bateri ya ithium-ion ifite intera nini ya porogaramu. Ukurikije ibyiciro byakoreshwaga, birashobora kugabanywamo bateri yo kubika ingufu, bateri yumuriro na batiri kubikoresho bya elegitoroniki.
- Batteri yo kubika ingufu ikubiyemo ububiko bwitumanaho, kubika ingufu, gukwirakwiza ingufu, nibindi.;
- Amashanyarazi akoreshwa cyane mubijyanye nimbaraga, gukorera isoko harimo ibinyabiziga bishya byingufu, forklifts yamashanyarazi, nibindi.;
- Bateri ya elegitoroniki yumuguzi ikubiyemo abaguzi ninganda, harimo gupima ubwenge, umutekano wubwenge, ubwikorezi bwubwenge, interineti yibintu, nibindi.
Batiri ya Litiyumu-ion ni sisitemu igoye, igizwe ahanini na anode, cathode, electrolyte, itandukanya, ikusanyirizo ryubu, binder, umukozi uyobora nibindi nibindi, birimo reaction zirimo reaction ya electrochemic reaction ya anode na cathode, itwara rya lithium ion hamwe nuyoboro wa elegitoronike, ndetse no gukwirakwiza ubushyuhe.
Igikorwa cyo gukora bateri ya lithium ni ndende, kandi inzira zirenga 50 zigira uruhare mubikorwa.
Batteri ya Litiyumu irashobora kugabanywamo bateri ya silindrike, bateri ya aluminiyumu ya kare, bateri yumufuka na bateri ya blade ukurikije ifishi. Hariho itandukaniro mubikorwa byabo byo kubyaza umusaruro, ariko muri rusange inzira yo gukora batiri ya lithium irashobora kugabanwa mubikorwa byimbere (gukora electrode), icyiciro cyo hagati (synthesis selile), hamwe nibikorwa byanyuma (gushiraho no gupakira).
Inzira-yanyuma yo gukora batiri ya lithium izatangizwa muriyi ngingo.
Intego yo kubyaza umusaruro inzira-yanyuma ni ukurangiza gukora electrode (anode na cathode). Inzira nyamukuru yacyo harimo: gutombora / kuvanga, gutwikira, kalendari, gutemagura, no gupfa.
Kuvanga / Kuvanga
Kunyerera / kuvanga ni ukuvanga ibikoresho bikomeye bya bateri ya anode na cathode neza hanyuma ukongeramo solvent kugirango ukore slurry. Kuvanga buhoro ni intangiriro yumurongo wimbere wumurongo, kandi ni intangiriro yo kurangiza gutwikira nyuma, kalendari nibindi bikorwa.
Litiyumu ya batiri ya lisiyumu igabanijwemo amashanyarazi meza ya electrode nziza. Shira ibintu bifatika, karubone ikora, kubyimbye, guhuza, kongeramo, gushonga, nibindi mubivanga mukigereranyo, Mugihe cyo kuvanga, kubona ikwirakwizwa rimwe ryimyanda-yamazi ihagarikwa kugirango ushire.
Kuvanga ubuziranenge bwiza ni ishingiro ryo kurangiza ubuziranenge bwibikorwa bizakurikiraho, bizagira ingaruka ku buryo buziguye cyangwa butaziguye imikorere y’umutekano n’imikorere y’amashanyarazi ya batiri.
Igipfukisho
Gupfundikanya ni inzira yo gutwikira ibintu byiza bifatika nibintu bibi bikora kuri aluminiyumu na feri y'umuringa, hanyuma ukabihuza hamwe na moteri ikora hamwe na binder kugirango ikore urupapuro rwa electrode. Umuti uhita ukurwaho no kumisha mu ziko kugirango ibintu bikomeye bihujwe na substrate kugirango bikore impapuro nziza za electrode nziza.
Cathode hamwe na anode
Ibikoresho bya Cathode: Hariho ubwoko butatu bwibikoresho: imiterere ya laminated, imiterere ya spinel nuburyo bwa olivine, bihuye nibikoresho bya ternary (na lithium cobaltate), lithium manganate (LiMn2O4) na fosifati ya lithium (LiFePO4).
Ibikoresho bya Anode: Kugeza ubu, ibikoresho bya anode bikoreshwa muri bateri yubucuruzi ya lithium-ion harimo ibikoresho bya karubone nibikoresho bitari karubone. Muri byo, ibikoresho bya karubone birimo anode ya grafite, niyo ikoreshwa cyane muri iki gihe, hamwe na karubone anode idahwitse, karubone ikomeye, karubone yoroshye, nibindi.; ibikoresho bitari karubone birimo anode ishingiye kuri silicon, lithium titanate (LTO) nibindi.
Nka nkingi nyamukuru yibikorwa byimbere-iherezo, ubwiza bwibikorwa byo gutwikira bigira ingaruka zikomeye kumurongo, umutekano nubuzima bwa bateri yarangiye.
Kalendari
Electrode isize irushijeho gukusanyirizwa hamwe na roller, kugirango ibintu bikora hamwe nuwabikusanyije bahuze cyane, bigabanye intera yimodoka ya electron, bigabanya umubyimba wa electrode, byongera ubushobozi bwo gupakira. Muri icyo gihe, irashobora kugabanya imbaraga zimbere za bateri, kongera umuvuduko, no kunoza igipimo cyo gukoresha amajwi ya bateri kugirango yongere ubushobozi bwa bateri.
Uburinganire bwa electrode nyuma yo gutanga kalendari bizagira ingaruka kuburyo butaziguye. Uburinganire bwibintu bikora bya electrode nabyo bizagira ingaruka ku buryo butaziguye imikorere ya selile.
Kunyerera
Kunyerera ni ugukomeza kuramba gukata amashanyarazi yagutse mo ibice bigufi by'ubugari bukenewe. Mugucamo, electrode ihura nigikorwa cyo gukata hanyuma igacika, Kuringaniza kumpera nyuma yo kunyerera (nta burr na flexing) nurufunguzo rwo gusuzuma imikorere.
Inzira yo gukora electrode ikubiyemo gusudira tab ya electrode, gushiraho impapuro zifata ibyuma birinda, kuzinga tab ya electrode no gukoresha laser kugirango ugabanye tab ya electrode kugirango ikurikirane. Gupfa gupfa ni ugushiraho kashe no gushiraho electrode isize kugirango ikurikirane.
Bitewe nibisabwa cyane kuri bateri ya lithium-ion imikorere yumutekano, ubunyangamugayo, ituze hamwe nogukoresha ibikoresho birasabwa cyane mubikorwa byo gukora batiri ya lithium.
Nkumuyobozi mubikoresho byo gupima lithium electrode, Dacheng Precision yatangije urukurikirane rwibicuruzwa byo gupima electrode mugikorwa cyanyuma cyo gukora bateri ya lithium, nka X / β-ray yerekana ubucucike bwikigereranyo, uburebure bwa CDM hamwe nuburinganire bwikigereranyo, uburebure bwa laser nubundi.
- Igipimo cyiza cya X-Ray
Irashobora guhuzwa no gupima uburebure bwa mm 1600 z'ubugari, igashyigikira scanne yihuta cyane, kandi ikanamenya ibintu birambuye nko kunanura, gushushanya, no kumpera zubutaka. Irashobora gufasha gufunga-gufunga.
- Igipimo cya X / β-ray
Ikoreshwa muri bateri ya electrode yo gutwikira hamwe no gutandukanya ceramic ceramic kugirango ikore igeragezwa kumurongo wubucucike bwibice byapimwe.
- Ubunini bwa CDM & igipimo cy'ubucucike
Irashobora gukoreshwa muburyo bwo gutwikira: gutahura kumurongo wibintu birambuye bya electrode, nkibikoresho byabuze, kubura ibikoresho, gushushanya, umubyimba wibice byoroheje, gutahura umubyimba wa AT9, nibindi.;
- Sisitemu yo kugenzura ibintu byinshi
Ikoreshwa muburyo bwo gutwika cathode na anode ya bateri ya lithium. Ikoresha ama scanne menshi yo gukora kugirango ikore ibipimo bikurikirana kuri electrode. Sisitemu yo gupima ibipimo bitanu ikurikirana irashobora kugenzura firime itose, umubare wuzuye, hamwe na electrode.
- Igipimo cya Laser
Ikoreshwa mugushakisha electrode mugikorwa cyo gutwikira cyangwa kalendari ya bateri ya lithium.
- Uburebure butari kumurongo & igipimo
Ikoreshwa mukumenya ubunini nubunini bwa electrode mugikorwa cyo gutwikira cyangwa kalendari ya bateri ya lithium, itezimbere imikorere kandi ihamye.
