amabhethri e-thium-ion anezinhlobonhlobo zezinhlelo zokusebenza. Ngokuya ngezigaba zezindawo zokufaka izicelo, ingahlukaniswa ibe ibhethri yokugcina amandla, ibhethri lamandla nebhethri lama-electronics omthengi.
- Ibhethri yokugcina amandla ihlanganisa isitoreji samandla okuxhumana, isitoreji samandla, amasistimu asakazwa amandla, njll.;
- Ibhethri lamandla lisetshenziswa kakhulu emkhakheni wamandla, ukusebenzela imakethe kufaka phakathi izimoto zamandla amasha, ama-forklift kagesi, njll.;
- Ibhethri lama-elekthronikhi omthengi lihlanganisa inkambu yomthengi neyezimboni, okuhlanganisa ukulinganisa okuhlakaniphile, ukuphepha okukhaliphile, ezokuthutha ezihlakaniphile, I-inthanethi Yezinto, njll.
Ibhethri ye-lithium-ion iyisistimu eyinkimbinkimbi, ikakhulukazi eyakhiwe i-anode, i-cathode, i-electrolyte, isihlukanisi, umqoqi wamanje, i-binder, i-ejenti eqhubayo nokunye, okubandakanya ukusabela okuhlanganisa ukusabela kwe-electrochemical kwe-anode ne-cathode, i-lithium ion conduction kanye ne-electronic conduction, kanye nokusabalalisa ukushisa.
Inqubo yokukhiqiza amabhethri e-lithium yinde, futhi kunezinqubo ezingaphezu kuka-50 ezihilelekile kule nqubo.
Amabhethri e-lithium angahlukaniswa abe amabhethri angama-cylindrical, amabhethri egobolondo le-aluminium yesikwele, amabhethri esikhwama kanye namabhethri e-blade ngokusho kwefomu. Kukhona umehluko othile enqubweni yabo yokukhiqiza, kodwa jikelele inqubo yokukhiqiza ibhethri ye-lithium ingahlukaniswa ibe yinqubo yangaphambili (ukukhiqizwa kwe-electrode), inqubo yesigaba esiphakathi (i-cell synthesis), kanye nenqubo yokugcina emuva (ukwakheka nokupakisha).
Inqubo yangaphambili yokwenziwa kwebhethri ye-lithium izokwethulwa kulesi sihloko.
Umgomo wokukhiqiza wenqubo yangaphambili ukuqedela ukwakhiwa kwe-electrode (i-anode ne-cathode). Inqubo yayo eyinhloko ihlanganisa: i-slurrying/ukuxuba, ukugqoka, i-calendering, ukusika, nokusika ukufa.
Ukuxubha/Ukuxubha
I-Slurrying/mixing iwukuhlanganisa izinto eziqinile zebhethri ze-anode ne-cathode ngokulinganayo bese wengeza isincibilikisi ukwenza udaka. Ukuxutshwa kwe-slurry kuyisiqalo se-front end yomugqa, futhi kuyisandulela sokuqedwa kokunamathela okulandelayo, i-calendering nezinye izinqubo.
I-lithium battery slurry ihlukaniswe yaba i-electrode slurry e-positive kanye ne-negative electrode slurry. Faka izinto ezisebenzayo, i-conductive carbon, thickener, binder, additive, solvent, njll. ku-mixer ngokulingana, Ngokuxuba, thola ukuhlakazeka okufanayo kwe-solid-liquid suspension slurry for coating.
Ukuxubana kwekhwalithi ephezulu kuyisisekelo sokuqedwa kwekhwalithi ephezulu yenqubo elandelayo, ezothinta ngokuqondile noma ngokungaqondile ukusebenza kokuphepha nokusebenza kwe-electrochemical yebhethri.
Ukugqoka
Ukugqoka kuyinqubo yokumboza izinto ezisebenzayo ezisebenzayo kanye nezinto ezingezinhle ezisebenzayo kumafoyili e-aluminium nethusi ngokulandelana, futhi ukuwahlanganisa nama-conductive agents kanye ne-binder ukwenza ishidi le-electrode. Ama-solvents abe esesuswa ngokomiswa kuhhavini ukuze into eqinile iboshwe ku-substrate ukwenza ikhoyili yeshidi le-electrode elilungile nelingalungile.
I-Cathode ne-anode coating
Izinto zokwakha ze-Cathode: Kunezinhlobo ezintathu zezinto zokwakha: isakhiwo se-laminated, isakhiwo se-spinel kanye nesakhiwo se-olivine, esihambisana nezinto ze-ternary (kanye ne-lithium cobaltate), i-lithium manganate (LiMn2O4) ne-lithium iron phosphate (LiFePO4) ngokulandelanayo.
Izinto ze-anode: Okwamanje, izinto ze-anode ezisetshenziswa kubhethri ye-lithium-ion yokuhweba ikakhulukazi zifaka izinto zekhabhoni nezinto ezingezona ikhabhoni. Phakathi kwazo, izinto ze-carbon zihlanganisa i-graphite anode, esetshenziswa kakhulu okwamanje, ne-disordered carbon anode, i-hard carbon, i-soft carbon, njll; izinto ezingezona carbon zihlanganisa anode silicon-based, lithium titanate (LTO) nokunye.
Njengesixhumanisi esiyinhloko senqubo yangaphambili, ikhwalithi yokusetshenziswa yenqubo yokumboza ithinta kakhulu ukuvumelana, ukuphepha kanye nomjikelezo wokuphila webhethri eliqediwe.
I-Calender
I-electrode eboshwe iphinde ihlanganiswe nge-roller, ukuze into esebenzayo kanye nomqoqi basondelene eduze, ukunciphisa ibanga lokuhamba kwama-electron, ukwehlisa ubukhulu be-electrode, okwandisa umthamo wokulayisha. Ngesikhathi esifanayo, ingakwazi ukwehlisa ukumelana kwangaphakathi kwebhethri, ikhuphule izinga lebhethri, futhi ithuthukise izinga lokusetshenziswa kwevolumu yebhethri ukuze kwandiswe umthamo webhethri.
I-flatness ye-electrode ngemva kwenqubo ye-calendering izothinta ngokuqondile umphumela wenqubo yokuhlukanisa okulandelayo. Ukufana kwento esebenzayo ye-electrode nakho kuzothinta ngokungaqondile ukusebenza kweseli.
Ukusika
Ukusika i-longitudinal ukusika ikhoyili ye-electrode ebanzi ibe izingcezu ezincane zobubanzi obudingekayo. Ekusikeni, i-electrode ihlangabezana nesenzo sokugunda bese iphuka, Ukuvuleka komphetho ngemva kokusikwa (akukho burr nokuguquguquka) kuyisihluthulelo sokuhlola ukusebenza.
Inqubo yokwenza i-electrode ihlanganisa ithebhu ye-welding electrode, ukusebenzisa iphepha lokunamathisela eliyisivikelo, ukugoqa ithebhu ye-electrode nokusebenzisa i-laser ukusika ithebhu ye-electrode ngenqubo yokugoqa elandelayo. I-Die-cutting ukugxiviza nokubumba i-electrode eboshwe ngenqubo elandelayo.
Ngenxa yezidingo eziphakeme zokusebenza kokuphepha kwamabhethri e-lithium-ion, ukunemba, ukuzinza kanye nokuzenzakalelayo kwemishini kuyadingeka kakhulu kwinqubo yokukhiqiza ibhethri ye-lithium.
Njengomholi wemishini yokulinganisa i-lithium electrode, i-Dacheng Precision yethule uchungechunge lwemikhiqizo yokulinganisa i-electrode kwinqubo yangaphambili yokukhiqiza ibhethri ye-lithium, njenge-X/β-ray areal density gauge, ukushuba kwe-CDM kanye ne-areal density gauge, i-laser thickness gauge nokunye.
- I-Super X-Ray areal density gauge
Iyakwazi ukuzivumelanisa nezimo esilinganisweni sobubanzi obungaphezu kuka-1600 mm bokunamathela, isekela ukuskena okunesivinini esikhulu, futhi ithola izici ezinemininingwane njengezindawo ezizacile, imihuzuko, namaphethelo e-ceramic. Ingasiza nge-closed-loop coating.
- I-X/β-ray ye-areal density gauge
Isetshenziswa enqubweni yokuhlanganisa i-electrode yebhethri kanye nenqubo yokuhlanganisa yesihlukanisi se-ceramic ukwenza ukuhlolwa kwe-inthanethi kokuminyana kwendawo yento elinganisiwe.
- Ubukhulu be-CDM & ne-areal density gauge
Ingasetshenziswa enqubweni yokumboza: ukutholwa ku-inthanethi kwezici ezinemininingwane zama-electrode, njengokugeja okugejiwe, ukushoda kwempahla, imihuzuko, ugqinsi lwezindawo ezacile, ukutholwa kogqinsi kwe-AT9, njll.;
- Uhlelo lokulinganisa lokulandela ngomkhondo olunohlaka oluningi
Isetshenziselwa ukuhlanganisa inqubo ye-cathode ne-anode yamabhethri e-lithium. Isebenzisa amafreyimu wokuskena amaningi ukwenza izilinganiso zokulandelela ezivumelanayo kuma-electrode. Uhlelo lokulinganisa lokulandela ngomkhondo olunezinhlaka ezinhlanu luyakwazi ukuhlola ifilimu emanzi, inani le-net coating, kanye ne-electrode.
- I-gauge yokuqina kwe-laser
Isetshenziselwa ukuthola i-electrode kunqubo yokumboza noma inqubo ye-calendering yamabhethri e-lithium.
- Ukujiya okungaxhunyiwe ku-inthanethi kanye ne-dimension gauge
Isetshenziselwa ukuthola ukushuba nobukhulu bama-electrode enqubweni yokumboza noma inqubo ye-calendering yamabhethri e-lithium, okuthuthukisa ukusebenza kahle nokuvumelana.
