QuantumScape: Takatanga kuyedza gumi-layer solids mune yekutengeserana fomati. Mabhatiri mushure memakore maviri kana kupfuura
QuantumScape, imwe yekutanga kushanda pane yakasimba electrolyte maseru, yakazvikudza nekutanga bvunzo ine gumi-layer maseru. Muna 10, kambani inoda kuratidza maseru ane gumi nemaviri akaturikidzana uye inoronga kuburitsa yekutanga bvunzo batch yakakodzera mota muna 2022.
Solid electrolyte masero anofanira kunge akasimba uye ane capacious. Vachiri kugara
Iwo maseru akagadzirwa neQuantumScape masisitimu Kunyangwe simbi isina anode... Iyo anode ine lithium pane electrode kana bhatiri rachajwa uye rinoparadzwa kana raburitswa. Mune sero re lithium-ion cell, anode inogadzirwa neimwe fomu yekabhoni (senge graphite), dzimwe nguva inoputirwa nesilicon. Kana muchitokisi musina graphite, haitore nzvimbo, saka huwandu hwehuremu hwesero uye huremu hunogona kushandiswa kuchengetedza charge.
QuantumScape yagara ichionekwa seyakanyanya kuvimbisa yekutanga kana zvasvika kune yakasimba-nyika maseru, asi kunyangwe iyi kambani inoti budiriro ichanonoka... Mushure meimwe- uye ina-masere masero, zvaive zvichikwanisika kugadzira 1-layer sero, iyo mumakumi ekutanga emakumi emakumi emakore ekushanda mu4C-10C modhi (kuchaja uye kuburitsa nesimba rakaenzana nesero kugona) uye C / 1-C / 1 modhi inoratidza kuderera kushoma. Asi aya angori 3-3 kutenderera kwemaseru mashoma, iyo kambani inotaura zvakananga nezvekutanga nhanho dzebasa:
Yekutanga miedzo yegumi-layer QuantumScape masero. Girafu inoratidza kuti chete 10-20 mitsetse (s) yeQuantumScape yakapedzwa.
Chakanakira kuyedza ndechekuti inoitwa pane tembiricha iri padyo nekamuri tembiricha (enzanisa: tembiricha yekushandisa ye eCitaro bhatiri kubva kuBlueSolutions). Uye kuti isu tiri kubata nemasero akakura muchimiro che 7,5 × 8 cm. Izvi zvakare kuwedzera mukana wekubatanidza iyo yakasimba QuantumScape electrolyte ine yakachipa lithium-iron-phosphate cathodes.... Chekupedzisira, mukana ndeyechinangwa cheQuantumScape, iyo inonyora ese akakodzera bvunzo paramita.
Chizvarwa chakapfuura chakasimba masero e electrolyte, 4-layer masero. Masero ainyanya kuita zvakanyanya akarasikirwa ne5-6 muzana yekugona kwavo mushure memazana mana ekushandiswa. Zvekufarira ndezviya zvinonyatsooneka pulsations yekuchinja kwesimba rekuburitsa (kureva, iyo bhatiri huwandu) pakarepo pamberi pekutenderera nhamba 400 (c) QuantumScape.
Asi ndiko kuguma kwezvikomborero. Lithium simbi masero anozvimba panguva yekushanda nekuti iyo yakambosungwa lithium inogadzira chinhu chakasiyana mavari - iyo anode. Saka QuantumScape inovaedza pa 3,4 atmospheres kuti inonoke maitiro. Izvi zvinoreva kuti depressurization inogona kuitika yebhatiri compartment inogona kutungamira mukutadza kwebhatiri mune ramangwana. Zvakafanana, hongu, nevhiri (puncture haina kunaka), asi tire haina kukosha kunyange 1/3 yemotokari.
Nekudaro, high tank pressure ingangove idiki yematambudziko. Zvakanaka, gumi-maseru maseru inhanho yepakati kana ichienzaniswa nemasero ane gumi nemaviri akaturikidzana, iyo yekupedzisira vhezheni inofanirwa muna 10. Ivo chete ndivo vanozopa yakakwana simba density kuti vakwanise kukwikwidza nekirasi lithium-ion maseru maererano nemutengo / kuita [QuantumScape haina kutaura]. Masero ekutanga emuenzaniso akakodzera kushandiswa kwemotokari achaonekwa paQS-2022 chirimwa muCalifornia muna 0, makore maviri kubva ikozvino, sezvo kambani parizvino iri kushanda kuwedzera kugadzirwa kwayo kweceramic separators (electrolytes).
Rigid 10-layer QuantumScape Cell (kuruboshwe) uye mutsara mutsva weannealing wakaiswa paQS-0 (c) QuantumSCape chirimwa
Iyo yakataurwa mukana wekushandisa iyo QuantumScape electrolyte muLFP maseru inotaridzika zvakanyanya kuvimbisa. Nekuda kweizvi, maseru akadaro anowana simba resimba re 0,6-0,7 kWh / l, rinoenderana neakanakisa emazuva ano lithium-ion masero ane nickel-manganese-cobalt cathodes uye mvura electrolytes. Munhu anotaura: neQuantumScape Porsche yakasimba electrolyte inogona kuchengetedza huwandu hwebhatiri reTaycan pasina kuwedzera saizi yemudziyo nekuderera kukuru kwemutengo wayo kuburikidza nekushandiswa kweLFP.
Iwo maseru haatarisirwe kutengeswa kusvika pakupera kwa2023 na2024.
Izvi zvinogona kukufadza:
