1. Vertical kev koom ua ke ntawm kev lag luam saw kom ua tiav cov nqi txo thiab kev ua haujlwm zoo
Nyob rau hauv tus nqi ntawm cov ntaub ntawv tsis zoo electrode, tus nqi ntawm raw cov ntaub ntawv thiab graphitization processing links account rau ntau tshaj 85%, uas yog ob qho tseem ceeb txuas ntawm cov khoom tsis zoo cov nqi tswj.Nyob rau theem pib ntawm txoj kev loj hlob ntawm cov khoom siv tsis zoo electrode kev lag luam saw, kev sib txuas ntau lawm xws li graphitization thiab carbonization feem ntau vam khom cov chaw tsim khoom lag luam rau kev ua haujlwm vim muaj peev txheej loj thiab muaj kev cuam tshuam siab;Cov ntaub ntawv nyoos xws li rab koob coke thiab ntuj graphite ore yog yuav los ntawm cov khoom siv sib xws.
Niaj hnub no, nrog kev sib tw ntawm kev sib tw thoob ntiaj teb, ntau thiab ntau cov khoom lag luam tsis zoo tswj cov kev sib txuas tseem ceeb thiab cov ntaub ntawv tseem ceeb los ntawm kev sib koom ua ke ntsug ntawm cov saw hlau kom ua tiav cov nqi txo thiab kev ua haujlwm zoo.Cov tuam txhab ua lag luam xws li Betrie, Shanshan Shares, thiab Putailai tau paub txog graphitization tus kheej muab los ntawm cov khoom lag luam sab nraud thiab kev tsim kho ntawm cov phiaj xwm kev sib koom ua ke, thaum graphitization ua lag luam kuj tau nkag mus rau qhov tsis zoo electrode khoom tsim khoom.Tsis tas li ntawd, kuj tseem muaj cov tuam txhab ua lag luam los ntawm kev tau txais cov cai mining, kev koom nrog kev ncaj ncees thiab lwm txoj hauv kev kom ua tiav cov khoom siv tus kheej ntawm rab koob coke raw khoom.Qhov kev sib xyaw ua ke tau dhau los ua ib feem tseem ceeb ntawm kev sib tw tseem ceeb ntawm cov khoom lag luam tsis zoo electrode.
2. High kev lag luam teeb meem thiab ceev ceev hauv kev lag luam concentration
Peev, thev naus laus zis thiab cov neeg siv khoom tsim ntau yam kev lag luam teeb meem, thiab txoj hauj lwm ntawm cov lag luam tsis zoo tseem muaj zog ntxiv.Ua ntej, cov peev txheej tsis zoo, cov cuab yeej siv tsis zoo, cov khoom siv tshiab tshawb fawb thiab kev tsim kho, kev lag luam nplai, kev lag luam kev lag luam sab saud thiab qis qis, thiab lwm yam, yuav tsum muaj lub sijhawm ntev ntawm cov peev txheej loj, thiab cov txheej txheem tsis meej, muaj qee yam yuav tsum tau ua. rau lub zog nyiaj txiag ntawm kev lag luam, muaj peev txheej thaiv.Qhov thib ob yog cov txheej txheem kev teeb tsa, tom qab lub tuam txhab nkag mus, kev txhim kho txuas ntxiv ntawm cov txheej txheem tsim khoom yuav tsum muaj kev lag luam kom muaj kev sib sib zog nqus cov keeb kwm yav dhau los, thiab kev tshawb fawb tob txog kev xaiv cov khoom siv raw thiab cov txheej txheem cov ntsiab lus, thiab cov txheej txheem kev teeb tsa kuj tseem muaj. siab.Thib peb, cov neeg siv khoom tsis sib haum, vim muaj ntau yam xws li kev tsim khoom thiab kev ua tau zoo, cov neeg siv khoom zoo hauv qab feem ntau tsim kev sib raug zoo nrog cov tuam txhab cov khoom siv lub taub hau, thiab vim tias cov neeg siv khoom ceev faj heev hauv kev xaiv cov khoom, cov ntaub ntawv yuav tsis raug hloov tom qab nkag mus. cov khoom siv, cov neeg siv khoom stickiness siab, yog li kev lag luam cov neeg siv khoom teeb meem siab.
Kev lag luam teeb meem yog siab, lub zog hais lus ntawm cov tuam txhab ua lag luam yog superimposed, thiab cov concentration ntawm cov khoom siv electrode tsis zoo hauv kev lag luam yog siab.Raws li cov ntaub ntawv high-tech lithium roj teeb, Tuam Tshoj cov khoom siv hluav taws xob tsis zoo hauv kev lag luam concentration CR6 tau nce los ntawm 50% hauv 2020 txog 80% hauv 2021, thiab kev lag luam concentration nce sai.
3. Graphite anode cov ntaub ntawv tseem yog cov khoom siv tseem ceeb, thiab cov khoom siv silicon muaj peev xwm zoo rau kev siv yav tom ntej
Cov txiaj ntsig zoo ntawm graphite anode cov ntaub ntawv yog qhov pom tseeb, thiab nws yog lub ntsiab ntawm lithium roj teeb anode cov ntaub ntawv rau lub sijhawm ntev.Raws li cov ntaub ntawv high-tech lithium, xyoo 2022, kev lag luam sib koom ntawm graphite anode cov ntaub ntawv yog kwv yees li 98%, tshwj xeeb tshaj yog cov khoom siv dag zog graphite anode, thiab nws cov khoom lag luam tau nce txog li 80%.
Piv nrog rau cov ntaub ntawv graphite, silicon-raws li tsis zoo electrode cov ntaub ntawv muaj peev xwm ntau dua theoretical thiab yog ib yam tshiab ntawm cov ntaub ntawv tsis zoo electrode uas muaj peev xwm siv tau zoo.Txawm li cas los xij, vim muaj kev loj hlob zoo thiab teeb meem txuam nrog lwm cov ntaub ntawv ntawm cov khoom tsis zoo, cov khoom siv silicon tseem tsis tau siv rau ntawm qhov loj.Nrog rau kev txhim kho txuas ntxiv ntawm kev ua kom muaj zog ntawm cov tsheb tshiab, cov ntaub ntawv lithium roj teeb anode kuj tseem txhim kho nyob rau hauv cov kev taw qhia ntawm lub peev xwm tshwj xeeb, thiab kev tshawb fawb thiab kev tsim kho thiab kev taw qhia ntawm silicon-raws li anode cov ntaub ntawv yuav tsum ceev.
