Chiyambi:
Wow, zomwe zapezedwazi zitha kugubuduza malamulo amasewera pamsika wamagetsi wapadziko lonse lapansi! Pa February 12, 2025, magazini yapamwamba yapadziko lonse ya Nature inafalitsa zosintha. Gulu la a Peng Huisheng/Gao Yue ochokera ku yunivesite ya Fudan ku China anatulukira zatsopanolithiamu batire "rejuvenation" luso, kuphwanya mfundo zachikhalidwe zamabatire a lithiamu kwazaka zopitilira 30, zomwe zitha kukulitsa moyo wa batri nthawi zopitilira 10! Battery wamba ya lithiamu iron phosphate imasungabe 96% ya mphamvu yake pambuyo pa 11,818 charge and discharge cycle! Mukudziwa, mabatire a lithiamu omwe ali pamsika amagwiritsidwa ntchito nthawi 1000-2000.
Kodi izi zikutanthauza chiyani? A Tesla ankafunika kusintha batire yake zaka 6-8 zilizonse, koma tsopano ikhoza kuyendetsedwa kwa zaka 60 popanda kuyisintha! IPhone yanu imatha kulipiritsidwa ndikutulutsidwa nthawi 10,000 osataya mphamvu!
Kudzoza kwaukadaulo wokonza mabatire kumachokera ku chithandizo chamunthu
Kodi chozizwitsa chimenechi chinapezeka bwanji?
Mofanana ndi kuchiza matenda a anthu, timayang’ana kwambiri kukonza zinthu zofunika kwambiri za mabatire pamene tikuteteza ziwalo zawo zathanzi,” analongosola motero Gao Yue, wofufuza pa yunivesite ya Fudan.
Poyambirira, chifukwa chachikulu cha "kukalamba" kwa mabatire a lithiamu kunali kutayika kwa ayoni a lithiamu. Monga momwe kusowa kwa michere ina m'thupi la munthu kungayambitse matenda, mabatire amathanso kuchepa chifukwa cha kuperewera kwa zakudya m'thupi. Lingaliro lopambana la gululi ndi: Kodi titha kubwezeretsanso ma ayoni a lithiamu mu batire monga kubaya jekeseni wodwala?
AI imathandizira kudutsa maukadaulo ofunikira a batri
Komabe, kupeza "jekeseni" yoyenera si ntchito yophweka. Molekyu yonyamulirayi iyenera nthawi imodzi kukwaniritsa zofunikira zakuthupi ndi zamankhwala:
- Kukhala ndi ntchito yoyenera ya electrochemical ndi mtundu wamagetsi owonongeka.
- Kusungunuka koyenera mu electrolyte.
- Ali ndi kukhazikika kwa mpweya wabwino komanso kukhazikika kwamankhwala.
- Acidity yoyenera, alkalinity, ndi reaction kinetics.
- Zinthu zowola ziyenera kukhala zotetezeka komanso zopanda vuto.
- Chofunika kwambiri, ziyenera kukhala zotsika mtengo komanso zosavuta kukulitsa kupanga.
Artificial intelligence imapeza zinthu zofunika kwambiri
Popanda chitsanzo chotsatira, gulu lofufuza linatembenukira ku luntha lochita kupanga. Adasintha mawonekedwe a mamolekyu ndikugwiritsa ntchito kuphunzira pamakina kuti apeze mayankho kuchokera kuzinthu zambiri zama organic chemistry, electrochemistry ndi data engineering engineering.
Kugwira ntchito mwakhama kunapindula! Pambuyo pa zaka 4 zogwira ntchito mwakhama, potsirizira pake anapeza njira yabwino yothetsera vutoli: CF3SO2Li (lithium trifluoromethanesulfonate). Molekyuyi ili ngati chonyamulira chaching'ono, chonyamula ma elekitironi a lithiamu kumapeto kwina ndikuwatulutsa mosatekeseka ngati mpweya kumapeto kwina mayendedwe akamaliza.
Zotsatira zoyeserera ndizodabwitsa!
Poyesera, batire yomwe idalandira "mankhwala olondola" akadali ndi magwiridwe antchito pafupi ndi mulingo wa fakitale ngakhale pambuyo pa 12000 mpaka 60000 kuzungulira ndikutulutsa. Izi sizimangowonjezera moyo wa batri, komanso zimapereka njira yotheka yaukadaulo yothetsera vuto la kuipitsidwa kwakukulu kwa batire.
Chosangalatsa kwambiri ndichakuti ukadaulo uwu watsegula mwayi watsopano:
Anakhazikitsa batire ya lithiamu yaulere ya cathode yokhala ndi voteji ya 3.0V ndi kachulukidwe kamphamvu mpaka 1192 Wh/kg.
Anapanga batri ya organic sulfurized polyacrylonitrile cathode pouch yokhala ndi mphamvu zofikira 388 Wh/kg.
Revolution Impact
Kupambana uku kusinthiratu malamulo amasewera mumakampani atsopano amagetsi:
Zidzachepetsa kwambiri mtengo wogwiritsira ntchito magalimoto amagetsi, kuchepetsa kwambiri kuwonongeka kwa chilengedwe chifukwa cha kuchotsedwa kwa batri, ndikutsegula malingaliro atsopano pakupanga mabatire atsopano; chosangalatsa kwambiri ndi chakuti mtengo wa teknolojiyi ndi wochuluka kwambiri - uyenera kuwerengera ndalama zosachepera 10% za mtengo wa batri, zomwe zikutanthauza kuti zimakhala ndi mwayi wogwiritsa ntchito malonda akuluakulu!
Monga wofufuza Gao Yue adati: Kaya ndikukulitsa moyo wa batri kapena kupewa kusiyidwa kwakukulu ndi kuipitsidwa kwa chilengedwe, "mankhwala olondola" awa amapereka yankho lotheka laukadaulo. Kafukufukuyu samangowonetsa mphamvu zatsopano za China pazamphamvu zatsopano, komanso zimawonetsa kubwera kwa nyengo yatsopano. Posachedwapa, "nkhawa ya batri" ikhoza kukhala mbiri. Tiyeni tiyembekeze mwachidwi kutsatsa kwaukadaulo wosinthawu posachedwa!
