Kuenzanisa kwezvakanaka uye zvisingabatsiri pakati pe lithium ion bhatiri uye sodium ion bhatiri.Mabhatiri eChina anonyanya kushandiswa mumaindasitiri matatu, anoti mota dzemagetsi, kuchengetedza simba uye zvemagetsi zvevatengi.Munharaunda idzi nhatu nzira, kunyanya mumakore achangopfuura, munda wemotokari dzemagetsi uye kuchengetedza simba rakagadzirwa nokukurumidza, rinotarisa mabhatiri e-lithium-ion.Kuenzaniswa ne lithium, sodium iriko zvakanyanya muzvisikwa uye iri nyore kuwana, asi yekutanga prototype yesodium ion bhatiri ine hunhu hwekuderera kuita uye hupenyu hupfupi.Ikozvino, sodium ion bhatiri yave nzira itsva inovimbisa.Ichi chinyorwa chinoongorora zvakanakira uye zvakaipira lithium-ion bhatiri uye sodium ion bhatiri.
Kushanda musimboti uye zvakanakira sodium ion bhatiri
Musimboti:mukugadzirisa uye kubudiswa, Na + yakavharidzirwa uye inobviswa shure uye mberi pakati pema electrode maviri: panguva yekuchaja, Na + inobviswa kubva kune electrode yakanaka uye yakaiswa mumagetsi asina kunaka kuburikidza ne electrolyte;Zvakapesana kana uchibvisa.
Zvakanakira:
(1) Zvigadzirwa zvesodium munyu zvakawanda uye zvakachipa.Kuenzaniswa neiyo ternary cathode zvinhu zve lithium-ion bhatiri, mutengo wezvakagadzirwa wakaderedzwa nehafu;
(2) Pamusana pemaitiro emunyu wesodium, inobvumirwa kushandisa low concentration electrolyte (ine yakafanana ye electrolyte, conductivity ye sodium munyu inenge 20% yakakwirira kupfuura ye lithium electrolyte) kuderedza mari;
(3) Sodium ions haigadziri alloy nealuminium.Aluminium foil inogona kushandiswa semuunganidzi weiyo yakaipa electrode, iyo inogona kuwedzera kuderedza mutengo neanenge 8% uye uremu neanenge 10%;
(4) Nekuda kwekubuda maitiro eiyo sodium ion bhatiri, hapana sodium ion discharge inobvumidzwa.Iyo simba density yesodium ion bhatiri yakakura kupfuura 100wh / kg, iyo inofananidzwa ne lithium iron phosphate bhatiri, asi mutengo wayo uri pachena, unotarisirwa kutsiva yechinyakare lead-asidhi bhatiri mune yakakura-chiyero chekuchengetedza simba.

Kuenzanisa kwezvakanaka uye zvisingabatsiri pakati pe lithium ion bhatiri uye sodium ion bhatiri
1. Vatakuri vemukati webheteri vakasiyana.Iyo lithium bhatiri inobhadharwa uye inobudiswa nekufamba uye kutendeuka kwe lithium ions pakati pezvakanaka uye zvisina kunaka electrodes, nepo sodium ion bhatiri inobhadharwa uye inobudiswa nekuiswa uye kubvisa ions sodium pakati pezvakanaka uye zvisina kunaka electrodes.Kutaura zvazviri, nheyo dzekushanda dzezviviri zvakafanana.
2. Nemhaka yekusiyana kweion radius, kushanda kwebhatiri ye-sodium ion yakaderera zvikuru kupfuura ye lithium ion battery;Iyo yakaipa electrode yelithium ion inogona kuita graphite, asi sodium ion haigone kuvharwa / kunyudzwa mugraphite, uye kugona kwacho kudiki kwazvo;Zvimwe zvinhu zvekabhoni zvinogona kusvika kusvika 300 MAH mushure mekurapwa;Iko kukwanisa kweion mu electrode yakanaka iduku zvikuru, inongopfuura 100 MAH;Kupokana kwesodium ion intercalation / de intercalation mune yakanaka uye yakaipa electrode yakakura kwazvo, iyo inobva kune yakakura radius;Kusadzoreka kudzoreredzwa uye hombe isingadzoreki kurasikirwa kwesimba.

Ikozvino mamiriro eiyo sodium ion bhatiri indasitiri muChina
Sodium ion bhatiri iindasitiri iri kusimukira.Inogona kuda kutsvagisa uye budiriro kuti itumbuke rose renguva.Parizvino, indasitiri yebhatiri yesodium iri kukurumidza muChina.Muna Ndira 2019, iyo sodium ion bhatiri yakazvimiririra yakagadziriswa neLiaoning XingKong sodium yemagetsi bhatiri Co., Ltd.Mutsetse wekutanga wesodium ion bhatiri wekugadzira bhatiri wakaiswa mukushanda, uye kukosha kwepagore kunotarisirwa kudarika bhiriyoni gumi yuan mushure mekugadzirwa kwakakura.
Kubva pakuona kweindasitiri, indasitiri yemabhatiri yesodium ichiri muhudiki.Mhedzisiro yakawanda yetsvakiridzo inongotenderedzwa mumakoreji nemayunivhesiti uye nemasangano ekutsvagisa, uye zvinotora nguva isati yanyatsoiswa mukuita - vamwe vaongorori vanototi hapana mukana weiyo sodium ion mabhatiri kudzamara matura eLithium epasi apera.Kufanana nehunyanzvi hwekunyepedzera tekinoroji, bhatiri yesodium inogona kusafarirwa pakutanga uye inogona kungotenderedzwa muchikoro chedzidzo, asi inogona kunge iine shanduko rimwe zuva uye nekukurumidza inogara muindasitiri.Izvi zvinogoneka, saka sodium bhatiri inonyatsokodzera kutariswa kwepamusoro kwevanotarisira kumberi mabhizinesi uye vanoisa mari.
Sodium ion bhatiri ndeimwe yeakakosha nzira yekusimudzira yesimba rekuchengetedza bhatiri mune ramangwana.Nekuenderera mberi kwekufambira mberi kweiyo sodium ion R & D tekinoroji, iyo yekushambadzira maitiro eiyo sodium ion mabhatiri acharamba achimhanyisa.Zvichida kurongeka kwendima iyi mberi kunotarisirwa kutungamira mumunda wemabhatiri emagetsi matsva.Ehe, zvinoita sekunge kare kare kutaura kuti sodium ion mabhatiri anotsiva lithium mabhatiri.
