Ngoku uhlaziyo lweenkqubo zefowuni eziphathwayo ziya zikhawuleza kwaye zikhawuleza, kwaye isantya sokutshaja sefowuni yeselula siya sikhula ngokukhawuleza nangokukhawuleza.Inokuhlawuliswa ngokupheleleyo kwiyure ukusuka kobunye ubusuku obudlulileyo.Namhlanje, iibhetri ezisetyenziswa kwii-smartphones ziibhetri ze-lithium.Nangona kusithiwa isantya sokutshaja sikhawuleza kuneebhetri zenickel zangaphambili, ayikakhawulezi njengesantya sokutshaja se-super capacitors, kwaye yonakala lula.I-supercapacitor ikhawuleza kuzo zombini ukutshaja kunye nokukhupha, kwaye inokuhlawuliswa ngokuphindaphindiweyo kwaye ikhutshwe ngamakhulu amawaka amaxesha ukuze isebenze ixesha elide.
Izizathu zokuba kutheniii-supercapacitorsbiza ngokukhawuleza:
1. I-Supercapacitors inokugcina ngokuthe ngqo iintlawulo ngaphandle kweekhemikhali zokuphendula ngexesha lenkqubo yokugcina amandla.Akukho nto i-impedance eyenziwa yi-electrochemical reactions, kwaye ukutshaja kunye nokukhupha isiphaluka kulula.Ke ngoko, ii-supercapacitors zitshaja ngokukhawuleza, zinoxinzelelo oluphezulu lwamandla kuneebhetri kunye nokulahleka kwamandla okuncinci.
2. Izinto zekhabhoni ezisetyenziswa kwi-supercapacitor zonyusa ummandla othile wesakhiwo, indawo ethile yendawo iyanda, kwaye intlawulo ye-adsorbed kwindawo ephezulu iyanda, ngaloo ndlela yandisa amandla okugcina amandla e-supercapacitor, kunye ne-porous. I-carbon material nayo ine-conductivity egqwesileyo, eyenza ukuhanjiswa kwentlawulo kube lula.
Yingakho i-supercapacitor ihlawulisa ngokukhawuleza kangangokuba inokufikelela ngaphezu kwe-95% ye-capacitance yayo elinganisiweyo kwimizuzwana eyi-10 ukuya kwimizuzu eyi-10.Ngaphezu koko, i-crystal structure ye-electrode ye-supercapacitor ayiyi kutshintsha ngenxa yokutshaja kunye nokukhupha, kwaye inokuphinda isetyenziswe ixesha elide.
Ngenxa yothintelo oluthile lwee-supercapacitors, azinakuthatha indawo yeebhetri ze-lithium okwangoku.Nangona kunjalo, ndiyakholelwa ukuba ingxaki ye-supercapacitor encinci iya kuphulwa kwixesha elizayo, masijonge phambili kunye.
