Hauv lub neej niaj hnub no, kev tsis txaus ntawm lub zog, kev ua qias tuaj ib puag ncig thiab lwm yam teeb meem tau tsim teeb meem tseem ceeb rau noob neej.Ntau lub tuam txhab roj teeb tau nquag tshawb nrhiav thiab tsim ntau hom roj teeb, tshwj xeeb tshaj yog lithium-ion fais fab lithium-ion roj teeb ua tus neeg sawv cev siab heev los daws qhov teeb meem no.Lub bottleneck nyob rau hauv daim ntawv thov thiab nce qib ntawm lithium-powered lithium-ion roj teeb yog hais tias ib lub roj teeb nyob rau hauv lub roj teeb pob ua tsis tau tejyam thaum lub sij hawm ua ke daim ntawv thov, uas ua rau ib tug poob nyob rau hauv tag nrho cov kev ua tau zoo ntawm lub roj teeb pob thiab lub roj teeb pob siv ntau tshaj li qhov txwv. .
Cordless Rauj Laum 20mmRaws li cov khoom siv ntawm lub roj teeb hu ua lithium ion roj teeb, uas tau muab faib ua thawj lithium ion roj teeb thiab lub roj teeb lithium ion thib ob.
Lub roj teeb uas tuaj yeem ntxig thiab de-intercalate lithium ions nrog cov ntaub ntawv carbon tuaj yeem hloov cov lithium ntshiab raws li qhov tsis zoo electrode, lithium compound tuaj yeem siv los ua cov electrode zoo, thiab cov electrolyte sib xyaw tuaj yeem siv los ua electrolyte.
Cov ntaub ntawv ntawm qhov zoo electrode ntawm lithium ion roj teeb feem ntau yog tsim los ntawm cov khoom siv hluav taws xob ntawm lithium, thaum cov electrode tsis zoo yog carbon nrog cov qauv tshwj xeeb molecular.Lub ntsiab tseem ceeb ntawm cov ntaub ntawv zoo yog LiCoO2.Thaum them nyiaj, lub peev xwm hluav taws xob ntawm lub roj teeb sab qaum teb thiab sab qab teb ua rau cov khoom sib xyaw hauv qhov zoo electrode tso tawm lithium ions, thiab cov electrode tsis zoo yog embedded nyob rau hauv cov pa roj carbon nyob rau hauv ib txheej txheej.Thaum lub sij hawm tso tawm, lithium ions raug cais tawm ntawm cov pa roj carbon monoxide thiab rov ua dua nrog cov khoom siv tau zoo.Cov hluav taws xob tam sim no tshwm sim hauv kev txav ntawm lithium ions.
Txawm hais tias lub hauv paus ntsiab lus ntawm cov tshuaj tiv thaiv yog yooj yim heev, nyob rau hauv qhov tseeb industrial ntau lawm, muaj ntau yam tswv yim teeb meem los xav txog: cov ntaub ntawv ntawm qhov zoo electrode yuav tsum tau hais kom rov them cov dej num rau cov additives, thiab cov ntaub ntawv ntawm qhov tsis zoo electrode yuav tsum muaj ntau. lithium ions ntawm lub molecular qauv tsim theem;Nyob rau hauv cov electrolyte ntim ntawm qhov zoo electrode thiab qhov tsis zoo electrode, ntxiv rau kev ruaj ntseg, kuj muaj cov conductivity zoo heev los txo qhov tsis kam ntawm roj teeb.
Txawm hais tias lub roj teeb lithium-ion yuav luag tsis muaj kev cuam tshuam, nws lub peev xwm tseem yuav txo qis tom qab them rov qab, uas yog vim qhov hloov pauv ntawm cov ntaub ntawv zoo thiab tsis zoo nws tus kheej.Los ntawm qib molecular, kab noj hniav qauv ntawm lithium ions ntawm qhov zoo thiab tsis zoo electrodes yuav maj mam vau thiab thaiv.Los ntawm cov tshuaj lom neeg pom, nws yog cov ntaub ntawv kev ua haujlwm passivation ntawm qhov zoo electrode thiab qhov tsis zoo electrode, thiab lwm cov tebchaw uas ruaj khov hauv cov tshuaj tiv thaiv theem nrab tshwm sim.Kuj tseem muaj qee qhov kev mob ntawm lub cev, xws li maj mam tshem tawm cov ntaub ntawv zoo electrode, uas thaum kawg yuav txo cov lithium ions hauv lub roj teeb, tso cai rau nws txav mus los ywj pheej thaum them thiab tawm.
Overcharge thiab tso tawm tsim kev puas tsuaj mus tas li rau cov electrodes ntawm lithium-ion roj teeb.Los ntawm qib molecular, nws tuaj yeem nkag siab qhov tseeb tias anode carbon emissions yuav ua rau ntau tshaj tawm ntawm lithium ions thiab txo qis hauv txheej txheej, thiab overcharging yuav ua rau ntau dhau ntawm lithium ions tsis yooj yim ntsaws rau hauv cov qauv ntawm cathode carbon, thiab qee qhov. lithium ions tsis tuaj yeem tso tawm.Qhov no yog vim li cas cov roj teeb lithium-ion feem ntau yog nruab nrog kev them nqi thiab kev tswj xyuas hluav taws xob.
