Abacwaningi e-Samsung Institute of Advanced Technology (SAIT), ngokubambisana nesikhungo se-R&D sakwaSamsung eJapan, bathole indlela yabo yebhethri lesimo esiqinile esisebenzayo. Lawa mabhethri esimo esiqinile angangena esikhundleni samabhethri e-lithium-ion avamile ngekusasa elibonakalayo.
Kodwa-ke, ochwepheshe bakholelwa ukuthi ngeke kube yinqubo esheshayo futhi kuzothatha isikhathi, mhlawumbe ekupheleni kuka-2024. Amabhethri e-solid-state abelokhu esezingqondweni zezinkampani eziningi ezinkulu ngenxa yezinzuzo zazo ngaphezu kwamabhethri e-lithium-ion. . Izinkampani eziningi sezivele zisebenza ngakho. Nokho, kusewumsebenzi ongaphelele ukukhiqiza nokudayisa lawa mabhethri.
Ibhethri yesimo esiqinile ye-Samsung
AbakwaSamsung, ngakolunye uhlangothi, benze lokhu kwaba nokwenzeka ngocwaningo lwabo olubanzi nobunjiniyela obukhaliphile. Abacwaningi bakwaSamsung basebenzise ungqimba oluncane kakhulu (ama-micrometer angu-5) wekhabhoni yesiliva ku-anode ye- amabhethri, okuvimbela ukwakheka kwama-dendrites.
Kuhlanganiswe nobunye ubuchwepheshe, leli bhethri selinamandla aphindwe kabili ukuminyana kwamabhethri e-lithium-ion kanye nobubanzi obungafika ku-800 km. Futhi, ingashajwa izikhathi ezingaba ngu-1000. Ngalokhu, ingahlinzeka cishe ngamamayela angama-800,000 engqikithi yezimoto zikagesi.
Uma kubhekwa iqiniso lokuthi inomthamo omkhulu wamandla kunebhethri ye-lithium-ion, azoba amabhethri ahlangene. Ngalokhu, kuzoba nesikhala esengeziwe ezimotweni zikagesi ezingase zisetshenziselwe izinhloso ezehlukene.
Okuzuzwe yi-Samsung kufana nechopho leqhwa, uma kucatshangelwa amandla amabhethri esimo esiqinile. Ngokusho kwe Ochwepheshe, ingashintsha ikusasa lamabhethri, kokubili ezimotweni zikagesi nomakhalekhukhwini.
Kungani Amabhethri Esifunda Esiqinile Angase Aguquke
- Ngokungafani namabhethri e-lithium-ion aholela ekwakhekeni kwe-dendrite ekushajweni okusheshayo, okungagcina kuholele emlilweni, amabhethri e-solid state awakhi ama-dendrites. Ama-dendrites avame ukwakhiwa ngenxa ye-electrolyte ewuketshezi; Nokho, amabhethri esimo esiqinile anama-electrolyte aqinile.
- Ngokuka-John B Goodenough, manje osesebenza ngamabhethri e-solid-state futhi oyindoda ephumelele impumelelo yamabhethri e-lithium-ion, uthe amabhethri e-solid state anezikhathi ezingu-2.2 kuya kwezi-5 ukuminyana kwamandla amabhethri avamile.
- Ingaba nemijikelezo yokushaja efika ku-1200 ngokuwohloka kweseli okuphansi. Ngokungafani namabhethri esimo esiqinile, amabhethri e-lithium ion azobhekana nokuwohloka okufanayo ngamashaji angama-500 kuphela.
- Amabhethri esimo esiqinile angasebenza phakathi kwezinga lokushisa elisuka ku -20 degrees Celsius kuya ku-60 degrees Celsius
- Ngamafuphi, lawa amandla aphezulu aphezulu, amabhethri ahlala isikhathi eside futhi aphephile uma kuqhathaniswa namaseli e-lithium ion.
Ngaphezu kwalokho, ngokusho kukaMnu. Goodenough, lezi zingenziwa ngezinto ezilungele umhlaba ezinganciphisa izindleko zamabhethri. Kodwa-ke, namuhla izinkampani zisebenzisa imali eshisiwe ukuthuthukisa lawa mabhethri. Kuze kube manje, yi-Samsung kuphela ekwazile ukwakha ibhethri elisebenzayo, okuzothi, ngakolunye uhlangothi, libize.
Kodwa-ke, ngobuchwepheshe nocwaningo oluqhubekayo namuhla, ibhethri lesimo esiqinile elithengekayo alikho kude emkhathizwe.
