Nyob rau hauv kev loj hlob sai ntawm cov tsheb fais fab tshiab, qhov kev khiav tau sai thiab kev nyab xeeb yog qhov tseem ceeb tshaj plaws hauv kev sib tw. Txhawm rau daws qhov kev txhawj xeeb txog qhov kev khiav tau sai, kev ua kom lub cev sib dua tau dhau los ua ib qho thev naus laus zis tseem ceeb hauv kev lag luam. Nyob rau hauv qhov xwm txheej no, cov vaj huam sib luag honeycomb txhuas, uas yog cov khoom siv sib xyaw ua ke zoo, tab tom ua lawv txoj hauv kev los ntawm kev lag luam aerospace mus rau cov tsheb fais fab txhua hnub, ua qhov tseem ceeb zais cia rau kev tsim cov tsheb tiam tom ntej.
Cov vaj huam sib luag ua los ntawm txhuas honeycomb yog lub npe nrov rau lawv cov qauv "sandwich" tshwj xeeb, uas muaj lub plawv honeycomb txhuas hexagonal nyob hauv nruab nrab, npog ob sab nrog cov ntawv txhuas nyias nyias. Tus qauv tsim no ua tiav qhov sib piv ntawm lub zog thiab qhov hnyav siab heev (lub zog tshwj xeeb), muab kev tiv thaiv zoo heev rau kev sib zog thiab kev khoov thaum tseem sib dua heev, tej zaum yuav txo qhov hnyav ntau dua 50% piv rau cov qauv hlau ib txwm muaj. Lawv daim ntawv thov hauv cov roj teeb qis dua, qhov rooj, thiab pem teb tuaj yeem txo qhov hnyav ntawm lub tsheb, ua rau muaj kev nce qib zoo dua.
Ntxiv rau qhov txo qhov hnyav, kev nyab xeeb yog lwm qhov zoo tseem ceeb. Cov vaj huam sib luag honeycomb txhuas muaj kev tiv thaiv kev cuam tshuam zoo heev thiab cov khoom nqus hluav taws xob, tiv thaiv cov roj teeb hauv kev sib tsoo. Qhov tseem ceeb tshaj, nws qhov kev tiv thaiv hluav taws kub zoo heev thiab kev tiv thaiv kub siab (nws tuaj yeem tswj tau qhov ruaj khov ntawm cov qauv rau lub sijhawm ntev ntawm qhov kub ntawm 800 ° C) muab qhov tseem ceeb "firewall" rau lub cev roj teeb, ua rau lub tsheb muaj kev nyab xeeb zoo dua.
Nrog rau cov tuam txhab roj teeb ua lag luam xws li Contemporary Amperex Technology (CATL) ua tus thawj coj hauv kev siv nws, cov vaj huam sib luag honeycomb txhuas tau hloov pauv ntawm cov thev naus laus zis tshiab mus rau kev siv loj. Lawv tsis yog tsuas yog cov khoom siv zoo tshaj plaws rau kev ua kom lub cev sib dua tab sis kuj yog lub zog tseem ceeb hauv kev tiv thaiv kev nyab xeeb ntawm roj teeb thiab tsav tsheb lub zog tshiab mus rau qib siab dua ntawm kev txhim kho zoo.
