Tumen: Re na le li-supercapacitor tse kang libeteri tsa lithium-ion. Hantle feela
Khamphani ea Chaena Toomen New Energy e bolela hore e na le li-supercapacitor tse nang le matla a matla a betri ea lithium-ion. Ka nako e ts'oanang, joalo ka li-supercapacitor, li khona ho amohela le ho ntša litefiso tse phahameng ho feta libeteri tsa lithium-ion. Bonyane pampiring, sena se ntlafatsa ts'ebetso ea koloi le ts'ebetso ea ho tjhaja.
Li-Supercapacitor ho fapana le libeteri? Kapa mohlomong papatso?

Li-supercapacitor tseo ho buuoang ka tsona li ile tsa tlisoa Europe ke Belgian Eric Verhulst. Kamoo ho bonahalang kateng, eena ka boeena o ne a sa lumele matla a boletsoeng ke moetsi, hobane a ne a le molemo ka makhetlo a mashome a mabeli ho feta litekanyo tse tšepisitsoeng ke Maxwell. Re eketsa hore Maxwell e ne e le e mong oa baetapele 'marakeng oa supercapacitor mme o ile a rekoa ke Tesla ka selemo sa 2019 (mohloli o moholo).
> Tesla o fumana Maxwell, moetsi oa li-supercapacitor le lisebelisoa tsa motlakase
Verhulst e ithorisa ka hore li-supercapacitor tsa China li ka mamella ho tjhaja ka 50 C (50x capacity), 'me likhoeli tse' maloa ka mor'a ho tjhaja, li ntse li tšoara tefiso hantle, tse sa totobalang haholo ka li-supercapacitor. Ho phaella moo, ba ile ba lekoa ke Univesithi ea Munich, 'me nakong ea liteko tsena ba khona ho mamella mocheso ho tloha ho -50 ho ea ho +45 degrees Celsius.
Moetsi oa Chaena o hatisa hore o sebelisitse "activated carbon" ho li-supercapacitor tsa eona, empa ha ho hlake hore na sena se bolela'ng. Belgian e tlaleha hore Toomen o se a ntse a thehile pakete ea supercapacitor e nang le matla a matla a 0,973 kWh / L. Sena se feta lisele tse tloaelehileng tsa lithium-ion, le ho feta lisele tse tiileng tsa electrolyte tseo Samsung SDI e sa tsoa li hlalosa:
> Samsung e hlahisitse lisele tse tiileng tsa electrolyte. Ho tlosa: ka lilemo tse 2-3 ho tla ba teng 'marakeng
Ho tlalehoa hore li-supercapacitor tse molemo ka ho fetisisa tse tsoang ho moetsi oa Sechaena li fihletse matla a matla a 0,2-0,26 kWh / kg, e leng se bolelang hore li ne li e-na le litekanyo tse seng mpe haholo ho feta libeteri tsa kajeno tsa Li-ion.
Empa ha se phetho. Belgian e hlokomela hore ho na le li-supercapacitor tsa Toomen tse etselitsoeng ho amohela / ho fana ka matla a phahameng haholo. Ba fana ka matla a fokolang a matla (0,08-0,1 kWh / kg), empa ba lumella ho tjhaja le ho lahla ho 10-20 C. Ha ho bapisoa, libeteri tse sebelisoang ho Tesla Model 3 li fana ka matla a matla a fetang 0,22 kWh. boemo ba ho tjhaja betri) ka matla a ho tjhaja a 3,5 C.
Hummingbird e 'ngoe?
Litšepiso tsa Toomen New Energy li shebahala li le ntle haholo pampiring. Litekanyetso tse hlalositsoeng li bontša hore li-supercapacitor tsa moetsi oa Chaena li ka nka sebaka sa libeteri, kapa bonyane li tlatselletsa. Motlakase oa hang-hang o ka fana ka lebelo ka metsotsoana e ka tlase ho 2 kapa ho tjhaja ho tloha ho 500 ho isa ho 1 kW..
Bothata ke hore re sebetsana le litšepiso feela. Nalane e tseba liqapi tse joalo tsa "katleho", tse ileng tsa fetoha leshano. Har'a bona ke libeteri tsa Hummingbird:
