Pre-Magnesium Silicon-Oxygen-Carbon Pre-Mg-SiOC Chinhu cheAnode Chinoshanda Zvakanyanya

Pfupiso yePre-Magnesium Silicon-Oxygen-Carbon

Pre-Magnesium Silicon-Oxygen-Carbon (Pre-Mg-SiOC) imhando inotevera ye lithium-ion battery anode yakagadzirwa kuburikidza ne pre-magnesiation treatment uye carbon composite process uchishandisa silicon oxide sechinhu chisina kugadzirwa. Munguva yekugadzira, magnesium inounzwa muzvikamu zvakagadzikana zve pre-form zvakaita se magnesium silicate mukati mechinhu chacho. Izvi zvinovandudza zvakanyanya kushanda kweCoulombic kwekutanga (ICE). Panguva imwe chete, rutsigiro rwemakanika rwunopihwa ne magnesium silicate framework runonyatso chengetedza kuwedzera kwehuwandu panguva yekuchaja/kuburitsa, nokudaro ruchiwedzera hupenyu hwema cell cycle.

Chigadzirwa ichi chinomiririra tekinoroji yeanode yesilicon-oxygen yechizvarwa chechipiri. Kana ichienzaniswa neanode dzechizvarwa chekutanga dzeSiOx, inoita budiriro inoshamisa mukushanda kwayo kwekutanga, ichipa mhinduro yeanode inoshanda zvakanyanya uye inoenderana nemaitiro emabhatiri ane simba rakawanda.

Zvinhu zvePre-Magnesium Silicon-Oxygen-Carbon

• Kubudirira Kwekutanga Kwakawedzera Zvikuru: Kuburikidza ne pre-magnesiation, stable magnesium silicate phases inoumbwa pachine nguva, zvichidzivirira kushandiswa kwe active lithium. Kushanda kweCoulombic kwekutanga kwakanyanya kupfuura kweSiOx anodes, ine huwandu hwakajairika hunobva pa80% kusvika 83% uye huwandu hwepamusoro hunodarika 89%.
• Kubudirira kweKuwedzera Vhoriyamu: Chikamu chemagnesium silicate chinopa rutsigiro rwakasimba rwemakanika. Kana chakabatanidzwa nechimiro chechinhu chacho chine maburi akavhurika, chinoderedza kushanduka kwehuwandu panguva ye lithiation, zvichiita kuti pave nechokwadi chekuti particles integrity uye electrode structure stability.
• Kuputira Kabhoni Inofambisa: Kuputira kabhoni pamusoro pemvura kunowedzera kufambisa kwemagetsi, kunodzivirira kudonha kwe electrolyte zvakananga pa anode, uye kunokurudzira kuumbwa kwefirimu rakasimba re solid-electrolyte interphase (SEI), zvichiita kuti pave nekugadzikana kwakanyanya kwe cycling.
• Kuenderana Kwakanaka Kwemaitiro: Nekugoverwa kwehukuru hwezvimedu zvakaenzana uye hwindo rakakura rekugadzirisa, chinhu ichi chinoenderana nemasisitimu akasiyana-siyana ekubatanidza, anosanganisira PVDF, PAA, uye CMC/SBR. Chinoratidzawo kubatana kwakanaka kana chikasanganiswa nezvinhu zve graphite anode.

Kugadzirira Masero Emari & Mamiriro Ekuyedza ePre-Magnesium Silicon-Oxygen-Carbon

Kuumbwa kweCR2032 Coin Cell Slurry:
HL-1420: Super P: CN-1 Binder = 8: 1: 1 (nehuremu)

Maitiro ekugadzirira CR2032 Coin Cell Slurry:

1. Yera 339 g yeCN-1 binder wobva wawedzera ku1161 g yemvura yakachena kwazvo. Sanganisa pa600 rpm kwemaminitsi 300 uchishandisa muchina wekusanganisa unomhanya kusvika binder yapararira zvizere.
2. Yera 1.728 g yezvinhu zvinoshanda zveHL-1420 uye 0.216 g yeSuper P muchirongo chekusanganisa. Gaya zvinyoro nyoro kwemaminitsi gumi.
3. Wedzera 6.371 g ye CN-1 binder solution yakagadzirwa mubhodhoro wovhara.
