iibhetri ze ithium-ion zinoluhlu olubanzi lwezicelo. Ngokutsho kokuhlelwa kweendawo zesicelo, inokwahlulwa ibe yibhetri yokugcina amandla, ibhetri yamandla kunye nebhetri ye-electronics yabathengi.
- Ibhetri yokugcina amandla iquka ukugcinwa kwamandla onxibelelwano, ukugcinwa kwamandla ombane, iinkqubo zamandla ezisasazwayo, njl.;
- Ibhetri yamandla isetyenziswa kakhulu kwintsimi yamandla, ukukhonza imarike kuquka izithuthi zamandla amatsha, iiforklift zombane, njl.;
- Ibhetri ye-elektroniki yabathengi igubungela umthengi kunye necandelo lemizi-mveliso, kubandakanya nemitha ehlakaniphile, ukhuseleko lobukrelekrele, uthutho lobukrelekrele, i-Intanethi yeZinto, njl.
Ibhetri ye-Lithium-ion yinkqubo enzima, ngokukodwa eyenziwe nge-anode, i-cathode, i-electrolyte, i-separator, umqokeleli wangoku, i-binder, i-agent eqhubayo njalo njalo, ebandakanya ukuphendula okubandakanya ukusabela kwe-electrochemical ye-anode kunye ne-cathode, i-lithium ion conduction kunye ne-electronic conduction, kunye nokusabalalisa ukushisa.
Inkqubo yokuvelisa iibhetri ze-lithium zide, kwaye iinkqubo ezingaphezu kwe-50 zibandakanyeka kwinkqubo.
Iibhetri zeLithium zinokwahlulwa zibe ziibhetri zecylindrical, iibhetri ze-aluminiyam zesikwere, iibhetri zesingxobo kunye neebhetri zeblade ngokwefomu. Kukho iiyantlukwano kwinkqubo yabo yokuvelisa, kodwa ngokubanzi inkqubo yokuvelisa ibhetri ye-lithium inokwahlulwa ibe yinkqubo ye-front-end (imveliso ye-electrode), inkqubo yenqanaba eliphakathi (i-cell synthesis), kunye nenkqubo yomva (ukwakheka kunye nokupakishwa).
Inkqubo yangaphambili yokwenziwa kwebhetri ye-lithium iya kwaziswa kweli nqaku.
Injongo yemveliso yenkqubo yangaphambili kukugqiba ukuveliswa kwe-electrode (i-anode kunye ne-cathode). Inkqubo yayo ephambili ibandakanya: i-slurrying / ukuxuba, i-coating, i-calendering, i-slitting, kunye nokusika ukufa.
Ukutyibilika/Ukuxuba
Ukutyibilika/ukuxuba kukuxuba imathiriyeli eyomeleleyo yebhetri ye anode kunye necathode ngokulinganayo uze wongeze isinyibilikisi ukwenza uludaka. Ukuxutywa kwe-slurry kukuqala kwesiphelo sangaphambili somgca, kwaye kusisandulela sokugqitywa kwe-coating elandelayo, i-calendering kunye nezinye iinkqubo.
Udaka lwebhetri yeLithium lwahlulwe lube ludaka lwe-electrode olulungileyo kunye nodaka olubi lwe-electrode. Faka izinto ezisebenzayo, i-carbon conductive, i-thickener, i-binder, i-additive, i-solvent, njl.
Ukuxubana komgangatho ophezulu kusisiseko sokugqitywa komgangatho ophezulu wenkqubo elandelayo, eya kuchaphazela ngokuthe ngqo okanye ngokungathanga ngqo ukusebenza kokhuseleko kunye nokusebenza kwe-electrochemical yebhetri.
Ukwaleka
Ukwaleka yinkqubo yokugquma izinto ezintle ezisebenzayo kunye nezinto ezingalunganga ezisebenzayo kwi-aluminium kunye neefoyile zobhedu ngokulandelelana, kunye nokudibanisa kunye ne-conductive agents kunye ne-binder ukwenza i-electrode sheet. I-solvents emva koko isuswe ngokumisa kwi-oven ukuze into eqinileyo idibaniswe kwi-substrate ukwenza ikhoyili yephepha le-electrode elungileyo kunye nengalunganga.
Cathode kunye nokwaleka anode
Izinto zeCathode: Kukho iintlobo ezintathu zezinto eziphathekayo: isakhiwo se-laminated, isakhiwo se-spinel kunye nesakhiwo se-olivine, esihambelana nezixhobo ze-ternary (kunye ne-lithium cobaltate), i-lithium manganate (i-LiMn2O4) kunye ne-lithium iron phosphate (LiFePO4) ngokulandelanayo.
Izinto ze-Anode: Okwangoku, izinto ze-anode ezisetyenziselwa ibhetri ye-lithium-ion yorhwebo ikakhulu ziquka izinto zekhabhoni kunye nezinto ezingezona carbon. Phakathi kwazo, izinto zekhabhoni ziquka i-graphite anode, eyona nto isetyenziswa kakhulu ngoku, kunye ne-disordered carbon anode, i-carbon carbon, i-soft carbon, njl.; izinto ezingekho carbon ziquka anode silicon-based, lithium titanate (LTO) njalo njalo.
Njengoko ikhonkco eliphambili lenkqubo ye-front-end, umgangatho wokwenziwa kwenkqubo yokugqoka ichaphazela kakhulu ukuhambelana, ukhuseleko kunye nomjikelezo wobomi bebhetri egqityiweyo.
Ikhalenda
I-electrode edibeneyo idityaniswe ngakumbi nge-roller, ukwenzela ukuba i-substance esebenzayo kunye nomqokeleli basondelene ngokusondeleyo, ukunciphisa umgama wokuhamba kwee-electron, ukunciphisa ubukhulu be-electrode, ukwandisa umthamo wokulayisha. Kwangaxeshanye, inokuthoba ukuxhathisa kwangaphakathi kwebhetri, yandise i-conductivity, kwaye iphucule izinga lokusetyenziswa kwebhetri ukuze kwandiswe umthamo webhetri.
I-flatness ye-electrode emva kwenkqubo ye-calendering iya kuchaphazela ngokuthe ngqo umphumo wenkqubo yokuqhawula okulandelayo. Ukufana kwezinto ezisebenzayo ze-electrode kuya kuchaphazela ngokungathanga ngqo ukusebenza kweeseli.
Ukusika
I-Slitting yi-longitudinal cutting eqhubekayo yekhoyili ye-electrode ebanzi ibe ngamaqhekeza amancinci obubanzi obufunekayo. Kwi-slitting, i-electrode idibana nesenzo sokucheba kwaye iphule, I-flatness edge emva kokuqhawula (akukho burr kunye ne-flexing) isitshixo sokuhlola ukusebenza.
Inkqubo yokwenza i-electrode ibandakanya ithebhu ye-electrode ye-welding, ukusebenzisa iphepha lokunamathela elikhuselayo, ukugoqa ithebhu ye-electrode kunye nokusebenzisa i-laser ukusika ithebhu ye-electrode kwinkqubo yokugoqa elandelayo. I-Die-cutting kukusitampu kunye nokubumba i-electrode egqunyiweyo kwinkqubo elandelayo.
Ngenxa yeemfuno eziphezulu zokusebenza kweebhetri ze-lithium-ion, ukuchaneka, ukuzinza kunye nokuzenzekelayo kwezixhobo zifunwa kakhulu kwinkqubo yokuvelisa ibhetri ye-lithium.
Njengomkhokeli kwizixhobo zokulinganisa i-lithium electrode, i-Dacheng Precision iye yasungula uluhlu lweemveliso zokulinganisa i-electrode kwi-front-end process ye-lithium ibhetri yokuvelisa, njenge-X / β-ray ye-areal density gauge, ubukhulu be-CDM kunye ne-areal density gauge, i-laser thickness gauge njalo njalo.
