Graphite Anode roj teeb

(Graphite Anode roj teeb)

Lub graphite anode roj teeb tau dominated LIBs txij li thaum lawv yug los 30 xyoo dhau los, tau txais txiaj ntsig los ntawm nws cov nyiaj tshuav zoo heev, muaj, lub zog thiab lub zog ntom ntom. Txawm tias mob siab rau kev tshawb fawb txog kev xaiv nrog kev ua tau zoo dua, cov khoom tsis sib xws ntawm graphite li lithium-ion intercalation party tau ua rau nws yog ib feem tseem ceeb ntawm LIBs lag luam.

Kev ua tau zoo ntawm graphite hauv anode yog ua tiav los ntawm nws qhov ntev-txheej txheej txheej txheej thiab electrochemical intercalation / deintercalation ntawm lithium ions.. Cov txheej txheem no ua rau siab theoretical reversible muaj peev xwm (372.0 mAh g-1) thiab lub neej voj voog zoo heev. Feem ntau, Lub graphite anode muaj kev ruaj ntseg zoo vim nws qhov loj ntawm thaj chaw thiab kev ua haujlwm siab.

Txawm li cas los, kev ua tau zoo ntawm graphite hauv LIBs tseem muaj qee qhov kev txhim kho. Ib qho tseem ceeb yog nws qhov qis thawj lub voj voog irreversible peev xwm poob, uas txwv cov peev txheej siab ntawm LIBs lag luam. Kev tshawb fawb tam sim no yog tsom rau kev txhim kho cov khoom siv anode lub morphology kom txo tau lub peev xwm poob.

Qhov no suav nrog kev hloov kho cov graphite particle morphology kom nce qhov chaw saum npoo thiab ua kom luv txoj hauv kev ntawm ionic diffusion. Lwm qhov kev tshawb fawb yog tsom rau kev ntxiv cov khoom siv hluav taws xob rau cov khoom siv anode, uas tuaj yeem txhim kho nws qhov kev ua tau zoo ntawm electrochemical tag nrho.

Ntxiv mus, Kev rov ua dua tshiab ntawm kev siv GA yuav tsum tau txais kev saib xyuas tas li rau kev txuag cov peev txheej thiab kev tiv thaiv kev ua qias tuaj. Nws kuj tseem tsim nyog los tsim txoj hauv kev los txhim kho cov khoom siv anode reutilization thiab nce nws cov kev ua tau zoo. Qhov no yuav tsis tsuas yog txo qhov kev cia siab ntawm GA txawv teb chaws tab sis kuj txuag cov nqi thiab kev ua qias tuaj ib puag ncig.
