Kusuka ku MIT, IMassachusetts Institute of Technology, isanda kumemezela ukuthi elinye lamaqembu abo ocwaningo likwazile ukuklama ibhethri elisha le-lithium-oxygen lokho kuthuthukisa ngokubonakalayo empilweni elusizo nasekusebenzeni kahle kwamandla kuzo zonke izinhlobo zangaphambilini. Njengemininingwane, uma kuqhathaniswa namabhethri e-lithium-ion, amamodeli e-lithium-oxygen avelela ukunikezela kwabantu abaphezulu kakhulu. Ngokuqondene nedatha enjalo, kufanele kuqashelwe ukuthi elinye lalawa mabhethri lingahle lisebenze kangcono ngama-90%, likhanye kahlanu futhi libe namandla ngokuphindwe kayishumi. Elinye lamaphuzu alo amabi, aqhubeka nokuqhathanisa, ukuthi linikeza kuphela imijikelezo ekhokhiswayo engaba ngu-2.000 XNUMX.
Ngenxa yezimfanelo zayo ezinhle kakhulu, amaqembu amaningi abacwaningi asetshenziselwe ukuthuthukisa lawo maphuzu amabi, kuze kube manje, enza ukuthi kungasebenzi. Ngenxa yemiphumela etholwe ngabaphenyi be-MIT, umnyango omusha ungavulwa, ikakhulukazi ngaphakathi kwemakethe efana naleyo ye- izimoto zikagesi futhi i amadivayisi kagesi aphathekayo.
Ibhethri le-MIT's lithium-oxygen lidlula amabala amnyama amaningi ekukhishweni kwangaphambilini.
Njengoba sishilo, lolu hlobo olusha lwamabhethri lusethula uchungechunge lwe- izinkinga lokho kuzenza zingasebenzi, kufaka phakathi ukwengeza kumijikelezo yomthwalo namuhla balahlekelwa amandla abo amaningi ngendlela yokushisa, yehlisa isithunzi masinyane futhi kudinga izingxenye ezengeziwe ezibizayo inikezelwe ukupompa umoya-mpilo ngaphakathi nangaphandle kwezakhiwo, okuthi zona, ngokungafani nezendabuko, zivule iseli.
Mayelana nomsebenzi owenziwe ososayensi be-MIT ngokubhekisele kumabhethri e-lithium-oxygen, kufanele kuqashelwe ukuthi bazuzile yenza ukuhluka kwamakhemikhali ebhethri ngendlela yokuthi manje ibizovalwa ngokuphelele ukuze isetshenziswe njengebhethri ejwayelekile. Lokhu kuguqulwa kubangela ukuthi i-voltage yehliswe amahlandla ayisihlanu, okugcina kuholele ekukhokhweni okushesha kakhulu nokusebenza okuthuthukile, ngenkathi kugwenywa isimo se-oxygen esinamandla kusho ukuthi impilo yayo elusizo inganwetshwa.
Ngesikhathi sokuhlolwa okwenziwe kulolu hlelo, uhlobo olusha lwadalulwa kumjikelezo we-120 nokukhishwa kwemijikelezo ekhombisa ukulahleka okungaphansi kuka-2%, okusho ukuthi leli bhethri lizoba nempilo ende esebenzisekayo. Ithimba eliphethe ukuthuthukiswa kwale phrojekthi lithemba ukuthi vivinya uhlobo olulungiselelwe phakathi no-2017.
