Ezweni elincane kakhulu lamabhethri e-lithium, kukhona “umnakekeli ongabonakali” obalulekile - isihlukanisi, esibuye saziwe ngokuthi ulwelwesi lwebhethri. Isebenza njengengxenye eyinhloko yamabhethri e-lithium namanye amadivaysi e-electrochemical. Ikakhulukazi eyenziwe nge-polyethylene PE (i-polyethylene PE, i-polypropylene PP), ezinye izihlukanisi ezisezingeni eliphezulu futhi zamukela izimbotshana zobumba (isb, i-alumina) noma izinto eziyinhlanganisela ukuze kuthuthukiswe ukumelana nokushisa, kuzenze zibe yimikhiqizo yefilimu enezimbobo evamile. Ubukhona bayo busebenza “njenge-firewall” eqinile, ehlukanisa ngokomzimba ama-electrode amahle futhi angalungile ebhethri ye-lithium ukuvimbela amasekhethi amafushane, kuyilapho ngesikhathi esifanayo isebenza “njengomgwaqo onguthelawayeka we-ion,” ovumela ama-ion ukuthi ahambe ngokukhululeka futhi aqinisekise ukusebenza okujwayelekile kwebhethri.
Ukwakheka kolimi nokuqina kwesihlukanisi, imingcele ebonakala ivamile, kufihla “izimfihlo” ezijulile. I-grammage (i-areal density) yezinto ezihlukanisa ibhethri le-lithium ayibonisi nje ngokungaqondile i-porosity yolwelwesi olunogqinsi olufanayo kanye nokucaciswa kwempahla eluhlaza kodwa futhi ihlobene eduze nokuminyana kwezinto zokusetshenziswa zesihlukanisi kanye nokucaciswa kogqinsi lwaso. Uhlelo lolimi luthinta ngqo ukumelana kwangaphakathi, amandla esilinganiso, ukusebenza komjikelezo, nokuphepha kwamabhethri e-lithium.
Ugqinsi lwesihlukanisi lubaluleke kakhulu ekusebenzeni nasekuphepheni kukonke kwebhethri. Ukufana kokuqina kuyimethrikhi eqinile yokulawula ikhwalithi ngesikhathi sokukhiqiza, enokuchezuka okudingekayo ukuze kuhlale ngaphakathi kwamazinga omkhakha nokubekezelela ukuhlangana kwebhethri. Isihlukanisi esizacile sinciphisa ukumelana kwama-ion e-lithium axazululiwe ngesikhathi sokuthutha, sithuthukisa ukuqhutshwa kwe-ionic kanye nokunciphisa i-impedance. Kodwa-ke, ukuzaca okweqile kwenza ukugcinwa koketshezi kube buthaka kanye nokufakwa kwe-elekthronikhi, kube nomthelela omubi ekusebenzeni kwebhethri.
Ngenxa yalezi zizathu, ukujiya nokuhlola ukuminyana kwe-real kwesihlukanisi sekuphenduke izinyathelo ezibalulekile zokulawula ikhwalithi ekukhiqizeni ibhethri ye-lithium, okunquma ngokuqondile ukusebenza kwebhethri, ukuphepha, nokungaguquguquki. Ukuminyana kwendawo okuphakeme kakhulu kuvimbela ukuthutha kwe-lithium-ion, kunciphisa amandla wesilinganiso; ukuminyana kwendawo okuphansi kakhulu kubeka engcupheni amandla emishini, kubeke engcupheni ukuphuka kanye nezingozi zokuphepha. Izihlukanisi ezizacile ngokweqile ziyingozi ekungeneni kwe-electrode, okubangela amasekethe amafushane angaphakathi; izihlukanisi eziwugqinsi ngokweqile zandisa ukumelana kwangaphakathi, zehlisa ukuminyana kwamandla kanye nokusebenza kahle kokushaja kokushaja.
Ukuze kubhekwane nalezi zinselele, i-Dacheng Precision yethula igeji yokulinganisa ye-X-ray yendawo (ukuqina) yobungcweti!
#I-X-ray yendawo yokuminyana (ukujiya) ukukala ukulinganisa
Le divayisi ifanelekele ukuhlola izinto ezihlukahlukene, okuhlanganisa izinto zobumba kanye ne-PVDF, ezinokunemba kokuphinda kwesilinganiso kwenani langempela × 0.1% noma ±0.1g/m², futhi ithole isitifiketi sokukhululwa emisebeni ukuze isebenze ngokuphephile. Isofthiwe yayo ihlanganisa amamephu okushisa esikhathi sangempela, izibalo zokulinganisa okuzenzakalelayo, imibiko yekhwalithi yomqulu, ngokuchofoza kanye i-MSA (Ukuhlaziywa Kwesistimu Yokulinganisa), neminye imisebenzi ekhethekile, okunika amandla ukusekelwa kokulinganisa ukunemba okuphelele.
# I-interface yesoftware
#Imephu yokushisa yesikhathi sangempela
Uma sibheka phambili, i-Dacheng Precision izozibophezela ku-R&D, iqhubeke ithuthukela emingceleni ejulile yezobuchwepheshe futhi ihlanganise ubuhlakani obusha kuyo yonke imikhiqizo nensizakalo. Ngokusebenzisa ubuchwepheshe obusezingeni eliphezulu, sizohlola izixazululo zokulinganisa ezihlakaniphile nezinembe kakhudlwana, sakhela amakhasimende ethu amasistimu ezinsiza zobuchwepheshe asebenza kahle futhi athembekile. Ngobuciko bokwakha imikhiqizo ye-premium namandla okushayela izinto ezintsha, sizibophezele ekuqhubekiseleni phambili imboni yebhethri ye-lithium enkathini entsha yentuthuko yekhwalithi ephezulu!
