Vim li cas cov roj teeb sodium-ion zoo dua?

Sodium-ion roj teeb yog xamzoo dua lithium-ion roj teeb hauv txoj kev tshwj xeeb, tshwj xeeb tshaj yog rau cov kev siv loj thiab cov nqi-rhiab heev. Nov yogvim li cas cov roj teeb sodium-ion tuaj yeem ua tau zoo dua, nyob ntawm qhov kev siv:

1. Muaj ntau thiab tsawg-nqi raw khoom

• Sodiumyog 6th feem ntau cov khoom hauv ntiaj teb (los ntawm ntsev).

• Nws yogpheej yigthiabdav muajthoob ntiaj teb.

• Lithium, cobalt, thiab nickel siv hauv Li-ion roj teebscarcer thiab kim dua, nrog geopolitical thiab ib puag ncig kev txhawj xeeb nyob ib puag ncig lawv cov mining.

2. Kev cuam tshuam ib puag ncig qis

• Sodium-ion roj teebtsis xav tau cobalt lossis npib tsib xee, zam kev tsis ncaj ncees rau kev ua lag luam mining thiab txo kev puas tsuaj ib puag ncig.

• Yooj yim rau rov siv dua thiab tsis muaj pov tseg tsawg.

3. Txhim kho kev nyab xeeb

• Tsawg qhov kev pheej hmoo ntawm thermal runaway(hluav taws lossis tawg).

• Yuav siv taualuminium tam sim no collectorsntawm ob qho tib si electrodes, uas txhim kho kev ruaj ntseg thiab txo tus nqi ntxiv.

4. Kev ua tau zoo ntawm qhov kub thiab txias

• Na-ion roj teeb tuaj yeem ua tau zoo txawm tias nyob ntawm-20 ° C los yog txias dua, uas yog ib qho kev txwv rau ntau Li-ion chemistry.

5. Haum rau Loj-Scale Cia

• Zoo tagnrho raudaim phiaj zog cia, hnub ci thiab cua ua liaj ua teb, thiab cov txheej txheem thaub qab.

• Lub zog ceev tsis tseem ceeb hauv cov ntawv thov no, ua kom sodiumtus nqi thiab kev nyab xeeb muaj txiaj ntsig zoo dua.

6. Kev them nqi ceev ceev (txhim kho)

• Qee qhov niaj hnub sodium-ion chemistry pub rauceev ceev / tawm mus, uas yog qhov zoo rau lub zog cia thiab qee qhov kev thauj mus los.

Lawv nyob qhov twgTsis yogZoo dua

• Tsawg zog ceev(100–160 Wh/kg vs. Li-ion's 150–250+ Wh/kg).

• Heavier thiab bulkierrau tib lub zog.

• Muaj kev lag luam tsawg- tseem nyob rau theem pib ntawm kev tsim khoom loj.
