Libetri tsa sodium ion li entsoe ka eng?

Libetri tsa sodium-ion li entsoe ka thepa e ts'oanang le e sebelisoang ka libeteri tsa lithium-ion, empa kasodium (Na⁺) ionsjoalo ka bajari ba litefiso sebakeng sa lithium (Li⁺). Mona ke karohano ea likarolo tsa bona tse tloaelehileng:

1. Cathode (Positive Electrode)

Mona ke moo li-ion tsa sodium li bolokiloeng nakong ea ho tsoa.

Lisebelisoa tse tloaelehileng tsa cathode:

  • Sodium manganese oxide (NaMnO₂)

  • Sodium iron phosphate (NaFePO₄)- e tšoanang le LiFePO₄

  • Sodium nickel manganese cobalt oxide (NaNMC)

  • Boputsoa ba Prussia kapa Bosoeu ba Prussiali-analogues - thepa e theko e tlaase, e potlakisang ho tjhaja

2. Anode (Negative Electrode)

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

Lisebelisoa tse tloaelehileng tsa anode:

  • Khabone e thata- thepa ea anode e sebelisoang ka ho fetisisa

  • Li-alloys tse thehiloeng ho tin (Sn).

  • Phosphorus kapa thepa e thehiloeng ho antimone

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

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

3. Electrolyte

Mokhoa o lumellang li-ion tsa sodium ho tsamaea pakeng tsa cathode le anode.

  • Ka tloaelo aletsoai la sodium(joaloka NaPF₆, NaClO₄) e qhibilihisitsoeng kamotsoako oa motsoako(joalo ka ethylene carbonate (EC) le dimethyl carbonate (DMC))

  • Meetso e meng e hlahang e sebelisoali-electrolyte tse tiileng

4. Searohanyi

Lera la porous le thibelang anode le cathode hore le se ke la ama empa le lumella ho phalla ha ion.

  • Hangata e entsoe kapolypropylene (PP) or polyethylene (PE)Lethathamo la Kakaretso:

Karolo Mehlala ea Boitsebiso
Cathode NaMnO₂, NaFePO₄, Pula ea Prussia
Anode Khabone e thata, Tin, Phosphorus
Electrolyte NaPF₆ ho EC/DMC
Searohanyi Polypropylene kapa lera la polyethylene
 

Ntsebise haeba u batla papiso pakeng tsa libeteri tsa sodium-ion le lithium-ion.
