Awọn batiri Sodium-ion jẹ awọn ohun elo ti o jọra ni iṣẹ si awọn ti a lo ninu awọn batiri lithium-ion, ṣugbọn pẹluiṣuu soda (Na⁺) ionsbi awọn gbigbe idiyele dipo litiumu (Li⁺). Eyi ni pipinka ti awọn paati aṣoju wọn:
1. Cathode (Electrode to dara)
Eyi ni ibiti awọn ions iṣuu soda ti wa ni ipamọ lakoko idasilẹ.
Awọn ohun elo cathode ti o wọpọ:
-
Oxide soda manganese (NaMnO₂)
-
Sodium iron fosifeti (NaFePO₄)- iru si LiFePO₄
-
Sodium nickel manganese cobalt oxide (NaNMC)
-
Prussian Blue tabi Prussian Whiteawọn analogs - iye owo kekere, awọn ohun elo gbigba agbara-yara
2. Anode (Electrode Negetifu)
Eyi ni ibi ti awọn ions iṣuu soda ti wa ni ipamọ lakoko gbigba agbara.
Awọn ohun elo anode ti o wọpọ:
-
Erogba lile- awọn julọ o gbajumo ni lilo anode ohun elo
-
Tin (Sn) -orisun alloys
-
Phosphorus tabi awọn ohun elo ti o da lori antimony
-
Awọn ohun elo afẹfẹ ti o da lori Titanium (fun apẹẹrẹ, NaTi₂(PO₄)₃)
Akiyesi:Graphite, ni lilo pupọ ni awọn batiri lithium-ion, ko ṣiṣẹ daradara pẹlu iṣuu soda nitori iwọn ionic ti o tobi julọ.
3. Electrolyte
Alabọde ti o fun laaye awọn ions iṣuu soda lati gbe laarin cathode ati anode.
-
Ni igbagbogbo aiyọ iṣu soda(bii NaPF₆, NaClO₄) ni tituka ninu ẹyaOrganic epo(gẹgẹ bi awọn ethylene carbonate (EC) ati dimethyl carbonate (DMC))
-
Diẹ ninu awọn aṣa ti o nyoju lori to-ipinle electrolytes
4. Oluyapa
Membrane la kọja ti o tọju anode ati cathode lati fi ọwọ kan ṣugbọn ngbanilaaye sisan ion.

Maa ṣe tipolypropylene (PP) or polyethylene (PE)Tabili Lakotan:
Ẹya ara ẹrọ | Awọn apẹẹrẹ Ohun elo |
---|---|
Cathode | NaMnO₂, NaFePO₄, Prussian Blue |
Anode | Erogba lile, Tin, irawọ owurọ |
Electrolyte | NaPF₆ ni EC/DMC |
Oluyapa | Polypropylene tabi Polyethylene awo |
Jẹ ki n mọ ti o ba fẹ afiwe laarin iṣuu soda-ion ati awọn batiri lithium-ion.
