Lub lim tiam tshiab thiab lub roj teeb tshiab. Tam sim no electrodes ua los ntawm nanoparticles ntawm manganese thiab titanium oxides es tsis txhob cobalt thiab npib tsib xee.
Txheem
Cov kws tshawb fawb los ntawm University of Yokohama (Nyiv) tau luam tawm cov ntaub ntawv tshawb fawb ntawm cov hlwb uas cobalt (Co) thiab npib tsib xee (Ni) tau hloov los ntawm oxides ntawm titanium (Ti) thiab manganese (Mn), hauv av mus rau theem uas qhov loj me me. nyob rau hauv pua. nanometers. Cov hlwb yuav tsum pheej yig dua los tsim thiab muaj peev xwm piv rau lossis zoo dua li niaj hnub lithium-ion hlwb.
Qhov tsis muaj cobalt thiab nickel hauv lithium-ion roj teeb txhais tau tias tus nqi qis dua.

Hom lithium-ion hlwb yog tsim los siv ntau yam technologies thiab sib txawv ntawm cov ntsiab lus thiab cov tshuaj sib txuas siv hauv cathode. Hom tseem ceeb tshaj plaws yog:
- NCM or NMC - i.e. raws li nickel-cobalt-manganese cathode; lawv tau siv los ntawm cov tuam txhab hluav taws xob feem ntau,
- NKA - i.e. raws li nickel-cobalt-aluminium cathode; Tesla siv lawv
- LFP - raws li hlau phosphates; BYD siv lawv, qee lub npe Suav siv lawv hauv tsheb npav,
- LCO - raws li cobalt oxides; peb tsis paub lub tuam txhab tsheb uas yuav siv lawv, tab sis lawv tshwm sim hauv electronics,
- LMOs - i.e. raws li manganese oxides.
Kev sib cais yog yooj yim los ntawm kev muaj cov kev sib txuas uas txuas cov thev naus laus zis (piv txwv li, NCMA). Tsis tas li ntawd, lub cathode tsis yog txhua yam, tseem muaj electrolyte thiab anode.
> Samsung SDI nrog lithium-ion roj teeb: hnub no graphite, silicon sai sai, sai lithium hlau hlwb thiab ntau yam ntawm 360-420 km hauv BMW i3
Lub hom phiaj tseem ceeb ntawm kev tshawb fawb feem ntau ntawm cov lithium-ion hlwb yog txhawm rau ua kom lawv lub peev xwm (lub zog ceev), kev ua haujlwm nyab xeeb thiab kev them nqi nrawm thaum txuas ntxiv lawv lub neej kev pabcuam. thaum txo cov nqi... Kev txuag nqi tseem ceeb yog los ntawm kev tshem tawm cobalt thiab npib tsib xee, ob lub ntsiab lus kim tshaj plaws, los ntawm cov hlwb. Cobalt yog qhov teeb meem tshwj xeeb vim nws yog mined feem ntau hauv Africa, feem ntau siv cov menyuam yaus.
Cov tuam ntxhab tshaj plaws niaj hnub no nyob hauv ib tus lej (Tesla: 3 feem pua) lossis tsawg dua 10 feem pua.
Dab tsi tau ua tiav hauv Nyij Pooj?
Cov kws tshawb fawb Yokohama hais tias Lawv tau tswj kom hloov tag nrho cobalt thiab npib tsib xee nrog titanium thiab manganese. Txhawm rau ua kom lub peev xwm ntawm cov electrodes, lawv av qee cov oxides (tej zaum manganese thiab titanium) kom lawv cov khoom muaj ntau pua nanometers loj. Kev sib tsoo yog ib txoj kev siv feem ntau vim hais tias, muab qhov ntim ntawm cov khoom, nws ua rau thaj tsam ntawm cov khoom siv.
Tsis tas li ntawd, qhov loj ntawm thaj chaw saum npoo, ntau qhov nooks thiab tawg hauv cov qauv, qhov muaj peev xwm electrode ntau dua.
Qhov kev tso tawm qhia tau hais tias cov kws tshawb fawb tau ua tiav hauv kev tsim cov qauv ntawm cov hlwb nrog cov khoom muaj txiaj ntsig thiab tam sim no tab tom nrhiav rau cov koom tes hauv cov tuam txhab tsim khoom. Cov kauj ruam tom ntej yuav yog qhov kev sim loj ntawm lawv qhov kev ua siab ntev, ua raws li kev sim ntawm kev tsim khoom loj. Yog hais tias lawv cov parameter tau cog lus, lawv yuav mus txog lub tsheb fais fab tsis pub dhau 2025..
Qhov no yuav txaus siab rau koj:
