Na libeteri tsa boemo bo tiileng li angoa ke serame?

hore na serame se ama libeteri tsa boemo bo tiileng joangle se etsoang ka hona:

Hobaneng serame e le phephetso

1. Ho tsamaisa motlakase ho tlase ha ionic

   • Li-electrolyte tse tiileng (liseramike, li-sulfide, li-polymer) li itšetlehile ka li-ion tsa lithium tse tlolang ka har'a meaho e thata ea kristale kapa ea polymer.

   • Maemong a mocheso o tlase, ho tlola hona hoa lieha, kahookhanyetso ea ka hare ea eketsehale ho fokotseha ha phepelo ea motlakase.

2. Mathata a sebopeho

   • Betri e nang le boemo bo tiileng, ho kopana ha electrolyte e tiileng le li-electrode ho bohlokoa.

   • Lithempereichara tse batang li ka fokotsa thepa ka lebelo le fapaneng, e leng se etsang horelikheo tse nyaneho li-interface → ho etsa hore phallo ea ion e mpefale.

3. Bothata ba ho tjhaja

   • Joalo ka libeteri tsa lithium-ion tse metsi, ho tjhaja mochesong o tlase haholo ho kotsiho penta ka lithium(lithium ea tšepe e thehoa holim'a anode).

   • Ha e le boemong bo tiileng, sena se ka ba kotsi le ho feta kaha li-dendrite (li-lithium tse kang linale) li ka petsola electrolyte e tiileng.

Ha e bapisoa le lithium-ion e tloaelehileng

• Li-electrolyte tse metsi tsa lithium-ion: Serame se etsa hore mokelikeli o be motenya (o se ke oa tsamaisa motlakase haholo), se fokotsa sebaka le lebelo la ho tjhaja.

• Lithium-ion ea boemo bo tiileng: Ho bolokehile haholo serameng (ha ho na ho hoama/ho dutla ha metsi), empae ntse e lahleheloa ke conductivityhobane lintho tse tiileng ha li tsamaise li-ion hantle mochesong o tlase.

Litharollo tsa hajoale lipatlisisong

1. Li-electrolyte tsa sulfide

   • Li-electrolyte tse ling tse tiileng tse thehiloeng ho sulfide li boloka phallo e phahameng ea motlakase esita le ka tlase ho 0 °C.

   • E tšepisa bakeng sa li-EV libakeng tse batang.

2. Mefuta e nyalisitsoeng ea polymer-ceramic

   • Ho kopanya li-polymer tse tenyetsehang le likaroloana tsa letsopa ho ntlafatsa phallo ea li-ion mochesong o tlase ha ka nako e ts'oanang ho boloka polokeho.

3. Boenjiniere ba sebopeho

   • Ho ntse ho ntshetswa pele dikoahelo kapa dikarolo tsa buffer ho boloka kgokelo ya electrode-electrolyte e tsitsitse nakong ya diphetoho tsa mocheso.

4. Mekhoa ea ho futhumatsa pele ho li-EV

   • Feela joalokaha li-EV tsa kajeno li futhumatsa libeteri tsa metsi pele li tjhaja, li-EV tsa boemo bo tiileng tsa nakong e tlang li ka sebelisataolo ea mochesoho boloka disele di le sebakeng sa tsona se loketseng (15–35 °C).

Kakaretso:
Libetri tsa boemo bo tiileng li hlile li angoa ke serame, haholo-holo ka lebaka la ho theoha ha motlakase oa li-ion le ho hanyetsa sebopeho. Li ntse li sireletsehile ho feta lithium-ion ea metsi maemong ao, empatshebetso (sebaka, sekgahla sa ho tjhaja, tlhahiso ya motlakase) e ka theoha haholo ka tlase ho 0 °CBafuputsi ba sebetsa ka mafolofolo ho li-electrolyte le meralo e lulang e tsamaisa motlakase serameng, ba ikemiselitse ho sebelisa ka mokhoa o tšepahalang ho li-EV esita le maemong a leholimo a mariha.
