Libetri tsa sodium ion li entsoe ka eng?

Libetri tsa sodium-ion li entsoe ka thepa e tšoanang ka ts'ebetso le tse sebelisoang libetering tsa lithium-ion, empa li na leli-ion tsa sodium (Na⁺)e le lijari tsa ho tjhaja ho ena le lithium (Li⁺). Mona ke tlhaloso ya dikarolo tsa tsona tse tlwaelehileng:

1. Cathode (Electrode e Ntle)

Mona ke moo li-ion tsa sodium li bolokoang teng nakong ea ho ntša metsi.

Lisebelisoa tse tloaelehileng tsa cathode:

• Sodium manganese oxide (NaMnO₂)

• Phosphate ea tšepe ea sodium (NaFePO₄)— e tšoanang le LiFePO₄

• Sodium nickel manganese cobalt oxide (NaNMC)

• Putsoa ea Prussia kapa Bosweu ba Prussiali-analog — thepa e theko e tlase, e tjhajang ka potlako

2. Anode (Electrode e mpe)

Mona ke moo li-ion tsa sodium li bolokoang teng nakong ea ho tjhaja.

Lisebelisoa tse tloaelehileng tsa anode:

• Khabone e thata— thepa ea anode e sebelisoang haholo

• Li-alloy tse thehiloeng ho tin (Sn)

• Lisebelisoa tse thehiloeng ho phosphorus kapa antimoni

• Li-oxide tse thehiloeng ho titanium (mohlala, NaTi₂(PO₄)₃)

Hlokomela:Graphite, e sebelisoang haholo libetering tsa lithium-ion, ha e sebetse hantle le sodium ka lebaka la boholo ba eona bo boholo ba ionic.

3. Electrolyte

Sesebediswa se dumellang di-ion tsa sodium ho tsamaya pakeng tsa cathode le anode.

• Ka tloaelo aletsoai la sodium(joalo ka NaPF₆, NaClO₄) e qhibilihisitsoeng ka har'atharollo ea lintho tse phelang(joalo ka ethylene carbonate (EC) le dimethyl carbonate (DMC))

• Meralo e meng e hlahang e sebelisali-electrolyte tsa boemo bo tiileng

4. Sekarohano

Lera le nang le masoba le thibelang anode le cathode ho ama empa le dumella phallo ya ion.

• Hangata e entsoe kapolypropylene (PP) or politheine (PE)Tafole ea Kakaretso:

Mpolelle haeba o batla papiso pakeng tsa libeteri tsa sodium-ion le lithium-ion.
