Kev nce qib tshiab hauv kev tshawb fawb ntawm micro-lithium-ion roj teeb hauv Dalian Institute of Chemical Technology

Tsis ntev los no, pab pawg ntawm Wu Zhongshuai, tus kws tshawb fawb ntawm ob-seem cov ntaub ntawv thiab cov cuab yeej siv hluav taws xob tshawb fawb ntawm Dalian Institute of Chemical Physics, Suav Academy of Sciences, thiab pab pawg ntawm Bao Xinhe, kws tshaj lij ntawm Suav Academy ntawm Kev Tshawb Fawb, tau tsim ib qho kev sib xyaw ua ke tag nrho nrog ntau qhov kev coj ua huab hwm coj hloov pauv, zoo heev yooj thiab kub ruaj khov. Solid-state lithium-ion micro roj teeb. Cov txiaj ntsig kev tshawb fawb cuam tshuam tau luam tawm ntawm NanoEnergy.

Nrog rau txoj kev loj hlob sai ntawm kev hloov pauv tau yooj yim, cov khoom siv me me, thiab cov khoom siv hluav taws xob sib xyaw ua ke, nws yog qhov tsim nyog los tsim kom muaj kev ua tau zoo, lub teeb yuag, hnav, thiab cov qauv ua haujlwm ua ke nrog cov khoom siv hluav taws xob hloov pauv thiab lawv cov thev naus laus zis. Lithium-ion roj teeb yog tam sim no siv ntau tshaj plaws thiab nrov lub zog hauv zej zog, tab sis nws muaj teeb meem kev nyab xeeb xws li qhov loj me, ruaj khov, tsis yooj yim, electrolyte to thiab flammability, yog li nws nyuaj rau ua kom tau raws li qhov yuav tsum tau hloov pauv thiab me me. khoom siv hluav taws xob. xav tau.

Tsis ntev los no, pab pawg tshawb fawb tau ua tus thawj coj hauv kev tsim kho tag nrho-lub xeev cov phiaj xwm sib xyaw ua ke lithium-ion me me roj teeb. Lub lithium-ion micro roj teeb siv nano lithium titanate nanospheres raws li qhov tsis zoo electrode, lithium hlau phosphate microspheres ua cov electrode zoo, muaj cov khoom siv graphene zoo li cov khoom tsis yog xim hlau tam sim no, thiab ion gel li cov electrolyte. Nws muaj kev teeb tsa tus ntiv tes sib txuas thiab tsis tas yuav siv cov Diaphragm thiab cov khoom siv hlau tam sim no.

Cov tau txais lithium-ion micro roj teeb muaj qhov zoo ntawm ntau txoj kev hloov pauv huab cua, qhia lub zog ntim siab ntawm 125.5mWh / cm3, kev ua haujlwm zoo heev; ultra-ntev voj voog stability, yuav luag tsis muaj peev xwm degradation tom qab 3300 cycles; thiab zoo mechanical zog Flexible, lub electrode qauv yuav tsis puas thiab cov electrochemical kev ua tau zoo yuav tsis hloov ho nyob rau hauv rov khoov los yog twisting.

Nyob rau tib lub sijhawm, cov khoom siv hluav taws xob me me tuaj yeem ua haujlwm ruaj khov hauv qhov kub thiab txias ntawm 100 ° C thiab muaj lub voj voog ntev ntev (1000 cycles). Tsis tas li ntawd, lub roj teeb lithium-ion tuaj yeem paub txog kev sib koom ua ke ntawm tus kheej yam tsis muaj hlau txuas, thiab paub txog kev tswj hwm ntawm cov zis voltage thiab muaj peev xwm. Yog li ntawd, cov roj teeb lithium ion me me muaj peev xwm ua tau zoo hauv kev siv cov khoom siv hluav taws xob hloov tau yooj yim thiab me me.
