Kuduladula ndi kubowola kwa ma electrode a batire ya li-ion kumabweretsa zoopsa zazikulu. Ma electrode ang'onoang'ono awa amasokoneza kukhudzana bwino kwa ma electrode, zomwe zimachepetsa mphamvu ya batire ndi 5-15% pazochitika zoopsa.
Chofunika kwambiri, ma burrs amakhala oopsa - mayeso a labotale akuwonetsa kuti ngakhale ma burrs a 20μm amatha kuboola ma separator, zomwe zimapangitsa kuti kutentha kuchoke. Kuchuluka kwa ndalama kumawonjezeka kudzera m'njira zosiyanasiyana: kukana kwakukulu kwamkati kumachepetsa moyo wa kuzungulira ndi 30%, pomwe mitengo yokhudzana ndi burr nthawi zambiri imawonjezera 3-8% pamitengo yopangira.
Kuti ntchito yodulira ikhale yodalirika, opanga amafunika mipeni yolimba ya tungsten carbide yopangidwa makamaka kuti igwiritsidwe ntchito pa zipangizo zama electrode. Mipeni yodulira ya Shen Gong ya li-ion batire imasonyeza kuti imakhala ndi moyo wautali kuposa masamba wamba popanga mosalekeza. Chinsinsi chili mu zinthu zitatu zatsopano: 1) Ma substrates a ultra-fine grain carbide omwe sagonjetsedwa ndi micro-chipping, 2) Zophimba za TiCN zomwe zimachepetsa kumatirira kwa mkuwa/aluminium ndi 40%, ndi 3) μm-level edge finishing yomwe imaletsa kupangika kwa burr koyamba.
Njira zabwino zogwirira ntchito zimawonjezera zotsatira:
• Ikani kusinthana kwa masamba maola 8 aliwonse opangira
• Sungani kuya kwa kudula kwa 0.15-0.3mm poyerekeza ndi makulidwe a elekitirodi.
• Gwiritsani ntchito zida zoyezera za laser poyang'anira kuvala kwa mlungu uliwonse
Pa mabatire atsopano amagetsi a galimoto, mabala athu apamwamba/apansi ofanana amakwaniritsa kulekerera kochepera 15μm nthawi zonse. Kafukufuku wa zitsanzo akuwonetsa kuchepa kwa zolakwika zokhudzana ndi burr mutasintha kupita ku dongosolo la Shen Gong. Kumbukirani - ngakhale kuti mabatire apamwamba odulira amawononga ndalama zochulukirapo ndi 20-30% poyamba, amaletsa kutayika kwakukulu kwa mabatire chifukwa cha zinyalala ndi kuwonongeka kwa mabatire.
Ngati mukukumana ndi mavuto a burr pakudula kwa ma electrode, chonde funsani gulu la akatswiri la ShenGong:howard@scshengong.com
