Kwihlabathi le-microscopic yeebhetri ze-lithium, kukho "umlindi ongabonakaliyo" obalulekileyo - umahluli, owaziwa ngokuba yi-membrane yebhetri. Isebenza njengenxalenye ephambili yeebhetri ze-lithium kunye nezinye izixhobo ze-electrochemical. Ikakhulu yenziwe nge-polyolefin (i-polyethylene PE, i-polypropylene PP), ezinye izahluli ezikumgangatho ophezulu nazo zamkela iingubo ze-ceramic (umzekelo, i-alumina) okanye izinto ezidibeneyo zokuphucula ukuxhathisa ubushushu, zizenza iimveliso zefilimu ezivulekileyo. Ubukho bayo busebenza njenge-"firewall" eyomeleleyo, ihlukanisa ngokwasemzimbeni i-electrode elungileyo kunye nengalunganga yebhetri ye-lithium ukukhusela imijikelezo emifutshane, ngelixa kwangaxeshanye isebenza "njengomgwaqo omkhulu we-ion," ovumela i-ion ukuba ihambe ngokukhululekileyo kwaye iqinisekise ukusebenza kwebhetri eqhelekileyo.
Igrama kunye nobukhulu besahluli, iiparamitha ezibonakala ziqhelekileyo, zifihla "iimfihlo" ezinzulu. Igrama (i-areal density) yezixhobo ze-lithium zokwahlula ibhetri ayibonisi nje ngokungathanga ngqo i-porosity ye-membrane ezinobunzima obufanayo kunye neenkcukacha zemathiriyeli ekrwada kodwa inxulumene ngokusondeleyo nobuninzi bezinto eziluhlaza zomahluli kunye neenkcukacha zobukhulu bayo. Igrammage ichaphazela ngokuthe ngqo ukuchasana kwangaphakathi, amandla okulinganisa, ukusebenza komjikelo, kunye nokhuseleko lweebhetri ze-lithium.
Ubukhulu besahluli bubaluleke ngakumbi ekusebenzeni jikelele kwebhetri kunye nokhuseleko. Ukutyeba ngokufanayo yimetric engqongqo yolawulo lomgangatho ngexesha lemveliso, kunye nonxano olufunekayo ukuze uhlale ngaphakathi kwemigangatho yoshishino kunye nokunyamezela ukudityaniswa kweebhetri. Isahluli esincinci sinciphisa ukuchasana kwe-lithium ion esonjululweyo ngexesha lokuhamba, ukuphucula i-ionic conductivity kunye nokunciphisa i-impedance. Nangona kunjalo, ukubhitya okugqithisileyo kwenza buthathaka ugcino lolwelo kunye nokugqunywa kwe-elektroniki, kuchaphazela kakubi ukusebenza kwebhetri.
Ngezi zizathu, ukuxinana kunye novavanyo loxinaniso lwendawo lwesahluli luye lwaba ngamanyathelo abalulekileyo okulawula umgangatho kwi-lithium yokuvelisa ibhetri, ukugqiba ngokuthe ngqo ukusebenza kwebhetri, ukhuseleko kunye nokungaguquguquki. Ukuxinana kwendawo ephakamileyo ngokugqithisileyo kuthintela ukuthuthwa kwe-lithium-ion, ukunciphisa izinga lokukwazi; uxinano oluphantsi kakhulu lwendawo lubeka esichengeni amandla omatshini, okubeka emngciphekweni wokuqhekeka kunye neengozi zokhuseleko. Izahluli ezibhityileyo ngokugqithisileyo umngcipheko wokungena kwe-electrode, ebangela iisekethe ezimfutshane zangaphakathi; izahluli ezityebileyo ezigqithisileyo zonyusa ukuchasana kwangaphakathi, zehlisa ukuxinana kwamandla kunye nokusebenza kakuhle kokukhutshwa kwentlawulo.
Ukujongana nale mingeni, i-Dacheng Precision yazisa ubuchwephesha bayo be-X-reyi yendawo yokulinganisa (ukutyeba) igeyiji yokulinganisa!
#X-reyi yendawo yoxinaniso (ukutyeba) umlinganiselo wokulinganisa
Esi sixhobo sikulungele ukuvavanya imathiriyeli eyohlukeneyo, kuquka iiseramikhi kunye nePVDF, ngomlinganiselo wokuchaneka okuphinda-phindayo kwexabiso lokwenyani × 0.1% okanye ±0.1g/m², kwaye sifumene isatifikethi sokukhululwa kwimitha yokusebenza ngokukhuselekileyo. I-software yayo ineemephu zexesha langempela, izibalo zokulinganisa ngokuzenzekelayo, iingxelo zomgangatho we-roll, i-MSA enye i-MSA (Uhlalutyo lweNkqubo yokulinganisa), kunye neminye imisebenzi ekhethekileyo, eyenza inkxaso yokulinganisa ngokuchanekileyo.
