Njengoba ibhethri le-lithium ion lithuthuka ngokushesha kumadivayisi eselula nakwamanye amasimu, ukusebenza kwalo okuphansi kokushisa akukwazi ukuzivumelanisa nesimo sezulu esikhethekile sokushisa okuphansi noma indawo ezungezile ebucayi kuya ngokuya kusobala. Ngaphansi kwezimo zokushisa okuphansi, amandla okukhipha asebenzayo kanye namandla okukhipha asebenzayo ebhethri le-lithium ion kuzoncipha kakhulu. Okwamanje, akunakwenzeka ukuthi lingashajwa kabusha ngaphansi kuka--10℃, okuvimbela kakhulu ukusetshenziswa kwebhethri le-lithium ion.
Ibhethri liyesaba kakhulu izinga lokushisa eliphansi, endaweni ephansi izinga lokushisa umthamo webhethri uphansi kunomthamo ojwayelekile wokushisa, yize manje ibhethri lingasalungiswa, ikakhulukazi ebusika, impilo yebhethri yezimoto zikagesi neminye imishini ehlakaniphile ye-lithium izoncishiswa ngokufanele, futhi impilo yesevisi yebhethri le-lithium endaweni ephansi izinga lokushisa izofinyezwa kakhulu.
Umphumela wokushisa okuphansi kumabhethri
1. Uma izinga lokushisa lehla, izinga lokusabela kwe-electrode nalo liyehla. Uma sicabanga ukuthi i-voltage yebhethri ihlala ingaguquki futhi ugesi wokukhipha uyancipha, amandla okukhipha ibhethri nawo azokwehla.
2. Phakathi kwazo zonke izici zemvelo, izinga lokushisa linethonya elikhulu ekusebenzeni kwebhethri kokushaja nokukhipha ibhethri. Ukusabela kwe-electrochemical esibonakalayo se-electrode noma se-electrolyte kuhlobene nokushisa kwemvelo, kanti isibonisi se-electrode noma se-electrolyte sibhekwa njengenhliziyo yebhethri.
3. izinga lokushisa liyakhuphuka uma amandla okukhipha ibhethri le-lithium polymer azokhuphuka;
4. izinga lokushisa liphinde lithinte ijubane lokudlulisa le-electrolyte, izinga lokushisa liyakhuphuka, izinga lokushisa lokudlulisa liyehla, i-transmission iyehla, ukusebenza kokushaja nokukhipha ibhethri nakho kuzothinteka. Kodwa izinga lokushisa eliphakeme kakhulu, elingaphezu kwama-degree Celsius angu-45, lingaphazamisa ibhalansi yamakhemikhali ebhethri futhi libangele imiphumela emibi.
Futhi kungenxa yokuthi izinga lokushisa eliphansi ebhethri likhulu kakhulu, abakhiqizi abaningi bamabhethri anamandla bathuthukisa amabhethri okushisa aphansi. Ngesikhathi esifanayo namabhizinisi okuxhumanisa amabhethri e-lithium aphansi nawo athuthukisa amatheminali ebhethri amelana nokushisa okuphansi.
Njengebhizinisi lesifundazwe elisezingeni eliphezulu, uchungechunge lwe-Amass olumelana nokushisa okuphansi lwebhethri lusetshenziswa kabanzi emishinini yokugcina amandla, ekutshaleni iqhwa ngamathuluzi engadini, ezimotweni zikagesi nakwezinye izinto ezihlakaniphile ezihambayo. Ukushisa okuphansi kuzokwenza igobolondo lepulasitiki lesixhumi sebhethri liqhekeke, futhi uma izinga lokushisa lokuqhekeka liphansi, kungcono ukusebenza kahle kokumelana nokushisa okuphansi kwegobolondo lepulasitiki. Isixhumi sebhethri esimelana nokushisa okuphansi se-Amass LC sisebenzisa ipulasitiki yobunjiniyela i-PBT, engasetshenziswa ekushiseni okuphansi okungu--40℃. Kuleli zinga lokushisa, lingaqinisekisa ukuthi igobolondo lepulasitiki lesixhumi sebhethri ngeke liqhekeke futhi liqhekeke, futhi liqinisekise ukusebenza okuhle kokuthwala amandla kwesixhumi sebhethri.
Uchungechunge lwe-LC lusebenzisa umqhubi wethusi, osengavikela i-plasticity ephezulu ekushiseni okuphansi. Ukumelana kwebhendi kwehla ngokuncipha kwezinga lokushisa, okungaqinisekisa ngempumelelo izinzuzo eziphawulekayo zokumelana okuphansi kanye nokuthwala kwamanje okukhulu kwezixhumi zebhethri.
Uchungechunge lwe-LC alugcini nje ngokuthuthukisa ukuqhutshwa kukagesi ngethusi, kodwa futhi luthuthukisa nesakhiwo sokuxhumana. Ukuxhumana kwangaphakathi kwentwasahlobo yomqhele, ukuxhumana okuphindwe kathathu, ukulwa nokuzamazama komhlaba kanye nokuqhekeka okungazelelwe ngesikhathi sokufakwa, kuthuthukisa kakhulu impilo yesevisi yesixhumi sebhethri le-lithium.
