Kini awọn batiri ion iṣuu soda ṣe?

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.
