Wow, chigadzirwa ichi chinogona kukanganisa zvachose mitemo yemutambo muindasitiri yesimba idzva pasi rose! Musi wa12 Kukadzi 2025, magazini yepamusoro yepasi rose yeNature yakaburitsa shanduko huru. Chikwata chaPeng Huisheng/Gao Yue vekuFudan University kuChina chakagadzira chigadzirwa chitsvatekinoroji ye "kuvandudza" bhatiri re lithium, kutyora misimboti yekugadzirwa kwemabhatiri e lithium kwemakore anopfuura makumi matatu, izvo zvinogona kuwedzera hupenyu hwebhatiri nekanopfuura kagumi! Bhatiri re lithium iron phosphate rinoramba richichengetedza 96% yesimba raro mushure mekuchaja nekuburitsa magetsi ka11,818! Unoziva, mabhatiri e lithium ari pamusika parizvino anoshandiswa ka1000-2000.
Izvi zvinorevei? Tesla yaimboda kutsiva bhatiri rayo makore ese matanhatu kusvika masere, asi ikozvino inogona kufambiswa kwemakore makumi matanhatu isina kutsiva! iPhone yako inogona kuchajwa uye kuburitswa kagumi pasina kurasikirwa nemagetsi!
Kurudziro ye tekinoroji yekugadzirisa mabhatiri inobva mukurapa kwevanhu
Kuwanikwa uku kunoshamisa kwakatanga sei?
"Sekurapa zvirwere zvevanhu, tinonyanya kutarisa pakugadzirisa matambudziko makuru emabhatiri uku tichichengetedza nhengo dzawo dzine hutano," akadaro Gao Yue, muongorori wepaFudan University.
Pakutanga, chikonzero chikuru chekukwegura kwemabhatiri e-lithium kwaive kurasikirwa nemaion e-lithium. Sezvo kushaikwa kwechimwe chikafu mumuviri wemunhu kuchigona kukonzera kurwara, mabhatiri anogonawo kuona kudzikira kwekushanda nekuda kwekushaya chikafu chakakwana. Pfungwa huru yechikwata ndeyekuti: Tinogona here kuzadza maion e-lithium akarasika mubhatiri sekupa jekiseni kumurwere?
AI inobatsira kuburitsa matekinoroji akakosha ekuenzanisa mabhatiri
Zvisinei, kuwana "jekiseni" rakakodzera hakusi nyore. Molekyuri iyi inofanira kusangana panguva imwe chete nezvinodiwa zvemuviri uye zvemakemikari:
- Kuva nemagetsi akakodzera uye huwandu hwemagetsi ekuora.
- Kunyungudika kwakakodzera mu electrolyte.
- Ine kugadzikana kwemhepo kwakanaka uye kugadzikana kwemakemikari.
- Acid yakakodzera, alkalinity, uye reaction kinetics.
- Zvinhu zvinoora zvinofanira kunge zvakachengeteka uye zvisina njodzi.
- Chinonyanya kukosha ndechekuti inofanira kunge yakachipa uye iri nyore kuwedzera kugadzirwa kwayo.
Uchenjeri hwekugadzira hunowana zvinhu zvakakosha
Pasina muenzaniso wekutevera, chikwata chevaongorori chakatendeukira kuhungwaru hwekugadzira. Vakashandura hunhu hwemamorekuru mudhijitari uye vakashandisa kudzidza kwemuchina kuti vawane mhinduro kubva muhuwandu hwakawanda hwe data re organic chemistry, electrochemistry uye materials engineering.
Basa rakaoma rakabudirira! Mushure memakore mana ekushanda nesimba, vakazowana mhinduro yakanaka: CF3SO2Li (lithium trifluoromethanesulfonate). Molekyu iyi yakaita semuchina mudiki wekutakura, unotakura maerekitironi e lithium kune rimwe divi woaburitsa zvakachengeteka segasi kune rimwe divi mushure mekunge kutakurwa kwapera.
Mhedzisiro yekuedza iyi inoshamisa!
Mukuyedza uku, bhatiri rakawana "kurapwa kwakarurama" rakaramba richishanda zvakanaka kusvika padanho remufekitori kunyangwe mushure mekuchaja nekuburitsa zvinhu kubva pa12000 kusvika 60000. Izvi hazvingogumiri pakuwedzera hupenyu hwebhatiri, asiwo zvinopa mhinduro yehunyanzvi yekugadzirisa dambudziko rekusvibiswa kwemarara emabhatiri.
Chinonyanya kufadza ndechekuti tekinoroji iyi yakavhura mikana mitsva zvachose:
Ndakaisa sisitimu yebhatiri isina lithium cathode ine voltage ye3.0V uye density yesimba inosvika 1192 Wh/kg.
Yakagadzira bhatiri re polyacrylonitrile cathode pouch rine simba re388 Wh/kg.
Mhedzisiro Yechimurenga
Kubudirira uku kuchachinja zvachose mitemo yemutambo muindasitiri itsva yesimba:
Zvichaderedza zvakanyanya mutengo wekushandisa mota dzemagetsi, zvichaderedza zvakanyanya kusvibiswa kwezvakatipoteredza kunokonzerwa nekubviswa kwemabhatiri, uye zvichavhura mazano matsva ekugadzira mabhatiri matsva; chinhu chinonakidza ndechekuti mutengo wetekinoroji iyi wakakura zvikuru - inotarisirwa kuti iite pasi pe10% yemari yese yebhatiri, zvinoreva kuti ine mukana wekushandiswa mubhizinesi rakakura!
Sezvakataurwa nemuongorori Gao Yue: Kungave kuri kuwedzera hupenyu hwebhatiri kana kudzivirira kusiiwa kukuru uye kusvibiswa kwezvakatipoteredza, "kurapa kwakarurama" uku kunopa mhinduro yehunyanzvi inogoneka. Tsvagiridzo iyi haingoratidzi chete simba idzva reChina mumunda wesimba idzva, asiwo inoratidza kusvika kwenguva itsva. Munguva pfupi iri kutevera, "kuzvidya mwoyo nebhatiri" kunogona kuva nhoroondo. Ngatitarirei mberi kushambadzirwa kwetekinoroji iyi inochinja nekukurumidza sezvinobvira!
