Lub roj teeb sodium ion ua haujlwm li cas?

A sodium-ion roj teeb (Na-ion roj teeb)ua haujlwm zoo ib yam li lub roj teeb lithium-ion, tab sis nws sivsodium ions (Na⁺)tsis yogLithium ions (Li⁺)khaws cia thiab tso tawm lub zog.

Ntawm no yog ib qho yooj yim tawg ntawm nws ua haujlwm li cas:

---

Basic Components:

1. Anode (tsis zoo electrode)- Feem ntau ua los ntawm cov roj carbon tawv lossis lwm yam khoom siv uas tuaj yeem tuav cov sodium ions.
2. Cathode (zoo electrode)- Feem ntau ua los ntawm sodium-muaj hlau oxide (xws li sodium manganese oxide lossis sodium hlau phosphate).
3. Electrolyte- Cov kua los yog khoom nruab nrab uas tso cai rau sodium ions txav ntawm cov anode thiab cathode.
4. Separator- Ib daim nyias nyias uas tiv thaiv kev sib cuag ncaj qha ntawm anode thiab cathode tab sis tso cai rau ions dhau mus.

Nws ua haujlwm li cas:

Thaum them nyiaj:

1. Sodium ions txavlos ntawm cathode mus rau anodelos ntawm electrolyte.
2. Electrons ntws los ntawm sab nraud Circuit Court (charger) mus rau anode.
3. Sodium ions khaws cia (intercalated) hauv cov khoom siv anode.

Thaum tshem tawm:

1. Sodium ions txavlos ntawm anode rov qab mus rau cathodelos ntawm electrolyte.
2. Electrons ntws los ntawm sab nraud Circuit Court (powering ib tug ntaus ntawv) los ntawm anode mus cathode.
3. Lub zog raug tso tawm kom muaj zog rau koj lub cuab yeej.

Cov ntsiab lus tseem ceeb:

• Lub zog cia thiab tso tawmtso siab raurov qab mus rau sab nraud ntawm sodium ionsnruab nrab ntawm ob lub electrodes.
• Cov txheej txheem yogthim rov qab, tso cai rau ntau lub sijhawm them nqi / tso tawm.

Pros ntawm Sodium-Ion roj teeb:

• pheej yig duaraw cov ntaub ntawv (sodium yog ntau).
• Muaj kev nyab xeeb duanyob rau hauv tej yam mob (tsawg reactive tshaj lithium).
• Kev ua tau zoo dua hauv qhov txias txias(rau qee cov chemistry).

Cons:

• Tsawg zog ceev piv rau lithium-ion (tsawg zog khaws cia ib kg).
• Tam sim notsis paub tabtechnology-cov khoom lag luam tsawg dua.
