Ma Kina, ua hoʻohana ʻia nā supercapacitors i nā kaʻa uila no nā makahiki he nui.No laila he aha nā pōmaikaʻi o nā supercapacitors i nā kaʻa uila?No ke aha he super capacitors?
ʻO nā capacitors nui
super capacitor, kaʻa uila, pākahi lithium
Ua pilikia mau nā mea nona nā kaʻa uila i ka holo ʻana, a i kēlā me kēia lā hoʻomaha e hoʻopiʻi ʻia.E nānā mua kākou i ke kumu o ka hopohopo holo moana:
He 13,000 Wh/kg ka nui o ka ikehu ikehu o ka aila no na ka'a ma'amau.I kēia manawa, ʻo 200-300Wh/kg ka nui o ka ikehu o nā pā lithium mainstream.Eia nō naʻe, ʻoi aku ka maikaʻi o ka hoʻololi ʻana i ka ikehu o nā kaʻa uila maʻemaʻe he 2-3 mau manawa kiʻekiʻe ma mua o nā locomotives diesel.No laila, i mea e hoʻohana ai i ka ikehu me ka ʻoi aku ka maikaʻi, ʻo ke ala maikaʻi loa ka hoʻonui ʻana i ka ikehu o nā pā lithium.
ʻOiai ua hoʻonui ʻia ka nui o ka ikehu i 10 mau manawa i loko o ka hale hana, e uku hou ʻia ka pākaukau ma hope o nā helu he nui a me nā hoʻokuʻu.
No laila hiki paha ke hoʻonui i ka nui o ka ikehu i kahi pae haʻahaʻa a mālama mau i ka helu kūpono o ka uku a me ka hoʻokuʻu?
Nā mea hoʻopaʻa kiʻekiʻe
ʻO ka Capacitor kekahi o nā mea uila maʻamau.I ka pōkole, ʻelua ʻāpana o nā ʻāpana metala sanwiti i kahi ʻāpana insulating, a hoʻohui ʻia kahi pūpū pale ma waho.Aia ma waena o kēia mau pepa ʻelua ka wahi e mālama ʻia ai ka ikehu uila.Hoʻohana ʻia ka capacitor ma ke ʻano he mana hikiwawe, no laila ʻaʻole nui ka ikehu uila i mālama ʻia, a ʻoi aku ka ʻino o ka ikehu ma mua o ka pākaukau.
Akā, he mea maika'i ka capacitor i loa'a'ole i ka pila: he lō'ihi loa ke ola a me ka ho'oku'u 'ana - 'o ia ho'i he mau haneli haneli o ka ho'opi'i a me ka ho'oku'u 'ana, he mea li'ili'i loa ka ho'oha'aha'a hana.No laila ua like kona ola me ka huahana pono'ī.
ʻO ke kumu i loaʻa ai ka uku maikaʻi loa a me ka hoʻokuʻu ʻana i ke ola no ka mea ʻo ka mālama ʻana i ka ikehu capacitor e pili ana i nā kumu kino a ʻaʻole i hana i nā hopena kemika.
No laila ʻo ka hana e hoʻonui i ka hiki ke mālama i ka ikehu uila o ka capacitor.No laila, ʻike ʻia ka supercapacitor.ʻO ke kumu o ka hoʻolilo ʻana i ka capacitor i waihona, ʻaʻole i kahi lako mana koke.Akā ʻo ka paʻakikī nui loa pehea e hoʻomaikaʻi ai i ka ikehu o nā supercapacitors.
Hiki ke hoʻohana ʻia ka supercapacitor i kumu mana no nā kaʻa uila ma hope o ka hoʻonui ʻana i ka ikehu.Ua hoʻomaka mua ʻo Kina e hoʻohana i kēia ʻenehana.Ma ka 2010 Shanghai World Expo, ua hōʻike ʻia he 36 mau kaʻa super capacitor.Ua paʻa kēia mau kaʻa kaʻa no ka manawa lōʻihi a ke hana mau nei a hiki i kēia manawa.
Hiki i nā kaʻa kaʻa supercapacitor ma Shanghai ke holo i 40 mau kilomita i 7 mau minuke
Akā ʻaʻole i laha ka ʻenehana i nā ala ʻē aʻe a me nā kūlanakauhale ʻē aʻe.ʻO kēia hoʻi kahi pilikia "cruising range" ma muli o ka haʻahaʻa haʻahaʻa o ka ikehu.ʻOiai ua pōkole loa ka manawa e hoʻopaʻa ai, he mau minuke wale nō ia e hoʻopaʻa ai i hoʻokahi manawa, akā hiki ke lōʻihi ma kahi o 40 mau kilomita.I ka hoʻohana mua ʻana, pono e hoʻopiha hou ʻia ke kaʻa i kēlā me kēia manawa e kū ai.
ʻAʻole maikaʻi ka ikaika o ka ikehu o kēia mau supercapacitors e like me nā pā lithium.ʻO ke kumu nui loa, ʻaʻole lawa ka kiʻekiʻe o ka dielectric mau o nā mea i hoʻokumu ʻia i ke kalapona i nā supercapacitors.Ma ka ʻatikala aʻe, e kamaʻilio mākou e pili ana i ka holomua o Kina i ka hoʻomaikaʻi ʻana i ka ikehu o nā supercapacitors.
ʻO JYH HSU(JEC)) kahi mea hana supercapacitor Kina i loea i ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana a me ke kūʻai ʻana i nā ʻāpana uila like ʻole.Inā he mau nīnau kāu e pili ana i nā ʻāpana uila a makemake paha e ʻimi i ka hui ʻoihana, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou i kēlā me kēia manawa.
