Kudzivirira Burrs muLithium Battery Electrode Production: Mhinduro dzeClean Slitting

Iyobanga rekuchekerera re lithium-ion electrode, semhando yakakosha yemapanga emuindasitiri, mapanga ecarbide akatenderera akagadzirwa zvakanaka akagadzirirwa kushanda zvakanaka kwazvo. Mabhara panguva yekutsemuka kwemagetsi ebhatiri re li-ion anoburitsa nekubaya mabhatiri anogadzira njodzi dzakakomba dzemhando yepamusoro. Maburi madiki aya anokanganisa kubatana kwemagetsi nema electrode, zvichideredza zvakananga kugona kwebhatiri ne5-15% muzviitiko zvakakomba.

Zvakanyanya kukosha, maburrs anova njodzi dzekuchengetedza - bvunzo dzemurabhoritari dzinoratidza kuti kunyange 20μm protrusions dzinogona kuboora ma separators, zvichikonzera kuti kupisa kupfuure. Kukanganisa kwemari kunowedzera kuburikidza nenzira dzakasiyana-siyana: kusimba kwakanyanya kwemukati kunoderedza hupenyu hwe cycle ne30%, nepo huwandu hwemaburrs hune chekuita nemaburrs hunowanzo kuwedzera 3-8% kumitengo yekugadzira.

Kuti kucheka kushande zvakanaka, vagadziri vanoda mapanga e tungsten carbide akasimba akagadzirirwa zvinhu zve electrode. Mapanga e Shen Gong e li-ion battery electrode slitting anoratidza hupenyu hurefu kupfuura mapanga akajairwa mukugadzirwa nguva dzose. Chakavanzika chiri muzvinhu zvitatu zvitsva: 1) Ultra-fine grain carbide substrates inodzivirira micro-chipping, 2) Proprietary TiCN coatings inoderedza copper/aluminium adhesion ne40%, uye 3) μm-level edge finishing inodzivirira kutanga kwe burr.

Maitiro akanaka ekushanda anowedzerawo mhedzisiro:

• Shandisai kutenderedza mapanga maawa masere ega ega ekugadzira

• Chengetedza kudzika kwekucheka kwe 0.15-0.3mm zvichienderana nekukora kwe electrode

• Shandisa maturusi ekuyera nelaser pakuongorora kupfeka kwevhiki nevhiki

Kune mabhatiri matsva emotokari ane simba, mabheti edu epamusoro/ezasi akaenzana anowana kushivirira kwekucheka kusingasviki 15μm nguva dzose. Zvidzidzo zvinoratidza kudzikira kwezvikanganiso zvine chekuita neburr mushure mekushandura kuenda kuShen Gong's system. Yeuka - nepo mabhatiri epamusoro anodhura 20-30% kupfuura pakutanga, anodzivirira kurasikirwa kwakanyanya kubva pakurasikirwa kwemabhatiri.
