New simba mota lithium anode zvinhu zvinetungsten oxide WO3 nanoparticles.
Mukugadzirwa kwemotokari dzemagetsi matsva, kushandiswa kwe lithium anode zvinhu zvine yellow tungsten oxide zvinogona kupa simba rebhatiri remagetsi uye kuvandudza mutengo wekuita kwemotokari.
Nezve indasitiri yemotokari yemagetsi, chikamu chebhatiri ndiyo musimboti weiyo matatu-yemagetsi tekinoroji.Sekureva kwevashandi vakakodzera, muna 2019, batch yekutanga yemagetsi emagetsi bhatiri system simba density ye160Wh / Kg kana kupfuura. , huwandu hwemhando gumi neshanu, zvichiteerana BYD, CITIC Guoan, GAC Group, Jianghuai Ting, Ningde Times, PHYLION, DFD, Tianjin Jiewei, Shanghai DLG, Ningbo Viri.Magadzirirwo ebhatiri avakagadzira ese akavakirwa pamabhatiri e ternary.Professional point out kuti mukugadzirwa kwe lithium anode zvinhu, kuwedzera nano yellow tungsten oxide kunogona kuita kuti bhatiri rive nemutengo wepamusoro, uyezve kuvandudza kukwikwidzana kwemotokari itsva dzemagetsi mumusika wepasi rose. Chikonzero nei yellow nano-sized tungsten oxide particles zviri inoshandiswa se lithium anode zvinhu ndeyekuti yero tungsten oxide ine mukana wepamusoro simba density uye mutengo wakaderera.
Nano yellow tungsten trioxide, WO3 hupfu, inokosha inorganic N-mhando semiconductor zvinhu, zvinogona kushandiswa kugadzira zvinodhura-zvinobudirira electrode zvinhu, kureva, yakagadzirirwa kukurumidza kuchaja lithium bhatiri haina chete yakakwirira electrochemical performance, asiwo yakaderera mutengo wekugadzira.Kuenzaniswa nemabhatiri akafanana mu pamusika, mabhatiri etimumu ane nanometer tungsten powder ane huwandu hwakawanda hwekushandisa, uye anogona kupa simba rakakwana kumotokari itsva dzemagetsi, maturusi emagetsi, touch-screen mobile phones, laptops nemamwe madivayiri.
Ternary lithium mabhatiri uye lithium iron phosphate mabhatiri anotora chikamu chikuru chemusika.Zvisinei, vane zvimwe zvipingamupinyi, senge nzvimbo shoma yekuvandudzwa kwesimba remagetsi.Kusvika kumagumo aya, masayendisiti anotarisa pakutsvaga kweanode uye cathnode zvinhu.
Tekinoroji yekuvandudza maitiro e lithium cathode zvinhu
Orthosilicate, layered lithium-rich manganese-based, sulfide-based cathode materials ndiyo yemazuva ano tsvakurudzo inopisa.In theory, orthosilicate inogona kubvumira kuchinjana kwe2 Li +, iyo ine yakakwirira theoretical chaiyo simba, asi mukusunungurwa kwemaitiro, simba chairo. inongova hafu ye theoretical capacity.Kuwedzera kune yakakwirira chaiyo simba, layered lithium rich manganese base ine mukana wemutengo unonzwisisika.Izvi zvisati zvaitika, zvakakosha kuwana nzira yakakodzera yekugadzira.Sulfur-based cathode zvinhu zvine simba re 2600Wh / kg, asi kuwedzera kwevhoriyamu kuri nyore kuitika mukugadzirisa uye kuburitsa, iyo inoda kuvandudzwa.
Tekinoroji yekuvandudza maitiro e lithium anode zvinhu
Graphene, lithium titanate uye nano yellow tungsten oxide ndiyo inonyanya kufarira lithium anode zvinhu. anode zvinhu.Lithium titanate ine hupenyu hurefu hwekutenderera, kusvika kune anopfuura 10,000 nguva, uye inogona kukurumidza kubhadhariswa, yakanyanya kukodzera nzvimbo haidi simba rekuchengetedza simba.Nano yellow tungsten oxide chinhu chakakosha che electrode ine theoretical kugona 693mAh/g uye yakanakisa electrochromic performance.Mukuwedzera, ine zvakanakira mutengo wakaderera, yakawanda yekuchengetedza uye isiri-chepfu.
Mukupedzisa, nano-saizi tungsten oxide WO3 inogona kushandiswa se electrode zvinhu uye kushandiswa mumagetsi matsva emagetsi.
Guangzhou Hongwu Material Technology Co., Ltd. iri kupanano yellow tungsten trioxide WO3muhuwandu, neinobuda pamwedzi inodarika matani maviri.Tichityairwa nemotokari dzemagetsi matsva, tiri kuwedzera zvishoma nezvishoma mutsara wekugadzira, tichipa zvigadzirwa zviri nani zvemusika, uye tichipa mupiro une mwero kumunda wesimba idzva.
