Galimoto yatsopano yamphamvu ya lithiamu anode ili nditungsten okusayidi WO3 nanoparticles.

Popanga magalimoto atsopano amphamvu, kugwiritsa ntchito lithiamu anode zinthu zomwe zili ndi yellow tungsten oxide zimatha kupereka mphamvu kwa batri yamagetsi ndikuwongolera mtengo wagalimoto.
Ponena za mafakitale amagetsi atsopano, gawo la batri ndilo maziko a teknoloji yamagetsi atatu. Malingana ndi ogwira nawo ntchito, mu 2019, gulu loyamba la mphamvu yamagetsi yamagetsi amagetsi a 160Wh / Kg kapena kuposa. , chiwerengero cha zitsanzo za 15, motsatira BYD, CITIC Guoan, GAC Group, Jianghuai Ting, Ningde Times, PHYLION, DFD, Tianjin Jiewei, Shanghai DLG, Ningbo Viri.Makina a batri omwe adapanga onse amachokera ku mabatire a ternary. kuti popanga zida za lithiamu anode, kuwonjezera nano yellow tungsten okusayidi kungapangitse batire kukhala ndi mtengo wokwera mtengo, ndikuwongolera kupikisana kwa magalimoto amagetsi atsopano pamsika wapadziko lonse lapansi. amagwiritsidwa ntchito ngati zinthu za lithiamu anode ndikuti chikasu cha tungsten oxide chili ndi mwayi wokhala ndi mphamvu zambiri komanso mtengo wotsika.

Nano yellow tungsten trioxide, WO3 ufa, ndi wapadera inorganic N-mtundu semiconductor zakuthupi, zomwe zingagwiritsidwe ntchito pokonzekera zotsika mtengo zipangizo elekitirodi, ndiko kuti, okonzeka kudya nawuza batire lifiyamu ali osati apamwamba electrochemical ntchito, komanso mtengo wotsika kupanga.Poyerekeza ndi mabatire ofanana mu msika, mabatire a lithiamu omwe ali ndi nanometer tungsten ufa ali ndi ntchito zambiri, ndipo amatha kupereka mphamvu zokwanira zamagalimoto atsopano amphamvu, zida zamagetsi, mafoni a m'manja, ma laputopu ndi zipangizo zina.

Mabatire a Ternary lithiamu ndi mabatire a lithiamu iron phosphate amatenga gawo lalikulu pamsika.

Kukula kwaukadaulo kwa zida za lithiamu cathode

Orthosilicate, wosanjikiza lifiyamu wolemera manganese ofotokoza, sulfide ofotokoza cathode zipangizo ndi panopa kafukufuku otentha.Mwa chiphunzitso, orthosilicate akhoza kulola kuwombola 2 Li +, amene ali mkulu ongolankhula mphamvu yeniyeni, koma mu ndondomeko kumasulidwa, mphamvu yeniyeni. ndi theka la theka la theoretical capacity.Kuphatikiza ndi mphamvu zenizeni zenizeni, wosanjikiza lifiyamu wolemera manganese m'munsi ali ndi ubwino wa mtengo wololera.Izi zisanachitike, m'pofunika kupeza njira yoyenera yopangira.Zipangizo za sulfure zochokera ku cathode zimakhala ndi mphamvu zowonjezera mphamvu za 2600Wh / kg, koma kuwonjezereka kwa voliyumu kumakhala kosavuta kuchitika poyendetsa ndi kutulutsa, zomwe ziyenera kukonzedwa bwino.
Kukula kwaukadaulo kwazinthu za lithiamu anode

Graphene, lithiamu titanate ndi nano yellow tungsten oxide ndizokonda kwambiri lifiyamu anode materials. zinthu za anode.Lithium titanate ili ndi moyo wautali wozungulira, mpaka nthawi zopitilira 10,000, ndipo imatha kuyimbidwa mwachangu, yoyenera kwambiri pamalopo sikutanthauza kusungirako mphamvu.Nano yellow tungsten oxide ndi chinthu chapadera cha elekitirodi chokhala ndi mphamvu yofikira 693mAh/g ndikuchita bwino kwambiri kwa electrochromic.Kuonjezera apo, ili ndi ubwino wa mtengo wotsika, nkhokwe zambiri komanso zopanda poizoni.

Pomaliza, nano-kakulidwe tungsten okusayidi WO3 angagwiritsidwe ntchito ngati elekitirodi chuma ndi ntchito magalimoto mphamvu zatsopano.

Guangzhou Hongwu Material Technology Co., Ltdnano yellow tungsten trioxide WO3chochulukira, ndi kutulutsa mwezi uliwonse kuposa matani awiri.Motsogozedwa ndi magalimoto amagetsi atsopano, tikukulitsa pang'onopang'ono mzere wopangira, kupereka zinthu zabwino pamsika, ndikupanga gawo lochepetsetsa kumunda watsopano wamagetsi.
