Kuyerekeza zabwino ndi zovuta pakati pa lithiamu ion batire ndi sodium ion batire.Mabatire aku China amagwiritsidwa ntchito makamaka m'mafakitale atatu, omwe ndi magalimoto amagetsi, kusungirako mphamvu komanso zamagetsi zamagetsi.Pafupi ndi njira zitatuzi, makamaka m'zaka zaposachedwa, gawo la magalimoto amagetsi ndi kusungirako mphamvu zamagetsi lakula mofulumira, likuyang'ana mabatire a lithiamu-ion.Poyerekeza ndi lithiamu, sodium ilipo kwambiri m'chilengedwe ndipo ndiyosavuta kupeza, koma mawonekedwe oyambirira a batri ya sodium ion ali ndi makhalidwe otsika komanso moyo waufupi.Tsopano, batire ya sodium ion yakhala njira yatsopano yodalirika.Nkhaniyi ikufotokoza ubwino ndi kuipa kwa batire ya lithiamu-ion ndi sodium ion batire.
Mfundo ntchito ndi ubwino wa sodium ion batire
Mfundo:poyendetsa ndi kutulutsa, Na + imayikidwa ndikuchotsedwa pakati pa ma electrode awiri: panthawi yolipiritsa, Na + imachotsedwa ku electrode yabwino ndikulowetsedwa mu electrode yolakwika kudzera mu electrolyte;Ndi zosiyana potulutsa.
Ubwino:
(1) Zida za mchere wa sodium ndizochuluka komanso zotsika mtengo.Poyerekeza ndi ternary cathode chuma lithiamu-ion batire, mtengo wa zipangizo yafupika ndi theka;
(2) Chifukwa cha makhalidwe a mchere wa sodium, amaloledwa kugwiritsa ntchito electrolyte yochepa (yomwe imakhala ndi electrolyte yofanana, kutsekemera kwa mchere wa sodium ndi pafupifupi 20% kuposa ya lithiamu electrolyte) kuchepetsa mtengo;
(3) Ma ion a sodium sapanga aloyi ndi aluminiyumu.Aluminiyamu zojambulazo angagwiritsidwe ntchito monga wokhometsa kwa elekitirodi zoipa, amene angathe kuchepetsa mtengo ndi pafupifupi 8% ndi kulemera pafupifupi 10%;
(4) Chifukwa cha kutulutsa kwa batri ya sodium ion, palibe kutulutsa kwa sodium ion kumaloledwa.Kachulukidwe mphamvu ya sodium ion batire ndi wamkulu kuposa 100wh / kg, amene angafanane ndi lithiamu chitsulo mankwala batire, koma mtengo wake phindu n'zoonekeratu, amene akuyembekezeka m'malo mwa chikhalidwe lead-asidi batire mu yaikulu yosungirako mphamvu.

Kuyerekeza zabwino ndi zovuta pakati pa lithiamu ion batire ndi sodium ion batire
1. Zonyamulira zamkati za batri ndizosiyana.Batire ya lithiamu imayimbidwa ndi kutulutsidwa ndi kayendedwe ndi kutembenuka kwa lithiamu ions pakati pa ma electrode abwino ndi oipa, pamene batri ya sodium ion imayimbidwa ndikutulutsidwa ndi kuyika ndi kuchotsedwa kwa ayoni a sodium pakati pa ma electrode abwino ndi oipa.Ndipotu, mfundo zogwirira ntchito ziwirizi ndizofanana.
2. Chifukwa cha kusiyana kwa ion radius, ntchito ya sodium ion batri ndi yotsika kwambiri kuposa ya lithiamu ion batri;Elekitirodi yoyipa ya lithiamu ion imatha kupanga graphite, koma ion ya sodium silingathe kuphatikizidwa / kuyikidwa mu graphite, ndipo mphamvu yake ndi yaying'ono kwambiri;Zida zina za carbon zimatha kufika pafupifupi 300 MAH pambuyo pa chithandizo;Mphamvu ya ayoni mu electrode yabwino ndi yaying'ono kwambiri, kuposa 100 MAH;Kukaniza kwa sodium ion intercalation / de intercalation mu ma elekitirodi abwino ndi oyipa ndiakulu kwambiri, omwe amachokera ku radius yayikulu;Kusintha kosasinthika komanso kutaya mphamvu kwakukulu kosasinthika.

Mkhalidwe wamakono wamakampani a sodium ion batire ku China
Batire ya sodium ion ndi bizinesi yomwe ikubwera.Zingafunike kufufuza zambiri ndi chitukuko kuti chiphuka nthawi.Pakadali pano, kutukuka kwa batire ya sodium kukukulirakulira ku China.Mu Januware 2019, batire ya sodium ion yomwe idapangidwa ndi Liaoning XingKong sodium electric battery Co., Ltd. ku Anshan posachedwapa idalowa mugawo lopanga zambiri.Mzere woyamba wapadziko lonse lapansi wopanga batire ya sodium ion udayamba kugwira ntchito, ndipo mtengo wapachaka ukuyembekezeka kupitilira 10 biliyoni pambuyo pakupanga kwakukulu.
Kuchokera pamalingaliro amakampani, kutukuka kwa mabatire a sodium akadali achichepere.Zotsatira zambiri za kafukufuku zimangofalitsidwa m'makoleji ndi mayunivesite ndi mabungwe ofufuza, ndipo zidzatenga nthawi kuti zigwiritsidwe ntchito - ofufuza ena amanena kuti palibe mwayi wa mabatire a sodium ion mpaka nkhokwe za lithiamu zatha.Monga luso laukadaulo wanzeru, batire la sodium silingayandidwe koyambirira ndipo limatha kufalitsidwa kokha kusukulu yamaphunziro, koma litha kukhala ndi kusintha tsiku lina ndikulowa mwachangu pamsika.Izi ndizotheka kwambiri, kotero batire ya sodium imayenera kuyang'aniridwa kwambiri ndi amalonda omwe akuyang'ana kutsogolo komanso osunga ndalama.
Batire ya sodium ion ndi imodzi mwamagawo ofunikira pakukulitsa batire yosungira mphamvu m'tsogolomu.Ndi kupita patsogolo kosalekeza kwaukadaulo wa sodium ion R & D, njira yogulitsira mabatire a sodium ion ipitilira kukwera.Mwinamwake masanjidwe a gawoli pasadakhale akuyembekezeka kutsogolera gawo la mabatire atsopano amphamvu.Zachidziwikire, zikuwoneka kuti ndizoyambirira kunena kuti mabatire a sodium ion m'malo mwa mabatire a lithiamu.
