Alumina zvirokwazvo ndeimwe yemhando dzinoshandiswa zvakanyanya uye dzinoshandiswa zvakanyanya.Unogona kuzviona kwese kwese.Kuti uite izvi, kuita kwakanakisa kwealumina pachayo uye mutengo wakaderera wekugadzira ndivo vanonyanya kupa.
Pano kusuma zvakare yakakosha zvikuru application yealumina powder, kureva, lithium bhatiri diaphragm coating.Diaphragm seimwe yezvikamu zvakakosha zvelithium-ion bhatiri, inogona kudzivisa kushamwaridzana kwakanaka uye kusina kunaka uye kukurudzira lithium ion shuttle pakati pemagetsi, kutarisa kushanda nekuchengetedzwa kwebhatiri.Iyo yechinyakare polyolefin diaphragm ine yakaderera kunyunguduka uye kusagadzikana kusimba pakupisa kwakanyanya, izvo zvinokanganisa zvakanyanya kuchengetedzeka kwebhatiri, ikozvino inorganic ultrafine poda coating kana composite modified polymer ndiyo imwe yenzira dzinoshanda dzekuvandudza kugadzikana kwekupisa kwe diaphragm.
Kuti uvandudze kushanda kwepamusoro-tembiricha ye lithium bhatiri separators, aluminium oxide particles inogona kuputirwa pamusoro pe polyolefin separators nerubatsiro rwepolymer binders.Alumina inonyanya kutamba mukana wekudzivirira kwekushisa kwepamusoro, uye inogona kuchengetedza kutendeseka kwediaphragm kunyange pakupisa kwakanyanya kwe180 ° C.Pamusoro pezvo, zvakare inoregedza HF yemahara mu electrolyte kuvandudza asidi kuramba uye kuchengetedza kuita kwebhatiri;inogona kuumba mhinduro yakasimba mubhatiri re lithium kuti ivandudze chiyero chekugona uye kutenderera kuita, ine yakanaka wettability, uye ine imwe Liquid absorption uye yemvura kuchengetedza kugona, nezvimwe.
Panyaya yekushandisa, alumina-yakavharwa lithium bhatiri separators inofarirwa nevatungamiriri vazhinji veindasitiri.Makambani akadai saSanyo, LG, uye Maxell ese atora alumina-coated separators kuti avandudze mashandiro ebhatiri.
Zhengzhou Xinli Wear-Resistant Materials Co., Ltd. inogona kupaalumina powdernokuda kwezvinangwa zvakasiyana-siyana.Kugamuchirwa kuisa odha yekubvunza.
