China yakakunda dambudziko guru remotokari dzemagetsi here? Rudzi rutsva rwebhatiri reMupi rinopa kukurumidza kuchaja nguva asi ipfupi
Kambani yeChinese tekinoroji CATL yakaburitsa chizvarwa chekutanga sodium-ion bhatiri.
Tesla naElon Musk vanogona kunge vakaburitsa gumbeze remagetsi kubva pasi pavo mushure mekunge kambani yeChinese tekinoroji CATL yazivisa budiriro muhunyanzvi hwebhatiri iyo yaigona kuona vagadziri vemotokari vachiisa pamberi pemabhatiri e-lithium-ion vachifarira mabhatiri e-sodium-ion.
Kambani yekuChina yekutsvagisa nekusimudzira yeContemporary Amperex Technology (CATL) yakaburitsa bhatiri rekutanga resodium-ion nemusi weChina. Nhau huru, maererano neCATL, ndeyokuti yakakunda zvikanganiso izvo zvino zvinodzivirira tekinoroji yebhatiri yesodium kubva pakuva simba rinoshanda.
Mabhatiri e-sodium-ion anoshanda zvakanyanya kufanana neawo e-lithium-ion, ane zvimedu zvakajairwa zvinoyerera pakati pecathode neanode. Kusvika pari zvino, mabhatiri e-sodium-ion akakanganiswa nekushomeka kwesimba, izvo zvinoreva kuti anogona kugara kwenguva yakareba sei asati achajiswa, izvo zvinokanganisa huwandu hwemotokari yemagetsi.
Panewo dambudziko rekunonoka kuchaja kwakabatana nemabhatiri esodium. Izvi ndizvo zvikonzero zvikuru nei mabhatiri e-lithium-ion ave akakurumbira pamusoro peaya sodium.
Lithium-ion mabhatiri ane nyaya dzawo, sekupisa kwaanogadzira uye kusadzivirirwa kwekutonhora. Iyo lithium mining process inodhura zvakare uye inoda mvura yakawanda kuti ishandiswe. Kuwanda kwesodium muvhu uye nyore kuchekwa kunoita kuti rive imwe nzira inokwanisika.
Ikozvino CATL inoti yakagadzirisawo kuwanda kwesimba uye matambudziko ekuchaja emabhatiri e-sodium-ion.
"CATL sodium-ion battery cell ine simba rinosvika 160Wh / kg, uye bhatiri rinogona kubhadharwa mumaminitsi gumi nemashanu kusvika ku15% SOC pakupisa kwekamuri," kambani yakadaro mukutaura.
"Kunyanya, pasi pekushisa kwakadzika kwe -20 ° C, bhatiri ye-sodium-ion inoramba iine simba rinopfuura 90%, uye maitiro ayo ekubatanidza maitiro anogona kusvika kupfuura 80%.
CATL yakakwanisa kuita izvi muchidimbu nekushandura cathode zvinhu.
"Kune ma cathode zvinhu, CATL yakashandisa PW zvinhu zvine yakakwira chaiyo capacitance uye yakashandura huwandu hwakawanda hwezvinhu nekugadzirisa maerekitironi, izvo zvakagadzirisa dambudziko repasi rose rekuderera nekukurumidza panguva yebhasikoro," mushumo wakadaro.
"Kune anode zvinhu, CATL yakagadzira yakaoma kabhoni zvinhu zvine yakasarudzika porous chimiro chinopa kuchengetedza kwakawanda uye nekukurumidza kufamba kwemaion sodium, pamwe nekuita kutenderera kunoshamisa."
Mune izvo zvino nhangemutange yemaoko ebhatiri, Tesla ari kuita zvese zvaanogona kusimudzira tekinoroji yelithium-ion. Current Model 3 lithium-ion mabhatiri ane simba density inosvika 260 Wh/kg.
Kunyange zvazvo izvi zviri pamusoro pe160 Wh / kg yebhatiri itsva ye-sodium-ion, vanocherechedza unyanzvi vanoziva kuti bhatiri reCATL rinongova muchizvarwa chekutanga. Iko kukurumidza kumhanya kwekusimudzira kunogona kukonzera kuwedzera kunoshamisa kwesimba remagetsi uye nguva yekuchaja uchichengeta mitengo yakaderera.
Ko Elon achaita sei? Zvakanaka, gore rapfuura chete, akazivisa kuti mabhatiri ari kushanda naTesla parizvino achakwanisa kupa 50% yakawanda simba density panosvika 2024.
Mujaho watanga.
