Mumakore achangopfuura, mabhatiri e-lithium-ion akabuda seyakakosha tekinoroji mushanduko yakananga kune anodzoreredzwa magetsi masosi uye mota dzemagetsi (EVs). Iko kudiwa kuri kuramba kuchiwedzera kwemabhatiri anoshanda uye asingadhuri kwakakurudzira budiriro yakakosha mumunda. Gore rino, nyanzvi dzinofanotaura mafambiro akati wandei anogona kushandura kugona kwe lithium-ion mabhatiri.
Imwe budiriro inocherekedza yekuchengeta ziso pakuvandudzwa kwemabhatiri akasimba. Kusiyana nemabhatiri echinyakare e-lithium-ion anoshandisa maelectrolyte emvura, mabhatiri ehurumende anoshandisa zvinhu zvakasimba kana makeramics se electrolytes. Ichi chitsva hachingowedzera kuwanda kwesimba, chinogona kuwedzera huwandu hweEVs, asi zvakare inoderedza nguva yekuchaja uye inovandudza chengetedzo nekudzikisa njodzi yemoto. Makambani ane mukurumbira akaita seQuantumscape ari kutarisa kune yakasimba-state lithium-simbi mabhatiri, aine chinangwa chekuabatanidza mumotokari kutanga kwa2025[1].
Kunyange mabhatiri ehurumende ane chivimbiso chikuru, vatsvakurudzi vari kuongororawo mamwe makemikari kugadzirisa zvinonetsa pamusoro pekuwanikwa kwezvinhu zvakakosha zvebhatiri zvakadai secobalt uye lithium. Kutsvaga zvakachipa, sarudzo dzakasimba kunoenderera mberi nekufambisa hunyanzvi. Uyezve, masangano ezvidzidzo nemakambani pasi rese ari kushanda nesimba kuti awedzere kushanda kwebhatiri, kuwedzera huwandu, kukurumidza kuchaja, uye kuderedza mutengo wekugadzira[1].
Kuedza kukwenenzvera mabhatiri e-lithium-ion anowedzera kupfuura mota dzemagetsi. Aya mabhatiri ari kuwana maapplication mugridi-level magetsi ekuchengetedza, achibvumira kubatanidzwa zvirinani kwepakati penguva inodzokororwa magetsi solar nemhepo simba. Nekushandisa mabhatiri e-lithium-ion ekuchengetedza grid, kugadzikana uye kuvimbika kwesimba rinodzoreredzwa masisitimu anovandudzwa zvakanyanya[1].
Mukubudirira kuchangoburwa, masayendisiti kuLawrence Berkeley National Laboratory akagadzira conductive polymer coating inozivikanwa seHOS-PFM. Uku kupfekedza kunogonesa kugara kwenguva refu, ane simba rakawanda relithium-ion mabhatiri emotokari dzemagetsi. HOS-PFM panguva imwe chete inoitisa ese maerekitironi nemaion, ichiwedzera kugadzikana kwebhatiri, kubhadharisa / kuburitsa mitengo, uye hupenyu hwese. Inoshandawo seanonamira, inogona kuwedzera avhareji yehupenyu hwemabhatiri e-lithium-ion kubva ku10 kusvika kumakore gumi nemashanu. Uyezve, iyo yekupfekedza yakaratidza kuita kwakasarudzika kana ikaiswa kune silicon uye aluminiyamu maelectrode, kudzikamisa kuderera kwavo uye kuchengetedza yakakwira bhatiri huwandu pamusoro peakawanda kutenderera. Izvi zvakawanikwa zvine vimbiso yekuwedzera zvakanyanya kuwanda kwesimba remabhatiri e-lithium-ion, zvichiita kuti zvive nyore uye zviwanikwe kumotokari dzemagetsi[3].
Sezvo nyika inoyedza kudzikisa kuburitswa kwegasi regreenhouse uye shanduko kuenda kune remangwana rakagadzikana, kufambira mberi mu lithium-ion bhatiri tekinoroji inoita basa rakakosha. Iko kuenderera mberi kwekutsvagisa nekusimudzira kuedza kuri kufambisa indasitiri mberi, zvichitiswededza padhuze nezvinoita, zvinokwanisika, uye zvine hushamwari bhatiri mhinduro. Nekubudirira mumabhatiri akasimba-nyika, mamwe machemistries, uye machira seHOS-PFM, mukana wekugamuchirwa kwemotokari dzemagetsi uye giredhi-level rekuchengetedza simba rinowedzera kuitika.
