Nava: Maelectrodes edu e nanotube ane 3 times the capacitance uye anopa ka10 simba mumasero e-lithium-ion.
Svondo idzva, bhatiri idzva. Mugadziri weFrench supercapacitor Nawa anoti atanga kugadzirwa kwemhando nyowani nanotube electrodes yemabhatiri e-lithium-ion. Zvinofungidzirwa kuti nekuda kwekuenderana kurongeka kwe nanotubes, vanogona kuchengetedza zvakapetwa katatu kubhadharisa kupfuura kabhoni anode.
New 3D anodes kubva kuNawa: yakasimba, zvirinani, nekukurumidza, yakasimba
Mazuva ano lithium-ion anode inogadzirwa kunyanya kushandisa graphite kana activated kabhoni (kana kunyange activated kabhoni kubva graphite) nekuti porous chimiro chavo chinobvumira kuchengetwa kweakawanda maion. Dzimwe nguva kabhoni inosanganiswa nesilicon uye yakakomberedzwa nanocoating kudzikamisa kuzvimba kwezvinhu.
Iwe unogona kutonzwa nezve zvigadziriso zvekushandisa yakachena silicon, anodaro Tesla kana Samsung SDI.
> Brand new Tesla maseru: 4680 fomati, silicon anode, "yakanyanya dhayamita", serial kugadzirwa muna 2022.
VaNava vanoti maumbirwo ecarbon akanyanya kuomarara pakufamba. Panzvimbo pekabhoni, kambani inoda kushandisa kabhoni nanotubes, iyo inonzi yave kutoshandiswa mumagadzirirwo makuru emugadziri. Nanotubes akarongedzerwa nenzira yakafanana vertical "notches" paari maion anogona kugara zvakanaka. Chaizvoizvo:
Zvinogona kufungidzirwa kuti ese nanotubes muanode anowanikwa nenzira yekuti ions inofamba zvakasununguka pakati pavo kusvika nzvimbo yakanakira yasarudzwa. "Pasina kudzungaira zvakatenderedza zvimiro zvechinyakare anode, maion anongofamba mashoma nanometer pachinzvimbo che micrometer, sezvazvakaita ne classical electrodes," Nava anodaro.
Chirevo chekupedzisira chinoratidza kuti nanotubes inogonawo kuita semacathodes - basa ravo rinoenderana nechinhu chinenge chiri pamusoro pavo. Nef hairambidze kushandisa silicon nekuti kabhoni nanotubes inoifukidza sekeji, saka chimiro hachizove nemukana wekuzvimba. Dambudziko rekupwanya rakagadziriswa!
> Shandisa kunze-pasherufu lithium-ion masero ane silicon anode. Kuchaja nekukurumidza pane kuwedzera mafuta nehydrogen
Uye zvingave zvakaita sei nemaparamita emasero anoshandisa nanotubes? Zvakanaka, vaizobvumira:
- kushandiswa 10 nguva yakawanda yekuchaja uye yekuburitsa simbachii manje
- zvisikwa mabhatiri ane simba density 2-3 nguva yakakwirira kubva kune vemazuva ano,
- kuwedzera hupenyu hwebhatiri kashanu kana kaguminekuti nanotubes haibvumiri maitiro anoparadza lithium-ion masero (mabviro).
Iwo chaiwo maitiro ekugadzirisa nanotubes mumutsara anofanirwa kunge ari nyore, achinzi ndiyo imwechete nzira inoshandiswa kupfeka magirazi uye masero ephotovoltaic ane anti-reflective coating. Nawa inodada kuti inogona kukura nanotubes anoenderana nekumhanya kusvika ku100 micrometers (0,1 mm) paminiti - uye inoshandisa tekinoroji iyi muma supercapacitor ayo.
Kana zvaitaurwa naNava zvaive zvechokwadi uye maelectrode matsva akatengeswa, izvi zvaizoreva kwatiri:
- mota dzemagetsi dzakareruka pane dzinopisa dzemukati asi dzine huwandu hwakakura,
- kugona kubhadharisa vagadziri vemagetsi nesimba re500 ... 1 ... 000 kW, ipfupi pane refueling,
- kuwedzera kwemamaira evagadziri vemagetsi pasina chikonzero chekutsiva bhatiri kubva ikozvino 300-600 zviuru kusvika 1,5-3-6 mamirioni emakiromita,
- uchichengetedza saizi iripo yebhatiri: rechargeable, toti, kamwe chete mavhiki maviri.
Navah wekutanga shamwari yake iFrench bhatiri inogadzira Saft, iyo iri kubatana nePSA Group neRenault sechikamu cheEuropean Battery Alliance.
