Ukuthintela iiBurrs kwiLithium Battery Electrode Production: Izisombululo zeClean Slitting

Iimela yokunqumla i-electrode ye-lithium-ion, njengohlobo olubalulekileyo lweemela zoshishino, ziimela ze-carbide ezijikelezayo ezichanekileyo ezenzelwe iimfuno zokusebenza kokunqumla okuphezulu kakhulu. Iibherr ngexesha lokunqumla kunye nokubhoboza i-electrode yebhetri ye-li-ion zenza umngcipheko omkhulu womgangatho. Ezi protrusions zincinci ziphazamisana nokudibana kwe-electrode ngokufanelekileyo, zinciphisa ngokuthe ngqo amandla ebhetri nge-5-15% kwiimeko ezinzima.

Okubaluleke ngakumbi kukuba, ii-burrs ziba yingozi kukhuseleko - uvavanyo lwelabhoratri lubonisa ukuba nee-protrusions ezingama-20μm zinokugqobhoza izahluli, nto leyo ekhokelela ekubalekeni kobushushu. Impembelelo yezemali ihlangana ngeendlela ezininzi: ukumelana okuphezulu kwangaphakathi kunciphisa ubomi bomjikelo nge-30%, ngelixa amazinga e-scrap anxulumene ne-burr edla ngokongeza i-3-8% kwiindleko zemveliso.

Ukuze ukusebenza kakuhle kokunqumla okuthembekileyo, abavelisi bafuna iimela ze-tungsten carbide eziqinileyo ezenzelwe ngokukodwa izixhobo ze-electrode. Iimela ze-Shen Gong zokunqumla i-electrode yebhetri ye-li-ion zibonisa ubomi obude kuneeblade eziqhelekileyo ekuvelisweni okuqhubekayo. Imfihlo ilele kwizinto ezintathu ezintsha: 1) Ii-substrates ze-carbide zengqolowa ezicolekileyo kakhulu ezimelana nokuqhekeka kwe-micro-chipping, 2) Iingubo ze-TiCN ezizimeleyo ezinciphisa ukunamathela kwe-copper/aluminium ngama-40%, kunye ne-3) ukugqitywa komphetho we-μm-level okuthintela ukwakheka kwe-burr yokuqala.

Iindlela ezilungileyo zokusebenza ziyaphucula iziphumo:

• Sebenzisa ujikeleziso lweeblade rhoqo emva kweeyure ezisi-8 zemveliso

• Gcina ubunzulu bokusika obuyi-0.15-0.3mm xa kuthelekiswa nobukhulu be-electrode

• Sebenzisa izixhobo zokulinganisa nge-laser xa uhlola ukuguguleka kweveki nganye

Kwimigca yebhetri yesithuthi esitsha samandla, iiseti zethu zeeblade eziphezulu/ezisezantsi ezihambelanayo zifikelela ku-<15μm ukunyamezelana kokusika rhoqo. Izifundo zetyala zibonisa ukuncipha kweziphene ezinxulumene ne-burr emva kokutshintshela kwinkqubo kaShen Gong. Khumbula – nangona iiblade ze-slitting slitting ezikumgangatho ophezulu zibiza ngaphezulu ngama-20-30% ekuqaleni, zithintela ilahleko eziphezulu kakhulu ezivela kwi-slack kunye nokusilela kwebhetri.
