Isithuthi samandla esitsha se-lithium anode siqulethetungsten oxide WO3 nanoparticles.
Kwimveliso yezithuthi zamandla amatsha, ukusetyenziswa kwe-lithium anode impahla equkethe i-yellow tungsten oxide inokubonelela ngamandla kwibhetri yamandla kunye nokuphucula ukusebenza kweendleko zesithuthi.
Ngokubhekiselele kushishino lwezithuthi zamandla amatsha, inxalenye yebhetri iyona nto ingundoqo yobuchwepheshe bombane obuthathu.Ngokwabasebenzi abachaphazelekayo, ngo-2019, ibhetshi yokuqala yenkqubo yebhetri yemoto yamandla entsha ye-160Wh / Kg okanye ngaphezulu. , iyonke imodeli ye-15, ngokulandelanayo BYD, CITIC Guoan, GAC Group, Jianghuai Ting, Ningde Times, PHYLION, DFD, Tianjin Jiewei, Shanghai DLG, Ningbo Viri.Iinkqubo zebhetri abaziphuhlisileyo zonke zisekelwe kwiibhetri ze-ternary. ukuba kwinkqubo yokuvelisa izinto ze-lithium anode, ukongeza i-nano yellow tungsten oxide ingenza ibhetri ibe neendleko eziphezulu zokusebenza, kwaye emva koko kuphuculwe ukukhuphisana kwezithuthi zamandla amatsha kwiimarike zamazwe ngamazwe. isetyenziswe njengezinto ze-lithium anode kukuba i-yellow tungsten oxide inenzuzo yobuninzi bamandla kunye nexabiso eliphantsi.
Nano yellow tungsten trioxide, WO3 umgubo, yinto ekhethekileyo ye-N-type semiconductor material, engasetyenziselwa ukulungiselela izinto ze-electrode ezinexabiso, oko kukuthi, ibhetri ye-lithium ekhawulezayo etshajayo ayinayo kuphela ukusebenza okuphezulu kwe-electrochemical, kodwa kunye neendleko eziphantsi zokuvelisa.Xa kuthelekiswa neebhetri ezifanayo kwi kwimarike, iibhetri ze-lithium eziqukethe i-nanometer tungsten powder zineendlela ezibanzi zokusetyenziswa, kwaye zinokubonelela ngamandla aneleyo kwizithuthi zamandla amatsha, izixhobo zombane, iifowuni eziphathwayo, iilaptops kunye nezinye izixhobo.
Iibhetri ze-Ternary ze-lithium kunye neebhetri ze-lithium iron phosphate zithatha indawo ephambili yemarike.Nangona kunjalo, baneengxaki ezithile, ezifana nesithuba esincinci sokuphucula ubuninzi bamandla.Ukuza kuthi ga ngoku, izazinzulu zijolise kuphando lwezinto ze-anode kunye ne-cathnode.
Itekhnoloji yophuhliso lwezixhobo ze-lithium cathode
I-Orthosilicate, i-lithium-rich manganese-based based, i-sulfide-based based cathode materials are the current research hot.In theory, orthosilicate can allow the exchange of 2 Li +, which has a high theory specific capacity, kodwa kwinkqubo yokukhululwa, amandla okwenene. sisiqingatha kuphela somthamo wethiyori.Ukongezelela kumandla athile aphezulu, isiseko se-lithium esityebileyo se-manganese sinenzuzo yexabiso elifanelekileyo.Ngaphambi koku, kuyimfuneko ukufumana indlela efanelekileyo yokuvelisa.Izixhobo ze-cathode ezisekelwe kwi-Sulfur zinobuninzi bamandla we-2600Wh / kg, kodwa ukwandiswa kwevolumu kulula ukwenzeka kwinkqubo yokutshaja kunye nokukhupha, efuna ukuphuculwa.
Itekhnoloji yophuhliso lwezixhobo ze-lithium anode
I-graphene, i-lithium titanate kunye ne-nano yellow tungsten oxide yizona zinto zinomdla kakhulu ze-lithium anode. izixhobo anode.I-Lithium titanate inobomi bomjikelezo omde, ukuya kuthi ga kumaxesha angama-10,000, kwaye inokuhlawuliswa ngokukhawuleza, ifaneleke ngakumbi indawo ayifuni indawo yokugcina amandla.I-Nano yellow tungsten oxide yinto ekhethekileyo ye-electrode ene-theory ye-693mAh / g kunye nokusebenza okugqwesileyo kwe-electrochromic.Ukongeza, ineenzuzo zexabiso eliphantsi, oovimba abaninzi kunye ne-non-toxicity.
Ukuqukumbela, i-nano-size tungsten oxide WO3 ingasetyenziselwa izinto ze-electrode kwaye isetyenziswe kwizithuthi zamandla amatsha.
I-Guangzhou Hongwu Material Technology Co., Ltd. iyabonelelanano yellow tungsten trioxide WO3ngobuninzi, kunye nemveliso yenyanga engaphezu kweetoni ezi-2.Ukuqhutywa zizithuthi zamandla amatsha, ngokuthe ngcembe sandisa umgca wemveliso, ukubonelela ngeemveliso ezingcono kwimarike, kwaye senze igalelo elincinci kwintsimi yamandla amatsha.
