Graphite Anode Khoom Vs Silicon Anode Khoom

(Graphite Anode Khoom Vs Silicon Anode Khoom)

graphite anode cov ntaub ntawv tau dominated lub roj teeb kev lag luam txij li thaum nws pib, ua tsaug rau nws qhov sib npaug sib npaug ntawm tus nqi qis, kev muab khoom ntau, siab zog ceev thiab lub neej voj voog ntev. Qhov kev sib xyaw ua ke ntawm cov khoom no tau ua tus tsav tsheb tseem ceeb rau kev txhim kho cov roj teeb lithium-ion siab heev uas tau npaj los tsav lub neej yav tom ntej ntawm lub tsheb hluav taws xob thiab daim phiaj hluav taws xob cia..

Thaum them nyiaj, Li-ions ntws los ntawm cathode mus rau anode los ntawm ib qho electrolyte tsis uas cais ob lub electrodes.. Thaum tso tawm, tib cov txheej txheem yog thim rov qab thaum lub roj teeb tso tawm lub zog.

Cov khoom siv anode yuav tsum tswj cov ions thiab electrons zoo thaum them nqi / tawm, thaum tseem tiv thaiv nws saum npoo los ntawm kev tawg thiab o. Graphite muaj peev xwm ua tau zoo heev, tab sis nws kuj yuav tsum tau ua tshwj xeeb thiaj li yuav siv tau los ua ib qho anode.

Silicon yog suav tias yog lwm txoj hauv kev rau graphite ua cov khoom siv anode, tab sis nws raug kev txom nyem los ntawm ntau yam tsis zoo. Nws muaj ntau dua theoretical zog thiab volumetric ntom piv nrog graphite, tab sis nws kuj swells ntau tshaj graphite thaum lub sij hawm them nqi / tso tawm cycling, uas ua rau cell instability, muaj peev xwm degradation thiab txo lub voj voog lub neej thaum nws siv nyob rau hauv qhov loj proportions.

Raws li qhov tshwm sim, silicon anode developers tab tom sib tw kom ruaj ntseg patent tiv thaiv thiab kev lag luam tshwj xeeb. Ntxiv rau, muaj kev txhawj xeeb tias kev lag luam consolidation yuav tshwm sim raws li kev ua lag luam rau silicon anode cov ntaub ntawv matures.
