Ke eng e kenyelletsoeng ka betri ea lithium-ion e tsoang koloing ea motlakase? Lithium e kae, cobalt e kae? Karabo ke ena
Volkswagen Group Components e phatlalalitse chate e bonts'ang likarolo tsa betri ea koloi ea motlakase e thehiloeng ho [lithium] nickel-cobalt-manganese cathodes. Ena ke mofuta o tummeng ka ho fetisisa oa sele 'marakeng, kahoo lipalo li emela haholo.
Betri ea moetsi oa motlakase: 8 kg lithium, 9 kg cobalt, 41 kg nickel.
Mohlala e ne e le betri ea mohlala e boima ba lik'hilograma tse 400, i.e. matla a 60-65 kWh. Hoa etsahala hore boholo ba boima ba eona (126 kg, karolo ea 31,5 lekholong) ke Aluminium likotlolo tsa lijana le li-module. Ha ho makatse: e sireletsa betri hore e se ke ea senyeha, kahoo e tlameha ho tšoarella.
Palo e nyane ea aluminium (foil ea aluminium) e boetse e hlaha ho li-electrode. E sebeletsa ho lokolla mojaro ka ntle ho sele.
Ea bobeli e boima ka ho fetisisa motsoako ke graphite (71 lik'hilograma, 17,8%), eo anode e entsoeng ho eona. Lithium e bokellana sebakeng se masoba sa graphite ha betri e tjhajoa. 'Me e ea tsoa ha betri e tsoa.
Ntho ea boraro e boima ka ho fetisisa ke nikele (41 lik'hilograma, 10,3%), e leng ntho e ka sehloohong, ho phaella ho lithium, cobalt le manganese, bakeng sa ho thehoa ha li-cathodes tsa morao-rao. Manganese lik'hilograma tse 12 (liperesente tse 3), cobalt ho na le le ho feta, hobane 9 lik'hilograma (liperesente tse 2,3), 'me senotlolo se ka betri mmala - 8 lik'hilograma (2 lekholong).
Cobalt cube e nang le moeli oa 1 centimeter. Re sebelisitse foto ena pele ho bala litaba tsa cobalt tsa betri ea koloi ea motlakase. Joale hoo e ka bang 10 kg e ile ea tsoa, e batlang e le e loketseng. (C) Alchemist-hp / www.pse-mndelejew.de
Koporo boima ba lik’hilograma tse 22 (liperesente tse 5,5) ’me mosebetsi oa eona ke ho tsamaisa motlakase. Hanyane hanyane polasetiki, moo lisele, lithapo, li-connectors li koetsoeng, 'me li-modules li koaletsoe nyeoeng - lik'hilograma tse 21 (karolo ea 5,3 lekholong). Mokelikeli motlakase, moo li-ion tsa lithium li tsamaeang pakeng tsa anode le cathode, li etsa boima ba lik'hilograma tse 37 (karolo ea 9,3 lekholong) ea boima ba betri.
Na elektroniki ke 9 lik'hilograma (2,3 lekholong), ka e ile ea fetoha, eo ka linako tse ling e sebelisoang ka lipoleiti tse matlafatsang tse eketsehileng kapa ka foreimi, ke lik'hilograma tse 3 feela (0,8%). metsoako e meng boima ba bona ke lik’hilograma tse 41 (karolo ea 10,3 lekholong).
