Hana Burrs a cikin Samar da Batirin Lithium Electrode: Magani don Tsabtace Tsabtace Tsabtace

Thewukar yanke wutar lantarki ta lithium-ion, a matsayin nau'in wukake masu mahimmanci na masana'antu, wukake ne masu zagaye na carbide waɗanda aka tsara don buƙatun aikin yankewa mai matuƙar girma. Burrs yayin yankewa da huda wutar lantarki ta batirin li-ion suna haifar da haɗari mai tsanani. Waɗannan ƙananan buɗaɗɗun suna tsoma baki ga hulɗar lantarki mai kyau, suna rage ƙarfin baturi da kashi 5-15% kai tsaye a cikin mawuyacin hali.

Mafi mahimmanci, burrs suna zama haɗarin aminci - gwaje-gwajen dakin gwaje-gwaje sun nuna ko da fitowar 20μm na iya huda masu rabawa, wanda ke haifar da guduwar zafi. Tasirin kuɗi yana haɗuwa ta hanyoyi da yawa: juriya ta ciki mafi girma yana rage tsawon rayuwar da kashi 30%, yayin da ƙimar tarkacen burrs da ke da alaƙa da burr yawanci yana ƙara kashi 3-8% ga farashin samarwa.

Domin samun ingantaccen aikin yankewa, masana'antun suna buƙatar wukake masu ɗorewa na tungsten carbide waɗanda aka ƙera musamman don kayan lantarki. Wukake masu yankewa na batirin Li-ion na Shen Gong suna nuna tsawon rai fiye da ruwan wukake na yau da kullun a ci gaba da samarwa.

• Aiwatar da jujjuya ruwan wukake a duk bayan sa'o'i 8 na samarwa

• A kiyaye zurfin yankewa na 0.15-0.3mm idan aka kwatanta da kauri na lantarki

• Yi amfani da kayan aikin auna laser don duba lalacewa na mako-mako

Ga sabbin layukan batirin abin hawa masu amfani da makamashi, saitin ruwan wukake na sama/ƙasa da muka daidaita suna samun juriyar yankewa <15μm akai-akai.
