Kahoo, ntoa! Tesla: likarolo tsa cylindrical feela, 4680. Volkswagen: likarolo tse lekanang tsa mahlakore a mabeli

Nakong ea Letsatsi la Battery ka Mphalane 2020, Tesla o phatlalalitse ho theoa ha fomate e ncha ea cylindrical cell, 4680, e tla fumaneha haufinyane moleng oa eona oa koloi. Likhoeli tse ts'eletseng hamorao, Volkswagen e ile ea phatlalatsa likhokahano tse tloaelehileng tsa cube tse neng li tla fetoha motheo oa hoo e ka bang sehlopha sohle, ho kenyeletsoa le literaka.

Volkswagen e ntse e ts'oara, e etsa lilemo tse 2-3 feela ho bapisoa le Tesla

Lethathamo la tse kahare

• Volkswagen e ntse e ts'oara, e etsa lilemo tse 2-3 feela ho bapisoa le Tesla
  • See sohle se bolela eng ho bamameli ba tloaelehileng?

Mefuta e meraro ea lisele e sebelisoa hajoale likoloing tsa motlakase:

• cylindrical (sebopeho sa cylindrical) se sebelisoang haholo ke Tesla,
• khutlonnetsepa (eng. prismatic), mohlomong e tloaelehileng ka ho fetisisa har'a baetsi ba setso, o ile a etsa qeto ea ho etsa sena Sehlopha sa Volkswagen ka hare ho "sele e le 'ngoe",
• sachet (mokotla), e hlahang moo ntho ea bohlokoa ka ho fetisisa e leng ho "petetsa" matla a betri ka hohle kamoo ho ka khonehang ho tsoa boemong bo fanoeng.

E 'ngoe le e' ngoe ea mefuta ena e na le melemo le melemo ea eona: cylindrical e kile ea e-ba tse ratoang ka ho fetisisa (li ne li sebelisoa lik'hamera le li-laptops), kahoo Tesla le Panasonic ba khethehileng ho tsona. Li boetse li tiisa boemo bo phahameng ba tšireletso. Sachet ba lumella matla a matla a matla hore a finyelloe, empa baqapi ba tlameha ho hlokomela hore ba ka eketsa molumo haholo kaha ha ba na masoba a ho lokolla likhase leha e le life tse ka khonehang. Li-cuboids Tsena ke likahare tsa mekotla e ka har'a mokotla o thata; tsela e bonolo ka ho fetisisa ea ho li kopanya (mohlala, ho tloha li-blocks) ke betri e entsoeng hantle, hape e tšoarella haholoanyane ka mochini.

Volkswagen e se e ntse e sebelisa lisele tse khutlonnetsepa, empa ho bonahala eka sebopeho sa bona bonyane se ikamahanya le moralo oa koloi. Lisele tse le 'ngoe li lokela ho hlaha ka lekhetlo la pele ka 2023, 'me ka 2030 li lokela ho etsa karolo ea 80 lekholong ea lisele tse sebelisoang:

Lisele tse ncha li ke ke tsa hlophisoa ka li-module (ho tloha seleng ho ea ho sephutheloana), le sebopeho se tšoanang (sebopeho) se tlameha ho ba le mefuta e fapaneng ea k'hemistri ka hare:

• ka lihlahisoa tse ngata tla sebetsa lisele tse nang le manganese (le nickel)
• mefuteng e khethiloeng hlaha Lisele tsa NMC (li-nickel-manganese-cobalt cathodes),
• ... 'me ho phaella ho tsena, Volkswagen e boetse e na le lisele tse tiileng tsa electrolyte kelellong, kaha e na le karolo ea 25% ea QuantumScape. Lisele tse tiileng tsa 'muso li se li ntse li lumella keketseho ea 30% le tefiso ka metsotso e 12 ho fapana le 20 (data e ipapisitseng le lipapiso):

Qetellong, Volkswagen e batla ho sebelisa likhokahano joalo ka likarolo tsa sebopeho sa koloi (ho tloha seleng ho ea ho mochini) mme ho bonahala eka lisele tse emeng li tla ikamahanya le sena.
