Ọdịgidere: Ngwaọrụ ejirila sel lithium-ion nwere silicon anodes. Nhọrọ? Ka anyị ghara ikwu okwu

Onye isi ala Sila Nano tweeted na sel lithium-ion nwere silicon anodes abanyela na ngwaọrụ mbụ. Nke a bụ onye na-ahụ maka ahụike Whoop 4.0, nke onye nrụpụta na-ekwu na ọ nwere batrị nwere njupụta ume dị pasenti 17 karịa ngwaọrụ gara aga.

Silicon anodes bụ nke mbụ na obere ngwa ụlọ na n'ọdịnihu, dịka ọmụmaatụ, na Mercedes

Sila Nano achọghị ikpughe paramita nke mkpụrụ ndụ ọhụrụ (voltaji gafee electrodes, njupụta ike zuru oke, wdg). Ọ naghị ekpughe onye kpọmkwem na-eme batrị ahụ n'ihi na Sila Nano bụ naanị onye na-emepụta silicon powder anode na onye ọzọ mere ya. Ya mere, anyị nwere naanị pasent 17 a kpọtụrụ aha na nkwupụta na batrị ọhụrụ pụtara na enwere ike iji sensọ ọhụrụ na otu ndụ batrị mgbe ị na-ebelata olu nke ngwaọrụ site na 1/3 (isi iyi, ohere akwụ ụgwọ; isi iyi).

Anodes cell lithium-ion nke oge a na-eji ụdị carbon dị iche iche, mgbe ụfọdụ yana mgbakwunye silicon. Ihe silicon anode nwere uru na ọ nwere ike ijide ma chekwaa ion lithium ugboro iri karịa graphite anode. N'usoro iwu mgbe ahụ batrị na-eji silicon nwere ike ịnwe okpukpu iri.

Otú ọ dị, nke bụ́ eziokwu adịchaghị mma nye anyị. The elu capacitance nke silicon Ọdịdị pụtara na 1) na mmalite nkebi nke cell na-arụ ọrụ, mgbe a passivation oyi akwa na-mere, ọzọ lithium ion na-enweghị ike imeghari ruo mgbe ebighị ebi. Ma nke a bụ 2) ion lithium na-ekewapụ ihe owuwu silicon karịa (ha ga-adịrịrị ebe), nke na-eduga ná mbibi nke anode. N'ihi ya achọrọ lithium ọzọ iji mee cell silicon anode (= ọnụ ahịa dị elu) Oraz usoro nkwụsi ike ndị ọzọ na-egbochi ọzịza nke nhazi ahụ.

O yiri ka Sila Nano jisiri ike dozie ma ọ dịkarịa ala ụfọdụ n'ime nsogbu ahụ ma n'otu oge ahụ mepụta usoro maka mmepụta nke silicon anodes. N'ime afọ 10 gara aga, usoro mmepụta ejirila ngwa ngwa otu puku ugboro (1 ugboro). Maka sel lithium-ion nwere silicon anodes ịbanye n'ime ụgbọ ala, usoro a dị ugbu a kwesịrị iji ihe 000 (isi iyi) mee ngwa ngwa. Ụlọ ọrụ ahụ na-ebu amụma na n'ime afọ 100-5 na-esote, batrị lithium-ion ga-akụ ahịa na $ 10 kwa awa kilowatt, na-akwado ngwa ngwa ngwa ngwa na na-eguzogide 10 okirikiri, 000 afọ nke ọrụ.

Sila Nano bụ otu n'ime ụlọ ọrụ na-enyere Mercedes (Daimler) aka ịmalite ụlọ ọrụ batrị lithium-ion nke ya.
