Kupewa Ma Burrs mu Lithium Battery Electrode Production: Solutions for Clean Slitting

Thelithiamu-ion elekitirodi wodula mpeni, monga mtundu wovuta kwambiri wa mipeni ya mafakitale, ndi mipeni yozungulira yozungulira ya carbide yopangidwa kuti ikhale yofunikira kwambiri. Tizigawo tating'onoting'ono timeneti timasokoneza kulumikizana koyenera kwa ma elekitirodi, kumachepetsa mwachindunji mphamvu ya batri ndi 5-15% pazovuta kwambiri.

Choyipa kwambiri, ma burrs amakhala owopsa - kuyesedwa kwa labotale kumawonetsa ngakhale ma protrusions 20μm amatha kubowola zolekanitsa, zomwe zimatsogolera kuthawa kwamafuta. Mavuto azachuma amabwera kudzera munjira zingapo: kukana kwakukulu kwamkati kumachepetsa moyo ndi 30%, pomwe mitengo yazachuma yokhudzana ndi burr nthawi zambiri imawonjezera 3-8% kumitengo yopangira.

Kuti agwire ntchito yodalirika, opanga amafunika mipeni yokhazikika ya tungsten carbide slitter yomwe imapangidwira zida za electrode. Mipeni ya Shen Gong ya li-ion battery electrode electrode imawonetsa moyo wautali kusiyana ndi masamba omwe amapangidwa mosalekeza. Chinsinsichi chili muzinthu zitatu zatsopano: 1) Magawo amtundu wa Ultra-fine grain carbide omwe amagonjetsedwa ndi micro-chipling, 2) Zovala za TiCN za mwiniwake zimachepetsa mkuwa / aluminium adhesion ndi 40%, ndi 3) μm-level m'mphepete kumaliza zomwe zimalepheretsa mapangidwe oyambirira a burr.

Njira zabwino zogwirira ntchito zimawonjezera zotsatira:

• Yambitsani kuzungulira kwa masamba pa maola 8 aliwonse opangira

• Sungani kuya kwa 0.15-0.3mm kudula poyerekeza ndi makulidwe a electrode

• Gwiritsani ntchito zida zoyezera laser pakuwunika kwa sabata iliyonse

Pamizere ya batri yamagetsi atsopano, ma seti athu ofananira apamwamba / otsika amakwaniritsa <15μm kupirira kodulidwa mosalekeza. Kafukufuku akuwonetsa kuchepa kwa zolakwika zokhudzana ndi burr atasinthira ku Shen Gong's system. Kumbukirani - ngakhale masamba a premium slitting amawononga 20-30% mochulukirapo poyambirira, amalepheretsa kutayika kwakukulu kutsika kuchokera ku zinyalala ndi kulephera kwa batri.

Ngati mukukumana ndi zovuta pakuboola ma elekitirodi, chonde funsani gulu laukadaulo la ShenGong: howard@scshengong.com
