He wāhanga rokiroki pūngao ngā ultracapacitors me ngā pākahiko. Engari he tukanga ā-tinana te tukanga rokiroki pūngao supercapacitors, he tukanga tauhohenga matū te rokiroki pūngao pākahiko, he rerekētanga nui kei waenganui i a rāua.

He pai ake ngā āhuatanga mana o te supercapacitor i tō te pākahiko, ka taea te utu me te tuku tere me te iahiko nui. He teitei ake te kiato pūngao o te pākahiko i tō te supercapacitor, ā, he nui ake te pūngao e rongoatia ana e te pākahiko i raro i te rōrahi kotahi. Ko te Supercapacitor he rauemi hohe waro me te waro pango kawe me te rauemi pepa hiko whakauru here, e whakamahi ana i te electrolyte polarized hei mimiti i ngā katote pai me ngā katote kino i roto i te electrolyte, ka hanga he hanganga paparanga hiko takirua mō te rokiroki pūngao, ko te tukanga rokiroki pūngao kāore e puta he tauhohenga matū, nō reira he roa rawa te ora huringa, ko te wā utu me te tuku whānui neke atu i te 500,000 ngā wā, he iti ake te wā utu me te tuku pākahiko, ko ngā pākahiko waikawa-mata 500 ngā wā, ko ngā pākahiko lithium 1000-1500 ngā wā, kāore i te ōrite ngā momo wā utu me te tuku rerekē; Ka mahi ngā Ultracapacitors i ngā pāmahana whānui ake i ngā pākahiko --40 ki te 65 nekehanga.

He rerekē hoki te whakamahinga o ngā mea e rua, he iti te kaha o te pūngao nui, engari nā te pai o te huringa, te tiaki taiao, me te kaha nui, ka whakamahia whānuitia i roto i te tuku hiko tārua, te utu me te tukunga auau teitei, te putanga hiko teitei me ētahi atu wā, ā, he nui te kaha o te pākahiko, engari ko tōna ake kaupapa he whakawhāiti i tōna roanga ora, ā, ka puta he whara kore e taea te whakakore i te utu nui me te tukunga nui, ā, kāore e pai ki te taiao. Heoi, i te korenga o ngā wāhanga rokiroki hiko e kitea hei whakakapi i taua kaha nui, ko te ao o ngā pākahiko (ngā pākahiko lithium-ion) kei te heke mai mō te wā roa, ā, ka whakakapia te penehīni me ētahi atu wahie hei matua mō te kaha nekeneke o te waka.

Ko te whanaungatanga i waenganui i ngā mea e rua, ko ngā painga o te putanga mana-teitei o te supercapacitor me te kaha ki te whakaae i te utu me te tukunga o te iahiko teitei ka taea te whakakotahi me te kiato pūngao teitei o te pākahiko hei whakapai ake i te roa o te pākahiko me te penapena pūngao o ngā waka hiko.
