Na libeteri tsa boemo bo tiileng li angoa ke serame?

kamoo serame se amang dibetri tsa boemo bo tiilengle hore na ho etsoa eng ka eona:

Hobaneng ho bata e le phephetso

1. Ionic conductivity e tlase

   • Li-electrolyte tse tiileng (li-ceramics, sulfide, polymers) li itšetleha ka li-ion tsa lithium tse tlollang ka har'a kristale e thata kapa meaho ea polymer.

   • Ka lithemparetjha tse tlaase, hopping ena butle butle, kahoo theho hanyetsa ka hare ho eketsehale ho theoha ha phepelo ea motlakase.

2. Mathata a sefahleho

   • Ka betri ea boemo bo tiileng, ho bohlokoa ho kopana pakeng tsa electrolyte e tiileng le li-electrode.

   • Lithempereichara tse batang li ka fokotsa lisebelisoa ka litekanyetso tse fapaneng, ho thehalikheo tse nyanelibakeng tsa ho kopana → ho etsa hore ion e phalle le ho feta.

3. Bothata ba ho tjhaja

   • Joalo ka libetri tsa lithium-ion tsa metsi, ho tjhaja ka mocheso o tlase haholo ho kotsilithium plating(metallic lithium e etsa ka anode).

   • Boemong bo tiileng, sena se ka ba kotsi le ho feta kaha li-dendrites (li-lithium deposits tse kang nale) li ka senya electrolyte e tiileng.

Ha ho bapisoa le lithium-ion e tloaelehileng

• Mokelikeli oa electrolyte lithium-ion: Mohatsela o etsa hore mokelikeli o be motenya (o fokotsehe haholo), o fokotsa lebelo le lebelo la ho tjhaja.

• Boemo bo tiileng ba lithium-ion: Ho bolokehile ho bata (ha ho na metsi a leqhoa / a lutlang), empae ntse e lahleheloa ke conductivityhobane lintho tse tiileng ha li tsamaise li-ion hantle nakong ea mocheso o tlase.

Litharollo tsa hajoale lipatlisisong

1. Li-electrolyte tsa sulfide

   • Li-electrolyte tse ling tse thehiloeng ho sulfide li boloka boleng bo phahameng bo batlang bo le ka tlase ho 0 °C.

   • E ts'episa li-EV libakeng tse batang.

2. Mefuta e nyalisitsoeng ea polymer-ceramic

   • Ho kopanya li-polymers tse feto-fetohang le likaroloana tsa ceramic ho ntlafatsa phallo ea ion ka nako e tlaase ha u ntse u boloka tšireletso.

3. Boenjiniere ba li-interface

   • Ho ntse ho ntlafatsoa likhoele kapa li-buffer layers ho boloka khokahano ea electrode-electrolyte e tsitsitse ha mocheso o ntse o fetoha.

4. Sistimi ea ho futhumatsa pele ho li-EV

   • Joalo ka ha li-EV tsa kajeno li futhumatsa libeteri tsa metsi pele li tjhaja, li-EV tsa maemo a tlang li ka sebelisatsamaiso ea mochesoho boloka lisele li le maemong a tsona a loketseng (15-35 °C).

Kakaretso:
Libetri tsa boemo bo tiileng li hlile li angoa ke serame, haholo-holo ka lebaka la conductivity e tlase ea ion le khanyetso ea sebopeho. Li ntse li bolokehile ho feta mokelikeli oa lithium-ion maemong ao, empatshebetso (range, sekhahla sa tefiso, tlhahiso ea matla) e ka theoha haholo ka tlase ho 0 °C. Bafuputsi ba sebetsa ka mafolofolo ho li-electrolyte le meralo e lulang e le serame, e ikemiselitseng ho sebelisoa ka mokhoa o tšepahalang ho li-EV esita le maemong a leholimo a mariha.
