Incazelo:
I-Nano-germanium inezinzuzo zegebe lebhande elincane, i-coefficient yokumuncwa okuphezulu, nokuhamba okuphezulu. Uma isetshenziswa kungqimba lokumuncwa lwamaseli elanga, inganweba ngempumelelo ukumuncwa kwe-infrared band spectrum yamaseli elanga.
I-Germanium isiphenduke into ethembisa kakhulu ye-electrode engalungile yamabhethri e-lithium-ion ngenxa yomthamo wayo wetiyori ophakeme.
Umthamo wethiyori we-germanium ngu-1600 mAh/g, futhi umthamo wevolumu uphezulu njengo-8500 mAh/cm3. Izinga lokusabalalisa le-Li+ ku-Ge material licishe liphindwe izikhathi ezingu-400 kunelika-Si, futhi ukuqhutshwa kwe-electronic kuphindwe izikhathi ezingu-104 kune-Si, ngakho-ke i-germanium ifaneleka kakhulu kumadivayisi amanje nanamandla aphezulu.
Ucwaningo lulungise i-nano-germanium-tin/carbon composite material. I-carbon material ingathuthukisa ukuqhutshwa kwe-germanium ngenkathi ivumelanisa nokushintsha kwevolumu yayo. Ukwengezwa kwe-tin kungaqhubeka nokuthuthukisa ukuqhutshwa kwezinto. Ngaphezu kwalokho, izingxenye ezimbili ze-germanium ne-tin zinamandla ahlukene okukhipha/ukufakwa kwe-lithium. Ingxenye engabambi iqhaza ekuphenduleni ingasetshenziswa njenge-matrix ukuze ivimbele ukushintsha kwevolumu yenye ingxenye phakathi nenqubo yokushaja nokukhipha, ngaleyo ndlela kuthuthukiswe ukuzinza kwesakhiwo se-electrode engalungile.
Isimo Sesitoreji:
Ama-nanopowder e-Gerinium Ge kufanele agcinwe endaweni evaliwe, gwema ukukhanya, indawo eyomile. Isitoreji sezinga lokushisa legumbi silungile.
