ʻO ka Capacitor kahi mea e mālama ai i ka uku uila.ʻO ke kumu o ka mālama ʻana i ka ikehu o ka capacitor maʻamau a me ka ultra capacitor (EDLC) he like ia, ʻo nā hale kūʻai ʻelua ma ke ʻano o ke kahua electrostatic, akā ʻoi aku ka maikaʻi o ka super capacitor no ka hoʻokuʻu wikiwiki ʻana a me ka mālama ʻana i ka ikehu, ʻoi aku hoʻi no ka hoʻomalu ʻana i ka ikehu pololei a me nā mea hoʻouka koke. .
E kūkākūkā kākou i nā ʻokoʻa nui ma waena o nā capacitors maʻamau a me nā capacitors super ma lalo nei.
| Nā mea hoʻohālikelike | Kahiko maʻamau | Supercapacitor |
| Nānā nui | ʻO ka capacitor maʻamau kahi dielectric mālama mālama paʻa, hiki ke loaʻa ka uku mau a hoʻohana nui ʻia.He mea ia e pono ai ka uila uila ma ke kahua o ka mana uila. | ʻO Supercapacitor, i ʻike ʻia he capacitor electrochemical, capacitor papa pālua, capacitor gula, Faraday capacitor, he mea electrochemical i hoʻomohala ʻia mai nā 1970s a me 1980s e mālama i ka ikehu ma o ka polarizing i ka electrolyte. |
| Kūkulu | ʻO ka capacitor maʻamau he ʻelua mea hoʻokele metala (electrodes) i pili like i ka like akā ʻaʻole i pili, me kahi dielectric insulating ma waena. | ʻO kahi supercapacitor he electrode, he electrolyte (loaʻa ka paʻakai electrolyte), a me kahi mea hoʻokaʻawale (pale i ka pilina ma waena o nā electrodes maikaʻi a maikaʻi ʻole). Hoʻopili ʻia nā electrodes me ka carbon activated, nona nā pores liʻiliʻi ma kona ʻili e hoʻonui i ka ʻili o nā electrodes a mālama i ka uila. |
| Nā mea dielectric | Hoʻohana ʻia ka alumini oxide, nā kiʻiʻoniʻoni polymer a i ʻole nā ceramics e like me ka dielectrics ma waena o nā electrodes i nā capacitors. | ʻAʻohe dielectric kahi supercapacitor.Akā, hoʻohana ʻo ia i kahi papa pālua uila i hana ʻia e kahi paʻa (electrode) a me kahi wai (electrolyte) ma ke kikowaena ma kahi o kahi dielectric. |
| Kumu o ka hana | ʻO ke kumu hana o ka capacitor e hoʻoneʻe ʻia ka uku e ka ikaika i loko o ke kahua uila, ke loaʻa kahi dielectric ma waena o nā conductors, ke keʻakeʻa nei ia i ka neʻe ʻana o ka hoʻopiʻi a hoʻonui ʻia ka uku ma luna o ka conductor, e hopena i ka hōʻiliʻili ʻana o ka mālama mālama. . | ʻO nā supercapacitors, ma ka ʻaoʻao ʻē aʻe, e hoʻokō i ka mālama ʻana i ka ikehu pālua pālua ma ka polarizing i ka electrolyte a me ka redox pseudo-capacitive charges. Hiki ke hoʻololi hou ʻia ke kaʻina hana mālama ikehu o nā supercapacitors me ka ʻole o nā hopena kemika, a no laila hiki ke hoʻopiʻi pinepine ʻia a hoʻokuʻu ʻia i nā haneli haneli mau manawa. |
| Ka manaʻo | ʻOi aku ka liʻiliʻi. ʻO ka mana capacitance maʻamau mai kahi mau pF a i kekahi mau tausani μF. | Nui ka mana. Nui ka mana o ka supercapacitor a hiki ke hoʻohana ʻia ma ke ʻano he pākaukau.ʻO ka mana o ka supercapacitor e pili ana i ka mamao ma waena o nā electrodes a me ka ʻili o nā electrodes.No laila, ua uhi ʻia nā electrodes me ka carbon activated e hoʻonui i ka ʻili o ka ʻili e hiki ai ke kiʻekiʻe. |
| Paʻa ikehu | Haʻahaʻa | Kiʻekiʻe |
| ikehu kiko | <0.1 Wh/kg | 1-10 Wh/kg |
| Mana kikoʻī | 100,000+ Wh/kg | 10,000+ Wh/kg |
| Ka manawa hoʻouka / hoʻokuʻu | ʻO ka manawa hoʻouka a me ka hoʻokuʻu ʻana o nā capacitors maʻamau he 103-106 kekona. | Hiki i nā Ultracapacitors ke hāʻawi i ka hoʻopiʻi ʻoi aku ka wikiwiki ma mua o nā pākaukau, e like me ka wikiwiki o 10 kekona, a mālama i ka nui o ka uku no kēlā me kēia ʻāpana ma mua o nā capacitors maʻamau.ʻO ia ke kumu e noʻonoʻo ʻia ai ma waena o nā pākaukau a me nā capacitors electrolytic. |
| ʻO ke ola pōʻaiapili hoʻopaʻa / hoʻokuʻu | Pōkole | ʻOi aku ka lōʻihi (maʻa mau 100,000 +, a hiki i 1 miliona mau pōʻai, ʻoi aku ma mua o 10 mau makahiki o ka noi) |
| ʻO ka maikaʻi o ka hoʻouka / hoʻokuʻu ʻana | >95% | 85%-98% |
| Hana wela | -20 a 70 ℃ | -40 a 70 ℃ (ʻOi aku ka maikaʻi o nā ʻano wela haʻahaʻa haʻahaʻa a ʻoi aku ka laulā o ka wela) |
| Volta koho | Kiʻekiʻe | lalo (maʻamau 2.5V) |
| Koina | lalo | Kiʻekiʻe |
| Pōmaikaʻi | Liʻiliʻi ka poho Kiʻekiʻe hoʻohui pū Ka mana hoʻoikaika a me ka mana | Ola lōʻihi Hiki ke kiʻekiʻe loa Hoʻouka wikiwiki a me ka manawa hoʻokuʻu Keia haawe kiʻekiʻe ʻOi aku ka laulā o ka wela hana |
| Palapala noi | ▶ Hoʻopuka i ka mana maʻemaʻe; ▶Power Factor Correction (PFC); ▶ Nā kānana alapine, nā kānana kiʻekiʻe, nā kānana haʻahaʻa; ▶ Hoʻohui a me ka wehe ʻana i ka hōʻailona; ▶ Nā mea hoʻomaka kaʻa; ▶ Buffers (nā mea pale a me nā kānana kani); ▶Oscillators. | ▶Nā kaʻa ikehu hou, nā alahao a me nā mea hoʻohana ʻē aʻe; ▶Uninterruptible power supply (UPS), hoʻololi i nā waihona capacitor electrolytic; ▶Ka lako mana no nā kelepona paʻa lima, nā kamepiula lawe lima, a pēlā aku; ▶ ʻO nā screwdrivers uila hiki ke hoʻopiha piha ʻia i nā minuke; ▶ ʻO nā ʻōnaehana kukui ulia pōpilikia a me nā mea uila uila mana kiʻekiʻe; ▶ICs, RAM, CMOS, uaki a me nā microcomputers, etc. |
