Dab tsi yog qhov txawv ntawm All-Solid-State Lithium Battery Thiab Solid State Lithium Battery?

Cov roj teeb khoom tsis yog tag nrho cov khoom siv electrolyte, qee qhov yog kua (sib tov ntawm cov kua thiab cov khoom nyob ntawm qhov sib xyaw).

All-solid-state lithium roj teeb yog lithium roj teeb uas muaj zog tab sis tsis muaj cov kua hauv lub xeev electrode thiab cov khoom siv electrolyte nyob rau hauv lub sijhawm ua haujlwm kub, yog li nws lub npe tag nrho yog tag nrho cov khoom electrolyte lithium roj teeb.

Lub roj teeb lithium ion tiag tiag muaj cov khoom siv electrolyte, tab sis tseem muaj cov kua electrolyte me ntsis. Semi-solid state electrolyte muaj xws li ib nrab ntawm cov khoom electrolyte, ib nrab ntawm cov kua electrolyte, los yog ib nrab ntawm cov roj teeb yog lub xeev, ib nrab ntawm nws yog kua. Tseem muaj cov roj teeb lithium ion uas muaj cov khoom tseem ceeb hauv lub xeev thiab cov kua dej me me.

Raws li cov khoom siv-state lithium ion roj teeb nyob hauv tsev thiab txawv teb chaws, nws yog nrov tas li. Amelikas, Europe, Nyiv, Kauslim Teb thiab Tuam Tshoj tau nqis peev rau nws nrog ntau lub hom phiaj. Piv txwv li, Asmeskas nqis peev feem ntau ntawm cov tuam txhab me thiab kev pib ua lag luam. Muaj ob lub lag luam kev noj qab haus huv hauv Asmeskas, ib qho yog S-akit3. Txawm hais tias nws tseem nyob rau theem pib, kev tsav tsheb mus txog 500 km.

Amelikas tsom mus rau kev cuam tshuam cov thev naus laus zis hauv cov tuam txhab me thiab cov lag luam pib, thaum Nyiv nyiam tshawb fawb cov roj teeb lithium-ion roj teeb. Lub tuam txhab nto moo tshaj plaws hauv Nyij Pooj yog Toyota, uas yuav paub txog kev lag luam hauv xyoo 2022. Yam dab tsi Toyota tsim tsis yog tag nrho cov khoom siv-lub xeev lithium ion roj teeb, tab sis cov roj teeb-lub xeev lithium ion.

Lub roj teeb lub xeev tsim los ntawm Toyota muaj graphitic, sulphide electrolytes ua cathode cov ntaub ntawv thiab high voltage anode. Lub peev xwm ntawm ib lub roj teeb yog 15 Ah, thiab qhov hluav taws xob yog kaum ob volts. Nws tuaj yeem ua tiav kev lag luam hauv 2022.

Yog li Nyiv tsis mob siab rau kev cuam tshuam kev siv tshuab, tab sis siv lub qub anode thiab cathode ntawm lithium ion roj teeb. Kauslim zoo ib yam li Nyiv, muaj graphite cathode tab sis tsis yog hlau lithium. Qhov tseeb, Suav teb zoo li ntawd. Vim tias peb twb muaj cov kab ntau lawm ntawm lithium ion roj teeb, tsis tas yuav rov pib dua ua ke.
