Lithium hlau yuav tsum dhau los ua cov khoom siv anode kawg ntawm tag nrho cov roj teeb Solid-state

Raws li cov lus ceeb toom, cov kws tshawb fawb los ntawm Tohoku University thiab Lub Koom Haum Tshawb Fawb Lub Zog Hluav Taws Xob Accelerator hauv Nyij Pooj tau tsim cov khoom sib xyaw hydride lithium superion tshiab.Cov kws tshawb fawb tau hais tias cov khoom siv tshiab no, uas tau paub los ntawm kev tsim qauv ntawm hydrogen pawg (composite anion) qauv, qhia tau tias muaj kev ruaj ntseg zoo heev rau lithium hlau, uas xav tias yuav dhau los ua cov khoom siv anode kawg ntawm tag nrho cov roj teeb hauv lub xeev, thiab txhawb nqa lub zog. tiam ntawm tag nrho cov Solid-state roj teeb nrog lub zog siab tshaj plaws kom deb li deb.

Tag nrho cov roj teeb Solid-state nrog lithium hlau anode yuav tsum daws cov teeb meem ntawm electrolyte to, flammability thiab tsawg zog ceev ntawm cov tsoos lithium ion roj teeb.Nws feem ntau ntseeg tias lithium hlau yog cov khoom siv anode zoo tshaj plaws rau tag nrho cov khoom siv hluav taws xob, vim tias nws muaj peev xwm theoretical siab tshaj plaws thiab muaj peev xwm qis tshaj ntawm cov ntaub ntawv anode paub.
Lithium ion conduction khoom electrolyte yog ib qho tseem ceeb ntawm tag nrho cov khoom siv roj teeb, tab sis qhov teeb meem yog tias feem ntau ntawm cov khoom siv hluav taws xob uas twb muaj lawm muaj tshuaj lom neeg / hluav taws xob tsis ruaj khov, uas yuav ua rau muaj kev cuam tshuam tsis tsim nyog ntawm qhov cuam tshuam, ua rau muaj kev cuam tshuam ntau ntxiv, thiab txo cov roj teeb ua haujlwm tau zoo thaum lub sijhawm them rov qab thiab tso tawm.

Cov kws tshawb fawb tau hais tias cov khoom sib xyaw hydrides tau txais kev saib xyuas thoob plaws hauv kev hais txog cov teeb meem ntsig txog lithium hlau anodes, vim tias lawv muaj cov tshuaj zoo heev thiab electrochemical stability ntawm lithium hlau anodes.Cov khoom tshiab electrolyte lawv tau txais tsis tau tsuas yog muaj ionic conductivity, tab sis kuj yog ruaj khov rau lithium hlau.Yog li ntawd, nws yog qhov kev ua txhaum tiag tiag rau tag nrho cov roj teeb lub xeev siv lithium hlau anode.

Cov kws tshawb fawb tau hais tias, "Qhov kev txhim kho no tsis tsuas yog pab peb nrhiav cov khoom siv hluav taws xob lithium ion raws li kev sib xyaw hydrides yav tom ntej, tab sis kuj tseem qhib cov kev hloov tshiab ntawm cov khoom siv electrolyte. cov khoom siv hluav taws xob siab ceev electrochemical.

Cov tsheb hluav taws xob cia siab tias muaj zog ceev thiab cov roj teeb muaj kev nyab xeeb kom ua tiav qhov kev txaus siab.Yog tias cov electrodes thiab electrolytes tsis tuaj yeem koom tes zoo ntawm cov teeb meem electrochemical stability, yuav muaj kev cuam tshuam ntawm txoj kev mus rau kev nrov ntawm cov tsheb hluav taws xob.Kev koom tes zoo ntawm lithium hlau thiab hydride tau qhib cov tswv yim tshiab.Lithium muaj peev xwm unlimited.Lub tsheb hluav taws xob nrog ntau ntawm ntau txhiab mais thiab smartphones nrog ib lub lis piam standby yuav tsis nyob deb.
