Sodium-ion roj teeb tsim cov qauv thiab qhov zoo thiab qhov tsis zoo

Sodium-ion roj teeb raug cai

Sodium-ion batteries (SIBs luv luv) yog cov roj teeb uas muaj peev xwm rov qab tau uas muaj qhov zoo ntawm qhov muaj peev xwm, lub teeb yuag, tsis tshua muaj hluav taws xob, tsis tshua muaj hluav taws xob, thiab tus nqi qis. Cov cuab yeej tsim SIBs tuaj yeem hloov cov roj teeb Graphene lithium ib txwm siv yuav txhawb nqa tib neeg siv lub zog rov ua dua tshiab.

Feem ntau hais lus, kev ua haujlwm ntawm SIBs yog raws li hauv qab no: thaum them nyiaj / tso tawm, qhov concentration ntawm Na + ntawm cov electrodes ntawm SIBs nce / txo qis, thiab nrog rau kev siv cov khoom thauj thiab kev hloov pauv hauv lawv cov electrodes, them nyiaj oxidation / txo thaum kawg tsim hydrogen bonds. . Cov tshuaj tiv thaiv no tau ua tiav los ntawm ob lub thawv sib txawv ntawm lub tshuab hluav taws xob electrochemical. Ib lub thawv rov qab muaj Na + electrolyte, thiab lwm lub thawv ntawv muaj cov kua electrode.

Txhawm rau kom ua tau raws li qhov tam sim no muaj peev xwm thiab ntim cov khoom siv hluav taws xob, cov kws tshawb fawb nyiam siv cov electrodes nkhaus kom txo cov roj teeb loj ntawm SIBs. Piv nrog rau lwm hom roj teeb lithium-ion, nkhaus electrodes tuaj yeem hloov Na + ntawm ob lub ntim tau zoo dua. SIBs kuj tuaj yeem txhim kho rau hauv nano-copolymer electrodes, uas ua kom lub peev xwm siab thiab muaj peev xwm ua tau zoo ntawm lub roj teeb thaum lub sijhawm ua haujlwm raug.

20 pros thiab cons

qhov zoo:

1. Sodium-ion roj teeb muaj peev xwm ntau dua thiab tuaj yeem khaws ntau lub zog, ua rau lawv muaj peev xwm ua kom muaj peev xwm loj;

2. SIBs yog qhov me me thiab hnyav dua, uas tuaj yeem txuag qhov chaw thiab qhov hnyav;

3. Nws muaj qhov kub thiab txias tsis kam;

4. Me me tus nqi tso tawm, ntau lub zog ruaj khov;

5. SIBs muaj kev nyab xeeb zoo dua li lwm cov roj teeb thiab tsis tshua muaj hluav taws xob hauv cov kua polarization;

6. Nws muaj peev xwm rov ua dua tshiab thiab tuaj yeem rov qab siv tau ntau zaus;

7. SIBs muaj tus nqi qis thiab txuag cov nqi khoom hauv kev tsim khoom.

tsis txaus:

1. SIBs muaj qhov tsis tshua muaj hluav taws xob nyob rau hauv ib txwm muaj thiab tsis haum rau siv hauv cov ntawv thov hluav taws xob siab;

2. SIBs feem ntau muaj cov conductivity siab, uas ua rau cov nqi qis thiab kev ua haujlwm tawm;

3. Cov kev tiv thaiv sab hauv yog siab, thiab cov txheej txheem them nqi thiab kev tso tawm yuav ua rau poob zoo;

4. Cov khoom siv electrode tsis ruaj khov thiab tsis yooj yim rau kev tswj tau ntev;

5. Cov roj teeb qee zaum muaj qhov tsis ua haujlwm siab dua nyob rau hauv qhov kub thiab txias;

6. Lub peev xwm txo qis ntawm SIBs yuav ua rau poob ntau dua thaum lub caij ncig;

7. Tsis yog txhua yam khoom siv hluav taws xob tuaj yeem siv cov roj teeb sodium-ion. Piv txwv li, qee cov khoom siv yuav tsum muaj qee qhov input voltage ua ntej lawv tuaj yeem ua haujlwm tau zoo.
