Ho Thibela Li-Burrs Tlhahisong ea Li-electrode tsa Lithium Battery: Litharollo tsa ho Slitting e Hloekileng

Thethipa ea ho thiba ea electrode ea lithium-ion, e le mofuta oa bohlokoa oa lithipa tsa indasteri, ke lithipa tse chitja tsa carbide tse nepahetseng tse etselitsoeng litlhoko tsa ts'ebetso ea ho petsoha haholo. Li-burrs nakong ea ho petsoha le ho phunya ha electrode ea betri ea li-ion li baka likotsi tse tebileng tsa boleng. Li-protrusion tsena tse nyane li sitisa ho kopana hantle ha electrode, li fokotsa ka ho toba bokhoni ba betri ka 5-15% maemong a boima.

Habohlokoa le ho feta, li-burrs li fetoha likotsi tsa polokeho - liteko tsa laboratori li bontša hore esita le li-protrusion tsa 20μm li ka phunya li-aparthor, e leng se lebisang ho thelleng ha mocheso. Tšusumetso ea lichelete e kopana le litsela tse ngata: khanyetso e phahameng ea ka hare e fokotsa bophelo ba potoloho ka 30%, ha litefiso tsa lithōle tse amanang le burr hangata li eketsa 3-8% litšenyehelong tsa tlhahiso.

Bakeng sa ts'ebetso e tšepahalang ea ho taboha, bahlahisi ba hloka lithipa tse tiileng tsa tungsten carbide tse entsoeng ka ho khetheha bakeng sa thepa ea electrode. Lithipa tse tabohang tsa electrode ea betri ea li-ion ea Shen Gong li bontša bophelo bo bolelele ho feta mahare a tloaelehileng tlhahisong e tsoelang pele. Sephiri se ho lintho tse ncha tse tharo: 1) Li-substrate tsa carbide ea lijo-thollo tse ntle haholo tse hanelang ho petsoha ha micro-chipping, 2) Liaparo tsa TiCN tse nang le thepa tse fokotsang ho khomarela ha koporo/aluminium ka 40%, le 3) ho qeta moeli oa boemo ba μm ho thibelang ho thehoa ha burr ea pele.

Mekhoa e metle ea ts'ebetso e ntlafatsa liphetho tse latelang:

• Kenya tšebetsong phetolo ea mahare lihora tse ling le tse ling tse 8 tsa tlhahiso

• Boloka botebo ba ho seha ba 0.15-0.3mm ha bo bapisoa le botenya ba electrode

• Sebelisa lisebelisoa tsa ho lekanya ka laser bakeng sa tlhahlobo ea ho roala beke le beke

Bakeng sa mela e mecha ea libeteri tsa koloi ea matla, li-blade tsa rona tse ka holimo/tlase tse tsamaellanang li fihlella mamello ea ho seha e ka tlase ho 15μm ka ho latellana. Lithuto tsa linyeoe li bontša phokotso ea liphoso tse amanang le burr kamora ho fetohela tsamaisong ea Shen Gong. Hopola - leha li-blade tsa slitting tsa boleng bo holimo li bitsa 20-30% ho feta qalong, li thibela tahlehelo e phahameng ka ho fetisisa e theohelang ka lebaka la ho hloleha ha lithōle le betri.
