Cov roj teeb sodium ion ua los ntawm dab tsi?

Cov roj teeb sodium-ion yog ua los ntawm cov khoom siv zoo sib xws rau cov uas siv hauv cov roj teeb lithium-ion, tab sis nrogcov sodium (Na⁺) ionsua cov khoom nqa hluav taws xob es tsis yog lithium (Li⁺). Nov yog kev faib tawm ntawm lawv cov khoom ib txwm muaj:

1. Cathode (Electrode Zoo)

Qhov no yog qhov chaw uas cov sodium ions khaws cia thaum lub sijhawm tso tawm.

Cov ntaub ntawv cathode feem ntau:

• Sodium manganese oxide (NaMnO₂)

• Sodium hlau phosphate (NaFePO4)— zoo ib yam li LiFePO₄

• Sodium nickel manganese cobalt oxide (NaNMC)

• Prussian Xiav los yog Prussian Dawbcov khoom siv analogues - cov khoom siv pheej yig, them sai

2. Anode (Electrode Tsis Zoo)

Qhov no yog qhov chaw uas cov sodium ions khaws cia thaum lub sijhawm them.

Cov ntaub ntawv anode feem ntau:

• Cov pa roj carbon tawv- cov khoom siv anode feem ntau siv

• Cov hlau ua los ntawm Tin (Sn)

• Cov ntaub ntawv uas muaj phosphorus los yog antimony

• Cov oxides uas ua los ntawm titanium (piv txwv li, NaTi₂(PO₄)₃)

Lus Cim:Graphite, siv dav hauv cov roj teeb lithium-ion, tsis ua haujlwm zoo nrog sodium vim nws qhov loj me ionic loj dua.

3. Cov electrolyte

Cov khoom nruab nrab uas tso cai rau sodium ions txav mus los ntawm cathode thiab anode.

• Feem ntau ibntsev sodium(xws li NaPF₆, NaClO₄) yaj rau hauvcov kuab tshuaj organic(xws li ethylene carbonate (EC) thiab dimethyl carbonate (DMC))

• Qee cov qauv tsim tshiab sivcov electrolytes khov kho

4. Lub tshuab cais

Ib daim nyias nyias uas ua rau lub anode thiab cathode tsis txhob sib chwv tab sis tso cai rau ion ntws.

• Feem ntau yog ua los ntawmpolypropylene (PP) or polyethylene (PE)Cov Lus Qhia Txog Kev Txheeb Xyuas:

Qhia rau kuv paub yog tias koj xav tau kev sib piv ntawm cov roj teeb sodium-ion thiab lithium-ion.
