Cov kws tshawb fawb Suav tsim cov lithium{0}}ion roj teeb uas tiv thaiv kev sib tsoo thiab tawg
Recently, research published in the latest issue of the American Chemical Society's "Nano Letters" shows that Chinese scientists are expected to develop a lithium battery that is resistant to combustion and explosion. This lithium battery made of new materials is flexible, low-cost and more durable. Safety.
Pab neeg ntawm cov ntaub ntawv tus kws tshawb fawb Tao Xinyong ntawm Zhejiang University of Technology tau hloov cov kua electrolyte ib txwm muaj cov khoom electrolyte doped nrog magnesium borate. Qhov no yog cov organic-inorganic composite khoom. Cov inorganic magnesium borate tuaj yeem txhim kho ionic conductivity thiab mechanical zog ntawm electrolyte, thaum cov organic polymer tuaj yeem tswj tau yooj yim thiab tsis muaj kev ntxhov siab los ntawm qhov ntim hloov ntawm cov khoom siv electrode thaum them thiab tawm. Qhov ruaj khov electrode interface tau txais.
Tao Xinyong tau hais rau cov neeg sau xov xwm tias yog vim li cas cov khoom polymer cov khoom siv electrolytes tau nyuaj kom ua tiav qhov loj - daim ntawv thov ua ntej yog tias cov ionic conductivity ntawm cov electrolytes yog peb qhov kev txiav txim siab qis dua li cov kua electrolytes ntawm chav tsev kub. Hauv cov khoom tshiab -cov khoom siv hluav taws xob hauv xeev, magnesium borate tuaj yeem cuam tshuam nrog lithium ntsev anions kom nrawm nrawm ntawm lithium ions.
Tao Xinyong tau hais tias magnesium borate kuj yog ib qho uas tsis yog - ua paug, qis - toxicity nplaim retardant, uas yuav ua rau kom muaj kev ruaj ntseg ntawm fireproof carbon txheej. Ib txwm ua kua electrolytes feem ntau yog tsim los ntawm lithium hexafluorophosphate thiab flammable thiab tawg ethylene carbonate thiab dimethyl carbonate. Lub zog cia khoom xws li xov tooj ntawm tes thiab tsheb siv cov kua electrolytes muaj peev xwm ua rau muaj kev nyab xeeb ntawm kev sib tsoo thiab tawg.
Cov kws tshawb fawb tau hais tias cov khoom siv tshiab tau txhim kho ionic conductivity mus rau qhov loj, tab sis nws tseem tsis tau ua tiav kev ua haujlwm hauv chav sov thiab tsis tuaj yeem ua haujlwm tam sim ntawd, thiab xav tau kev tshawb fawb ntxiv.
