Mfundo yopangira batire ya sodium-ion

Mabatire a sodium-ion (SIBs mwachidule) ndi mabatire osungira mphamvu omwe amatha kuwonjezeredwa omwe ali ndi ubwino wokhala ndi mphamvu zambiri, kulemera kwake, kutulutsa kutentha kochepa, kutsika pang'ono, komanso kutsika mtengo. Chipangizo chopangidwa ndi ma SIBs chingalowe m'malo mwa mabatire achikhalidwe a Graphene lithiamu adzalimbikitsa mwamphamvu kugwiritsa ntchito mphamvu kwa anthu.

Nthawi zambiri, mfundo yogwirira ntchito ya ma SIBs ndi awa: pakulipiritsa/kutulutsa, kuchuluka kwa Na+ pa ma elekitirodi a SIBs kumawonjezeka/kuchepa, ndipo pogwiritsa ntchito katundu ndi kusintha kwa maelekitirodi awo, kutsitsa oxidation / kuchepetsa pamapeto pake kumapanga ma hydrogen bond. . Zochita izi zimamalizidwa ndi zotengera ziwiri zotsutsana za cell electrochemical. Chidebe chimodzi chotsutsana chili ndi Na+ electrolyte, ndipo chidebe china chotsutsana nacho chili ndi madzi a electrode.

Pofuna kukwaniritsa kuchuluka kwa zinthu zamakono komanso kuchuluka kwa zinthu zamagetsi, ofufuza amakonda kugwiritsa ntchito ma elekitirodi opindika kuti achepetse kukula kwa batri la ma SIB. Poyerekeza ndi mitundu ina ya batri ya lithiamu-ion, maelekitirodi okhotakhota amatha kusamutsa Na + pakati pa zida ziwiri bwino kwambiri. Ma SIB amathanso kusinthidwa kukhala ma elekitirodi a nano-copolymer, omwe amawonetsetsa kuti batire ili ndi mphamvu zambiri komanso magwiridwe antchito nthawi zonse panthawi yolondola.

20 zabwino ndi zoyipa

ubwino:

1. Mabatire a sodium-ion ali ndi mphamvu zambiri ndipo amatha kusunga mphamvu zambiri, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito mphamvu zazikulu;

2. Ma SIB ndi ang'onoang'ono kukula kwake komanso opepuka, omwe amatha kusunga malo ndi kulemera kwake;

3. Ali ndi kutentha kwabwino komanso kukhazikika kwa kutentha;

4. Mlingo wodzitulutsa pang'ono, kusungirako mphamvu zolimba;

5. Ma SIB ali ndi chitetezo chabwino kuposa mabatire ena ndipo sangathe kuyatsa polarization yamadzimadzi;

6. Ili ndi luso lobwezeretsanso ndipo imatha kugwiritsidwanso ntchito nthawi zambiri;

7. Ma SIB ali ndi mtengo wotsika ndipo amasunga ndalama zakuthupi popanga.

zoperewera:

1. Ma SIB ali ndi magetsi otsika pansi pazikhalidwe zabwinobwino ndipo sali oyenera kugwiritsidwa ntchito pamagetsi apamwamba;

2. Ma SIB nthawi zambiri amakhala ndi ma conductivity apamwamba, zomwe zimapangitsa kuti pakhale mtengo wotsika komanso kutulutsa bwino;

3. Kukaniza kwamkati kumakhala kwakukulu, ndipo njira zolipiritsa ndi kutulutsa zidzabweretsa kutaya kwakukulu;

4. Zinthu za elekitirodi ndizosakhazikika komanso zovuta kuzisunga kwa nthawi yayitali;

5. Mabatire nthawi zina amakhala ndi chiwongola dzanja chachikulu pansi pa kutentha kwakukulu ndi mikhalidwe yovuta;

6. Kuchepa kwa mphamvu za SIBs kudzasokoneza kwambiri panthawi yozungulira;

7. Sizinthu zonse zamagetsi zomwe zingagwiritse ntchito mabatire a sodium-ion. Mwachitsanzo, zipangizo zina zimafunika kusunga mphamvu yamagetsi inayake kuti zigwire ntchito bwino.
