mabhatiri ethium-ion ane huwandu hwakawanda hwekushandisa. Zvinoenderana nekupatsanurwa kwenzvimbo dzekushandisa, inogona kukamurwa kuita bhatiri rekuchengetedza simba, bhatiri remagetsi uye bhatiri remagetsi evatengi.
- Bhatiri rekuchengetedza simba rinovhara kutaurirana simba rekuchengetedza, simba rekuchengetedza simba, akagoverwa simba masisitimu, nezvimwe;
- Simba bhatiri rinonyanya kushandiswa mumunda wesimba, kushumira pamusika kusanganisira itsva magetsi emagetsi, magetsi forklifts, nezvimwewo;
- Bhatiri remagetsi evatengi rinovhara mutengi uye maindasitiri munda, kusanganisira smart metering, hungwaru chengetedzo, hungwaru hwekufambisa, Internet yezvinhu, nezvimwe.
Lithium-ion bhatiri hurongwa hwakaoma, hunonyanya kuumbwa neanode, cathode, electrolyte, separator, ikozvino muunganidzi, binder, conductive agent uye zvichingodaro, zvinosanganisira maitiro anosanganisira electrochemical reaction yeanode uye cathode, lithium ion conduction uye electronic conduction, pamwe nekupisa kupisa.
Maitiro ekugadzira mabhatiri e lithium akareba, uye anopfuura makumi mashanu maitiro anobatanidzwa mukuita.
Lithium mabhatiri anogona kukamurwa kuita cylindrical mabhatiri, square aluminium shell mabhatiri, pouch mabhatiri uye blade mabhatiri zvinoenderana nefomu. Pane misiyano mukuita kwavo kwekugadzira, asi zvakazara iyo lithium bhatiri yekugadzira maitiro inogona kukamurwa kuita yekumberi-yekupedzisira maitiro (electrode kugadzira), yepakati-nhanho maitiro (sero synthesis), uye kumashure-yekupedzisira maitiro (kuumbwa uye kurongedza).
Iyo yekumberi-yekupedzisira maitiro ekugadzira lithium bhatiri ichaunzwa mune ino chinyorwa.
Chinangwa chekugadzira chepamberi-yekupedzisira maitiro ndechekupedzisa kugadzirwa kwe electrode (anode uye cathode). Maitiro ayo makuru anosanganisira: slurrying / kusanganisa, kupfeka, calendering, kucheka, uye kufa kucheka.
Slurrying/Kusanganisa
Kutsveta/kusanganisa kusanganisa zvinhu zvakasimba zvebhatiri zveanode uye cathode zvakaenzana wobva wawedzera sonzura kuita slurry. Slurry kusanganisa ndiyo inotangira kumberi kwekupedzisira kwemutsara, uye ndiyo inotangira pakupedzwa kwekuzotevera kupfekedza, calendering uye mamwe maitiro.
Lithium bhatiri slurry yakakamurwa kuita yakanaka electrode slurry uye negative electrode slurry. Isa zvinhu zvinoshanda, conductive kabhoni, thickener, binder, additive, solvent, etc. mumusanganisi muchiyero, Nekusanganisa, wana yunifomu kuparadzirwa kwe solid-liquid suspension slurry yekupfekedza.
Kusanganiswa kwepamusoro-soro ndiyo nheyo yekupedzwa kwepamusoro-soro yemaitiro anotevera, ayo achakanganisa zvakananga kana zvisina kunanga kuchengetedzwa kwekuchengetedza uye electrochemical performance yebheteri.
Coating
Coating inzira yekupfekedza iyo yakanaka inoshanda zvinhu uye isina kunaka inoshanda zvinhu paaluminium nemhangura foil zvichiteerana, uye nekuzvisanganisa nema conductive agents uye binder kugadzira electrode sheet. Izvo zvinonyungudutsa zvino kubviswa nekuomesa muchoto kuitira kuti chinhu chakasimba chinosungirirwa kune substrate kuita yakanaka uye yakaipa electrode sheet coil.
Cathode uye anode coating
Cathode zvinhu: Kune marudzi matatu ezvigadzirwa: laminated structure, spinel structure uye olivine structure, inoenderana neternary materials (uye lithium cobaltate), lithium manganate (LiMn2O4) uye lithium iron phosphate (LiFePO4) maererano.
Anode zvinhu: Parizvino, anode zvinhu zvinoshandiswa mukutengesa lithium-ion bhatiri zvinonyanya zvinosanganisira kabhoni zvinhu uye zvisiri kabhoni zvinhu. Pakati pavo, carbon zvinhu zvinosanganisira graphite anode, iyo inonyanya kushandiswa panguva ino, uye disordered carbon anode, hard carbon, soft carbon, nezvimwewo; zvisiri-kabhoni zvinhu zvinosanganisira silicon-based anode, lithium titanate (LTO) zvichingodaro.
Seyakanyanya chinongedzo chepamberi-yekupedzisira maitiro, iyo yekuuraya mhando yekuputira maitiro inokanganisa zvakanyanya kuenderana, kuchengetedzeka uye kutenderera kwehupenyu hwebhatiri rakapedzwa.
Calender
Iyo electrode yakavharidzirwa inowedzerwazve ne roller, kuitira kuti chinhu chinoshanda uye muunganidzi ave pedyo nekubatana, kuderedza kufamba kwema electrons, kuderedza kukora kwe electrode, kuwedzera simba rekutakura. Panguva imwecheteyo, inogona kuderedza kupikisa kwemukati kwebhatiri, kuwedzera conductivity, uye kugadzirisa huwandu hwekushandisa kwebhatiri kuitira kuti uwedzere huwandu hwebhatiri.
Iyo flatness ye electrode mushure mekuita calendering inozokanganisa zvakananga mhedzisiro yeinotevera slitting process. Kufanana kwechinhu chinoshanda che electrode kuchakanganisawo zvisina kunanga kuita kwesero.
Slitting
Slitting ndiyo inoenderera mberi longitudinal kucheka kweyakafara electrode coil kuita zvidimbu zvitete zvehupamhi hunodiwa. Mukutsemura, electrode inosangana neshear action uye inoputsika, The edge flatness mushure mekucheka (hapana burr uye flexing) ndiyo kiyi yekuongorora kushanda.
Maitiro ekugadzira electrode anosanganisira welding electrode tab, kushandisa inodzivirira inonamira bepa, kuputira tebhu ye electrode uye kushandisa laser kucheka tebhu ye electrode kune inotevera mhepo. Kufa-kucheka ndiko kutsika uye kugadzira iyo yakavharwa electrode kune inotevera maitiro.
Nekuda kwezvinodiwa zvakanyanya zvekuchengetedza mabhatiri e-lithium-ion, iko kurongeka, kugadzikana uye otomatiki yemidziyo inodiwa zvakanyanya mukuita kwe lithium bhatiri.
Sezvo ari mutungamiri mumagetsi ekuyera e-lithium electrode, Dacheng Precision yakatanga mutsara wezvigadzirwa zvekuyerwa kwe electrode mumutambo wepamberi wekugadzira lithium bhatiri, zvakadai se X / β-ray areaal density gauge, CDM thickness uye areal density gauge, laser thickness gauge uye zvichingodaro.
- Super X-Ray aal density geji
Inochinjika kune kuyerwa kweanopfuura 1600 mm hupamhi hwejasi, inotsigira yekupedzisira-yepamusoro-kumhanya scanning, uye inoona zvakadzama maficha senge nzvimbo dzakatetepa, makwara, uye ceramic mipendero. Inogona kubatsira nekuvhara-loop coating.
- X/ beta-ray yenzvimbo density geji
Inoshandiswa mubhatiri electrode coating process uye separator ceramic coating process kuitisa online bvunzo yeareal density yechinhu chakayerwa.
- CDM ukobvu & nzvimbo density geji
Inogona kuiswa kune maitiro ekuputira: pamhepo kutariswa kweakadzama maficha emagetsi, akadai seakarasika coating, kushomeka kwezvinhu, zvikweshwa, ukobvu contours yenzvimbo dzakatetepa, AT9 ukobvu kuona, nezvimwewo;
- Multi-frame synchronous yekutevera yekuyera sisitimu
Inoshandiswa kupfekedza maitiro e cathode uye anode ye lithium mabhatiri. Inoshandisa akawanda scanning mafuremu kuita synchronous tracking zviyero pama electrode. Mashanu-frame synchronous yekuyera yekuyera sisitimu inokwanisa kuongorora firimu rakanyorova, mambure ekupfekedza huwandu, uye electrode.
- Laser ukobvu gauge
Inoshandiswa kuona iyo electrode mukugadzira nzira kana calendering maitiro e lithium mabhatiri.
- Off-line ukobvu & dimension geji
Inoshandiswa kuona ukobvu uye chiyero chemagetsi emagetsi mukuputira kana kuti calendering mabhatiri e lithium, iyo inovandudza kushanda kwayo uye kuenderana.
