Sechikamu chakakosha chemotokari dzemagetsi, mabhatiri e-lithium-ion achakanganisa nharaunda panguva yekushandiswa. Kuti pave neongororo yakazara yemhedzisiro yenharaunda, mapaketi emabhatiri e-lithium-ion, ane zvinhu gumi nerimwe zvakasiyana, akasarudzwa sechinangwa chekudzidza. Nekushandisa nzira yekuongorora hupenyu uye nzira ye entropy weight yekuenzanisa mutoro wenharaunda, sisitimu yekuongorora index yemazinga akawanda yakavakirwa pahunhu hwebhatiri renharaunda inogadzirwa.
Kukurumidza kukura kweindasitiri yekufambisa1 kunoita basa rakakosha mukusimudzira hupfumi nemagariro evanhu. Panguva imwe chete, inoshandisawo mafuta akawanda, zvichikonzera kusvibiswa kwakanyanya kwenharaunda. Sekureva kweIEA (2019), chikamu chimwe muzvitatu cheCO2 inoburitswa pasi rose inobva muchikamu chekufambisa. Kuti kuderedze kudiwa kukuru kwesimba uye mutoro wezvakatipoteredza weindasitiri yekufambisa pasi rose, kuiswa kwemagetsi muindasitiri yekufambisa kunoonekwa seimwe yematanho akakosha ekuderedza kusvibiswa kunosvibisa. Saka, kugadzirwa kwemotokari dzisingakuvadzi nharaunda uye dzinogara kwenguva refu, kunyanya mota dzemagetsi (EVs), kwave sarudzo yakanaka kune indasitiri yemotokari.
Kutanga kubva pachirongwa chemakore mashanu chegumi nemaviri (2010-2015), hurumende yeChina yakasarudza kukurudzira kushandiswa kwemotokari dzemagetsi kuti kufamba kuve kwakachena. Zvisinei, dambudziko guru rezvehupfumi rakamanikidza nyika kutarisana nematambudziko akadai sedambudziko remagetsi, kukwira kwemitengo yemafuta efosi, kushaikwa kwemabasa, kukwira kwemitengo yemafuta, nezvimwewo, izvo zvakakanganisa mafungiro evanhu, kugona kwevanhu kutenga uye kuita sarudzo nehurumende. Saka, kugamuchirwa kushoma uye kugamuchirwa kwemotokari dzemagetsi kunotadzisa kushandiswa kwemotokari dzemagetsi nekukurumidza mumusika.
Kusiyana neizvi, kutengeswa kwemotokari dzinoshandisa mafuta kwakaramba kuchiderera, uye kukura kwenhamba yevaridzi kwakadzikira. Nemamwe mashoko, nekusimbiswa kwemitemo uye kumuka kweruzivo rwezvakatipoteredza, kutengeswa kwemotokari dzemafuta dzemazuva ano kwachinja zvakasiyana nekutengesa kwemotokari dzemagetsi, uye huwandu hwemotokari dzemagetsi huri kuwedzera nekukurumidza. Parizvino, mabhatiri e-lithium-ion (LIB) ndiwo akanakisa mumunda wemotokari dzemagetsi nekuda kwehuremu hwadzo hushoma, kushanda zvakanaka, huwandu hwesimba rakawanda uye simba rakawanda rinobuda. Pamusoro pezvo, mabhatiri e-lithium-ion, sehunyanzvi hukuru hwekuchengetedza mabhatiri, anewo mukana mukuru wekuvandudza simba rinogara kwenguva refu uye kudzikira kukuru kwekuburitswa kwecarbon.
Mukuita kwekusimudzira, mota dzemagetsi dzimwe nguva dzinoonekwa semotokari dzisina kuburitsa mweya, asi kugadzirwa nekushandiswa kwemabhatiri adzo kune simba guru panharaunda. Nekuda kweizvozvo, tsvakiridzo yazvino yakatarisana zvakanyanya nekubatsira kwemotokari dzemagetsi nharaunda. Kune tsvakiridzo yakawanda pamatanho matatu ekugadzira, kushandisa uye kurasa mota dzemagetsi, yakatora matatu emabhatiri e-lithium nickel cobalt manganese oxide (NCM) uye lithium iron phosphate (LFP) anoshandiswa zvakanyanya mumusika wemotokari dzemagetsi wekuChina sechidzidzo uye yakaita ongororo yakakosha yemabhatiri aya matatu zvichibva pakuongorora kwehupenyu (LCA) kwematanho ekugadzira, kushandisa uye kudzokorodza mabhatiri ekubata. Mhedzisiro yacho inoratidza kuti bhatiri re-lithium iron phosphate rine mashandiro ari nani enharaunda kupfuura bhatiri re-triple mumamiriro ese ezvinhu, asi kushanda nesimba muchikamu chekushandisa hakuna kunaka sebhatiri re-triple, uye rine kukosha kwekudzokorodza kwakawanda.
