Kufufuza "Woyang'anira Wosaoneka" wa Mabatire a Lithium: Kutchuka kwa Chidziwitso Cholekanitsa ndi Mayankho Oyesera Molondola a Dacheng​

Mu dziko la mabatire a lithiamu omwe ali ndi microscopic microscopic, pali "woteteza wosaoneka" wofunikira - wolekanitsa, yemwenso amadziwika kuti nembanemba ya batri. Imagwira ntchito ngati gawo lalikulu la mabatire a lithiamu ndi zida zina zamagetsi. Opangidwa makamaka ndi polyolefin (polyethylene PE, polypropylene PP), olekanitsa ena apamwamba amagwiritsanso ntchito zokutira za ceramic (monga alumina) kapena zinthu zophatikizika kuti ziwonjezere kukana kutentha, zomwe zimapangitsa kuti zikhale zinthu zamafilimu okhala ndi ma pore. Kupezeka kwake kumagwira ntchito ngati "firewall" yolimba, yomwe imalekanitsa ma electrode abwino ndi oipa a batri ya lithiamu kuti apewe ma short circuits, pomwe nthawi yomweyo imagwira ntchito ngati "msewu waukulu wa ion," zomwe zimathandiza kuti ma ion aziyenda momasuka ndikuwonetsetsa kuti batri ikugwira ntchito bwino.

Kuchuluka kwa ma gram ndi makulidwe a cholekanitsa, zomwe zikuwoneka ngati zinthu wamba, zimabisa "zinsinsi" zazikulu. Kuchuluka kwa ma gram (kuchuluka kwa ma gram) kwa zinthu zolekanitsa batire ya lithiamu sikuti kumangowonetsa mwachindunji kuchuluka kwa ma membrane omwe ali ndi makulidwe ofanana ndi zofunikira za zinthu zopangira komanso kumagwirizana kwambiri ndi kuchuluka kwa zinthu zopangira zolekanitsa ndi makulidwe ake. Kuchuluka kwa ma gram kumakhudza mwachindunji kukana kwamkati, kuthekera kwa liwiro, magwiridwe antchito a cycle, ndi chitetezo cha mabatire a lithiamu.

Kukhuthala kwa cholekanitsa ndikofunikira kwambiri pa magwiridwe antchito ndi chitetezo cha batri. Kufanana kwa makulidwe ndi muyeso wokhwima wowongolera khalidwe panthawi yopanga, ndi kusinthasintha komwe kumafunika kuti kukhale motsatira miyezo yamakampani ndi kulolerana kwa kusonkhana kwa batri. Cholekanitsa chocheperako chimachepetsa kukana kwa ma ayoni a lithiamu osungunuka panthawi yoyenda, zomwe zimapangitsa kuti ma ionic conductivity ndi kuchepetsa impedance zitheke. Komabe, kuonda kwambiri kumafooketsa kusunga madzi ndi kutchinjiriza zamagetsi, zomwe zimakhudza kwambiri magwiridwe antchito a batri.

Pazifukwa izi, kuyesa makulidwe ndi kuchuluka kwa area kwa separator kwakhala njira zofunika kwambiri zowongolera khalidwe popanga batire ya lithiamu, zomwe zimatsimikizira mwachindunji momwe batire imagwirira ntchito, chitetezo, komanso kusinthasintha. Kuchuluka kwa aareal kumalepheretsa mayendedwe a lithiamu-ion, kuchepetsa mphamvu ya liwiro; kuchuluka kwa aareal kochepa kumawononga mphamvu ya makina, kuopseza kuphulika ndi ngozi zachitetezo. Olekanitsa opyapyala kwambiri amaika pachiwopsezo kulowa kwa ma electrode, zomwe zimayambitsa ma circuits amkati; olekanitsa onenepa kwambiri amawonjezera kukana kwamkati, kuchepetsa kuchuluka kwa mphamvu komanso kugwira ntchito bwino kwa chaji.

Pofuna kuthana ndi mavutowa, Dacheng Precision yayambitsa njira yake yoyezera kuchuluka kwa ma radiation (makulidwe) ya X-ray!

                 #Chiyeso choyezera kuchuluka kwa malo (kukhuthala) kwa X-ray

Chipangizochi ndi choyenera kuyesa zipangizo zosiyanasiyana, kuphatikizapo zoumba ndi PVDF, ndi kulondola kobwerezabwereza kwa muyeso wa mtengo weniweni × 0.1% kapena ±0.1g/m²​​, ndipo chapeza satifiketi yochotsera ma radiation kuti chigwiritsidwe ntchito bwino. Pulogalamu yake ili ndi ma heatmaps enieni, ma calibration okhazikika, malipoti a khalidwe la roll, MSA (Measurement System Analysis) imodzi yokha, ndi ntchito zina zapadera, zomwe zimathandiza kuthandizira muyeso wolondola kwambiri.

Poganizira zamtsogolo, Dacheng Precision idzakhazikika mu kafukufuku ndi chitukuko, ikupita patsogolo mosalekeza m'malire aukadaulo wakuya ndikuphatikizira zatsopano muzinthu zonse ndi ntchito. Pogwiritsa ntchito ukadaulo wamakono, tidzafufuza njira zoyezera zanzeru komanso zolondola, ndikupanga njira zogwirira ntchito zaukadaulo zodalirika komanso zogwira mtima kwa makasitomala athu. Ndi luso lopanga zinthu zapamwamba komanso mphamvu zoyendetsera zatsopano, tadzipereka kupititsa patsogolo makampani opanga mabatire a lithiamu kupita ku nthawi yatsopano ya chitukuko chapamwamba!
