Ibhetri ye-lipo eguquguqukayo

Oku kufunyaniswe kwenza abanye abaphandi bavelise iintlobo ezintsha zeebhetri ze-Li-ion eziguquguqukayo ezisebenzisa izinto ezingekho mgangathweni ezifana neepolymer elastic kunye nolwelo lwendalo endaweni ye-electrolytes elulwelo olunokutsha (into evumela i-ion ukuba ihambe phakathi kwee-electrode ezimbini) .Iinkampani ezininzi ziye zavelisa iimveliso ezisekelwe kwezi zixhobo zitsha, kwaye eli nqaku liza kuphonononga iintlobo ezimbini zeebhetri eziguqukayo ezifumanekayo ngoku ezisetyenziselwa urhwebo.

Uhlobo lokuqala lusebenzisa i-electrolyte esemgangathweni kodwa kunye ne-polymer composite separator endaweni ye-porous polyethylene eqhelekileyo okanye i-polypropylene. Oku kuvumela ukuba igobe okanye ibunjwe kwiifom ezahlukeneyo ngaphandle kokuqhekeka. Umzekelo, i-Samsung isandula ukubhengeza ukuba baphuhlise ibhetri enokuthi igcine imilo yayo nokuba isongelwe phakathi. Ezi bhetri zibiza kakhulu kunezo zemveli kodwa zingahlala ixesha elide kuba kukho ukuxhathisa okuncinci kwangaphakathi kwii-electrode ezityebileyo kunye nezahluli. Nangona kunjalo, enye into ebuyayo kukuxinana kwamandla aphantsi: Banokugcina kuphela amandla amaninzi njengebhetri yeLi-ion enobungakanani obufanayo kwaye abanakutshajwa kwakhona ngokukhawuleza.

Olu hlobo lwebhetri ye-Li-ion okwangoku lusetyenziswa kwiiSensors eziNxitywayo ukujonga iimpawu ezibalulekileyo zomzimba, kodwa inokudityaniswa nempahla ekrelekrele. Umzekelo, iCute Circuit yenza ilokhwe elandelela amanqanaba ongcoliseko lomoya kwaye ilumkise abasebenzisi ngesiboniso se-LED ngasemva xa kukho amanqanaba aphezulu kwindawo ekufutshane yomntu oyinxibileyo. Ukusebenzisa olu hlobo lwebhetri eguquguqukayo kuya kwenza kube lula ukudibanisa izinzwa ngokuthe ngqo kwiimpahla ngaphandle kokongeza isambuku okanye ukungakhululeki.

Iibhetri zeLithium zisetyenziswa kakhulu kwiimveliso zabathengi ezifana neeselfowuni kunye neelaptops, kodwa ukuphuculwa kwezakhono zayo (amandla, ubunzima) kunokukhokelela kwizicelo ezinenzuzo ezifana nezixhobo zonyango kunye neemoto zombane. Ekubeni iibhetri ezininzi zisebenzisa i-casing eqinile kunye nee-electrode ezibekwe ngaphakathi, kukho uphando olubanzi malunga nokuba ibhetri eguquguqukayo inokuphuhliswa enokuthi ivumele iimilo ezahlukeneyo kunye nezixhobo ezinokuba namandla ngakumbi.

Izithuthi zombane ezikhoyo ngoku zinoluhlu olulinganiselweyo ngenxa yoxinano lwamandla asezantsi eebhetri eziphuma ekusebenziseni iikhaseji eziqinileyo. Iibhetri eziguquguqukayo zinokunxitywa kwimpahla okanye zijikelezwe kwindawo engaqhelekanga, nto leyo evula amathuba amatsha kubuchwepheshe obunxitywayo. Ukongeza, ukuguquguquka okukhulu kuthetha ukuba iibhetri zinokugcinwa kwiindawo ezixineneyo kwaye zihambelane neemilo ezingaqhelekanga; oku kunokubangela iibhetri ezinobungakanani obuncinci kunezo zilinganiswe ngokufanayo eziqhelekileyo.

iziphumo:

Ibhetri ebhetyebhetye esebenzisa ifoyile yentsimbi endaweni yeeelectrode eziqinileyo iye yaphuhliswa ngabaphandi beYunivesithi yaseCalifornia, eBerkeley. Uyilo lunesithembiso sentsebenzo engcono kunezixhobo zangoku ngenxa yokuba luqulunqwe ngamashiti abhityileyo amaninzi apakishwe kunye, nto leyo ekhokelela kuxinano lwamandla ngelixa ehlala ebhetyebhetye ngokupheleleyo. Iinzame zangaphambili zokusebenzisa ezinye izinto ezifana negraphene aziphumelelanga ngenxa yobuthathaka bezi zakhiwo kunye nokunqongophala kobunzima. Nangona kunjalo, uyilo olutsha lwe-foil yensimbi lulandela isakhiwo esifanayo kwiibhetri ze-lithium-ion zorhwebo kwaye zivumela ezi yunithi ukuba ziveliswe kwinqanaba lezoshishino ngaphandle kobunzima.

lwezicelo:

Iibhetri ze-lipo eziguquguqukayo zingakhokelela kwizixhobo zonyango ezigqithwa ngokulula ngakumbi emzimbeni, iimoto zombane ezinoluhlu olukhulu lokuqhuba, iteknoloji enxibekayo engaphazamisi ukuhamba, kunye nezinye izicelo ezithatha inzuzo yokunyuka kokuguquguquka.

Isiphelo:

Uphando kwiYunivesithi yaseCalifornia Berkeley luvelise ibhetri eguquguqukayo eyenziwe ngamacwecwe esinyithi apakishwe ngaphandle kokusebenzisa imathiriyeli yegraphene ebuthathaka. Olu luyilo lubonelela ngoxinzelelo lwamandla olwandisiweyo kunezixhobo zangoku ngelixa lihlala libhetyebhetye ngokupheleleyo. Iibhetri ze-lipo eziguquguqukayo nazo zinezicelo ezinokubakho kwiimoto zombane, itekhnoloji enxibekayo, kunye nezinye iindawo apho ukonyuka kokuguquguquka kunenzuzo.
