Kupita Patsogolo mu Ukadaulo Wokonzanso Mabatire a Lithium-Ion

Kafukufuku waposachedwa wofalitsidwa pa Julayi 29 mu magaziniyiZipangizo Zapamwamba Zogwira Ntchitoikufotokoza njira yachangu, yothandiza, komanso yosawononga chilengedwe yobwezeretsa lithiamu pogwiritsa ntchito kuwala kwa microwave komanso chosungunulira chomwe chimawonongeka mosavuta. Ofufuza ku Rice University ku United States apanga njira yatsopanoyi, yomwe imatha kubwezeretsa mpaka 50% ya lithiamu kuchokera ku ma cathode a lithiamu-ion omwe agwiritsidwa ntchito (LIB) m'masekondi 30 okha, zomwe zimachepetsa kwambiri vuto la ukadaulo wobwezeretsanso zinthu wa LIB.

Pakadali pano, kufunikira kwa lithiamu, chitsulo choyera ngati siliva, kukukwera kwambiri, kuposa kupezeka.

Njira zachikhalidwe zopezera lithiamu kuchokera ku mabatire omwe agwiritsidwa ntchito ndizowononga chilengedwe komanso sizigwira ntchito bwino. Mavuto akuluakulu ndi monga kuipitsidwa kwa lithiamu ndi kutayika kwake panthawi yobwezeretsa, kuphatikiza kugwiritsa ntchito mphamvu zambiri. Popeza lithiamu nthawi zambiri imachotsedwa pambuyo pa zitsulo zina, ofufuza afunafuna njira zomwe zimayang'ana kwambiri kubwezeretsa lithiamu.

Mu kafukufukuyu, ofufuzawa adagwiritsa ntchito chisakanizo cha choline chloride ndi ethylene glycol ngati chosungunulira chakuya (DES). Kale adapeza kuti panthawi yochotsa DES, ma lithiamu ion amazunguliridwa ndi ma chloride ion ochokera ku choline chloride ndikulowetsedwa mu yankho.

Kuti zitsulo zina monga cobalt kapena nickel zitulutsidwe, choline chloride ndi ethylene glycol ndizofunikira. Pakati pa zinthuzi, choline chloride yokha ndi yomwe imayamwa bwino ma microwave. Ofufuzawa adamiza zinyalala za batri mu solvent ndipo adagwiritsa ntchito kuwala kwa microwave, zomwe zidapangitsa kuti lithiamu yosankhidwa itulutsidwe kuchokera ku zitsulo zina.

Kugwiritsa ntchito mphamvu ya microwave munjira imeneyi kuli kofanana ndi kutentha chakudya mwachangu mu uvuni wa microwave kukhitchini. Mphamvu imasamutsidwa mwachindunji ku mamolekyulu, zomwe zimapangitsa kuti izi zichitike mwachangu kwambiri kuposa njira zachikhalidwe zotenthetsera.

Ofufuzawo adapeza kuti ndi njira ya microwave, kutulutsa 87% ya lithiamu kumatenga mphindi 15, pomwe kupeza mlingo womwewo wobwezeretsanso pogwiritsa ntchito mafuta ofunda m'bafa kumafuna maola 12. Njira yatsopanoyi imawongolera kwambiri kudalirika kwachuma komanso kuwononga chilengedwe kwa mabatire a lithiamu-ion, zomwe zikupereka yankho latsopano lokhazikika ku vuto lomwe likukula padziko lonse lapansi.

Kuti mudziwe zambiri zamakampani ndi zinthu, chonde titumizireni uthenga:
