Isingeniso:
Wow, lokhu kwasungulwa kungangigumbuqela ngokuphelele imithetho yomdlalo embonini yamandla eNtsha Yezwe Lomhlaba! NgoFebhuwari 12, 2025, i-International Top Journal Imvelo yashicilela impumelelo yezinguquko. Iqembu lePeng Huiseseng / Gao Yue elivela eFudan University eChina lasungula okushaubuchwepheshe bebhethri le-lithium "resunenation", ukwephula imigomo yokuqamba yendabuko yamabhethri e-lithium iminyaka engaphezu kwengu-30, enganweba impilo yebhethri ngezikhathi ezingaphezu kwezingu-10! Ibhethri le-Lithium Iron Phosphate elijwayelekile ligcina ama-96% omthamo walo ngemuva kokushaja okungu-11,818 kanye nemijikelezo yokukhipha! Uyazi, amabhethri e-lithium njengamanje emakethe asetshenziselwa izikhathi eziyi-1000-2000.
Kusho ukuthini lokhu? I-Tesla esetshenziselwa ukudinga ukumiselela ibhethri yayo njalo eminyakeni engama-6-8, kepha manje ingaqhutshwa iminyaka engama-60 ngaphandle kokuyifaka esikhundleni! I-iPhone yakho ingakhokhiswa futhi ikhishwe izikhathi eziyi-10,000 ngaphandle kokulahlekelwa amandla!
Ukugqugquzela ubuchwepheshe bokulungisa ibhethri kuvela ekwelashweni komuntu
Lokhu kutholwa okuyisimangaliso kwenzeka kanjani?
Njengokwelapha izifo zabantu, sigxile ekuxazululeni izingqinamba ezibalulekile zamabhethri ngenkathi zivikela izingxenye zazo ezinempilo, "kuchaza uGao Yue, umcwaningi eFudan University.
Ekuqaleni, isizathu esiyinhloko sokwenza "ukuguga" kwamabhethri e-lithium kwakuwukulahlekelwa yi-lithium ion. Njengoba nje ukungasho lutho kwezakhi ezithile emzimbeni womuntu kungaholela ekuguleni, amabhethri nawo angathola ukwehla kokusebenza ngenxa yokungondleki. Umqondo wobuciko weqembu yilena: Singabuyisela kabusha ama-lithium ion alahlekile ebhethri afana nokunikeza umjovo isiguli?
I-AI isiza ukwephula ubuchwepheshe bokulinganisa kwebhethri
Kodwa-ke, ukuthola "umjovo" ofanelekayo akuwona umsebenzi olula. Le molecule yenethiwekhi kufanele ihlangabezane ngasikhathi sinye ihlangabezana nezidingo zempahla eqinile eqinile eqinile:
- Ukuba nomsebenzi ofanele we-electrochemical kanye nobubanzi be-voltage.
- I-solubity efanelekile ku-electrolyte.
- Inokuqina komoya okuhle nokuqina kwamakhemikhali.
- I-acidity efanelekile, i-alkalinity, kanye ne-kinetics yokuphendula.
- Imikhiqizo yokubola kumele iphephe futhi ibe nengozi.
- Okubaluleke kakhulu, kufanele kube okushibhile futhi kube lula ukukhiqizwa.
Ubuhlakani bokufakelwa buthola izinto ezibalulekile
Ngaphandle kokungalandelwa okulandelayo, iqembu lokucwaninga laphenduka ubuhlakani bokufakelwa. Bakhulisa izakhiwo ze-molecular kanye nokufunda komshini osetshenzisiwe ukuthola izimpendulo ezivela kwinani elikhulu le-organic chemistry, i-electrochechemistry kanye nedatha yonjiniyela.
Umsebenzi onzima ukhokhelwe! Ngemuva kweminyaka engu-4 yokusebenza kanzima, ekugcineni bathola isixazululo esifanelekile: CF3SO2LI (I-Lithium TrifluoromethanesFulfonate). Le molecule ifana ne-transporter encane, iphethe ama-elektroni e-lithium ngakolunye uhlangothi futhi ibabambise ngokuphepha njengegesi ngakolunye uhlangothi ngemuva kokuqedwa kwezokuthutha.
Imiphumela yokuhlola iyashaqisa!
Esivivinyweni, ibhethri elathola lokhu "ukwelashwa okunembile" kusaseduze kweleveli yefektri ngisho nangemva kokushaja okungu-12000 kuya ku-60000. Lokhu akupheli nje kuphela empilweni yebhethri, kepha futhi kuhlinzeka ngesisombululo sezobuchwepheshe esinokwenzeka sokuxazulula inkinga yokungcoliswa kwebhethri enkulu.
Okujabulisa ngokwengeziwe ukuthi lobu buchwepheshe buvule amathuba amasha ngokuphelele:
Iqa umthetho we-Lithium Free Conthode Battery System nge-3.0V kanye nobuningi bamandla abafinyelela ku-1192 wh / kg.
Uthuthukise i-polyfurized sulkurized polyacrylonitrile cathode cathode yebhethri nge-density yamandla engu-388 wh / kg.
Umthelela wokuguqula
Lokhu kuphumelela kuzoshintsha ngokuphelele imithetho yomdlalo embonini yamandla amasha:
Kuzonciphisa kakhulu izindleko zokusebenzisa izimoto zikagesi, zinciphisa kakhulu ukungcoliswa kwemvelo okubangelwa ukusakazeka kwebhethri, futhi uvule imibono emisha yokwakhiwa kwamabhethri amasha; Into ejabulisa kakhulu ukuthi izindleko zalobu buchwepheshe zibaluleke kakhulu - kulindeleke ukuthi zilandise ngaphansi kwe-10% yezindleko zebhethri eziphelele, okusho ukuthi inamandla okusetshenziswa kwezinga elijwayelekile!
Njengoba umcwaningi uGao Yue uthe: Noma ngabe ukwelula impilo yebhethri noma ukuvimba ukulahla okuphezulu nokungcola okukhulu kanye nokungcoliswa kwemvelo, lokhu "ukwelashwa okunembile" kunikeza ikhambi lobuchwepheshe elinokwenzeka. Lolu cwaningo alubonisi amandla amasha e-China kuphela emkhakheni wamandla amasha, kodwa futhi uvimba ukufika kwenkathi entsha. Maduze nje, "ukukhathazeka kwebhethri" kungaba ngumlando. Ake sibheke phambili ekuthengisweni kwalobu buchwepheshe bezinguquko ngokushesha okukhulu!
