Lub hauv paus ntsiab lus ntawm lithium ion roj teeb Lub roj teeb lithium ion yog tsim los ntawm ib qho zoo electrode, anode, diaphragm, thiab electrolyte. Qhov zoo thiab qhov tsis zoo electrode txheej yog nruj nreem dov ua ke, thiab txheej txheej thiab txheej txheej yog sib cais los ntawm cov insulator, thiab qhov zoo thiab qhov tsis zoo yog immersed nyob rau hauv electrolyte. Cov roj teeb cylindrical thiab cov roj teeb square tau siv los ua lithium ion roj teeb qauv roj teeb uas muaj ob hom lithium-insertic sib txawv, raws li.

Cov khoom zoo electrode yog nruj nreem hloov hlau oxide, hlau oxide, hlau sulfide, thiab lwm yam. kev lag luam Cov khoom siv hluav taws xob zoo feem ntau siv hauv cov roj teeb lithium-ion yog cov khoom siv anode feem ntau siv rau kev hloov hlau oxides. Cov khoom siv anode yog nruj nreem inorganic non-metallic cov ntaub ntawv, hlau-non-metallic composites, hlau oxides, thiab lwm yam.

lithium hlau phosphate cov khoom zoo thiab tsis zoo Cov khoom siv hluav taws xob electrode yog tsim los ntawm cov khoom siv hluav taws xob txiav txim siab qhov hluav taws xob thiab lub peev xwm electrolyte ntawm lub roj teeb raws li ib feem nruj ntawm lithium ion roj teeb, thiab plays lub siab xav rau tam sim no kis tau tus mob thaum lub sij hawm roj teeb thiab tawm. Txhawm rau tiv thaiv cov khoom siv hluav taws xob zoo thiab tsis zoo rau hauv cov khoom siv hluav taws xob hauv cov tshuaj electrolytic, cov khoom siv hluav taws xob zoo thiab tsis zoo raug cais tawm ntawm cov khoom siv hluav taws xob zoo thiab tsis zoo uas yog raus hauv electrolyte. Lub LI yog muab los ntawm qhov zoo electrode, thiab qhov tsis zoo electrode yog embedded rau hauv qhov tsis zoo electrode, qhov zoo electrode yog nyob rau hauv ib tug lithium lub xeev, cov nyiaj them nqi ntawm cov electrons yog muab los ntawm lub sab nraud Circuit Court los xyuas kom meej qhov sib npaug ntawm tus nqi.

Cov paug tawm yog cuam tshuam nrog cov paug tawm, thiab Li raug tshem tawm los ntawm qhov tsis zoo electrode thiab yog embedded rau hauv cov khoom siv cathode los ntawm electrolyte. Nyob rau hauv ib txwm them thiab tso tawm cov xwm txheej, lithium ions tau kos thiab tshem tawm ntawm cov txheej txheem carbon thiab cov txheej txheem txheej, uas feem ntau tsuas yog ua rau kev hloov pauv ntawm qhov sib txawv ntawm cov khoom txheej yam tsis ua rau lawv cov qauv siv lead ua. Thaum lub sij hawm tus nqi thiab tso tawm, cov qauv tshuaj ntawm cov khoom siv electrode tsis zoo yog qhov hloov pauv.

Qhov sib npaug ntawm cov tshuaj tiv thaiv ion yog qhov tsis tuaj yeem ntxiv kev ntsuas kev ruaj ntseg hauv lub roj teeb, vim nws tab tom nrhiav kom muaj peev xwm ua kom lub roj teeb lub neej. Los ntawm 1991 lithium-ion roj teeb kev lag luam mus rau qhov kev sib tw no, lub zog muaj peev xwm ntawm lithium-ion roj teeb ntxiv cov txheej txheem ntawm plaub lossis tsib zaug lithium-ion roj teeb tawg. Yog li peb nkag siab tias nws ua haujlwm li cas, yog li peb tuaj yeem nkag siab tias qhov qub tshwm sim lithium ion roj teeb tawg.

Them thiab tso tawm ntawm lithium ceg siv lead ua kev loj hlob roj teeb yog kev xa rov qab ntawm lithium ions. Thaum them nyiaj, lithium ions raug txo kom cov hlau lithium embedded hauv qhov tsis zoo electrode. Feem ntau, lithium tuaj yeem muab tso rau hauv cov qauv interlayer, uas tuaj yeem loj hlob nyob rau hauv qhov chaw ntawm cov electrode vim qhov tsis paub meej ntawm kev loj hlob, thiab cov txheej txheem loj hlob muaj cov qauv stabbed tib yam li cov ceg, uas tuaj yeem ua rau lub diaphragm ntawm lub roj teeb puas, ua rau luv luv hauv lub roj teeb.

Thiab roj teeb tawg. Yog tias lub roj teeb muaj qhov tsis zoo, cov hlau txuas txuas qhov zoo tsis zoo electrode los ntawm lub roj teeb insulating txheej, hloov cov kev taw qhia ntawm tam sim no, ua rau cov khoom siv sab hauv degrade, kom cov tshuaj tiv thaiv tsis zoo, tso cua sov ntau dua, ignit lub roj teeb pob roj teeb Charger peb lub roj teeb tam sim no muaj kev tiv thaiv, tawm tswv yim roj teeb voltage, nrog kev ceeb toom tshaj tawm, uas yuav ua rau overcharge, roj teeb tiv thaiv kab mob los yog kev puas tsuaj. Cov khoom siv cathode txuas ntxiv raug tshem tawm thiab kos rau hauv cov khoom tsis zoo electrode. Yog hais tias qhov siab tshaj plaws lithium embedded nyob rau hauv cov pa roj carbon tsis zoo electrode tau mus txog, cov lithium tshaj yuav tso rau ntawm cov khoom tsis zoo electrode nyob rau hauv daim ntawv ntawm lithium hlau, zoo heev txo cov stability ntawm lub roj teeb.

Txawm tias qhov tawg yog cuam tshuam nrog lub roj teeb lithium-ion, tsis yog tsuas yog lub roj teeb muaj peev xwm txhim kho, tab sis kev nyab xeeb kev ua haujlwm tsis tuaj yeem tsis quav ntsej. Niaj hnub no, qee lub tuam txhab roj teeb muaj cov qauv kev nyab xeeb siab, txawm tias yuav ntes cov roj teeb. Peb nkag siab tias thaum tus ntsia thawv nkag mus rau hauv lub roj teeb, nws yuav txuas ncaj qha mus rau qhov zoo tsis zoo, uas yuav ua rau lub cev luv luv.

Cov gel electrolyte thiab polymer electrolyte kuj tseem nyob rau hauv kev tshawb nrhiav ntxiv, tshwj xeeb tshaj yog kev txhim kho ntawm polymer electrolyte, tsis muaj kua organic electrolyte volatilization nyob rau hauv lub roj teeb, uas zoo heev txhim kho kev nyab xeeb ntawm lub roj teeb.
