetseka.

Resource shomeka ndechimwe chazvo.Nyanzvi dzinoti kugovaniswa kwepasi rose kwerithium zviwanikwa hakuna kuenzana zvakanyanya, inosvika zvikamu makumi manomwe kubva muzana muSouth America, uye zvikamu zvitanhatu chete zvezviwanikwa zvelithium zvepasi.

Nzira yekugadzira yakaderera simba rekuchengetedza bhatiri tekinoroji isingavimbe nezviwanikwa zvisingawanzo?Iko kumhanya kwekusimudzira tekinoroji nyowani yekuchengetedza simba inomiririrwa nesodium-ion mabhatiri ari kukwidziridzwa.

Zvakafanana nemabhatiri e-lithium-ion, mabhatiri e-sodium-ion bhatiri rechipiri rinotsamira pamaioni e-sodium kuti afambe pakati pema electrode akanaka uye asina kunaka kuti apedze kuchaja uye kuburitsa basa.Li Jianlin, munyori mukuru weEnergy storage standard Committee yeChinese Electrotechnical Society, akataura kuti pasi rose, matura e sodium akawandisa kupfuura lithiamu uye akaparadzirwa zvakanyanya, uye mutengo wemabhatiri esodium ion wakaderera ne30-40% pane iwo lithium mabhatiri.Panguva imwecheteyo, mabhatiri e-sodium ion ane kuchengeteka zviri nani uye kuderera kwekushisa kwekushanda, uye hupenyu hwepamusoro-soro, izvo zvinoita kuti mabheti e-sodium ion ave nzira yakakosha yekugadzira kugadzirisa dambudziko re "lithium imwe chete".

Indasitiri ine ramangwana rakanaka

China inokoshesa kutsvagisa nekusimudzira uye kushandiswa kwemabhatiri e-sodium ion.Muna 2022, China ichasanganisira mabhatiri e-sodium ion muchirongwa chegumi nemana cheMakore mashanu eSainzi neTekinoroji Innovation muMunda weMagetsi, uye kutsigira tekinoroji yekucheka-kumucheto uye yakakosha tekinoroji uye zvishandiso zvesodium ion mabhatiri.Muna Ndira 2023, shumiro pamwe nemamwe madhipatimendi matanhatu akabatana "pamusoro pekusimudzira kuvandudzwa kwesimba remagetsi indasitiri kutungamira", kusimbisa hutsva hwekuchengetera simba bhatiri indasitiri yekutsvagisa tekinoroji, tsvakiridzo yehupenyu hurefu hwekuchengetedza bhatiri system, hombe-hombe. tekinoroji yakakosha yekuchengetedza simba, mhanyisa kutsvagisa nekuvandudza mabhatiri matsva senge sodium ion bhatiri.

Yu Qingjiao, munyori mukuru weZhongguancun New Battery Technology Innovation Alliance, akati 2023 inonzi "gore rekutanga rekugadzirwa kwakawanda" kwemabhatiri esodium muindastiri, uye musika weChina wesodium bhatiri uri kuwedzera.Mune ramangwana, mumatanho maviri kana matatu emotokari dzemagetsi, kuchengetedza simba repamba, maindasitiri uye ekutengesa simba rekuchengetedza, mota nyowani uye zvimwe zvikamu, sodium bhatiri ichava kuwedzera kune simba kune lithium bhatiri tekinoroji nzira.

Muna Ndira gore rino, mota nyowani yemagetsi yeChina JAC yttrium yakaunza mota yekutanga pasirese sodium bhatiri.Muna 2023, chizvarwa chekutanga chesodium ion bhatiri masero akatanga kutangwa.Iyo sero inogona kubhadhariswa pakamuri tembiricha kwemaminitsi gumi nemashanu pamhepo tembiricha, uye simba rinogona kusvika kupfuura 80%.Kwete chete mutengo wakaderera, asiwo maindasitiri ketani ichave yakazvimiririra uye inodzoreka.

Pakupera kwegore rapfuura, National Energy Administration yakazivisa chirongwa chekuratidzira chekuchengetedza simba idzva.Vaviri vevashanu vekupedzisira mabhatiri e-sodium-ion.Mukuona kwaWu Hui, purezidhendi weChina Battery Industry Research Institute, maitiro ekugadzirwa kwemabhatiri e-sodium ion ari kukura nokukurumidza.Zvinofungidzirwa kuti panosvika 2030, kudiwa kwepasi rose kwekuchengetedza simba kuchasvika pamaawa e1.5 terawatt (Twh), uye mabhatiri e-sodium-ion anotarisirwa kuwana nzvimbo yakakura yemusika. , kukuchengetedza simba repamba uye kuchengetedzwa kwesimba rinotakurika, zvigadzirwa zvese zvekuchengetedza simba zvichashandiswa zvakanyanya mumagetsi e sodium mune ramangwana. ”Wu Hui akadaro.

Nzira yekushandisa uye yakareba

Parizvino, sodium ion bhatiri inokwezva kutarisa kubva kune dzakasiyana nyika.Iyo Nihon Keizai Shimbun yakashuma kuti kubva muna Zvita 2022, China yaive inopfuura makumi mashanu muzana ezvese epasi rose patents mumabhatiri e-sodium ion, nepo Japan, United States, South Korea neFrance iri pachinzvimbo chechipiri kusvika chechishanu.Sun Jinhua yakataura kuti pamusoro pekukwira kweChina kwakajeka kwebudiriro yetekinoroji uye kushandiswa kwakakura kwemabhatiri e-sodium ion, nyika zhinji dzeEurope neAmerica neAsia dzakaisawo mabhatiri e-sodium ion mugadziriro yekusimudzira bhatiri.

Di Kansheng, mutevedzeri wemaneja mukuru weZhejiang Huzhou Guosheng New Energy Technology Co., LTD., Vakataura kuti mabhatiri e-sodium ion anogona kudzidza kubva mukuvandudza mabhatiri e-lithium, kukudziridza kubva pachigadzirwa kuenda kumaindasitiri, kuderedza mitengo, kuvandudza mashandiro, uye kukurudzira mamiriro ekushandisa. mumafambiro ose ehupenyu.Panguva imwecheteyo, kuchengetedzwa kunofanirwa kuiswa munzvimbo yekutanga, uye maitiro ekuita kweiyo sodium ion bhatiri inofanirwa kuridzwa.

Pasinei nechivimbiso, nyanzvi dzinoti mabhatiri e-sodium ion achiri kure kure nechiyero chaicho.

Yu Puritan akataura kuti ikozvino maindasitiri ekusimudzira bhatiri resodium akatarisana nematambudziko akadai sekushomeka kwesimba, tekinoroji kuti ive yakakura, ketani yekugovera inoda kuvandudzwa, uye theoretical yakaderera mutengo mwero hausati wasvika.Indasitiri yese inofanirwa kutarisisa pane yakaoma yekudyidzana innovation kusimudzira iyo sodium bhatiri indasitiri kune ecological uye yepamusoro nhanho budiriro.
