IBM yakagadzira masero matsva e-lithium-ion asina cobalt uye nickel. Kurodha kusvika ku80% mumaminitsi mashanu kupfuura 5 kWh / l!
New lithium-ion maseru kubva kuIBM Research Lab. Vanoshandisa "zvinhu zvitatu zvitsva" uye bhatiri rakagadzirwa kubva kwavari rinogona kubhadharisa kusvika 80 muzana musingasviki maminetsi mashanu. Havashandisi cobalt inodhura kana nickel, iyo inogona kuderedza mutengo wemotokari dzemagetsi mune ramangwana.
Zvinhu zvitsva kubva kuIBM: zvakachipa, zvirinani, zvinoshanda zvakanyanya
kare muna 2016, vagadziri vesero uye bhatiri vakapedza 51 muzana yekugadzirwa kwecobalt yenyika.. Mamwe masayendisiti aitarisira kuti kuwedzera kufarira mumotokari dzemagetsi kwaizotungamira kumitengo yakakwira yesimbi iyi, sezvo kuwanikwa kwayo kuri kushoma. Uye izvi zvisinei nekuti makambani mazhinji ari kushanda kuti abvise chinhu ichi kubva kune lithium-ion mabhatiri.
Kukwira kwemitengo yecobalt kuri kuderedza kuderera kwemitengo yemotokari dzemagetsi. Ivo vacharamba vari padyo nedanho razvino:
> Chirevo cheMIT: Mota dzemagetsi hadzizo dhura nekukurumidza sezvaunofunga. Zvakatonyanya kudhura mu2030
ukuwo IBM cell cathodes haina cobalt, nickel uye heavy metal.uye zvinhu zvinoshandiswa mazviri zvinogona kutorwa kubva mumvura yegungwa (tsime).
Sezvo a mari yebhatiri nhasi inenge 1/3 yemutengo wemotokari yemagetsi., zvinhu zvinoumba masero zvakachipa zvinova zvakachipa mutengo wekupedzisira wemotokari yemagetsi yakaderera.
> Yakawanda sei cobalt iri mubhatiri remotokari yemagetsi? [TICHAPINDURA]
Mukuwedzera, vakaishandisa liquid electrolytes ine high flash pointizvo zvingave zvakakosha kana pakaitika tsaona. Uyezve, ma electrolyte emazuva ano anogona kutsva.
IBM inoti yakaedza bhatiri kubva kumaseru ayo akagadzirirwa kutsigira simba repamusoro. Akazviita kuchaja kusvika pa80 muzana mukati memaminitsi asingasviki mashanu. Izvi zvinoreva kumira pachiteshi chekuchajisa kweinenge nguva imwe chete nekuzadza.
Mugadziri anovimbisa kuti masero matsva achabvumira kusikwa kwemabhatiri anoita zviri nani pane ikozvino lithium-ion masero. Semuyenzaniso, vachaunza anopfuura 10 kW parita yebhatiri (10 kW/L) uye vave kutokwanisa kuwana simba remagetsi kupfuura 0,8 kWh / l.
Mukuenzanisa, gore rino CATL yakazvirumbidza kuti chizvarwa chekupedzisira che lithium-ion masero ane nickel-rich cathode yakasvika. 0,7 kWh / l (uye 0,304 kWh/kg). Uye TeraWatt inoti yakagadzira masero eelectrolyte akasimba ane simba re 1,122 kWh/L (uye 0,432 kWh/kg):
> TeraWatt: Tine mabhatiri eelectrolyte akasimba ane simba chairo re0,432 kWh/kg. Inowanikwa kubva 2021
Tsvagiridzo yemasero yakaitwa neIBM yakabatana naDaimler, muridzi weMercedes-Benz brand.

Chinyorwa chekunyora www.elektrowoz.pl: data pakushandiswa kwecobalt muna 2016 kubva kuCobalt Institute. Isu tinoatora nekuti mamiriro acho akawedzeredzwa muzvinyorwa "Zvakazara Kuchajwa" yecobalt. Kunyangwe chiri chokwadi kuti cobalt inoshandiswawo kugadzira mafuta asina kuchena (= kugadzirwa kwemafuta).
Izvi zvinogona kukufadza:
