Imoto yamandla entsha i-lithium anode impahla iqukethei-tungsten oxide WO3 nanoparticles.

Ekukhiqizeni izimoto zamandla amasha, ukusetshenziswa kwe-lithium anode impahla equkethe i-yellow tungsten oxide inganikeza amandla ebhethri lamandla futhi ithuthukise ukusebenza kwezindleko zemoto.
Ngokuqondene nemboni yezimoto zamandla amasha, ingxenye yebhethri iwumgogodla wobuchwepheshe obuthathu bukagesi.Ngokwezisebenzi ezifanele, ngo-2019, iqoqo lokuqala lesistimu yebhethri yemoto yamandla entsha ye-energy density engu-160Wh/Kg noma ngaphezulu. , isamba samamodeli angu-15, ngokulandelana kwawo, BYD, CITIC Guoan, GAC Group, Jianghuai Ting, Ningde Times, PHYLION, DFD, Tianjin Jiewei, Shanghai DLG, Ningbo Viri.Amasistimu ebhethri abawakhiqizile wonke asekelwe kumabhethri angapheli.Ochwepheshe bakhomba ukuthi ohlelweni lokukhiqiza izinto ze-lithium anode, ukwengeza i-nano yellow tungsten oxide kungenza ibhethri libe nokusebenza kwezindleko eziphakeme, bese ithuthukisa ukuncintisana kwezimoto zamandla amasha emakethe yamazwe ngamazwe.Isizathu esenza izinhlayiya ze-tungsten oxide eziphuzi ezinosayizi we-nano esetshenziswa njenge-lithium anode material ukuthi i-yellow tungsten oxide inenzuzo yokuminyana kwamandla aphezulu kanye nenani eliphansi.

I-Nano yellow tungsten trioxide, i-WO3 powder, iyinhlangano ekhethekile ye-N-type semiconductor material, engasetshenziswa ukulungisa izinto ze-electrode ezibiza izindleko, okungukuthi, ibhethri ye-lithium eshaja ngokushesha ayinakho ukusebenza okuphezulu kwe-electrochemical kuphela, kodwa futhi nezindleko zokukhiqiza eziphansi.Uma kuqhathaniswa namabhethri afanayo emakethe, amabhethri e-lithium aqukethe i-nanometer tungsten powder anohlu olubanzi lokusetshenziswa, futhi anganikeza amandla anele ezimotweni zamandla amasha, amathuluzi kagesi, omakhalekhukhwini besikrini sokuthinta, amalaptop namanye amadivaysi.

Amabhethri e-Ternary lithium kanye namabhethri e-lithium iron phosphate ahlala emakethe.Nokho, anezihibe ezithile, njengesikhala esilinganiselwe sokuthuthukisa ukuminyana kwamandla.Kulokhu, ososayensi bagxile ocwaningweni lwezinto ze-anode ne-cathnode.

Umkhuba wokuthuthukiswa kobuchwepheshe bezinto ze-lithium cathode

I-Orthosilicate, i-lithium-rich rich manganese-based based, sulfide-based cathode materials are the current research hot.In theory, orthosilicate can allow exchange of 2 Li+, which has a high theory umthamo othize, kodwa inqubo yokukhululwa, umthamo wangempela. isigamu kuphela somthamo wetiyori.Ngaphezu kwamandla athile aphezulu, isisekelo se-lithium esicebile se-manganese sinenzuzo yenani elifanele.Ngaphambi kwalokhu, kuyadingeka ukuthola indlela yokukhiqiza efanelekile.Izinto ze-cathode ezisekelwe ku-sulphur zinomthamo wamandla we-2600Wh / kg, kodwa ukunwetshwa kwevolumu kulula ukwenzeka kwinqubo yokushaja nokukhipha, okudinga ukuthuthukiswa.
Umkhuba wokuthuthukiswa kobuchwepheshe bezinto ze-lithium anode

I-graphene, i-lithium titanate kanye ne-nano yellow tungsten oxide yizinto ezishiseka kakhulu ze-lithium anode. izinto ze-anode.I-Lithium titanate inokuphila komjikelezo omude, kuze kube izikhathi ezingaphezu kuka-10,000, futhi ingashajwa ngokushesha, ifaneleka kakhulu indawo ayidingi insimu yokugcina amandla.I-Nano yellow tungsten oxide iyinto ekhethekile ye-electrode enamandla okucabanga angu-693mAh/g nokusebenza okuhle kakhulu kwe-electrochromic.Ngaphezu kwalokho, inezinzuzo zamanani aphansi, izinqolobane eziningi kanye nokungewona ubuthi.

Sengiphetha, i-nano-size tungsten oxide WO3 ingasetshenziswa njengempahla ye-electrode futhi isetshenziswe ezimotweni zamandla amasha.

I-Guangzhou Hongwu Material Technology Co., Ltd. iyahlinzekaI-nano yellow tungsten trioxide WO3ngobuningi, ngokukhishwa kwanyanga zonke okungaphezu kwamathani angu-2.Siqhutshwa izimoto ezintsha zamandla, kancane kancane sandisa umugqa wokukhiqiza, sihlinzeka ngemikhiqizo engcono kakhulu emakethe, futhi senza umnikelo onesizotha emkhakheni omusha wamandla.
