Pakuburitswa kwechigadzirwa chitsva musi wa28 Nyamavhuvhu, Penghui Energy yakazivisa zvikuru zvinogona kuchinja indasitiri yekuchengetedza simba. Kambani iyi yakatanga bhatiri rayo rekutanga rechizvarwa chose, iro rakarongerwa kugadzirwa kwakawanda muna 2026. Nesimba re20Ah, bhatiri iri idzva rinotarisirwa kusangana nekudiwa kuri kukura kwemhinduro dzekuchengetedza simba dzinoshanda uye dzinogara kwenguva refu.
Kuburitswa kwebhatiri rePenghui Energy rakasimba chose kunoratidza danho rakakosha mukuvandudzwa kwetekinoroji yekuchengetedza simba. Kusiyana netsika dzechinyakare.mabhatiri e lithiamu, iyo inoshandisa ma electrolyte emvura kana ejeli, mabhatiri emhando dzose anoshandisa ma electrolyte akasimba. Dhizaini iyi inopa zvakanakira zvakawanda, zvinosanganisira kuchengetedzeka kwakawedzerwa, huwandu hwakawanda hwesimba, uye hupenyu hwenguva refu hwekutenderera. Nekuda kweizvozvo, mabhatiri aya ane mukana wekupa simba kune akasiyana mashandisirwo, kubva kumagetsi emagetsi kusvika kumotokari dzemagetsi uye masisitimu ekuchengetera simba egrid-scale.
Kubudirira kuri kuitika mumunda wemabhatiri emhando yepamusoro
Pamusangano wevatori venhau, Penghui Energy yakazivisa zvinhu zviviri zvikuru zviri kuitika munyaya dzemabhatiri emhando ye solid-state: kuvandudzwa kwemaitiro uye kugadziriswa kwemagadzirirwo ehurongwa hwezvinhu, izvo zvakagadzirisa matambudziko ehunyanzvi hwe oxide solid electrolyte technology.
Panyaya yekuvandudza mashandiro, Penghui Energy yakazvigadzira yega nzira yakasiyana yekuputira electrolyte wet coating. Maitiro aya anobudirira kupfuura maitiro ekupisa zvakanyanya e oxide solid electrolytes, anodzivirira kuputsika kwezvinhu zveceramic, uye anoita kuti maitiro acho ave nyore.
Mutengo wemabhatiri akasimba anoshandisa nzira iyi unotarisirwa kunge wakakwira ne15% chete kupfuura mutengo wemabhatiri emazuva ano.mabhatiri e lithiamu.
Penghui Energy yakati mumakore matatu kusvika mashanu anotevera, nekugadziriswa kuri kuitwa uye kuvandudzwa kwemaitiro aya pamwe nekuderedzwa kwemitengo yezvinhu, mutengo wemabhatiri ayo akasimba unotarisirwa kuenzana nemabhatiri emhando yelithium.
Panyaya yekuvandudzwa kwezvinhu, bhatiri rePenghui Energy rinoshandisa jira remagetsi rakagadzirwa rakazvimiririra. Kuwedzera kune oxide electrolytes, jira iri remagetsi rinosanganisawo zvinhu zvakakosha zvakaita sezvishandiso zvitsva zvemagetsi zvisina kugadzirwa uye zvimwe zvinhu zvinoshanda.
Iyi nzira itsva inovandudza hunhu hweceramics husina kusimba kana yakakotama, inowedzera kunamira uye kupfava kwe electrolyte layer, uye inoderedza zvikuru mukana wekuti mabhatiri e solid-state ashande mukati me electrolyte layer ashande zvakanaka. Panguva imwe chete, inovandudzawo ionic conductivity ye inorganic composite electrolyte layer, inoderedza kuramba kwemukati kwe bhatiri, uye inowedzera kuvandudza kupisa uye mashandiro ekuchengetedza ebhatiri re solid-state.
Zvakanakira mabhatiri emhando dzose
Chimwe chezvakanakira zvikuru zvemabhatiri akasimba zvachose ndechekuchengetedzeka kwawo kwakanyanya. Kusiyana neakajairikamabhatiri e lithiamu, iyo inoshandisa ma electrolyte emvura anobvira moto, mabhatiri emhando dzose anoshandisa ma electrolyte akasimba. Izvi zvinobvisa njodzi yekubuda kwemvura uye kupisa, zvichiita kuti zvive zvakachengeteka kushandisa mumhando dzakasiyana-siyana, kusanganisira mota dzemagetsi uye nzvimbo yekuchengetedza simba remagetsi.
Pamusoro pekuchengetedzeka, mabhatiri akasimba anopa simba rakawanda. Izvi zvinoreva kuti anogona kuchengetedza simba rakawanda mupakeji diki, rakareruka, zvichiita kuti akwanise kushandiswa mumagetsi anotakurika nemotokari dzemagetsi. Simba rakawanda rinorevawo kuti bhatiri rinogara kwenguva refu, kuderedzwa kwekuchaja, uye pakupedzisira kuvandudza kushanda zvakanaka kwehurongwa hwekuchengetera simba.
Pamusoro pezvo, mabhatiri emhando yepamusoro anoratidza kushanda zviri nani pakupisa kwakanyanya. Mabhatiri echinyakare anogona kutadza kushanda zvakanaka kana kutokundikana kana akasangana nekupisa kwakanyanya kana kutonhora, asi mabhatiri emhando yepamusoro anonyatsotsungirira mamiriro ezvinhu aya. Izvi zvinoita kuti akwanise kushandiswa munzvimbo dzakasiyana-siyana, kusanganisira kuongorora muchadenga uye kushandiswa kwemauto.
Imwe mukana wemabhatiri akasimba chete ndeyekuti anogona kuchaja nekukurumidza. Maelectrolyte akasimba anobvumira kutakurwa kwemaion nekukurumidza kana tichienzanisa nemabhatiri echinyakare, zvichibvumira nguva yekuchaja nekukurumidza. Izvi zvinogona kukanganisa zvakanyanya kushandiswa kwemotokari dzemagetsi uye kubatanidzwa kwesimba rinogona kuvandudzwa mugrid.
Uyezve, mabhatiri akasimba chete haakuvadzi nharaunda zvakanyanya. Haana zvinhu zvine chepfu uye zvinobvira moto zvinowanikwa mumabhatiri echinyakare, zvichideredza njodzi yekusvibiswa kwenharaunda uye kudiwa kwenzira dzakakosha dzekurasa.
Mhedziso
Kuburitswa kwemabhatiri ePenghui Energy akasimba chose kunouya panguva iyo kudiwa kwemhinduro dzepamusoro dzekuchengetedza simba kuri kukurumidzirwa kupfuura kare. Sezvo nyika iri kuchinja kuenda kune ramangwana rakasimba uye rine magetsi, kudiwa kwetekinoroji yekuchengetedza simba inoshanda zvakanyanya, yakachengeteka uye yakavimbika kuri kuramba kuchikura. Mabhatiri esimba chose chose ane mukana wekuzadzisa zvinodiwa izvi uye anoita basa guru mukuumba ramangwana rekuchengetedza simba.
Kana muine mibvunzo kana kuti muchida kuziva zvakawanda, musazeza kupindurataura nesu.
