Mumakore achangopfuura, mabhatiri e-lithium-ion ave tekinoroji yakakosha mukuchinja kuenda kumasource esimba rinogona kushandiswazve uye mota dzemagetsi (EVs). Kudiwa kuri kuramba kuchiwedzera kwemabhatiri anoshanda uye anodhura zvakakurudzira budiriro huru mumunda uyu. Gore rino, nyanzvi dzinofanotaura kufambira mberi kwakawanda kunogona kuchinja kugona kwemabhatiri e-lithium-ion.
Imwe nzira inoonekwa yekutarisa ndeyekugadzirwa kwemabhatiri e-solid-state. Kusiyana nemabhatiri echinyakare e-lithium-ion anoshandisa ma-electrolyte emvura, mabhatiri e-solid-state anoshandisa zvinhu zvakasimba kana zveceramics sema-electrolytes. Iyi nzira itsva haingowedzere simba, zvichiita kuti EV dziwedzere, asiwo inoderedza nguva yekuchaja uye inovandudza kuchengetedzeka nekuderedza njodzi yemoto. Makambani ane mukurumbira seQuantumscape ari kutarisa mabhatiri e-solid-state lithium-metal, nechinangwa chekuabatanidza mumotokari kutanga muna 2025[1].
Kunyange zvazvo mabhatiri emhando yepamusoro aine vimbiso huru, vaongorori vari kutsvagawo dzimwe nzira dzemakemikari kuti vagadzirise matambudziko pamusoro pekuwanikwa kwezvinhu zvakakosha zvemabhatiri zvakaita se cobalt ne lithium. Kutsvaga nzira dzakachipa uye dzinogara kwenguva refu kuri kuramba kuchikurudzira hunyanzvi. Uyezve, masangano edzidzo nemakambani pasi rese ari kushanda nesimba kuti awedzere mashandiro emabhatiri, kuwedzera kugona, kukurumidzisa kumhanya kwekuchaja, uye kuderedza mari yekugadzira [1].
Kuedza kugadzirisa mabhatiri e lithium-ion kunopfuura mota dzemagetsi. Mabhatiri aya ari kuwana mashandisirwo mukuchengetedza magetsi pagrid-level, zvichibvumira kubatanidzwa kuri nani kwemasimba anowanikwazve nguva nenguva akadai sesimba rezuva nemhepo. Nekushandisa mabhatiri e lithium-ion pakuchengetedza grid, kugadzikana uye kuvimbika kwemasisitimu esimba anowanikwazve kunovandudzwa zvakanyanya [1].
Mukuvandudzwa kwakaitwa munguva pfupi yapfuura, masayendisiti eLawrence Berkeley National Laboratory akagadzira coating yepolymer inofambisa magetsi inozivikanwa seHOS-PFM. Coating iyi inobvumira mabhatiri e lithium-ion anogara kwenguva refu uye ane simba remotokari dzemagetsi. HOS-PFM inotungamira maerekitironi nemaion panguva imwe chete, ichivandudza kugadzikana kwebhatiri, mwero wekuchaja/kuburitsa magetsi, uye hupenyu hwese. Inoshandawo senamira, zvichigona kuwedzera avhareji yehupenyu hwemabhatiri e lithium-ion kubva pamakore gumi kusvika gumi nemashanu. Uyezve, coating iyi yakaratidza kushanda kwakanaka kana ikashandiswa kuma electrodes e silicon ne aluminium, ichideredza kuora kwawo uye ichichengetedza kugona kwemabhatiri kwakakwira mukati menguva dzakawanda. Izvi zvakawanikwa zvine vimbiso yekuwedzera zvakanyanya simba remabhatiri e lithium-ion, zvichiita kuti ave akachipa uye anowanikwa nyore nyore kumotokari dzemagetsi [3].
Sezvo nyika iri kuedza kuderedza kuburitswa kwemagasi anodziya pasi uye kuchinja kuenda kune ramangwana rinogara kwenguva refu, kufambira mberi muhunyanzvi hwemabhatiri e lithium-ion kunoita basa guru. Kutsvagisa kuri kuenderera mberi nekuvandudza kuri kufambisa indasitiri mberi, zvichitiswededza pedyo nemhinduro dzemabhatiri dzinoshanda zviri nani, dzinodhura zvishoma, uye dzine hushamwari kune zvakatipoteredza. Nekubudirira kuri kuita mabhatiri emhando yepamusoro, mamwe makemikari, uye machira akaita seHOS-PFM, mukana wekushandiswa kwemotokari dzemagetsi zvakanyanya uye kuchengetedza simba regrid unowedzera kushanda.
