Sodium-ion roj teeb cov roj teeb ntau lawm: los ntawm cov khoom siv raw rau cov hlwb tiav

Sodium-ion roj teeb (na-ion roj teeb) tau nyiam cov kev saib xyuas zoo li cov roj ntsha ua rau cov roj ntsha ntau thiab cov nqi qis ntawm cov khoom siv nplua nuj thiab cov nqi qis. Cov txheej txheem ntau lawm ntawm sodium-ion roj teeb qhia ntau yam sib xws nrog cov roj teeb lithium-ion vim muaj cov khoom siv tshwj xeeb ntawm cov khoom siv. Kab lus no qhia txog cov kauj ruam tseem ceeb hauv cov txheej txheem roj teeb ua lag luam.

Cathohoden Cov Ntaub Ntawv

Cov khoom siv cathoy rau cov roj teeb cov roj av muaj xws li NA3V 2} Cov ntaub ntawv no yog synthesized los ntawm cov tshuaj tiv thaiv-lub xeev, sol-gel cov txheej txheem, lossis cov txheej txheem los ntawm cov txheej txheem daus.

Cov Khoom Siv Anode

Cov pa roj carbon ua los ntawm biomass lossis suab yog qhov feem ntau dav siv anode cov khoom siv rau sodium-ion roj teeb. Lub hard cov pa roj carbon ua ntej yog carbonized thaum muaj kub (feem ntau {{}} ion degree) tsim nyog rau cov roj carbon-ion cia.

Electrolyte

Cov electrolyte feem ntau muaj cov ntsev ntsev (xws li Naclo4, NATFO4, NATFSI) yaj nyob rau hauv cov kuab tshuaj carbonate (EC, DMC, PC). Tau-lub xeev electrolytes, suav nrog Nasicon thiab Sulfide-tseem yog nyob rau hauv kev txhim kho.

Tus Separator

Polyethylene (PE) thiab polypropylene (PP) Separatorylene, tau siv rau cov roj teeb lithium-ion, txawm hais tias qhov sib xyaw ua ke nrog cov hluav taws xob nrog NA-ion nrog NA-ion electrolytes.

Kev Npaj Slurry Kev Npaj

Cov khoom siv nquag (cathode thiab anode), cov tshuaj ntxiv), thiab sbr) yog tov nrog cov kuab tshuaj (dej rau anode) los tsim cov khaub ncaws hnav zoo nkauj.

Daim plhaub

Lub slurry yog tusyees coated rau aluminium ntawv ci (cnure) thiab tooj liab ntawv ci (anode). Rau qee qhov sodium-ion roj teeb, ob lub electrodes yuav siv txhuas ntawv ci, nyob ntawm qhov rai voltage thiab cov khoom siv.

Kom qhuav

Cov coated electrodes yog qhuav hauv ncu kom tshem tawm cov kuab tshuaj uas tseem ceeb. Lub ziab kom qhuav thiab ntev yog ua tib zoo tswj kom tiv thaiv cov khoom siv.

Tom qab ziab, cov electrodes dhau los ntawm khub tuab, txhim kho qhov ceev, thiab ua kom pom kev zoo ntawm cov khoom siv nquag thiab cov neeg sau khoom tam sim no.

Cov electrodes yog txiav mus rau hauv cov duab uas xav tau (feem ntau cov duab plaub (feem ntau ntawm cov hnab ntim lossis cylindrical rau cylindrical cells). Qhov zoo electrode, cais tawm, thiab tsis zoo electrode yog pawg lossis qhov txhab mus rau hom xovtooj ntawm tes kawg.

Hnab Ntshav Hlwb

Cov cuab yeej hluav taws xob-cais cov khaubncaws sab nraud hluav taws xob yog ntim nrog cov hnab yas aluminium. Electrolyte tau txhaj rau hauv lub hnab, thiab lub hnab yog cua sov-sib khi los tiv thaiv kom to.

Cylindrical thiab prismatic hlwb

Lub qhov txhab electrode sib dhos yog muab tso rau hauv cov hlau tuaj yeem. Electrolyte yog ntxiv, ua raws los ntawm kev sib khi nrog lub hau.

Cov hlwb sib sau yauv ua ntej them cov txheej txheem, hu ua tsim. Kauj ruam no tso cai rau cov khoom siv hluav taws xob ruaj khov (sei) txheej rau daim ntawv ntawm anode nto, uas yog qhov tseem ceeb rau roj teeb ruaj khov. Tsim cov kev cai rau Sodium-ion roj teeb yuav txawv me ntsis los ntawm cov roj ntsha lithium-ion vim txawv foob.

Tom qab tsim, lub hlwb nyob sab laug rau hnub nyoog rau ob peb hnub los tswj lawv lub hauv kev chemistry. Txhua lub cell undergoes zoo tsim nyog tswj kev ntsuas, suav nrog cov tshev muaj peev xwm muaj peev xwm, kev kuaj pom kev nyuaj, thiab kev ntsuas kev nyab xeeb.

Kuaj cov hlwb tau sib sau ua ke rau hauv cov qauv thiab cov roj teeb. Kev tswj hwm cov roj teeb lub cev (BMS) yog sib xyaw ua ke rau saib xyuas cov hluav taws xob, ntsuas kub, thiab tam sim no kom ntseeg tau tias kev ua haujlwm zoo.

Cov txheej txheem ntau sidium-ion ntau dua cov txheej txheem Lithium-ion uas twb muaj lawm, ua rau nws yooj yim rau cov tuam ntxhab los txais yuav. Txawm li cas los xij, sodium-ion cov ntaub ntawv cov khoom sib txawv ntawm cov khoom sib txawv thiab cov khoom siv lub cev, xav tau qee yam kev hloov kho hauv slurry tsim, xaiv electrolyte, thiab tsim kev cai. Raws li Sodium-Ion Technology tseem ua kom paub tab ntxiv, nws cov khoom siv tus nqi thiab cov khoom siv nyoos muaj nyob hauv cov ntawv thov hluav taws xob loj.
