Isingeniso:
Hawu, lokhu okusunguliwe kungase kuchithe ngokuphelele imithetho yomdlalo embonini yamandla entsha yomhlaba wonke! NgoFebhuwari 12, 2025, iphephabhuku lamazwe ngamazwe elihamba phambili i-Nature lashicilela impumelelo eguquguqukayo. Ithimba lika-Peng Huisheng/Gao Yue wase-Fudan University e-China lisungule entshaI-lithium battery "rejuvenation" ubuchwepheshe, ukwephula izimiso zokuklama zendabuko zamabhethri e-lithium iminyaka engaphezu kwengu-30, enganweba impilo yebhethri izikhathi ezingaphezu kwezingu-10! Ibhethri elijwayelekile le-lithium iron phosphate lisagcina u-96% womthamo walo ngemuva kwemijikelezo ye-11,818 yokushaja nokukhipha! Uyazi, amabhethri e-lithium okwamanje asemakethe asetshenziselwa izikhathi ezingu-1000-2000.
Kusho ukuthini lokhu? I-Tesla yayivame ukudinga ukushintsha ibhethri layo njalo eminyakeni engu-6-8, kodwa manje ingaqhutshwa iminyaka engu-60 ngaphandle kokuyishintsha! I-iPhone yakho ingashajwa futhi ishajwe izikhathi ezingu-10,000 ngaphandle kokulahlekelwa amandla!
Ugqozi lobuchwepheshe bokulungisa ibhethri luvela ekwelapheni kwabantu
Kwatholakala kanjani lokhu okuyisimangaliso okutholwe?
Njengokwelapha izifo zabantu, sigxila ekulungiseni izinkinga eziwumgogodla zamabhethri kuyilapho sivikela izingxenye zawo ezinempilo,” kuchaza uGao Yue, umcwaningi waseFudan University.
Ekuqaleni, isizathu esiyinhloko "sokuguga" kwamabhethri e-lithium kwakuwukulahlekelwa kwe-lithium ion. Njengoba nje ukuntuleka kwesakhi esithile emzimbeni womuntu kungaholela ekuguleni, amabhethri nawo angathola ukwehla ekusebenzeni ngenxa yokungondleki. Umbono ophumelelayo weqembu uthi: Singakwazi yini ukugcwalisa ama-ion e-lithium alahlekile ebhethrini njengokujova esigulini?
I-AI isiza ukunqamula kubuchwepheshe obubalulekile bokulinganisa ibhethri
Nokho, ukuthola "umjovo" ofanele akuwona umsebenzi olula. Le molekyuli yenethiwekhi kufanele ngesikhathi esisodwa ihlangabezane nezidingo eziqinile zezakhiwo zomzimba nezamakhemikhali:
- Ukuba nomsebenzi ofanele we-electrochemical kanye nobubanzi be-voltage yokubola.
- I-solubility efanelekile ku-electrolyte.
- Inokuqina komoya okuhle kakhulu kanye nokuzinza kwamakhemikhali.
- I-acidity efanelekile, i-alkalinity, ne-kinetics yokusabela.
- Imikhiqizo yokubola kufanele iphephe futhi ingabi yingozi.
- Okubaluleke kakhulu, kufanele kube ishibhile futhi kube lula ukukhuphula umkhiqizo.
I-Artificial intelligence ithola izinto ezibalulekile
Ngaphandle kokulandela isibonelo, ithimba labacwaningi laphendukela kubuhlakani bokwenziwa. Bafake kudijithali izici zamangqamuzana futhi basebenzise ukufunda ngomshini ukuze bathole izimpendulo enanini elikhulu le-organic chemistry, i-electrochemistry kanye nedatha yobunjiniyela bezinto zokwakha.
Ukusebenza kanzima kwaba nemiphumela emihle! Ngemva kweminyaka engu-4 yokusebenza kanzima, ekugcineni bathola ikhambi elikahle: CF3SO2Li (lithium trifluoromethanesulfonate). Le ngqamuzana ifana nesithuthi esincane, esithwala ama-electron e-lithium ekugcineni futhi iwakhiphe ngokuphephile njengegesi ngakolunye uhlangothi ngemva kokuqedwa kokuthutha.
Imiphumela yokuhlolwa iyashaqisa!
Esivivinyweni, ibhethri elithole lokhu "ukwelashwa okunembayo" lisenokusebenza eduze neleveli yefekthri ngisho nangemva kokushaja nokukhipha imijikelezo engu-12000 kuya ku-60000. Lokhu akugcini nje ngokunweba impilo yebhethri, kodwa futhi kunikeza isixazululo sezobuchwepheshe esingaba khona sokuxazulula inkinga yokungcoliswa kwebhethri okukhulu.
Okujabulisa kakhulu ukuthi lobu buchwepheshe buvule amathuba amasha ngokuphelele:
Kusetshenziswe isistimu yebhethri ye-lithium yamahhala ye-cathode ene-voltage engu-3.0V kanye nokuminyana kwamandla okungafika ku-1192 Wh/kg.
Kuthuthukiswe ibhethri lesikhwama se-organic sulfurized polyacrylonitrile cathode enamandla amakhulu angu-388 Wh/kg.
Umthelela Wenguquko
Lokhu kuphumelela kuzoshintsha ngokuphelele imithetho yomdlalo embonini entsha yamandla:
Kuzonciphisa kakhulu izindleko zokusebenzisa izimoto zikagesi, kunciphise kakhulu ukungcoliswa kwemvelo okubangelwa ukuchithwa kwebhethri, futhi kuvule imibono emisha yokuklama amabhethri amasha; into ejabulisa kakhulu ukuthi izindleko zalobu buchwepheshe zikhulu kakhulu - kulindeleke ukuthi ziphendule ngaphansi kwe-10% yezindleko zebhethri, okusho ukuthi inamandla okusebenzisa ukuhweba ngezinga elikhulu!
Njengoba umcwaningi uGao Yue asho: Kungakhathaliseki ukuthi kuwukwelula ukuphila kwebhethri noma ukuvimbela ukulahlwa okukhulu nokungcoliswa kwemvelo, lokhu "kwelashwa okunembayo" kunikeza isisombululo sobuchwepheshe esingenzeka. Lolu cwaningo alukhombisi nje kuphela amandla amasha eShayina emkhakheni wamandla amasha, kodwa futhi lumemezela ukufika kwenkathi entsha. Esikhathini esizayo esiseduze, "ukukhathazeka kwebhethri" kungase kube umlando. Masibheke phambili ekuhwebeni kwalobu buchwepheshe bezinguquko ngokushesha ngangokunokwenzeka!
