Isantya sokubuyela umva: ukubuyela umva ngokubanzi yi-2-3 μm

Ukwandiswa: Iphepha le-electrode elihle ngokubanzi liyi-≈1.002

Emva kokuba igqityiwe i-electrode roll, inyathelo elilandelayo kukwahlula yonke i-electrode piece ibe yimicu emincinci enobubanzi obufanayo (ehambelana nokuphakama kwebhetri). Xa usika, qwalasela ii-burrs ze-pole piece. Kubalulekile ukuhlola ngokupheleleyo iziqwenga ze-pole ze-burrs kwizikhokelo ze-X kunye ne-Y ngoncedo lwezixhobo ezinemilinganiselo emibini. Inkqubo yobude be-burr ende Y≤1/2 H ubukhulu be-diaphragm. Ubushushu be-ambient ye-workshop kufuneka bube yi-≤23℃, kwaye i-dew point kufuneka ibe yi-≤-30℃. Inkqubo yokuvelisa amaphepha e-electrode angalunganga kwii-electrode sheets ze-lithium battery negative iyafana neyee-electrodes ezithandekayo, kodwa uyilo lwenkqubo lwahlukile. Ubushushu be-ambient ye-workshop kufuneka bube yi-≤23℃ kwaye ukufuma kufuneka kube yi-≤25%. Uxinano lokwenyani lwezinto eziqhelekileyo ze-electrode engalunganga:

Ukuxinana kwe-electrode engalunganga esetyenziswa rhoqo: Irebound rate: I-General rebound 4-8um Elongation: I-Positive plate ngokubanzi ≈ 1.002 Inkqubo yokuvelisa i-lithium battery positive electrode stripping ifana ne-positive electrode stripping process, kwaye zombini kufuneka zilawule ii-burrs kwicala le-X nele-Y. Ubushushu obuphakathi kwendawo yokusebenza kufuneka bube yi-≤23℃, kwaye i-dew point kufuneka ibe yi-≤-30℃. Emva kokuba i-positive plate ilungele ukukhutshelwa, i-positive plate kufuneka yomiswe (120°C), kwaye emva koko iphepha le-aluminium lifakwe i-weld kwaye lipakishwe. Ngexesha lale nkqubo, ubude bethebhu kunye nobubanzi bokubumba kufuneka kuqwalaselwe. Ukuthatha uyilo lwe-**650 (njengebhetri ka-18650) njengomzekelo, uyilo olunee-tabs eziveziweyo lujolise kakhulu ekuqwalaseleni intsebenziswano efanelekileyo yee-cathode tabs ngexesha lokuwelda i-cap kunye ne-roll groove. Ukuba ii-pole tabs ziveziwe ixesha elide kakhulu, i-short circuit inokwenzeka ngokulula phakathi kwee-pole tabs kunye ne-steel shell ngexesha lenkqubo yokuqengqeleka. Ukuba i-lug imfutshane kakhulu, i-cap ayinakudityaniswa. Okwangoku, kukho iintlobo ezimbini zeentloko zokuwelda ze-ultrasonic: ezimile okwe-linear nezimile okwe-point. Iinkqubo zasekhaya zisebenzisa ikakhulu iintloko zokuwelda ezimile okwe-linear ngenxa yokuqwalasela amandla ombane agqithisileyo kunye namandla okuwelda. Ukongeza, iglu yobushushu obuphezulu isetyenziselwa ukugubungela iithebhu ze-solder, ikakhulu ukuphepha umngcipheko weesekethe ezimfutshane ezibangelwa zii-metal burrs kunye nenkunkuma yesinyithi. Ubushushu obujikeleze indawo yokusebenza kufuneka bube yi-≤23℃, i-dew point kufuneka ibe yi-≤-30℃, kwaye umxholo womswakama we-cathode kufuneka ube yi-≤500-1000ppm.

Ukulungiswa kwepleyiti engalungangaIpleyiti engalunganga kufuneka yomiswe (105-110°C), emva koko amaphepha e-nickel adityaniswe aze apakishwe. Ubude bethebhu ye-solder kunye nobubanzi bokwenza kufuneka kuqwalaselwe. Ubushushu obuphakathi kwendawo yokusebenzela kufuneka bube yi-≤23℃, i-dew point kufuneka ibe yi-≤-30℃, kwaye umxholo wokufuma we-electrode engalunganga kufuneka ube yi-≤500-1000ppm. Ukujija kukujija i-separator, i-positive electrode sheet kunye ne-negative electrode sheet zibe yi-iron core ngomatshini wokujija. Umgaqo kukujija i-positive electrode nge-negative electrode, uze wahlukanise i-positive kunye ne-negative electrodes nge-separator. Ekubeni i-negative electrode yenkqubo yendabuko yi-control electrode yoyilo lwebhetri, uyilo lomthamo luphezulu kunolo lwe-positive electrode, ukuze ngexesha lokutshaja kokwakheka, i-Li+ ye-positive electrode inokugcinwa "kwisithuba" se-electrode engalunganga. Ingqwalasela ekhethekileyo kufuneka ihlawulwe kwi-winding tension kunye ne-pole piece arrangement xa ijija. Ukujija okuncinci kakhulu kuya kuchaphazela ukumelana kwangaphakathi kunye nesantya sokufakwa kwezindlu. Uxinzelelo olugqithisileyo lunokukhokelela kumngcipheko we-short circuit okanye i-chip. Ulungelelwaniso lubhekisa kwindawo ehambelanayo ye-electrode engalunganga, i-electrode echanekileyo, kunye ne-separator. Ububanzi be-electrode engalunganga yi-59.5 mm, i-electrode echanekileyo yi-58 mm, kwaye i-separator yi-61 mm. Ezi zintathu zilungelelaniswe ngexesha lokudlala ukuze kuthintelwe umngcipheko we-short circuits. Uxinzelelo lwe-winding luqhele ukuba phakathi kwe-0.08-0.15Mpa kwi-posi echanekileyo, i-0.08-0.15Mpa kwi-posi engalunganga, i-0.08-0.15Mpa kwi-diaphragm ephezulu, kunye ne-0.08-0.15Mpa kwi-diaphragm esezantsi. Uhlengahlengiso oluthile luxhomekeke kwizixhobo kunye nenkqubo. Ubushushu obujikeleze le workshop yi-≤23℃, i-dew point yi-≤-30℃, kwaye umxholo womswakama yi-≤500-1000ppm.

Ngaphambi kokuba isiseko sebhetri esinekheyisi sifakelwe kwikheyisi, kufuneka uvavanyo lweHi-Pot lwe-200 ~ 500V (ukuvavanya ukuba ibhetri ene-voltage ephezulu ifinyeziwe), kwaye kufuneka i-vacuum ukuze kulawulwe uthuli ngaphambi kokuba ifakwe kwikheyisi. Iindawo ezintathu eziphambili zokulawula iibhetri ze-lithium kukufuma, ii-burrs kunye nothuli. Emva kokuba inkqubo yangaphambili igqityiwe, faka i-gasket esezantsi ezantsi kwesiseko sebhetri, goba iphepha le-electrode elilungileyo ukuze umphezulu ujongane nomngxuma we-pinhole ojikelezayo wesiseko sebhetri, kwaye ekugqibeleni ulifake ngokuthe nkqo kwigobolondo lentsimbi okanye kwigobolondo le-aluminium. Ukuthatha uhlobo lwe-18650 njengomzekelo, ububanzi bangaphandle ≈ 18mm + ukuphakama ≈ 71.5mm. Xa indawo enqamlezileyo yesiseko senxeba incinci kunendawo engaphakathi enqamlezileyo yekheyisi yentsimbi, izinga lokufakwa kwekheyisi yentsimbi limalunga ne-97% ukuya kwi-98.5%. Ngenxa yokuba ixabiso le-rebound yentonga kunye nomlinganiselo wokungena kolwelo ngexesha lokufakwa kamva kufuneka kuqwalaselwe. Inkqubo efanayo neyomphezulu ongaphantsi komhlaba ibandakanya ukuhlanganiswa kwe-underlayment ephezulu. Ubushushu obujikeleze indawo yokusebenza kufuneka bube yi-≤23℃, kwaye iqondo lombethe libe yi-≤-40℃.

Ukuqengqelekaifaka iphini yesolder (edla ngokwenziwa ngobhedu okanye i-alloy) embindini wesiseko sesolder. Iiphini ze-welding ezisetyenziswa rhoqo yi-Φ2.5*1.6mm, kwaye amandla e-welding e-electrode engalunganga kufuneka abe yi-≥12N ukuze ifaneleke. Ukuba iphantsi kakhulu, iya kubangela ngokulula ukunyibilika okubonakalayo kunye nokumelana okugqithisileyo kwangaphakathi. Ukuba iphezulu kakhulu, kulula ukunyibilikisa umaleko we-nickel kumphezulu wegobolondo lentsimbi, okubangela amalungu e-solder, okukhokelela kwiingozi ezifihlakeleyo ezifana nokugqwala kunye nokuvuza. Ukuqonda okulula kwe-rolling groove kukulungisa umongo webhetri yenxeba kwi-casing ngaphandle kokushukuma. Kwinkqubo yokuvelisa le bhetri ye-lithium, kufuneka kuqwalaselwe ngokukodwa ukufanisa isantya se-transverse extrusion kunye nesantya sokucinezela eside ukuze kuthintelwe ukusika i-casing ngesantya esiphezulu se-transverse, kwaye umaleko we-nickel we-notch uya kuwa ukuba isantya se-longitudinal sikhawuleza kakhulu okanye ukuphakama kwe-notch kuya kuchaphazeleka kwaye ukutywinwa kuya kuchaphazeleka. Kubalulekile ukujonga ukuba amaxabiso enkqubo yobunzulu be-groove, ulwandiso kunye nokuphakama kwe-groove ayahambelana nemigangatho (ngokubalwa okusebenzayo kunye nokwethiyori). Ubungakanani obuqhelekileyo besitovu yi-1.0, 1.2 kunye ne-1.5 mm. Emva kokuba umngxuma oqengqelekayo ugqityiwe, umatshini wonke kufuneka uphinde ucocwe nge-vacuum ukuze kuthintelwe inkunkuma yesinyithi. Iqondo le-vacuum kufuneka libe yi-≤-0.065Mpa, kwaye ixesha lokucoca nge-vacuum kufuneka libe yi-1 ~ 2s. Iimfuno zobushushu obuphakathi kwale workshop ziyi-≤23℃, kwaye inqanaba lombethe liyi-≤-40℃. Ukubhaka kwebhetri core Emva kokuba amaphepha ebhetri esilinda eqengqwe kwaye egobile, inkqubo elandelayo yokuvelisa ibhetri ye-lithium ibaluleke kakhulu: ukubhaka. Ngexesha lokuveliswa kweeseli zebhetri, kungeniswa ubungakanani obuthile bomswakama. Ukuba umswakama awunakulawulwa ngaphakathi koluhlu oluqhelekileyo ngexesha, ukusebenza kunye nokhuseleko lwebhetri kuya kuchaphazeleka kakhulu. Ngokubanzi, i-oven ye-vacuum ezenzekelayo isetyenziselwa ukubhaka. Lungisa iiseli eziza kubhakwa kakuhle, faka i-desiccant kwi-oven, usete iiparameter, kwaye unyuse ubushushu bube yi-85°C (uthatha iibhetri ze-lithium iron phosphate njengomzekelo). Oku kulandelayo yimigangatho yokubhaka yeenkcukacha ezahlukeneyo zeeseli zebhetri:

Inaliti yolweloInkqubo yokwenziwa kwebhetri ye-lithium ibandakanya uvavanyo lokufuma kweeseli zebhetri ezibhakiweyo. Kuphela emva kokufikelela kwimigangatho yokubhaka yangaphambili apho ungaqhubeka khona ukuya kwinqanaba elilandelayo: ukufaka i-electrolyte. Faka iibhetri ezibhakiweyo ngokukhawuleza kwibhokisi yeglavu ye-vacuum, ulinganise kwaye ubhale phantsi ubunzima, ubeke kwikomityi yenaliti, kwaye wongeze ubunzima obuyilwe yi-electrolyte kwikomityi (ngesiqhelo kwenziwa uvavanyo lwebhetri olufakwe ulwelo: faka ibhetri kwikomityi embindini). Faka isiseko sebhetri kwi-electrolyte, uyicwilise ixesha elithile, vavanya amandla aphezulu okufunxa ulwelo lwebhetri (ngesiqhelo uzalise ulwelo ngokwevolumu yovavanyo), uyibeke kwibhokisi ye-vacuum ukuze uvacuum (i-vacuum degree ≤ -0.09Mpa), kwaye ukhawulezise ukungena kwe-electrolyte kwi-electrode. Emva kwemijikelo eliqela, susa iziqwenga zebhetri uze uzilinganise. Bala ukuba umthamo wenaliti uyahlangabezana na nexabiso loyilo. Ukuba incinci, kufuneka izaliswe kwakhona. Ukuba ininzi kakhulu, galela nje okungaphezulu ude uhlangabezane neemfuno zoyilo. Indawo yebhokisi yetligi ifuna ubushushu ≤23℃ kunye ne-dew point ≤-45℃.

UkuweldaNgexesha lenkqubo yokwenziwa kwebhetri ye-lithium, isigqubuthelo sebhetri kufuneka sibekwe kwibhokisi yeglavu kwangaphambili, kwaye isigqubuthelo sebhetri kufuneka sinamathele kwisikhunta esisezantsi somatshini we-super welding ngesandla esinye, kwaye umongo webhetri kufuneka ubanjwe ngesinye isandla.
