Ngokuthuthuka okusheshayo kwebhethri ye-lithium ion kumadivayisi eselula nakweminye imikhakha, ukusebenza kwayo okuphansi kwezinga lokushisa akukwazi ukuzivumelanisa nesimo sezulu esikhethekile sokushisa okuphansi noma imvelo eyedlulele iba sobala ngokwengeziwe. Ngaphansi kwezimo zokushisa eziphansi, amandla okukhipha asebenzayo namandla okukhipha asebenzayo ebhethri ye-lithium ion azokwehla kakhulu. Okwamanje, angeke ikwazi ukushajwa kabusha ngaphansi kuka -10 ℃, okuvimbela kakhulu ukusetshenziswa kwebhethri ye-lithium ion.
Ibhethri yesaba kakhulu izinga lokushisa eliphansi, endaweni yokushisa ephansi amandla ebhethri aphansi kunomthamo ojwayelekile wokushisa, nakuba manje ibhethri ayinayo isondlo, ikakhulukazi ebusika, impilo yebhethri yezimoto zikagesi nezinye izinto ezihlakaniphile ze-lithium zizoba. kuncishiswe ngokufanele, futhi impilo yesevisi yebhethri ye-lithium endaweni yokushisa ephansi izofinyezwa kakhulu.
Umthelela wezinga lokushisa eliphansi kumabhethri
1. Lapho izinga lokushisa lehla, izinga lokuphendula le-electrode nalo liyehla. Uma sicabanga ukuthi i-voltage yebhethri ihlala ingashintshi futhi amandla okukhipha ayancipha, ukuphuma kwamandla ebhethri nakho kuzokwehla.
2. Phakathi kwazo zonke izici zemvelo, izinga lokushisa linethonya elikhulu ekusebenzeni kokushajwa kwebhethri. Ukusabela kwe-electrochemical kusixhumi esibonakalayo se-electrode noma i-electrolyte kuhlobene nezinga lokushisa lemvelo, futhi isixhumi esibonakalayo se-electrode noma i-electrolyte kuthathwa njengenhliziyo yebhethri.
3. izinga lokushisa liyakhuphuka lithium polymer amandla okukhipha ibhethri azovuka;
4. izinga lokushisa liphinde lithinte ijubane lokudlulisela le-electrolyte, izinga lokushisa liyakhuphuka, izinga lokushisa lokudlulisela liyehla, ukudluliswa kwehla ijubane, ukushajwa kwebhethri nokusebenza kokushajwa nakho kuzothinteka. Kodwa izinga lokushisa eliphakeme kakhulu, elingaphezu kuka-45 degrees Celsius, lingaphazamisa ibhalansi yamakhemikhali ebhethrini futhi libangele imiphumela engemihle.
Futhi kungenxa yokuthi umthelela wezinga lokushisa eliphansi ebhethri lilikhulu kakhulu, ngakho-ke abakhiqizi abaningi bebhethri abanamandla bakha amabhethri okushisa aphansi. Ngesikhathi esifanayo njengoba amabhizinisi e-lithium battery downstream athuthukisa amatheminali ebhethri amelana nezinga lokushisa eliphansi
Njengebhizinisi lesifundazwe lobuchwepheshe obuphezulu, uchungechunge lwe-Amass lwesixhumi sebhethri esikwazi ukumelana nokushisa okuphansi kwe-LC sisetshenziswa kakhulu ezintweni zokugcina amandla, amathuluzi asengadini ekuqhutshweni kweqhwa, izimoto zikagesi nezinye izinto zokusebenza ezihlakaniphile ezihambayo. Izinga lokushisa eliphansi lizokwenza igobolondo lepulasitiki lesixhumi sebhethri libe brittle, futhi ukwehla kwezinga lokushisa le-embrittleness, kungcono ukusebenza okumelana nokushisa okuphansi kwegobolondo lepulasitiki. Uchungechunge lwe-Amass LC isixhumi sebhethri esimelana nokushisa okuphansi samukela i-PBT yepulasitiki yobunjiniyela, engasetshenziswa ekushiseni okuphansi okungu -40℃. Kuleli zinga lokushisa, lingaqinisekisa ukuthi igobolondo lepulasitiki lesixhumi sebhethri ngeke libe yi-embrittlement kanye nokuphuka, futhi liqinisekise ukusebenza okuhle kokuthwala kwamanje kwesixhumi sebhethri.
Uchungechunge lwe-LC lwamukela umqhubi wethusi, osengakwazi ukuvikela ipulasitiki ephezulu ekushiseni okuphansi. I-resistivity yebhendi iyancipha ngokuncipha kwezinga lokushisa, okungaqinisekisa ngempumelelo izinzuzo zesici zokumelana okuphansi nokuthwala kwamanje okukhulu kwezixhumi zebhethri.
Uchungechunge lwe-LC alugcini nje ukuthuthukisa ukuqhutshwa kukagesi ngethusi, kodwa futhi luthuthukisa isakhiwo sokuxhumana. Ukuxhumana kwangaphakathi kwentwasahlobo yomqhele, ukuthintana okuphindwe kathathu, i-anti-seismic kanye nokunqamuka okungazelelwe ngesikhathi sokufakwa, kuthuthukisa kakhulu impilo yesevisi yesixhumi sebhethri ye-lithium.
