Ha likoloi tsa motlakase (EVs) li ntse li tsebahala lefatšeng ka bophara, tlhoko ea lisebelisoa tse bobebe le tse tiileng tlhahisong ea tsona ea eketseha. Li-alloys tsa aluminium extrusion li hlahile e le phetoho ea papali hoindasteri ea likoloi,kaha li fana ka melemo e mengata joalo ka matla a ntlafatso a sebopeho, phokotso ea boima ba 'mele, le ho eketsa matla a matla. Sengoliloeng sena, re tla hlahloba tse ling tsa ts'ebeliso e ncha ea li-alloys tsa aluminium extrusion ho li-EV, haholo-holo litereneng tsa betri, litšepe tsa tšireletso le literei tsa poleiti ea ho pholisa.

Mohlala, koloi ea motlakase ea Leaf EV ea Nissan Motor Company e ne e sebelisa tšepe ho etsa literei tsa betri, empa e fetotsoe ho aluminium e extruded ka 2018; Volkswagen e 'nile ea e-ba le sebaka se bonolo bakeng sa li-trays tsa tšepe tsa tšepe, empa li-trays tsa eona tse ncha tsa BEV tsa motlakase tsa koloi li boetse li lumellana le Mokhoa ona o lebisitse ho sebelisoa ha aluminium extruded; AkelMittal o ne a entse qeto ea ho sebelisa tšepe e matla haholo bakeng sa sebopeho sa 'mele oa koloi ea Tesla Model 3, empa hamorao o ile a fumana hore 'mele oa mohaho oa tšepe o ne o sa lumellane le khokahanyo ea tray ea betri ea aluminium , kahoo e fetotsoe ho' mele oa motsoako oa aluminium.

Terei e ncha ea ho pholisa ea aluminium

Ka 2018, Setsi sa Theknoloji sa Constellium's Brunel Advanced Solidification Technology se ile sa qapa moralo o mocha oa terei o bitsoang "aluminium e batang", e nang le bokhoni bo matla ba ho pholisa bakeng sa lipakete tsa betri. Ka moralo ona, ha ho sa na tlhoko ea likhokahano tsa welding tsa likhohlano. Liteko li bontšitse hore poleiti e pholileng e kopantsoe ka thata 'me e ke ke ea tsoa,' me ka nako e ts'oanang, ho kopanya ho bonolo ebile ho potlakile.
