I-IBM idale amaseli amasha e-lithium-ion ngaphandle kwe-cobalt ne-nickel. Ilayisha kufika ku-80% ngemizuzu emi-5 ngaphezu kuka-0,8 kWh/l!
Amaseli amasha e-lithium-ion avela elebhu yocwaningo ye-IBM. Basebenzisa "izinto ezintathu ezintsha" futhi ibhethri elenziwe ngazo lingashaja kufika kumaphesenti angu-80 ngaphansi kwamaminithi angu-5. Abasebenzisi i-cobalt ebizayo noma i-nickel, enganciphisa intengo yezimoto zikagesi esikhathini esizayo.
Ama-elementi amasha avela ku-IBM: ashibhile, angcono, asebenza kahle kakhulu
vele Ngo-2016, abakhiqizi bamaseli namabhethri badle amaphesenti angama-51 okukhiqizwa kwe-cobalt emhlabeni.... Abanye ososayensi bebelindele ukwanda kwentshisekelo ezimotweni zikagesi kuzonyusa intengo yensimbi njengoba ukutholakala kwayo kulinganiselwe. Futhi lokhu naphezu kokuthi izinkampani eziningi zisebenzela ukuqeda lesi sici kumabhethri e-lithium-ion.
Izintengo ze-cobalt ezikhuphukayo zehlisa ukwehla kwentengo yezimoto zikagesi. Azohlala eseduze neleveli yamanje:
> Umbiko we-MIT: Izimoto zikagesi ngeke zehle intengo ngokushesha njengoba ucabanga. Kubiza kakhulu ngo-2030
okwamanje I-IBM cell cathodes ayinayo i-cobalt, i-nickel nezinsimbi ezisindayo.futhi izakhi ezisetshenziswa kuzo zingakhishwa emanzini olwandle (umthombo).
Ngekhwalithi izindleko zebhethri namuhla cishe 1/3 yezindleko zemoto kagesi., lapho izakhi ezakha amangqamuzana zishibhile, ishibhile intengo yokugcina yemoto kagesi iphansi.
> Ingakanani i-cobalt ebhethrini lemoto kagesi? [SIZOPHENDULA]
Ngaphezu kwalokho, bayisebenzisa high flash point liquid electrolytesokungaba okubalulekile uma kwenzeka izingozi. Ngaphezu kwalokho, ama-electrolyte anamuhla avutha kakhulu.
I-IBM ithi ihlole ibhethri kumaseli ayo alungiselelwe ukusekela amandla aphezulu. Uphumelele ukushaja kufika kumaphesenti angu-80 ngaphansi kwemizuzu emi-5... Lokhu kuyosho ukuma esiteshini sokushaja cishe isikhathi esifanayo nokufaka uphethiloli.
Umkhiqizi uthembisa ukuthi amaseli amasha azodala amabhethri asebenza kangcono kunamaseli e-lithium-ion amanje. Isibonelo, bazohlinzeka ngamandla angaphezu kuka-10 kW ilitha ngalinye lebhethri (10 kW / l) futhi sebevele bekwazi ukufinyelela ukuminyana kwamandla kagesi. ngaphezu kwe-0,8 kWh / l.
Ngokuqhathanisa, i-CATL yaqhosha kulo nyaka ukuthi isizukulwane sakamuva samaseli e-lithium-ion ane-cathode ecebile nge-nickel sesifinyelele. 0,7 kWh / l (kanye no-0,304 kWh / kg). Futhi i-TeraWatt ithi ikhiqize amaseli e-electrolyte aqinile ane-energy density engu-1,122 kWh / L (kanye no-0,432 kWh / kg):
> I-TeraWatt: Sinamabhethri aqinile e-electrolyte anamandla athile angu-0,432 kWh/kg. Itholakala kusukela ngo-2021
Ucwaningo lwamaseli lwenziwe ngabakwa-IBM ngokubambisana noDaimler, umnikazi womkhiqizo wakwaMercedes-Benz.
Isithombe sesethulo: phezulu kwesokunxele - ingaphakathi lelebhu yocwaningo, phezulu kwesokudla - amaseli ngesikhathi sokuhlolwa, ngezansi kwesokunxele - ikhemistri yeseli embozwe "amaphilisi" ayisicaba emshinini wokuhlola ibhethri (c) IBM
Inothi lomhleli www.elektrowoz.pl: 2016 Cobalt Consumption idatha evela ku-Cobalt Institute. Siwacaphuna ngoba esihlokweni esithi "Ukukhokhiswa Ngokugcwele" kwe-cobalt isimo sithi ihaba. Nakuba kuyiqiniso ukuthi i-cobalt isetshenziselwa ukucubungula uwoyela ongahluziwe (= ukukhiqizwa kukaphethiloli).
Lokhu kungase kube nentshisekelo kuwe:
