Njira yolondolera kupangidwa kwa mabatire am'badwo wotsatira komanso okhalitsa

Tekinoloje zaukhondo komanso zogwira mtima zosungira mphamvu ndizofunikira kuti pakhazikitsidwe malo opangira mphamvu zowonjezera.Mabatire a lithiamu-ion ali kale kwambiri pazida zamagetsi zamunthu, ndipo akulonjeza ofuna kukhala odalirika osungira mulingo wa gridi ndi magalimoto amagetsi.Komabe, kupititsa patsogolo kwina kumafunika kuti apititse patsogolo mitengo yawo yolipiritsa komanso moyo wawo wonse.

Kuti athandizire kupanga mabatire othamanga komanso okhalitsa ngati amenewa, asayansi akuyenera kumvetsetsa zomwe zimachitika mkati mwa batire yogwira ntchito, kuti adziwe zomwe batire likuchita.Pakadali pano, kuwona zida za batri zomwe zimagwira ntchito zimafunikira njira zaukadaulo za synchrotron X-ray kapena ma electron microscopy, zomwe zimakhala zovuta komanso zodula, ndipo nthawi zambiri sizitha kujambula mwachangu kuti zitha kusintha kusintha komwe kumachitika muzinthu zamagetsi zamagetsi zamagetsi.Chotsatira chake, mphamvu ya ion pautali wa tinthu tating'onoting'ono tating'onoting'ono komanso pamalonda okhudzana ndi malonda othamanga mofulumira amakhalabe osadziwika.

Ofufuza a ku yunivesite ya Cambridge agonjetsa vutoli popanga njira yotsika mtengo ya lab-based Optical microscopy kuti aphunzire mabatire a lithiamu-ion.Adasanthula tinthu tating'ono ta Nb14W3O44, yomwe ili m'gulu lazinthu zothamangitsa kwambiri za anode mpaka pano.Kuwala kowoneka kumatumizidwa mu batri kudzera pawindo laling'ono lagalasi, kulola ochita kafukufuku kuti ayang'ane kayendetsedwe ka kayendetsedwe kake mkati mwa tinthu tating'onoting'ono, mu nthawi yeniyeni, pansi pa zochitika zenizeni zopanda kufanana.Izi zimawululira kutsogolo ngati ma lithiamu-concentration gradients akuyenda mu tinthu tating'onoting'ono tating'ono, zomwe zimapangitsa kuti pakhale zovuta zamkati zomwe zidapangitsa kuti tinthu tating'onoting'ono tiphwanyike.Kuphulika kwa Particle ndi vuto kwa mabatire, chifukwa kungayambitse kutsekedwa kwa magetsi pazidutswa, kuchepetsa mphamvu yosungirako batire.Wolemba nawo wina Dr Christoph Schnedermann, wa ku Cambridge's Cavendish Laboratory, anati:

Kuthekera kwapamwamba kwa njira ya microscope ya kuwala kunathandiza ochita kafukufuku kuti afufuze kuchuluka kwa tinthu tating'onoting'ono, ndikuwulula kuti kusweka kwa tinthu kumakhala kofala kwambiri ndi mitengo yapamwamba ya delithiation komanso mu tinthu tambirimbiri."Zomwe zapezazi zimapereka mfundo zogwirira ntchito zochepetsera kuwonongeka kwa tinthu tating'ono ndi kutha mphamvu m'gululi lazinthu," akutero wolemba woyamba Alice Merryweather, wochita nawo PhD ku dipatimenti ya Cavendish Laboratory and Chemistry ku Cambridge.

Kupita patsogolo, ubwino wofunikira wa njira - kuphatikizapo kupeza deta mofulumira, kusamvana kwa tinthu ting'onoting'ono, ndi mphamvu zowonjezera - zidzathandiza kufufuza kwina kwa zomwe zimachitika mabatire akalephera komanso momwe angapewere.Njirayi ingagwiritsidwe ntchito pophunzira pafupifupi mtundu uliwonse wa zinthu za batri, zomwe zimapangitsa kukhala gawo lofunika kwambiri pakupanga mabatire am'badwo wotsatira.
