ʻAʻole makaʻu ʻo Supercapacitor i ka wela haʻahaʻa

Ma muli o ka wikiwiki o ka hoʻouka ʻana a me ka hoʻololi kiʻekiʻe o ka ikehu,nā capacitors nuihiki ke hana hou ʻia i nā haneli haneli mau manawa a lōʻihi nā hola hana, i kēia manawa ua hoʻohana ʻia lākou i nā kaʻa kaʻa uila hou.Hiki i nā kaʻa ikehu hou e hoʻohana ana i nā supercapacitors e like me ka hoʻouka ʻana i ka ikehu hiki ke hoʻomaka i ka hoʻopaʻa ʻana i ka wā e piʻi ai ka poʻe kaʻa i ke kaʻa.Hiki i hoʻokahi minuke o ka hoʻopaʻa ʻana ke ʻae i nā kaʻa ikaika hou e holo no 10-15 mau kilomita.ʻOi aku ka maikaʻi o ia mau supercapacitors ma mua o nā pihi.ʻOi aku ka lohi o ka hoʻouka ʻana o nā pākaukau ma mua o ka super capacitors.He hapalua hola wale nō e hoʻouka ai i ka 70% -80% o ka mana. Eia naʻe, ma nā wahi wela haʻahaʻa, hoʻemi nui ʻia ka hana o nā supercapacitors.ʻO kēia no ka mea ua keakea ʻia ka diffusion o nā ion electrolyte i nā haʻahaʻa haʻahaʻa, a ʻo ka hana electrochemical o nā mea mālama mana e like me nā supercapacitors e hoʻemi koke ʻia, e hopena i ka hoʻemi nui ʻana o ka hana hana o nā supercapacitors i nā wahi wela haʻahaʻa.No laila aia kekahi ala e hoʻomau ai ka supercapacitor i ka hana like ʻana ma kahi ʻano wela haʻahaʻa? ʻAe, photothermal-hoʻonui supercapacitors, supercapacitors noiʻi e ka hui o Wang Zhenyang Research Institute, Institute of Solid State Research, Hefei Research Institute, Chinese Academy o Sciences.I ka haʻahaʻa haʻahaʻa haʻahaʻa, ka electrochemical hana o supercapacitors ua attenuated nui, a me ka hoʻohana 'ana i ka electrode mea me ka photothermal waiwai hiki ke hoʻokō koke wela wela o ka mea ma o ka lā photothermal hopena, ka mea i manaoia e hoʻomaikaʻi i ka haʻahaʻa wela hana o supercapacitors. Ua hoʻohana nā mea noiʻi i ka ʻenehana laser no ka hoʻomākaukau ʻana i kahi kiʻi aniani graphene me kahi ʻano porous ʻekolu-dimensional, a hoʻohui i ka polypyrrole a me ka graphene ma o ka ʻenehana electrodeposition pulsed e hana i kahi electrode composite graphene/polypyrrole.ʻO ia electrode kahi mana kikoʻī kiʻekiʻe a hoʻohana i ka ikehu lā.Hoʻomaopopo ka hopena photothermal i ka piʻi wikiwiki o ka mahana electrode a me nā ʻano ʻē aʻe.Ma kēia kumu, ua kūkulu hou nā mea noiʻi i kahi ʻano hou o ka supercapacitor i hoʻonui ʻia i ka photothermally, ʻaʻole hiki ke hōʻike wale i ka mea electrode i ka lā, akā e pale pono i ka electrolyte paʻa.Ma kahi haʻahaʻa haʻahaʻa haʻahaʻa o -30 °C, hiki ke hoʻomaikaʻi wikiwiki ʻia ka hana electrochemical o nā supercapacitors me ka pohō nui i ka pae wela o ka lumi ma lalo o ka hoʻomālamalama ʻana o ka lā.I loko o kahi lumi wela (15 ° C), piʻi ka mahana o ka supercapacitor e 45 ° C ma lalo o ka lā.Ma hope o ka piʻi ʻana o ka mahana, e hoʻonui nui ʻia ka hoʻolālā electrode pore a me ka helu diffusion electrolyte, kahi e hoʻomaikaʻi nui ai i ka hiki ke mālama uila o ka capacitor.Eia kekahi, no ka mea ua pale maikaʻi ʻia ka electrolyte paʻa, ʻoi aku ka kiʻekiʻe o ka capacitance retention rate o ka capacitor e like me 85.8% ma hope o 10,000 mau uku a me nā hoʻokuʻu. ʻO nā hualoaʻa noiʻi o ka hui noiʻi a Wang Zhenyang ma ka Hefei Research Institute o ka Chinese Academy of Sciences ua hoʻokipa ʻia a kākoʻo ʻia e nā papahana R&D koʻikoʻi a me ka Natural Science Foundation.Manaʻolana mākou e ʻike a hoʻohana i nā supercapacitors i hoʻonui ʻia i ka photothermally i ka wā e hiki mai ana.
