Lub zog tshuaj tau dhau los ua ib qho tseem ceeb ntawm lub zog cia rau tib neeg.Nyob rau hauv cov tshuaj siv roj teeb tam sim no,lub lithium roj teebyog suav tias yog qhov zoo tshaj plawslub zog ciantaus ntawv vim nws lub zog siab ceev, lub neej voj voog ntev, thiab tsis muaj kev nco.Tam sim no, cov roj teeb lithium-ion ib txwm siv cov organic kua electrolytes.Txawm hais tias cov kua electrolytes tuaj yeem muab cov ionic conductivity ntau dua thiab kev sib cuag zoo, lawv tsis tuaj yeem siv tau zoo hauv cov hlau lithium.Lawv muaj tsawg lithium ion tsiv teb tsaws thiab yooj yim rau xau.Cov teeb meem xws li volatile, flammable, thiab kev nyab xeeb tsis zoo cuam tshuam kev txhim kho ntxiv ntawm lithium roj teeb.Piv nrog cov kua electrolytes thiab inorganic khoom electrolytes, tag nrho cov khoom polymer electrolytes muaj qhov zoo ntawm kev nyab xeeb kev ua tau zoo, yoog raws, yooj yim ua rau hauv cov yeeb yaj kiab, thiab kev sib cuag zoo heev.Tib lub sijhawm, lawv tuaj yeem cuam tshuam qhov teeb meem ntawm lithium dendrites.Tam sim no, nws tau txais kev saib xyuas dav dav Txog tam sim no, tib neeg muaj kev xav tau siab dua thiab siab dua rau cov roj teeb lithium-ion hais txog kev nyab xeeb thiab lub zog ceev.Piv nrog rau lithium-ion roj teeb ntawm cov tshuaj ua kua organic, tag nrho cov khoom-lub xeev lithium roj teeb muaj qhov zoo ntawm qhov no.Raws li ib qho ntawm cov ntaub ntawv tseem ceeb ntawm tag nrho cov khoom-lub xeev lithium roj teeb, tag nrho cov khoom-state polymer electrolytes yog ib qho ntawm cov lus qhia tseem ceeb ntawm kev tshawb fawb tag nrho-lub xeev lithium roj teeb.Yuav kom ua tiav tag nrho cov khoom-state polymer electrolytes rau kev lag luam roj teeb lithium, nws yuav tsum ua tau raws li cov cai hauv qab no Ntau qhov yuav tsum tau muaj: chav tsev kub ion conductivity yog ze rau 10-4S / cm, lithium ion migration tooj yog ze rau 1, zoo heev mechanical zog, electrochemical qhov rais ze rau 5V, zoo tshuaj thermal stability, thiab environmentally friendly thiab yooj yim npaj txoj kev.
Pib los ntawm cov txheej txheem ntawm kev thauj mus los ntawm ion nyob rau hauv tag nrho cov khoom polymer electrolytes, cov kws tshawb fawb tau ua ntau txoj haujlwm hloov kho, suav nrog kev sib xyaw, copolymerization, kev loj hlob ntawm ib leeg-ion conductor polymer electrolytes, high- ntsev polymer electrolytes, ntxiv plasticizers, nqa tawm cross- txuas thiab tsim cov organic / inorganic composite system.Los ntawm cov kev tshawb fawb no, tag nrho cov kev ua tau zoo ntawm tag nrho cov khoom polymer electrolyte tau zoo heev, tab sis nws tuaj yeem pom tias tag nrho cov khoom polymer electrolyte uas tuaj yeem ua lag luam yav tom ntej yuav tsum tsis txhob tau txais los ntawm ib txoj kev hloov kho, tab sis ntau yam. kev hloov kho.Compound.Peb yuav tsum to taub qhov kev hloov kho mechanism kom meej meej, xaiv txoj kev hloov kho uas tsim nyog rau lub sijhawm tsis ncaj ncees lawm, thiab tsim cov khoom siv polymer electrolyte uas muaj peev xwm ua tau raws li qhov xav tau ntawm kev ua lag luam.
