Girazi kabhoni electrode yakagadzirwa kubva ku nano oxide ine maitiro akasiyana-siyana, akadai sekugadzikana kwakanaka kwemabhatiri, high conductivity, high purity, hapana gasi mu electrode Essence.Easy surface regeneration, diki hydrogen uye oxygen zvinogona, mutengo wakachipa, etc. Zvisinei, izvi zvinonyanya kutaurwa, saka ndezvipi zvakananga zvinokonzerwa ne magnesium oxide mumabhatiri e lithium?
Chokutanga pane zvose, sarudza 10-100g/L dhayamita ye10-100g/L dhayamita pakati pe0.05-10 μm yeTiO2, SiO2, Cr2O3, ZrO2, CeO2, Fe2O3, BaSO, SiC, MgO nezvimwe zvisinganyunguriki zvimedu zvakasimba;zvinhu zvakagadzirwa se lithium ion zvine hunhu hwekuchaja kwakanaka uye kuburitsa kunyatsoita, hukuru hwepamusoro, uye yakagadzikana circulatory performance.
Kechipiri, iyo lithium bhatiri yakanaka zvinhu, nano -magnesium oxide se conductive dopant, inogadzira magnesium doped lithium iron manganese phosphate kuburikidza nekugadzirisa zvikonzero, uye inoenderera mberi inoumba nano-chimiro cheiyo yakanaka electrode zvinhu.Iyo chaiyo yekuburitsa simba inosvika 240mAh/g.Iyi mhando nyowani yezvakanaka electrode zvinhu zvine hunhu hwesimba rakawanda, chengetedzo, uye mitengo yakaderera.Inokodzera kumvura uye colloidal lithium-ion mabhatiri, madiki uye epakati-saizi mapolymers, kunyanya kune akakwira-simba mabhatiri.
Zvadaro, kugona uye kutenderera kuita kwespinel manganate lithium bhatiri yakagadziridzwa.Mu lithium ion bhatiri electrolyte ine spinel lithium manganate seyakanaka zvinhu, nano-magnesium oxide inowedzerwa se deacidifier kubvisa asidhi, iyo yekuwedzera huwandu ndeye 0.5-20% yehuremu hwe electrolyte.Nekubvisa asidi e electrolyte, zvirimo muasidhi yemahara HF mu electrolyte zvinodzikiswa kusvika pasi pe20ppm, izvo zvinoderedza kuparara kweHF kuenda kuLiMn2O4, uye inovandudza kugona uye kutenderera kuita kweLiMn2O4.
Pakupedzisira, padanho rekutanga, nano magnesium oxide se pH regulator inosanganiswa nealkali solution uye ammonia solution semushonga wakaoma, uye inowedzerwa kune yakasanganiswa aqueous solution ine cobalt uye nickel salts kuti iite precipitate Ni-CO complex hydroxides. .
Danho rechipiri nderekuwedzera lithium hydroxide kuNi-CO composite hydroxide, uye kupisa musanganiswa wekurapa pa280-420 °C.
Muchikamu chechitatu, chigadzirwa chinogadzirwa muchikamu chechipiri ndechekupisa kunobatwa munharaunda ye 650-750 ° C, iyo inobatana nenguva yekubatana.Avhareji saizi yelithium composite oxide inodzikira kana kuwanda kwehuwandu hunowedzera zvinoenderana.Kana lithium composite oxide inoshandiswa seanode inoshanda zvinhu, yakakwira simba lithium ion yechipiri bhatiri inogona kuwanikwa, uye iyo chaiyo chiyero che magnesium oxide chiri pasi peiyo chaiyo formula.
