Simba uye bhatiri kuchengetedza

Iyo European project LISA yave kuda kutanga. Chinangwa chikuru: kusikwa kwe lithium-sarufa mabhatiri ane density ye 0,6 kWh / kg.

26.05.2022 /

Chaizvo musi waNdira 1, 2019, chirongwa cheEuropean LISA chinotanga, chinangwa chikuru chichave chiri kugadzirwa kweLi-S (lithium-sarufa) masero. Nekuda kwezvinhu zvesarufa, iyo yakareruka kupfuura simbi inoshandiswa nhasi, lithium sulfur masero anogona kusvika kune chaiyo simba re0,6 kWh / kg. Maseru akanakisa emazuva ano e-lithium-ion nhasi akatenderedza 0,25 kWh / kg.

Tafura yezvinyorwa

  • Lithium Sulfur Cells: Ramangwana reMota, Ndege uye Mabhasikoro
    • LISA project: high-density uye isingadhuri lithium-polymer mabhatiri ane yakasimba electrolyte.

Masayendisiti anoshanda pamasero emagetsi akaedza zvakanyanya lithium sulfur masero kwemakore mazhinji. Kugona kwavo kwakanaka nekuti vanovimbisa dzidziso chaiyo simba 2,6 kWh / kg (!). Panguva imwecheteyo, sarufa chinhu chakachipa uye chinowanikwa, nekuti imarara kubva kumagetsi anopfuta marasha.

Nhamo, sarufa zvakare ine drawback: zvisinei nekuti inovimbisa huremu hwakaderera hwemasero - ndosaka masero eLi-S akashandiswa mundege yemagetsi, achipwanya marekodhi endege asina kumira, physico-chemical properties inoita kuti ive chaiyo. inonyungudika nokukurumidza mu electrolyte... Nemamwe mashoko: Bhatiri reLi-S rinokwanisa kuchengetedza chaji yakakura pachiyero cheyuniti, asi panguva yekushanda inoparadzwa zvisingadzoreki..

> Bhatiri reRivian rinoshandisa masero 21700 - seTesla Model 3, asi pamwe LG Chem.

LISA project: high-density uye isingadhuri lithium-polymer mabhatiri ane yakasimba electrolyte.

Iyo LISA (lithium sulfur yemagetsi akachengeteka mumigwagwa) chirongwa chinotarisirwa kutora makore anopfuura 3,5. Yakapihwa mari pamwe chete muhuwandu hwe7,9 miriyoni euros, iyo yakaenzana nemamiriyoni makumi matatu nemana emazlotys. Inopindwa neOxis Energy, Renault, Varta Micro Battery, Fraunhofer Institute uye Dresden University of Technology.

Iyo LISA purojekiti ine chinangwa chekugadzira Li-S maseru ane asingabatike akasimba mahybrid electrolyte. Izvo zvinodiwa kugadzirisa dambudziko rekudzivirira ma electrodes, izvo zvinotungamirira kukurumidza kuparara kwemasero. Masayendisiti anoti kubva kune theoretical simba density ye2,6 kWh / kg, chokwadi 0,6 kWh / kg inogona kuwanikwa.

> Asphalt (!) Ichawedzera huwandu uye nekukurumidza kuchaja kwe lithium-ion mabhatiri.

Kana yaive pedyo chaizvo nenhamba iyi, ine huremu hwemazana akati wandei makirogiramu Mabhatiri emotokari dzemagetsi anodonha kubva kune akati wandei (!) Kusvika ku200 kilogiramu.... Ichi chinogona kunge chiri chipikiri mubhokisi remahydrogen cell mota (FCEVs), sezvo matangi eToyota Mirai ehydrogen ega anorema 90 kg.

Iyo purojekiti ichagadziridzwa pasi pesimba reOxis Energy (mabviro). Iyo kambani inoti yakatokwanisa kugadzira maseru ane simba re 0,425 kWh / kg anogona kushandiswa mundege. Nekudaro, hupenyu hwavo uye kuramba kutenderera-kuburitsa-kutenderera hazvizivikanwe.

> Li-S mabhatiri - shanduko mundege, midhudhudhu uye mota

Izvi zvinogona kukufadza:
