Mabhatiri emhando yepamusoro anokanganiswa nechando here?

kutonhora kunokanganisa sei mabhatiri e-solid-stateuye zviri kuitwa nezvazvo:

Sei kutonhora kuri dambudziko

1. Kuderedza kweionic conductivity

   • Ma electrolyte akaoma (ceramics, sulfides, polymers) anovimba nemaion e lithium anosvetuka-svetuka kuburikidza ne crystal kana polymer structures dzakasimba.

   • Pakupisa kwakaderera, kusvetuka uku kunononoka, sakakuramba kwemukati kunowedzerauye kudzikira kwesimba remagetsi.

2. Matambudziko ekushandisa painterface

   • Mubhatiri rine mamiriro akasimba, kubatana pakati peelectrolyte yakasimba nemaelectrode kwakakosha.

   • Kutonhora kunogona kuderedza zvinhu nematanho akasiyana, zvichiita kutimipata midikipa interfaces → zvichiita kuti kuyerera kwemaion kuwedzere kuipa.

3. Dambudziko rekuchaja

   • Kungofanana nemabhatiri e lithium-ion emvura, kuchaja patembiricha yakaderera zvikuru kune njodzikuputira lithium(simbi inonzi lithium inogadzirwa pa anode).

   • Kana zvaoma, izvi zvinogona kutokuvadza zvakanyanya sezvo dendrites (dzinoiswa mu lithium senge tsono) dzichigona kupwanya electrolyte yakasimba.

Zvichienzaniswa ne lithium-ion yenguva dzose

• Liquid electrolyte lithium-ion: Kutonhora kunoita kuti mvura yacho ikobvu (irege kufambisa mvura zvakanyanya), zvichideredza kukwirira kwayo uye kumhanya kwekuchaja.

• Lithium-ion ine mamiriro akasimba: Zvakachengeteka kana kuchitonhora (hapana mvura inotonhora/inodonhedza mvura), asiichiri kurasikirwa nekufambisa kwemheponekuti zvinhu zvakasimba hazvifambise maion zvakanaka pakupisa kwakaderera.

Mhinduro dziripo pari zvino dziri mukutsvaga

1. Ma electrolyte e sulfide

   • Mamwe ma electrolyte akasimba akavakirwa pa sulfide anochengetedza conductivity yakakwira kunyangwe iri pasi pe 0 °C.

   • Zvinovimbisa kutyaira mota dzemagetsi munzvimbo dzinotonhora.

2. Mahybridi ePolymer-ceramic

   • Kusanganisa mapolymer anochinjika nezvimedu zveceramic kunovandudza kufamba kwemaion pakupisa kwakaderera ukuwo kuchichengetedza kuchengetedzeka.

3. Uinjiniya hweinterface

   • Mapendi kana kuti mabuffer layers ari kugadzirwa kuti electrode-electrolyte contact irambe yakasimba panguva yekuchinja-chinja kwekushisa.

4. Masisitimu ekudziyisa magetsi mumotokari dzemagetsi

   • Kungofanana nemaEV emazuva ano anodziisa mabhatiri emvura asati achaja, maEV emazuva ano emagetsi anogona kushandisamanejimendi yekupisakuchengetedza masero ari munzvimbo yawo yakakodzera (15–35 °C).

Pfupiso:
Mabhatiri eSolid-state anokanganiswa nechando, kunyanya nekuda kwekudzikira kwe conductivity yemaion uye kusapindirana kweinterface. Achiri akachengeteka kupfuura liquid lithium-ion mumamiriro ezvinhu akadaro, asimashandiro (nzvimbo, mwero wekuchaja, simba rinobuda) zvinogona kudonha zvakanyanya pasi pe0 °CVaongorori vari kushanda nesimba pakugadzira maelectrolyte nemagadzirirwo anoramba achifambisa magetsi muchando, vachivavarira kushandiswa zvakavimbika mumagetsi emagetsi kunyangwe muchando.
