Khoom- lub xeev cov roj teeb tuaj yeem raug cais raws li (semi-khoom-state, quasi-khoom-state, thiab tag nrho- khoom- lub xeev cov roj teeb). Txhawm rau ua kom nrov dua thiab nyiam mloog, lawv feem ntau tsuas yog hu ua cov roj teeb uas muaj zog - xeev.
Qhov sib txawv tseem ceeb ntawm semi-khoom- xeev, quasi-khoom- xeev, thiab tag nrho cov -khoom- lub xeev cov roj teeb nyob hauv lub cev ntawm electrolyte, ionic conductivity, teeb meem cuam tshuam, thiab kev loj hlob ntawm kev lag luam.
Daim ntawv qhia kev sib piv hauv qab no qhia meej meej cov ntsiab lus sib txawv ntawm peb:
1. Tag nrho -khoom- lub xeev roj teeb
Electrolyte lub xeev: 100% khoom, tsis muaj kua electrolyte. Feem ntau siv oxide, sulfide, lossis polymer khoom electrolytes.
Cov yam ntxwv tseem ceeb:
Kev nyab xeeb tshaj plaws:Ua tiav tshem tawm qhov kev pheej hmoo ntawm kev tawg, tawg, thiab tawg (tshwj xeeb tshaj yog muaj peev xwm loj tshaj plaws thaum siv lithium hlau anodes).
Lub zog muaj peev xwm siab tshaj plaws:Tau tshaj -voltage cathodes thiab lithium hlau anodes, theoretically ua tiav lub zog ceev tshaj 500 Wh / kg.
Cov teeb meem loj tshaj plaws interface:Khoom- cov khoom sib tiv tauj ua rau muaj kev cuam tshuam loj heev, cuam tshuam ion thauj khoom; ntsuas kev ua tau zoo thiab lub voj voog lub neej yog qhov nyuaj tshaj plaws.
Tus nqi nyuaj heev thiab txheej txheem:Cov txheej txheem tsim khoom yog qhov nyuaj (piv txwv li, kev ua cov nkig electrolytes, nyias zaj duab xis npaj), ua rau cov nqi siab heev thiab cov teeb meem tseem ceeb hauv kev tsim khoom loj.
Qhov xwm txheej tam sim no:Tam sim no nyob rau hauv R&D thiab pilot-scale ntau lawm theem. Nws yog dav lees paub tias yog "qhov kawg daws," tab sis ntsib txoj kev ntev tshaj plaws rau kev lag luam.
2. Quasi-Khoom-State Batteries
Electrolyte State:"Solid-like" lossis "gel-like," uas muaj cov lej (feem ntau<5%) of liquid electrolyte or plasticizer, with a very small amount of liquid wetting the gaps between solid electrolyte particles.
Cov yam ntxwv tseem ceeb:
Transitional Solution:Pom tau tias yog ib daim ntawv npaj rau tag nrho -khoom- lub xeev roj teeb. Nws txis "tag nrho solidity" rau kev ua tau zoo interfacial ntau dua.
Txhim kho Interface:Cov kab mob ntawm cov kua ua tau zoo txhim kho lub peev xwm thauj khoom ion ntawm cov khoom siv -cov khoom sib txuas thiab txo qhov cuam tshuam ntawm kev cuam tshuam.
Performance Balance Point:Nrhiav kom muaj qhov sib npaug ntawm kev nyab xeeb, lub zog ceev, thiab kev ua haujlwm ntawm electrochemical. Its energy density and safety are still significantly higher than liquid batteries, but slightly inferior to ideal all-solid-state batteries.
Tus neeg siv txheeb ze- Cov txheej txheem tsim khoom zoo:Ze rau cov kab ntau lawm ntau dua li tag nrho -khoom- lub xeev roj teeb.
Qhov xwm txheej tam sim no:Feem ntau sib tshooj nrog los yog siv sib hloov nrog lub tswv yim ntawm "semi-khoom-state," uas sawv cev rau cov kauj ruam tseem ceeb rau ntau lub tuam txhab txav los ntawm semi-khoom- xeev mus rau tag nrho -khoom- lub xeev roj teeb.
3. Semi-khoom- lub xeev roj teeb
Electrolyte State: Solid-liquid mixture, with both solid and liquid electrolytes coexisting, and a high liquid content (typically >5%, txawm mus txog 10-20%).
Cov yam ntxwv tseem ceeb:
Kev sib haum xeeb thiab kev txhim kho:Qhov tseem ceeb yog "kev txhim kho tseem ceeb" rau cov kua lithium -ion roj teeb uas twb muaj lawm, tsis yog kev kho dua tshiab. Feem ntau siv cov khoom siv electrolyte txheej los yog ua ke nrog cov khoom siv electrode.
Txhim kho kev nyab xeeb:Txo cov kua electrolyte cov ntsiab lus txo qhov kev pheej hmoo ntawm kev sib tsoo, tab sis tsis tshem tawm nws.
Tseem ceeb nce zog ceev:Ib feem tuaj yeem siv siab- muaj peev xwm zoo thiab tsis zoo electrode cov ntaub ntawv (xws li siab -nickel, silicon-} carbon), ua kom muaj zog ceev ntawm 300-400 Wh / kg.
Tau tshaj cov kab ntau lawm:Kev hloov kho me me rau cov txheej txheem ntau lawm, ua rau nws thawj txoj hauv kev kom ua tiav kev lag luam ntau lawm.
Leakage Risk Tseem:Qhov tseem ceeb tseem poob rau hauv qeb ntawm "cov roj teeb ua kua."
Qhov xwm txheej tam sim no:Twb tau nyob rau hauv huab hwm coj ntau lawm thiab tsheb installation theem.
