Ukukhetha umatshini ofanelekileyo wokugquma ibhetri yeLithium-Ion
Intshayelelo
Kwimveliso yeebhetri ze-lithium-ion, umgangatho we-electrode umisela ngokuthe ngqo ukusebenza kwebhetri kunye nokusebenza kakuhle kwemveliso. Nangona kunjalo, abavelisi badla ngokujongana nemingeni efana nokungangqinelani kwengubo, ukusebenza okuphantsi, kunye namazinga aphezulu eziphene.
Ukusombulula ezi ngxaki, oomatshini bokugquma baye baba zizixhobo ezibalulekileyo kwimigca yemveliso yebhetri yanamhlanje.
Yintoni umatshini wokugquma?
Umatshini wokugquma usetyenziselwa ukufaka udaka kwi-aluminium okanye kwi-copper foil ukwenza ii-electrode zebhetri. Usetyenziswa kakhulu kwezi zinto zilandelayo:
- Iibhetri zamandla ze-EV
- Iinkqubo zokugcina amandla (ESS)
- Iibhetri ze-lithium-ion zabathengi
Le yenye yezona nyathelo zibalulekileyo ekuvelisweni kwee-electrode.
Kutheni Ukwaleka Kubaluleke Kangaka? (Amanqaku Entlungu Kwishishini)
- Ukwaleka okungalinganiyo kukhokelela ekusebenzeni kwebhetri okungalinganiyo
- Iziphene ezifana namaqamza kunye nemifantu zinciphisa isivuno
- Imigca yesiqhelo yokugquma isebenza kwi-80–100 m/min, nto leyo ethintela ukusebenza kakuhle kwemveliso enkulu.
- Inkunkuma yezinto eziphathekayo inyusa iindleko zokuvelisa
Izisombululo Eziqhelekileyo Zokugquma
1. Ukwaleka kwe-Extrusion (Slot Die)
- Ukuchaneka okuphezulu
- Ifanelekile kwimveliso ekhawulezayo
2. Ukwaleka ngeGravure
- Isetyenziselwa ukugqoka i-primer
- Isebenza kakuhle emalini
3. Ukwaleka okwahluliweyo
- Iphucula ukusebenza kokhuseleko
Kutheni Ukwaleka Kwamacala Amabili Kuqala Ukuba Yinto Eqhelekileyo
Xa kuthelekiswa nokwaleka kwicala elinye, ukwaleka kwicala elinye kunika:
- Ukuphuculwa kokusebenza kakuhle kwemveliso malunga nama-60–80% kwiindawo zokuvelisa eziqhubekayo
- Ukuzinza okungcono
- Ixabiso eliphantsi
Kubaluleke ngakumbi kwimveliso enkulu yebhetri.
Isisombululo Esicetyiswayo: I-Double-Layer High-Speed Extrusion Coater
Ukuze bahlangabezane nezi mfuno, abavelisi abaphambili bamkela oomatshini bokugquma abasebenzisa isantya esiphezulu abaphindwe kabini.
Kwimveliso yeebhetri ezikhawulezayo nezinkulu, abavelisi badla ngokwamkela iinkqubo zokugquma ezidityanisiweyo eziphuhliswe ngababoneleli abanjengoPengjin, ingakumbi kwiiprojekthi zenqanaba le-gigafactory ezifuna ukuchaneka kunye nokusebenza kakuhle.
Ezona mpawu:
- Khawulezisa ukuya kuthi ga 160 m/ngomzuzu, okuvumela ukuveliswa okuphezulu
- Uxinano olumacala amabini ≤ ±1.0%
- Ulawulo loxinzelelo ≤ ±2N
- Ulungelelwaniso ≤ ±0.5 mm
Kwiinguqulelo ezisebenzayo, abanye abavelisi beebhetri baxele ukuba ukusebenza kakuhle kuphuculwe ngaphezu kwe-30% emva kokutshintsha ukusuka kwiinkqubo zokugquma eziqhelekileyo ukuya kwizisombululo zokukhupha eziphindwe kabini, kunye nokunciphisa inkunkuma yezinto eziphathekayo.
Imizekelo yesicelo
- Iifektri ezinkulu zebhetri ye-EV
- Imigca yemveliso yokugcina amandla
- Ukuveliswa kweebhetri zabathengi
- Imigca yovavanyo lwe-R&D
Isiphelo
Kwimveliso yebhetri ye-lithium, oomatshini bokugquma abangoovimba nje kuphela kodwa bakwayinto ephambili ekumiseleni ukhuphiswano lokuvelisa.
Ngenxa yemfuno ekhulayo yokusebenza kakuhle kunye nokuhambelana, izisombululo zokugquma ezinesantya esiphezulu ezimacala mabini ziyanda ukwamkelwa ngabavelisi abaphambili.
Ukuba usebenza kwiprojekthi entsha yebhetri okanye ulungisa umgca wemveliso okhoyo, ukuqonda isisombululo esifanelekileyo sokugquma kunokwenza umahluko omkhulu. Ukuphonononga ubuchwepheshe obukhoyo kunye nokubonisana nababoneleli bezixhobo abanamava kunokukunceda wenze isigqibo esinolwazi oluthe kratya.
