Indlela yokuthuthukisa ukuphepha nokuphila kwesevisi yebhethri ye-lithium-ion yebhethri ye-lithium? Ngesikhathi sokusebenzisa amabhethri e-lithium-ion, kunenkinga evame ukuhlupha abathengi bethu. Ukuphepha kwamabhethri e-lithium-ion. Uma ibhethri lethu le-lithium-ion lingathembekile, asikwazi ukulisebenzisa ngokuzethemba.

Ngokusho kwemvelo yokusetshenziswa, ukusetshenziswa kwamasu amabhethri e-lithium-ion ngesikhathi, ngakolunye uhlangothi, ukuphepha kwebhethri ye-lithium-ion kungaqinisekisa nokusebenza kwebhethri ye-lithium ion nokuphila. Ungakuthuthukisa kanjani ukuphepha kwebhethri ye-lithium-ion yebhethri ye-lithium? 1. Isixazululo sezinto ezingezinhle ze-electrode sizohlukanisa ngokuphelele usayizi wezinhlayiyana ezinkulu kanye nempushana ye-ultrafine kusayizi wezinhlayiyana ezidingekayo, ukuvimbela ukusabela kwe-electrochemical yendawo ekubeni nobudlova kakhulu futhi okungalungile nokubi, futhi kuthuthukise ukuphepha kwebhethri ye-lithium.

Thuthukisa i-porosity ebusweni bezinto ezibonakalayo, lokhu kungakhuphula umthamo we-10%, kuyilapho i-C / A ihlala njalo, ukuphepha kuthuthukiswa kakhulu. Umphumela wesixazululo unokuhambisana kangcono nobuso bezinto ezingezinhle ze-electrode ku-electrolyte, okuye kwabangela ukwakheka nokuzinza kwefilimu ye-SEI. 2.

Ukulawula inqubo ye-pulping yezinqubo ze-pulping usebenzisa izindlela zenqubo ethuthukisiwe kanye nama-reagents amakhemikhali akhethekile, ukuze kuncishiswe ukungezwani kwendawo phakathi kwamaqembu we-slurry emihle nengalungile. Thuthukisa ukuhambisana phakathi kwamaqembu, ukuvimbela okokusebenza kunqubo yokuyaluza "ukuhlangana". Igebe lezinto ezisekelwe esikhathini sokumboza kanye nombhobho kufanele lilawulwe ngaphansi kuka-0.

2 mm, engenazo izinhlayiya, ukudangala, imihuzuko efana nobuso bepuleti. I-slurry kufanele igcinwe isikhathi esingaphezu kwamahora angu-6, i-viscosity ye-slurry izinzile, futhi ingaphakathi le-slurry ayinakho ukuzenzela. I-slurry evamile iqinisekisa isilinganiso sokusatshalaliswa kwe-electrode emihle nengalungile, ngaleyo ndlela kuthuthukiswe ukungaguquguquki, ukuphepha kwebhethri ye-lithium.

3. Imishini yokukhiqiza izigxobo ethuthukisiwe ingaqinisekisa ukuzinza nokuvumelana kwekhwalithi yezingcezu, ithuthukise kakhulu ukuthengiswa kwebhethri, futhi inciphise ukuvela kwebhethri ye-lithium engaphephile. Inani lephutha lokuminyana eliphezulu lomshini wokumboza ipuleti elilodwa le-chip kufanele libe ngaphansi kuka-± 2%, ubude bobude bepuleti kanye nephutha losayizi wegebe kufanele libe ngaphansi kuka-2 mm.

I-roller shaft taper kanye ne-radial beat akufanele ibe ngaphezu kuka-4 μm, ukuze ukuvumelana kobukhulu bepuleti kuqinisekiswe. Imishini kufanele ifakwe uhlelo lwe-vacuum yomsindo ukuvimbela i-micro-teleconcopying yamaseli okubangelwa izinhlayiya ezintantayo, ngaleyo ndlela kuqinisekiswe ukusebenza kokuzikhipha kwebhethri ye-lithium. Ungayithuthukisa kanjani impilo yebhethri ye-lithium-ion yebhethri ye-lithium? ● I-short circuit i-short-circuited ku-anti-blocking, okuyinkinga enkulu ethinta ukuphepha kwebhethri ye-lithium ion.

Ngenxa yesifunda esifushane ebhethri ye-lithium-ion okubangelwa amakristalu adluliselwe i-lithium, izinto ezeqile, kuvame ukubangela izinkinga ezinkulu zokuphepha. Ukuze kuxazululwe isigameko sangaphakathi sesifunda esifushane esibangelwa ukukhula kwegatsha le-lithium, abantu baye baklama izindlela ezihlukahlukene zokuqapha ukukhula kwamabhethri e-lithium-ion. ● Ukuzilungisa okuhlakaniphile Ngokuduma kwamabhethri e-lithium-ion, ithuba lokulimala okuhlukahlukene kwebhethri le-lithium-ion nalo lisha, uma ibhethri ye-lithium-ion ikwazi ukubona umsebenzi wokuzilungisa njengezinto eziphilayo, lokhu mayelana nokwelula amabhethri e-lithium ion Ukuphila kwesevisi, ukunciphisa izingozi zokuphepha zamabhethri e-lithium-ion kunencazelo ebaluleke kakhulu.

● Umsebenzi wepuleti lokuvikela lebhethri le-lithium-ion libalulekile ukuze kuvikelwe amaseli ebhethri ebhethri elishajayo, ukugcina ukuphepha nokuzinza ekushajweni kwebhethri nenqubo yokukhipha, futhi idlala isidingo senjongo ebalulekile yokusebenza kwalo lonke uhlelo lokujikeleza kwebhethri. Abakhiqizi bebhethri ye-lithium-ion kufanele bathuthukise ukuphepha kwamabhethri e-lithium-ion, abakhiqizi besistimu ye-BMS, ukuze baqonde ukusebenza kwebhethri, ngokusekelwe kumgomo womklamo wokuphepha webhethri ye-lithium yamandla, futhi ngendlela efanele Ukusebenzisa kuyisithiyo sokugcina sokuqinisekisa ukuphepha kwebhethri. .
