Mashandiro Anoita Mabhatiri Akadzokororwa
Kukurudzira kushandiswa kwesimba rakachena kwakaona kuwedzera kukuru kwekushandiswa kwemabhatiri—kubva kunharembozha nemalaptop kusvika kumotokari dzemagetsi uye kuchengetwa kwesimba guru. Asi pasinei nemabhenefiti awo, mabhatiri anokonzerawo matambudziko ezvakatipoteredza: zvinhu zvishoma, utsi hunobva mumigodhi, uye njodzi yemarara ane njodzi kana akaraswa zvisina kunaka. Apa ndipo panotanga kushanda pfungwa yemabhatiri akadzokororwa. Mabhatiri akadzokororwa haasi mabhatiri "akamboshandiswa", asi chikamu chehurongwa hwakatenderera hunodzosera zvinhu zvinokosha kune cheni yekugovera. Saka, mabhatiri akadzokororwa anoshanda sei chaizvo?
Chii chinonzi Bhatiri Rinodzokororwa?
Izwi rekuti "bhatiri rakadzokororwa" rinowanzoreva zvinhu zviviri. Chekutanga, mabhatiri akagadzirwa nezvinhu zvakadzokororwa, zvakaita senickel, cobalt, lithium, manganese, graphite, copper, uye aruminiyamu zvakatorwa kubva kumabhatiri akamboshandiswa. Chechipiri, mabhatiri akagadzirirwa kudzokororwa zviri nyore, zvakaita sekushandisa magadzirirwo emodular, tambo dzinobviswa zviri nyore, uye mavara emakemikari akajeka. Mukuita kwemaindasitiri, chinangwa chikuru ndechekugadzira jira rakavharwa: mabhatiri akamboshandiswa anogadziriswa, zvinhu zvawo zvinodzokororwa, uye ozoshandiswazve kugadzira masero matsva emabhatiri.
Sei Mabhatiri Achifanira Kudzokorodzwa?
Mabhatiri—kunyanya mabhatiri e lithium-ion—ane zvinhu zvinokosha uye zvinogona kuva nengozi. Kudzokorodza kwakakosha nekuti:
1. Deredza kucherwa kwematombo: Kudzoserwa kwe nickel, cobalt, uye lithium kunogona kuderedza kudiwa kwekucherwa kutsva.
2. Deredza kukanganiswa kwekabhoni: Kugadzirwa kwezvinhu zvisina kugadzirwa kubva mumigodhi kunowanzo da simba rakawanda.
3. Kudzivirira kusvibiswa: Maelectrolyte nemamwe macompound anogona kuva nengozi kana akadonhera muvhu kana mumvura.
4. Kuchengetedzeka: Mabhatiri akamboshandiswa anogona kuchengetedza simba uye ari panjodzi yekukundikana kushanda kana kubatira moto kana akasashandiswa zvakanaka.
5. Kuchengetedzwa kwezvekushandisa: Nyika kana maindasitiri anogona kuderedza kuvimba kwavo nezvinhu zvakagadzirwa kubva kunze kwenyika.
Nemamwe mashoko, mabhatiri akadzokororwa "anoshanda" senzvimbo yekuwana zvinhu zvitsva, kwete marara chete.
Danho 1: Kuunganidza uye Kuronga
Maitiro acho anotanga nekuunganidzwa kwemabhatiri akamboshandiswa kuburikidza nenzvimbo dzekudzokorodza, mapurogiramu ekugadzira mota, nzvimbo dzekugadzirisa mota dzemagetsi, kana nzvimbo dzekugadzirisa marara emagetsi. Kana angounganidzwa, mabhatiri anofanira kurongwa, sezvo asiri ese mabhatiri akaenzana. Anouya mumakemikari akasiyana: LFP (lithium iron phosphate), NMC (nickel manganese cobalt), NCA, LCO, nezvimwewo. Kuronga kwakakosha nekuti mhando yega yega inoda nzira yakasiyana yekudzoreredza uye ine kukosha kwakasiyana kwezvinhu.
Panguva ino, nzvimbo yacho inowanzoongorora:
– Rudzi rwebhatiri (cylindrical, pouch, prismatic, vehicle module)
– Mamiriro emuviri (akakuvara, akazvimba, akatsva)
- Kuchengetedzwa kwenyika
- Ruzivo rwezita rebhatiri kana data reBMS (Battery Management System) pabhatiri remotokari
Danho rechipiri: Kuita kuti bhatiri rive rakachengeteka (kuburitsa uye kugadzikana)
Mabhatiri asati abviswa, anowanzo bviswa kuti aderedze njodzi yekuchinja kwemagetsi nemoto. Kune mabhatiri emotokari dzemagetsi, mamodule kana mapaketi anogona kunge aine voltage yakakwira, zvichida nzira dzakakosha dzekuchengetedza nemidziyo.
Mushure mezvo, kugadzikana kunoitwa, semuenzaniso uchishandisa nzvimbo isina chinhu, kutonhora, kana nzira dzekubata dzinodzivirira electrolyte kuti isashande nemhepo. Chinangwa chikuru ndechekuona kuti bhatiri rakachengeteka pakupatsanurwa uye kugadziriswa kwemuchina.
Danho rechitatu: Kuputsa
Kubvisa zvinhu kunogona kuitwa nemaoko, nehafu otomatiki, kana otomatiki. Mumabhatiri emotokari emagetsi, paki yacho inovhurwa kuti iparadzaniswe:
- Kesi uye chimiro (simbi, aruminiyamu)
– Tambo nemabhazi (mhangura/aruminiyamu)
- Sisitimu yekutonhodza uye zvikamu zvemagetsi
- Mamodule nemasero
Kupatsanura zvakanaka kunovandudza mashandiro ekugadzirisa zvinhu uye kunoderedza kusvibiswa kwechinhu. Zvisinei, kupatsanura kwakaomawo nekuti magadzirirwo emabhatiri akasiyana kubva kune vagadziri uye anowanzo shandisa manamati kana welds zvakaoma kubvisa.
Danho rechina: Kugadziriswa kweMichina uye Kugadzirwa kwe "Black Mass"
Mushure mekunge mabhatiri abatwa, danho rinotevera nderekugadzirisa michina senge:
– Kucheka (kucheka) mumamiriro ezvinhu akarongwa
- Kuparadzanisa saizi yechinhu chinovharirwa uye saizi yechinhu
- Kupatsanurwa kwemagineti kune simbi yakasiyana
- Kupatsanura kwemhepo kuti kupatsanure zvikamu zvechiedza
- Kupatsanurwa kwehuwandu hwemhangura nearuminiyamu
Chinhu chikuru chechikamu ichi iblack mass, musanganiswa weupfu wakapfuma mune active cathode/anode materials. Black mass inowanzo kuve ne lithium, nickel, cobalt, manganese, graphite, uye residual electrolyte uye binder. Uyu ndiwo "mugodhi" mukuru mukushandiswazve kwemabhatiri emazuva ano.
Danho rechishanu: Kudzoreredza Zvinhu (Hydrometallurgy nePyrometallurgy)
Apa ndipo panonyanya kukosha "kuti mabhatiri akadzokororwa anoshanda sei": mabhatiri akamboshandiswa haangoshandiswizve chete, asi anopatsanurwa kuita zvinhu zvisina kugadzirwa.
1) Pyrometallurgy (Maitiro eThermal)
Nzira iyi inoshandisa tembiricha yepamusoro kunyungudutsa nekuparadzanisa simbi. Zvakanakira zvayo:
- Inotsungirira zvakanyanya musanganiswa wemakemikari ebhatiri
- Maitiro acho ari nyore padanho rekutanga rekuparadzana.
Asi pane zvimwe zvazvinokanganisa:
- Kushandiswa kwesimba rakawanda
– Zvimwe zvinhu (zvakaita se lithium nearuminiyamu) zvinogona kuguma zvaita tsvina kana kuti zvinoda mamwe matanho ekugadzirisa.
- Kusvibiswa kwemhepo kunogona kuitika kunofanira kudzorwa zvakasimba
Pyrometallurgy inowanzo gadzira simbi dzakasanganiswa (semuenzaniso dzine nickel, cobalt, mhangura) idzo dzinozogadziriswazve.
2) Hydrometallurgy (Maitiro eMakemikoro Akanyorova)
Nzira iyi inonyungudutsa simbi nhema uchishandisa mhinduro chaiyo (acid kana imwe leaching agent), wobva waparadzanisa simbi kuburikidza ne:
- kunaya kwemvura kwakasarudzwa,
- kubvisa zvinonyungudutsa,
- ion exchanger,
- kuumbwa kwekristaro.
Zvakanakira:
- Kuwanda kwemari yekutora nickel/cobalt/manganese uye inogona kugadziriswa kuti ishandiswe zvakanaka ne lithium.
- Kuchena kwechigadzirwa kunogona kunge kwakanyanya, kwakakodzera zvinhu zvitsva zve cathode
Zvakashata:
- Inogadzira marara emvura anofanira kugadziriswa
- Inoda kungwarira pakudzora maitiro
Munzvimbo dzakawanda dzemazuva ano, kugadzirwa kwemechanical + hydrometallurgy kuri kuva musanganiswa unozivikanwa nekuda kwekushanda kwayo zvakanaka.
3) Kudzokorodza Zvakananga
Maitiro aya anoedza kudzoreredza zvinhu zve cathode zvinoshanda pasina kuzviparadzanisa zvachose kuita zvinhu zvayo zvekutanga. Semuenzaniso, ma cathode "asina kusimba" anogadziriswazve (anogadziriswazve) kuti ashandiswe zvakare. Kana zvikabudirira padanho guru, kudzokorodza zvakananga kunogona:
- kuchengetedza simba,
- kuderedza danho rekuchenesa,
- kuchengetedza kukosha kwezvinhu zvinoshanda.
Zvisinei, nzira iyi inonyanya kubatwa nekusvibiswa uye kuchinja kwemakemikari, saka kushandiswa kwayo kuchiri kukura.
Danho rechitanhatu: Kuva Bhatiri Itsva Raw Material
Mushure mekunge simbi yawanikwa, indasitiri inogadzira zvigadzirwa zvepakati zvakaita se:
– nickel sulfate, cobalt sulfate, manganese sulfate (yezvinotangira cathode),
- lithium carbonate kana lithium hydroxide,
- mhangura chaiyo nearuminiyamu,
– graphite yakanatswa (mune mamwe maitiro).
Chinhu ichi chinopinda zvakare muketani yekugadzira: chinogadzirwa kuita ma precursors, active cathodes, anodes, uyezve ma battery cell matsva. Ndipo panguva iyi apo "mabhatiri akadzokororwa" anoshanda senzvimbo - zvichideredza kuvimba nekuchera nekuvhara loop yezvinhu.
Basa re "Hupenyu hwechipiri" muKudzokorodza Zvinhu Zvakatipoteredza Nderipi?
Mamwe mabhatiri asati adzokororwa, kunyanya ayo anobva mumotokari dzemagetsi, anogona kupinda muchikamu chechipiri chehupenyu. Izvi zvinoreva kuti mabhatiri ane simba rakaderera remotokari (ngatitii, ari pa70–80%) anogona kushandiswa kune zvishandiso zvisingade kushanda kwepamusoro, zvakaita se:
- kuchengetedza simba remagetsi kumba,
- simba rekuchengetedza,
- kuchengetera simba remagetsi ezuva,
- zvinoenzanisa mutoro muindasitiri.
Hupenyu hwechipiri hunowedzera hupenyu hwebhatiri, hunononotsa kudzokororwa, uye hunowedzera kukosha kwaro muhupfumi. Zvisinei, pakupedzisira, bhatiri richaramba richidzokororwa.
Matambudziko Makuru Ekugadzirisa Mabhatiri
Kunyange zvazvo zvichivimbisa, kudzokorodza mabhatiri kunosangana nematambudziko akati wandei:
- Dhizaini isina kufanana: yakaoma kupatsanura nekugadzirisa.
– Njodzi dzekuchengetedza: mabhatiri akakuvara anogona kukonzera moto.
– Kuchengetedza hupfumi hwemashandiro: kukosha kwecobalt kuri kudzikira mune mamwe ma chemistry matsva (semuenzaniso LFP), saka mabhizinesi anofanirwa kuchinjwa.
- Chiyero uye mafambiro ebasa: zvinoda hurongwa hwakanaka hwekuunganidza zvinhu uye mitemo inotsigira.
– Kuchena kwechigadzirwa: kuti chipindezve mubhatiri, chinhu chacho chinofanira kusangana nezvinodiwa zvepamusoro.
Mhinduro yacho inosanganisira hunyanzvi hwekugadzira, mitemo yeindasitiri, kuputsa otomatiki, uye mutemo wekuwedzera mutoro wemugadziri.
Mhedziso
Mabhatiri akadzokororwa anoshanda nenzira yakarongeka: anounganidzwa, anogadziriswa akachengeteka, anobviswa, anopwanywa kuita dema, uye zvinhu zvinodzokororwa kuburikidza nenzira dzinopisa, dzakanyorova, kana nzira dzekudzokorodza zvakananga. Mugumisiro wekupedzisira hausi kungoderedza marara asi zvinhu zvitsva zvekugadzira mabhatiri echizvarwa chinotevera. Nehurongwa hwekudzokorodza hwakagadzirwa zvakanaka, mabhatiri anogona kuva chikamu chehupfumi hwakatenderera - zvichideredza kukanganisa kwezvakatipoteredza uku zvichiwedzera kusimba kwekuwanikwa kwezvinhu zvakakosha kune ramangwana remagetsi.
Kana muchida, ndinogona kugadzirisa chinyorwa ichi kuti chienderane nevanhu vakanangana nacho (vadzidzi, veruzhinji, vehunyanzvi), kuwedzera data rehuwandu, kana kusanganisira bhuku remabhuku uye masosi akavimbika.
