Musi waGunyana 27, 2024, paNyika ye2024Motokari Itsva Yemagetsi Musangano, BYD Chief Scientist uye Chief Automotive Injiniya Lian Yubo akapa ruzivo mune ramangwana rehunyanzvi hwebhatiri, kunyanya.yakasimba-state mabhatiri. Akasimbisa kuti kunyange zvakadaroBYDakaita zvikurukufambira mberi mundima iyi, zvinotora makore akati wandei mabhatiri ehurumende asati ashandiswa zvakanyanya. Yubo inotarisira kuti zvichatora makore matatu kusvika mashanu kuti mabhatiri aya ave akakurumbira, aine makore mashanu ari echokwadi nguva yakatarwa. Uku kungwarira kwetarisiro kunoratidza kuoma kweshanduko kubva kune echinyakare mabhatiri e-lithium-ion kuenda kune akasimba-state mabhatiri.
Yubo yakaratidza matambudziko akati wandei akatarisana neiyo solid-state bhatiri tekinoroji, kusanganisira mutengo uye kudzora zvinhu. Akacherekedza kuti lithium iron phosphate (LFP) mabhatiri haafanire kubviswa mukati memakore gumi nemashanu kusvika makumi maviri anotevera nekuda kwenzvimbo yavo yemusika uye mutengo-unoshanda. Pane zvinopesana, anotarisira kuti mabhatiri ehurumende anonyanya kushandiswa mumhando dzepamusoro-soro mune ramangwana, nepo lithium iron phosphate mabhatiri acharamba achishumira maitiro akaderera. Iyi nzira mbiri inobvumira hukama hwekusimbisana pakati pemhando mbiri dzebhatiri kuti dziite zvikamu zvakasiyana zvemusika wemotokari.
Iyo indasitiri yemotokari iri kusangana nekuwedzera mukufarira uye kudyara mune yakasimba-state bhatiri tekinoroji. Vagadziri vakuru vakaita seSAIC neGAC vakazivisa zvirongwa zvekuwana kugadzirwa kwakawanda kwemabhatiri akasimba-senyika kutanga 2026. Iyi nguva inoisa 2026 segore rakakosha mukushanduka kwehunyanzvi hwebhatiri, zvichiratidza shanduko inogona kuitika mukugadzirwa kwehuwandu. yemabhatiri akasimba-akasimba. Solid-state bhatiri tekinoroji. Makambani akadai seGuoxuan Hi-Tech nePenghui Energy akarondedzerawo zvakatevedzana kubudirira mundima iyi, zvichisimbisa kuzvipira kweindasitiri kusimudzira tekinoroji yebhatiri.
Solid-state mabhatiri anomiririra kusvetuka kukuru kumberi mubhatiri tekinoroji kana ichienzaniswa neyekare lithium-ion uye lithium-ion polymer mabhatiri. Kusiyana nevakatangira, mabhatiri ehurumende anoshandisa maelectrode akasimba uye akasimba maelectrolyte, ayo anopa akawanda mabhenefiti. Iyo theoretical simba density yeakasimba-state mabhatiri anogona kudarika zvakapetwa kaviri eiyo yakajairwa lithium-ion mabhatiri, zvichiita kuti ive inomanikidza sarudzo yemagetsi mota (EVs) inoda yakakwirira simba rekuchengetedza simba.
Pamusoro pekuva nepamusoro pesimba density, mabhatiri e-solid state zvakare akareruka. Kudzikiswa kwehuremu kunokonzerwa nekubviswa kwekutarisa, kutonhora uye masisitimu ekudzivirira anowanzo kudiwa kune mabhatiri e-lithium-ion. Iyo yakareruka huremu haingonatsiridza kugona kwese kwemotokari, inobatsirawo kuvandudza mashandiro uye huwandu. Pamusoro pezvo, mabhatiri ehurumende akagadzirirwa kuchaja nekukurumidza uye kugara kwenguva refu, kugadzirisa nyaya mbiri dzinokosha dzevashandisi vemotokari yemagetsi.
Thermal kugadzikana ndeimwe yakakosha mukana weakasimba-state mabhatiri. Kusiyana neyakajairwa mabhatiri e-lithium-ion, ayo anotonhora patembiricha yakaderera, mabhatiri ehurumende akasimba anogona kuchengetedza kuita kwavo pane yakafara tembiricha. Ichi chiitiko chinonyanya kukosha munzvimbo dzine mamiriro ekunze akanyanyisa, kuve nechokwadi kuti motokari dzemagetsi dzinoramba dzakavimbika uye dzakabudirira pasinei nekupisa kwekunze. Pamusoro pezvo, mabhatiri ehurumende anoonekwa akachengeteka kupfuura mabhatiri e-lithium-ion nekuti haanyanyi kutarisana nemapfupi maseketi, dambudziko rinowanzoitika rinogona kukonzeresa kutadza kwebhatiri uye njodzi dzekuchengetedza.
Nharaunda yesainzi iri kuwedzera kuziva mabhatiri ehurumende seimwe nzira inoshanda kune mabhatiri e-lithium-ion. Iyo tekinoroji inoshandisa musanganiswa wegirazi wakagadzirwa ne lithium uye sodium sechinhu chinoitisa, kutsiva iyo yemvura electrolyte inoshandiswa mumabhatiri akajairwa. Uku kutsva kunowedzera zvakanyanya kuwanda kwesimba remabhatiri e-lithium, zvichiita kuti yakasimba-state tekinoroji itarise kutsvaga nekusimudzira mune ramangwana. Sezvo indasitiri yemotokari ichiramba ichishanduka, kubatanidzwa kwemabhatiri ehurumende-akasimba anogona kutsanangura patsva mamiriro emotokari yemagetsi.
Zvese mune zvese, kufambira mberi mune yakasimba-state bhatiri tekinoroji inovimbisa ramangwana rakajeka reindasitiri yemotokari. Kunyange zvipingamupinyi zvichiripo maererano nemutengo uye kudzora kwezvinhu, zvisungo kubva kuvatambi vakuru vakaita seBYD, SAIC neGAC zvinoratidza kutenda kwakasimba mukugona kwemabhatiri ehurumende. Sezvo gore rinonetsa ra2026 rasvika, indasitiri yakagadzirira mabhindauko makuru anogona kuumbazve mafungire atinoita nezvemagetsi emagetsi ekuchengetedza simba. Iko kusanganiswa kwehuwandu hwesimba repamusoro, huremu huremu, kukurumidza kuchaja, kugadzikana kwemafuta uye kuchengetedzeka kwakawedzera kunoita kuti mabhatiri ehurumende ive muganhu unonakidza mukutsvaga zvigadziriso zvekufambisa uye zvinoshanda.
