Ukuqina: Idivayisi isivele isebenzisa amaseli e-lithium-ion ane-silicon anode. Izinketho? Asikhulume
Umongameli kaSila Nano ubhale kuTwitter ukuthi amaseli e-lithium-ion ane-silicon anode asanda kufika emshinini wokuqala. Lesi isilandeleli sokufaneleka se-Whoop 4.0, umkhiqizi athi sinebhethri elinamaphesenti angu-17 ukuminyana kwamandla aphezulu kunedivayisi yangaphambilini.
I-Silicon anode ingeyokuqala ezintweni zasendlini ezincane futhi esikhathini esizayo, isibonelo, eMercedes
USila Nano akafuni ukudalula imingcele yamaseli amasha (i-voltage kuwo wonke ama-electrode, ukuminyana kwamandla okuphelele, njll.). Futhi akuvezi ukuthi ubani ngempela owenza amabhethri ngoba uSila Nano ungumkhiqizi we-silicon powder anode kuphela futhi amaseli enziwe omunye umuntu. Ngakho-ke sinamaphesenti angu-17 kuphela ashiwo kanye nesimangalo sokuthi amabhethri amasha asho ukuthi izinzwa ezintsha zingasetshenziswa kanye nempilo yebhethri efanayo kuyilapho kunciphisa ivolumu yedivayisi ngo-1/3 (umthombo, ukufinyelela okukhokhelwayo; umthombo).
I-lithium-ion cell anode yesimanje isebenzisa izinhlobo ezahlukahlukene zekhabhoni, kwesinye isikhathi ngokufakwa kwe-silicon. I-silicon anode inenzuzo yokuthi ingakwazi ukubamba futhi igcine i-lithium ion ephindwe ka-10 kune-graphite anode. Ngokwethiyori ke ibhethri esebenzisa i-silicon ingaba nomthamo ophindwe ka-10.
Nokho, iqiniso alisilungele neze. Amandla aphezulu wesakhiwo se-silicon asho ukuthi 1) esigabeni sokuqala sokusebenza kweseli, lapho ungqimba lwe-passivation lwenziwa, ama-ion e-lithium amaningi awanyakazi unomphela. Futhi lokhu kungu-2) i-lithium ions ihlukanisa izakhiwo ze-silicon kakhulu (kumele zibekwe endaweni ethile), okuholela ekubhujisweni kwe-anode. Ngenxa yalokho i-lithium eyengeziwe iyadingeka ukwenza iseli ye-silicon anode (= inani eliphakeme) Oraz izindlela ezengeziwe zokuzinza ezivimbela ukuvuvukala kwesakhiwo.
Kubonakala sengathi uSila Nano ukwazile ukuxazulula okungenani ezinye zezinkinga futhi ngesikhathi esifanayo wakha indlela yokukhiqiza ngobuningi be-silicon anode. Eminyakeni eyi-10 edlule, inqubo yokukhiqiza iye yashesha izikhathi eziyinkulungwane (izikhathi ezi-1). Ukuze amaseli e-lithium-ion ane-silicon anode angene ezimotweni, inqubo yamanje idinga ukusheshisa nge-factor 000 (umthombo). Le nkampani ibikezela ukuthi eminyakeni eyi-100-5 ezayo, amabhethri e-lithium-ion azofika emakethe ngama-dollar ayi-10 ngehora le-kilowatt-ihora, asekele ukushaja okusheshayo futhi imelana nemijikelezo eyi-10, iminyaka eyi-000 yokusebenza.
ISila Nano ingenye yezinkampani ezisiza iMercedes (Daimler) ukuthi yethule eyayo izimboni zamabhethri e-lithium-ion.
Lokhu kungase kube nentshisekelo kuwe:
