Uhlalutyo oluthelekisayo lwee-supercapacitors ezinxulumeneyo, iibhetri ze-lithium kunye neebhetri zegraphene
Kwaye ii-supercapacitors zimbini iintlobo zezixhobo zokugcina amandla ezinamandla amakhulu kunye nesicelo esibanzi. Imigaqo yabo, iimpawu kunye nobubanzi bokusetyenziswa zihlukile, kwaye ngamnye unenzuzo yakhe. Ukususela ekuqaleni, igraphene iye yanconywa njengento eguqukayo yokugcina amandla ngenxa yombane wayo onamandla.
Imizuzu emi-5 ukubiza! Iikhilomitha ezingama-500! Ibhetri yegraphene ibonelelwa ngaphandle kokukhathazeka!
Igraphene yifilim ethe tyaba ye monoatomic eyenziwe ziiathom zekhabhoni. Yi-0.34 yeenanometers kuphela ubukhulu. Umaleko omnye uphinda-phinda izihlandlo ezili-150,000 ubukhulu beenwele zomntu. Ngoku yeyona nto incinci kwaye inamandla i-nanomaterial eyaziwayo emhlabeni, inokuhambisa ukukhanya okulungileyo kunye nokukwazi ukusonga. Ngenxa yokuba kukho umaleko omnye kuphela weeathom kwaye ii-electron zivalelwe kwinqwelo-moya enye, igraphene nayo ineempawu ezintsha kraca zombane. IGraphene yeyona nto iqhubayo ehlabathini. I-graphene composite powder conductive yongezwa kwibhetri ye-lithium yefowuni yendabuko ukuphucula intlawulo yebhetri kunye nokukhupha ukusebenza kunye nobomi bomjikelezo.
Nangona kunjalo, ubunzima bobugcisa kwinkqubo yokulungiselela ngowona mqobo omkhulu ekuqondeni ukubanakho kwegraphene. Okwangoku, uninzi lwetekhnoloji yebhetri yegraphene isekwinqanaba lovavanyo lophuhliso. Ngaba ngokwenene kufuneka silinde ixesha elide?
Kutshanje, iPolycarbon Power, icandelo eliphantsi kweZhuhai Polycarbon Composite Materials Co., Ltd., iphuhlise imveliso yebhetri yegraphene yorhwebo, izisa iibhetri zegraphene kwinqanaba lelebhu kwimarike yebhetri, kwaye yayisombulula ngempumelelo ingxaki yeebhetri zegraphene. . Ukungazinzi, isantya sokutshaja esicothayo, kunye nomthamo ophantsi webhetri esele ikhona.
I-Zhuhai Polycarbon yamkela ingqikelelo yoyilo lolungelelwaniso olubanzi lokusebenza, yazisa ngobuchule izinto ezintsha zekhabhoni esekwe kwigraphene kwi-electrode esebenzayo nengalunganga yebhetri ye-capacitor, kwaye idibanisa ii-supercapacitors eziqhelekileyo kunye neebhetri ezinamandla aphezulu ukuphuhlisa uhlobo olutsha lwebhetri ephezulu yokusebenza okuphezulu. .
Okokuqala, iibhetri zegraphene ziya kuqala ukusetyenziswa kwiibhetri zemoto zombane. Kulindeleke ukuba babe nako ukudibana nabasebenzisi ekupheleni kwalo nyaka okanye ekuqaleni konyaka ozayo. Kwisiqingatha sesibini sonyaka ozayo, iibhetri zegraphene zorhwebo kwindawo yezicelo zebhetri yefowuni ziya kukubona. Ngelo xesha, iibhetri zeselula Ubomi bokutshaja ngokukhawuleza kunye nemiba yokhuseleko inokusombulula nganye nganye.
Umsebenzi weZhuhai Polycarbon Composite Materials Co., Ltd. wazisa ukuba iibhetri ze-lithium iron phosphate kunye neebhetri ze-lithium manganese acid ziibhetri eziqhelekileyo zombane kwimarike. Ezi ntlobo zintathu zeebhetri zineenzuzo kunye neengxaki zazo, kodwa abathengi beemoto banokukhetha iibhetri ezahlukeneyo ngokwezinto ezintle kunye nezibi. Kukwakho nebhetri yegraphene, eyintshatsheli entsha enokuthintela ukutsha okuzenzekelayo njengebhetri kaTesla.
Amandla ePolycarbon abambe iteknoloji yokulungiselela iibhetri zegraphene. Ukongeza i-graphene kwizinto ezilungileyo ze-electrode kunye ne-electrode efanelekileyo yebhetri ye-lithium kunciphisa ukuchasana kwangaphakathi kwebhetri, ngaloo ndlela ukuqonda ukutshaja kunye nokukhupha ngokukhawuleza, kunye nokuphucula kakhulu ubomi bomjikelezo webhetri. Ikwaphucula ukusebenza kwebhetri ukumelana namaqondo obushushu aphezulu naphantsi. Le yiteknoloji engundoqo yePolycarbon Power, engenako ukukopishwa ngezinye iinkampani. Ukuthandwa kweebhetri zegraphene kuya kuba yinto yokuxhuma kwizithuthi zombane. Emva kokuba iibhetri zegraphene zisetyenziswe kwizithuthi zombane, ziya kuba neenguqu eziphazamisayo kulo lonke ishishini leemoto.
‘S iteknoloji engundoqo
Imfihlakalo yetekhnoloji engundoqo kukwamkela ingqikelelo yoyilo lolungelelwaniso olubanzi lwentsebenzo, kwaye ngobuchule bazise izinto ezintsha zekhabhoni esekwe kwigraphene kwi-electrode elungileyo nengalunganga yebhetri ye-capacitor ukufezekisa indibaniselwano yee-supercapacitors eziqhelekileyo kunye neebhetri ezinamandla amakhulu, ngaloo ndlela udibanisa ukusebenza okugqwesileyo kwee-supercapacitors eziqhelekileyo kunye neebhetri ezidibeneyo.
ukusebenzisa
