Tumen: Isu tine supercapacitors senge lithium-ion mabhatiri. Zvirinani chete

26.05.2022 /

Kambani yekuChina yeToomen New Energy inoti ine ma supercapacitor ane simba rekushomeka kwemabhatiri e-lithium-ion. Panguva imwecheteyo, sema supercapacitor, vanokwanisa kubvuma uye kuburitsa machaji akakwira kupfuura mabhatiri e-lithium-ion. Zvirinani pamapepa, izvi zvinovandudza mashandiro emotokari uye kuita kwekuchaja.

Supercapacitors pane mabhatiri? Kana kuti pamwe kushambadzira?

Tafura yezvinyorwa

  • Supercapacitors pane mabhatiri? Kana kuti pamwe kushambadzira?
    • Imwe Hummingbird?

Iwo ma supercapacitor ari mubvunzo akaunzwa kuEurope neBelgian Eric Verhulst. Sezviri pachena, iye pachake haana kutenda mukukwanisa kwakaziviswa nemugadziri, nokuti vakanga vari nani kakapetwa makumi maviri kupfuura maparameter akavimbiswa naMaxwell. Isu tinowedzera kuti Maxwell aive mumwe wevatungamiriri mumusika we supercapacitor uye akatengwa naTesla muna 2019 (mabviro).

Verhulst anozvikudza kuti maChinese supercapacitors anogona kumira kuchaja pa50 C (50x simba), uye mwedzi mishoma mushure mekuchaja, ivo vachiri kubata kuchaja zvakanaka, izvo zvisiri pachena zvakanyanya nema supercapacitors. Pamusoro pezvo, vakaedzwa neYunivhesiti yeMunich, uye panguva yebvunzo idzi vakakwanisa kutsungirira tembiricha kubva -50 kusvika +45 degrees Celsius.

Mugadziri weChinese anosimbisa kuti yakashandisa "activated kabhoni" mune yayo supercapacitors, asi hazvizivikanwe kuti izvi zvinorevei. The Belgian inoshuma kuti Toomen akatogadzira packet supercapacitor ine simba density ye0,973 kWh / L. Izvi zvakanyanya kudarika zvakajairika lithium-ion masero, uye zvakatonyanya kupfuura prototype yakasimba electrolyte masero ayo Samsung SDI ichangobva kutsanangurwa:

Zvinonzi yakanakisa supercapacitors kubva kumugadziri weChinese yakasvika kune simba density ye 0,2-0,26 kWh / kg, izvo zvinoreva kuti vaive nemaparameter asina kushata kupfuura emazuva ano mabhatiri eLi-ion.

Asi handizvo zvoga. Iyo Belgian inocherekedza kuti kune Toomen supercapacitors yakagadzirirwa kugamuchira / kuburitsa masimba akakwira zvakanyanya. Vanopa yakaderera simba density (0,08-0,1 kWh / kg), asi kubvumira kuchaja uye kuburitsa pa10-20 C. Mukuenzanisa, mabhatiri anoshandiswa muTesla Model 3 anopa simba rinopfuura 0,22 kWh./ ​​kg (pamu. bhatiri yekuchaja level) ine simba rekuchaja re3,5 C.

Imwe Hummingbird?

Zvivimbiso zveToomen New Energy zvinotaridzika zvakanaka pabepa. Iwo akatsanangurwa ma paramita anoratidza kuti iwo ma supercapacitors emugadziri weChinese anogona kutsiva mabhatiri, kana kuti awedzere iwo. Pakarepo simba rinobuda rinogona kupa kukurumidza musingasviki 2 masekonzi kana kuchaja kubva pa500 kusvika pa1 kW..

Dambudziko nderekuti tinongotarisana nezvivimbiso. Nhoroondo inoziva "kubudirira" kwakadai zvigadzirwa, izvo zvakazove zvenhema. Pakati pavo pane mabhatiri eHummingbird:
