Zinjani izinhlayiya ze-electrode ezintsha? 

Izinhlayiya ze-Electrode: Izinhlayiya ezibanzi ze-PoindeleElectrode ziyizakhi ezibalulekile kumadivayisi ahlukahlukene we-electrochemical, okuthinta kakhulu ukusebenza kanye nesikhathi sokuphila. Lo mhlahlandlela uhlola izici zawo, izinhlobo, izinhlelo zokusebenza, kanye nokucatshangelwa kokukhethwa.

Ukuqonda izinhlayiya ze-electrode

Yini izinhlayiya ze-electrode?

Izinhlayiya ze-Electrode yizinto ezisetshenziswayo microscopic ezisetshenziselwa ukwakha ama-electrodes kumabhethri, amaseli kaphethiloli, ama-supercapacitors, nezinye izinhlelo ze-electrochemical. Banikeza indawo enkulu engaphezulu yokusabela kwe-electrochemical ukwenzeka, kuthonya ukusebenza kahle kanye nobuningi bamandla bedivayisi. Izakhiwo zalezi zinhlayiya, njengosayizi, i-morphology kanye nokwakheka, ziyinto ebucayi Ukunquma ukusebenza kwensiza. Ukukhethwa kwe Izinhlayiya ze-Electrode Kuya ngokwanele kuhlelo lokusebenza oluthile nezimpawu ezifiselekayo.

Izinhlobo zezinhlayiya ze-electrode

Izinto ezahlukahlukene ziqashiwe njenge Izinhlayiya ze-Electrode, ngasinye sinezinzuzo ezihlukile nobunzima. Izinhlobo ezijwayelekile zifaka: I-Metal Oxides: njengeLicoo2, I-Limn2O4, neLifepo4, esetshenziswe kabanzi kumabhethri e-lithium-ion ngenxa yobuningi bawo bamandla aphezulu. Izinto zekhabhoni: kufaka phakathi i-graphite, i-carbon ecushiwe eyenziwe ngekhabhoni, ne-carbon nanotubes, ebaluleke kakhulu ekusebenzeni kukagesi kanye nokusebenza kwezindleko. Lokhu kuvame ukusetshenziswa kumabhethri e-lithium-ion kanye nama-supercapacitors. I-Metal Sulfides: Isibonelo, i-Mos2 ne-FES2, enikeza amakhono aphezulu wethiyori kodwa angahlushwa impilo emnandi yokujikeleza. Ukuqhuba ama-polymers: njenge-polyaniline ne-polyyrrole, eyaziwa ngokuguquguquka kwazo kanye namandla okuqina kwamandla aphezulu, kepha kuvame ukukhombisa ukwenziwa okuphansi kunezinye izinto.

Izici ezithinta ukusebenza kwezinhlayiya ze-electrode

Izinto eziningana zithonya kakhulu ukusebenza kwe Izinhlayiya ze-Electrode:

Ubukhulu bezinhlayiyana ne-morphology

Usayizi nokwakheka kwe Izinhlayiya ze-Electrode thinta ngqo indawo engaphezulu etholakalayo yokuphendula kwe-electrochemical. Izihlanzi ezincane ngokuvamile zihlinzeka ngezindawo ezinkulu zomhlaba, eziholela ekuthuthukiseni amanani. Kodwa-ke, izinhlayiya ezincane kakhulu zingaholela ekuhlanganiseni okukhuphukayo futhi kunciphise ukuqina. I-morphology, noma ukwakheka, nayo idlala indima; Isibonelo, izinhlayiya ze-porous zingashukumisa ukuthuthukisa ukungena kwe-electrolyte nokuhamba kwe-ion.

Ukwakheka Kwezinto Ezibonakalayo

Ukwakheka kwamakhemikhali kwe Izinhlayiya ze-Electrode Ibizela izakhiwo zazo ze-electrochemical, njenge-voltage yazo, umthamo, kanye nokuphila komjikelezo. Ukukhethwa ngokucophelela kwezinto zokwakha kubalulekile ukuze wenze kahle ukusebenza kwedivayisi. Isibonelo, ukukhetha phakathi kweLood2, iLiMN2O4, neLifePo4 kumabhethri e-lithium-ion kufaka phakathi ukuhweba phakathi kobuningi bamandla, izindleko, nokuphepha.

Ukuhlanganiswa komhlaba kanye nokuguqulwa

Ukuguqulwa komhlaba, njengezimbobo noma i-doping, kungathuthukisa ukusebenza nokuqina kwe Izinhlayiya ze-Electrode. Ama-Coatings angakhulisa amandla asebenza ngogesi, avikele ukuhlanganiswa kwezinhlayiya, futhi athuthukise ukuxhumana phakathi kwezinhlayiya kanye ne-electrolyte. I-DoPing ingaguqula isakhiwo se-elektroniki futhi ithuthukise izakhiwo ze-electrochemical.

Izicelo zezinhlayiya ze-electrode

Izinhlayiya ze-Electrode ziyizakhi ezibalulekile kumadivayisi ahlukahlukene we-electrochemical:

Amabhethri e-Lithium-ion

Lawa mabhethri anamandla amadivaysi amaningi aphathekayo kagesi nezimoto zikagesi. Ukusebenza kwamabhethri e-lithium-ion athembele kakhulu kwizakhiwo ze Izinhlayiya ze-Electrode isetshenziswe e-cathode nase-anode. Hebei Yaofa Carbon Co, Ltd. (https://www.yaofatanununcu.com/) ngumhlinzeki oholayo wezinto zokwakha ezisezingeni eliphakeme ze-carbon ezisetshenziswa ebhethri le-lithium-ion Izinhlayiya ze-Electrode.

Amaseli kaphethiloli

Amaseli we-Fuel aguqula amandla amakhemikhali abe amandla kagesi, enikeza umthombo wamandla ohlanzekile futhi ofanele. Ukukhethwa kwe Izinhlayiya ze-Electrode Kumaseli kaphethiloli kuncike ohlotsheni lwamafutha asetshenzisiwe kanye nezimo zokusebenza.

Ama-Supercapacitors

Ama-Supercapacitors amadivayisi wokugcina amandla akwazi ukuletha amandla aphezulu namazinga okushaja okusheshayo. Bavame ukusebenzisa i-carbon-based Izinhlayiya ze-Electrode ngenxa yendawo yabo ephezulu yokuvuka kanye nokusebenza kukagesi.

Ukukhetha izinhlayiya ze-elektrode ezifanele

Ukukhetha kufanelekile Izinhlayiya ze-Electrode Idinga ukucubungula ngokucophelela kohlelo lokusebenza oluthile nezimpawu zokusebenza ezifunwayo. Izici ezifana nobuningi bamandla, ukuqina kwamandla, impilo yomjikelezo, izindleko, kanye nokuphepha kumele kuhlolwe.

Ukugcina

Izinhlayiya ze-Electrode ziyizakhi eziyisisekelo kubuchwepheshe obuhlukahlukene be-electrochemical. Ukuqonda izakhiwo zabo, ukukhethwa, kanye nezicelo kubalulekile ekwakheni amadivaysi aphezulu okusebenza. Ukucwaninga okwengeziwe kanye nentuthuko kule ndawo kubalulekile ukuze kuthuthukiswe ukugcinwa kwamandla kanye nobuchwepheshe bokuguqula.Table {ububanzi: 700PX; Margin: 20px Auto; Umngcele-ukuwa kwe-Border: Ukuwa; th, TD {Border: 1px solid #ddd; I-Padding: 8px; I-Tex-Align: Kwesobunxele;} th {Umbala wesekeluzi: # F2F2F2;}
