Ngenxa yophuhliso olukhawulezileyo lwebhetri ye-lithium ion kwizixhobo eziphathwayo nakwezinye iindawo, ukusebenza kwayo okuphantsi kobushushu akukwazi ukuziqhelanisa nemozulu ekhethekileyo yobushushu obuphantsi okanye imeko-bume egqithisileyo kuya kucaca ngakumbi nangakumbi. Phantsi kweemeko zobushushu obuphantsi, amandla okukhupha asebenzayo kunye namandla okukhupha asebenzayo ebhetri ye-lithium ion aya kuncipha kakhulu. Okwangoku, ayinakutshajwa phantsi kwe--10℃, nto leyo ethintela kakhulu ukusetyenziswa kwebhetri ye-lithium ion.
Ibhetri iyoyika kakhulu ubushushu obuphantsi, kwindawo enobushushu obuphantsi umthamo webhetri uphantsi kunomthamo wobushushu obuqhelekileyo, nangona ngoku ibhetri ingenakugcinwa, ingakumbi ebusika, ubomi bebhetri yezithuthi zombane kunye nezinye izixhobo ezikrelekrele ze-lithium buya kuncitshiswa ngokufanelekileyo, kwaye ubomi benkonzo yebhetri ye-lithium kwindawo enobushushu obuphantsi buya kufinyezwa kakhulu.
Impembelelo yobushushu obuphantsi kwiibhetri
1. Xa ubushushu buhla, izinga lokuphendula kwe-electrode nalo liyehla. Ukuba i-voltage yebhetri ihlala ihleli kwaye umsinga wokukhupha uyancipha, amandla okukhupha ebhetri nawo aya kuncipha.
2. Phakathi kwazo zonke izinto ezichaphazela imeko-bume, ubushushu bunempembelelo enkulu ekusebenzeni kwebhetri kunye nokukhupha itshaja. Impendulo ye-electrochemical kwi-electrode okanye kwi-electrolyte interface inxulumene nobushushu bemeko-bume, kwaye i-electrode okanye i-electrolyte interface ithathwa njengentliziyo yebhetri.
3. ubushushu bunyuka xa ibhetri ye-lithium polymer iphuma ngamandla;
4. ubushushu bukwachaphazela isantya sokudlulisa i-electrolyte, ubushushu buyanyuka, ubushushu bokudlulisa buyehla, udluliselo luyehla, ukusebenza kokutshaja nokukhupha ibhetri nako kuyachaphazeleka. Kodwa ubushushu obuphezulu kakhulu, obungaphezulu kwama-45 degrees Celsius, bunokuphazamisa ibhalansi yeekhemikhali kwibhetri kwaye bubangele iziphumo ebezingalindelekanga.
Kungenxa yokuba ibhetri inamandla kakhulu ngenxa yempembelelo yobushushu obuphantsi, abavelisi abaninzi abanamandla baphuhlisa iibhetri ezinobushushu obuphantsi. Kwangaxeshanye, amashishini adibanisa iibhetri ze-lithium aphuhlisa iiterminals zebhetri ezinganyangekiyo kubushushu obuphantsi.
Njengeshishini lezobuchwepheshe obuphezulu lephondo, uthotho lwe-Amass oluxhathisa ubushushu obuphantsi lwebhetri olusetyenziswa kakhulu kwizixhobo zokugcina amandla, izixhobo zegadi zokulima ikhephu, izithuthi zombane kunye nezinye izixhobo ezikrelekrele ezihambayo. Ubushushu obuphantsi buya kwenza iqokobhe leplastiki lesixhobo sebhetri libe buthathaka, kwaye okukhona ubushushu obuphantsi bokubhitya, kokukhona ukusebenza kakuhle kobushushu obuphantsi kwesixhobo seplastiki soqhagamshelo. Isixhumi sebhetri esixhathisa ubushushu obuphantsi se-Amass LC samkela iplastiki yobunjineli yePBT, engasetyenziswa kubushushu obuphantsi be--40℃. Kulo bushushu, sinokuqinisekisa ukuba iqokobhe leplastiki lesixhobo sebhetri aliyi kubhitya kwaye liqhekeke, kwaye siqinisekise ukusebenza kakuhle kokuthwala kombane kwesixhumi sebhetri.
Uthotho lwe-LC lusebenzisa umqhubi wekopolo, onokuthi usakhusele i-plasticity ephezulu kubushushu obuphantsi. Ukumelana kwebhendi kuncipha ngokuncipha kobushushu, nto leyo enokuqinisekisa ngempumelelo iingenelo ezibonakalayo zokuxhathisa okuphantsi kunye nokuthwala okukhulu kwamandla ebhetri.
Uthotho lwe-LC aluphuculi nje kuphela ukuhanjiswa kombane ngethusi, kodwa lukwaphucula nolwakhiwo loqhagamshelwano. Uqhagamshelwano lwangaphakathi lwentwasahlobo yesithsaba, unxibelelwano oluphindwe kathathu, oluchasene nokuqhekeka ngequbuliso ngexesha lokufakwa, luphucula kakhulu ubomi benkonzo yesixhumi sebhetri ye-lithium.
