Kwihlabathi leebhetri ze-lithium ezincinci, kukho "umlindi ongabonakaliyo" obalulekileyo - umhluzi, okwaziwa ngokuba yi-membrane yebhetri. Isebenza njengenxalenye ephambili yeebhetri ze-lithium kunye nezinye izixhobo ze-electrochemical. Ngokuyintloko zenziwe nge-polyolefin (i-polyethylene PE, i-polypropylene PP), ezinye izahluli eziphezulu nazo zisebenzisa iingubo ze-ceramic (umz., i-alumina) okanye izinto ezidityanisiweyo ukuphucula ukumelana nobushushu, zizenze zibe ziimveliso zefilimu eziqhelekileyo ezinemibhobho. Ubukho bayo busebenza njenge "firewall" eqinileyo, ehlukanisa ngokwasemzimbeni ii-electrode ezilungileyo nezingalunganga zebhetri ye-lithium ukuthintela iisekethe ezimfutshane, ngelixa ngaxeshanye isebenza njenge "ion highway" egudileyo, evumela ii-ion ukuba zihambe ngokukhululekileyo kwaye ziqinisekise ukusebenza kwebhetri eqhelekileyo.
Igrama kunye nobukhulu bomhluzi, iiparameter ezibonakala ziqhelekile, zifihla “iimfihlo” ezinzulu. Igrama (ubuninzi bezinto) zezinto zokwahlula ibhetri ye-lithium azibonisi nje ngokungangqalanga ubume bee-membrane ezinobukhulu obufanayo kunye neenkcukacha zezinto eziluhlaza kodwa zikwanxulumene ngokusondeleyo nobunzima bezinto eziluhlaza zomhluzi kunye neenkcukacha zobukhulu bazo. Igrama ichaphazela ngokuthe ngqo ukumelana kwangaphakathi, amandla okubaleka, ukusebenza komjikelo, kunye nokhuseleko lweebhetri ze-lithium.
Ubukhulu besihlukanisi bubaluleke ngakumbi ekusebenzeni nasekukhuselekeni kwebhetri iyonke. Ukufana kobukhulu yimilinganiselo engqongqo yolawulo lomgangatho ngexesha lemveliso, kunye nokuphambuka okufunekayo ukuze kuhlale ngaphakathi kwemigangatho yoshishino kunye nokunyamezelana kokuhlanganiswa kwebhetri. Isihlukanisi esincinci sinciphisa ukumelana nee-ion ze-lithium ezinyibilikisiweyo ngexesha lokuhamba, siphucula ukuhanjiswa kwe-ionic kunye nokunciphisa impedance. Nangona kunjalo, ukubhitya okugqithisileyo kunciphisa ukugcinwa kolwelo kunye nokufakelwa kwe-elektroniki, okuchaphazela kakubi ukusebenza kwebhetri.
Ngenxa yezi zizathu, ukuvavanya ubukhulu kunye noxinano lwe-areal ye-separator kube ngamanyathelo abalulekileyo okulawula umgangatho ekwenzeni ibhetri ye-lithium, okumisela ngokuthe ngqo ukusebenza kwebhetri, ukhuseleko, kunye nokuhambelana. Uxinano lwe-areal oluphezulu kakhulu luthintela ukuthuthwa kwe-lithium-ion, kunciphisa amandla esantya; uxinano lwe-areal oluphantsi kakhulu lubeka emngciphekweni amandla oomatshini, lubeka emngciphekweni ukuqhekeka kunye neengozi zokhuseleko. Abahluli abancinci kakhulu babeka emngciphekweni ukungena kwe-electrode, okubangela iisekethe ezimfutshane zangaphakathi; abahluli abanzima kakhulu bandisa ukumelana kwangaphakathi, banciphisa uxinano lwamandla kunye nokusebenza kakuhle kokukhupha itshaja.
Ukujongana nale mingeni, iDacheng Precision yazisa i-X-ray areal density (ukutyeba) yayo yobungcali yokulinganisa!
#I-X-ray areal density (ukutyeba) guage yokulinganisa
Esi sixhobo sifanelekile ukuvavanya izixhobo ezahlukeneyo, kuquka i-ceramics kunye ne-PVDF, kunye nokuchaneka kokulinganisa okuphindaphindwayo kwexabiso lokwenyani × 0.1% okanye ±0.1g/m², kwaye sifumene isatifikethi sokungahlawulisi imitha yokusebenza ngokukhuselekileyo. Isoftware yaso ineemephu zobushushu zexesha langempela, ukubalwa kokulinganisa ngokuzenzekelayo, iingxelo zomgangatho wokuqengqeleka, i-MSA (Uhlalutyo lweNkqubo yokulinganisa) kunye neminye imisebenzi ekhethekileyo, evumela inkxaso epheleleyo yokulinganisa ngokuchanekileyo.
