A kasar Sin, an shafe shekaru da yawa ana amfani da na'urori masu karfin wuta a cikin motocin lantarki.Don haka menene fa'idodin supercapacitors a cikin motocin lantarki?Me yasa super capacitors suke da girma sosai?
Super capacitors
super capacitor, lantarki abin hawa, lithium baturi
Masu motocin lantarki koyaushe suna cikin damuwa ta hanyar zirga-zirgar jiragen ruwa, kuma kowane hutu za a sami gunaguni.Bari mu fara duba tushen damuwa na tafiye-tafiye:
Matsakaicin yawan kuzarin mai na motocin al'ada shine 13,000 Wh/kg.A halin yanzu, ƙarfin ƙarfin baturan lithium na yau da kullun shine 200-300Wh/kg.Duk da haka, ingancin canjin makamashi na motocin lantarki masu tsabta ya ninka sau 2-3 fiye da na locomotives na diesel.Don haka, don amfani da makamashi tare da mafi girman inganci, hanya mafi kyau ita ce ƙara ƙarfin ƙarfin ƙarfin baturan lithium.
Kodayake an ƙara yawan kuzari zuwa sau 10 a cikin dakin gwaje-gwaje, ana mayar da batirin bayan an yi caji da yawa.
Don haka yana yiwuwa a ƙara yawan ƙarfin makamashi zuwa matsakaicin matsayi kuma har yanzu kula da adadin da ya dace na caji da fitarwa?
Super capacitors
Capacitor yana ɗaya daga cikin mahimman abubuwan haɗin lantarki.A takaice, yadudduka biyu na bangon ƙarfe suna yin sandwich ɗin da aka rufe, kuma ana ƙara harsashi mai kariya a waje.Tsakanin waɗannan foils guda biyu akwai sararin da ake adana makamashin lantarki.Ana amfani da capacitor azaman samar da wutar lantarki nan take, don haka makamashin lantarki da aka adana ba shi da yawa, kuma yawan kuzarin ya fi baturi muni.
Amma capacitor yana da fa'ida wanda baturin ba shi da shi: cajin da rayuwa yana da tsayi sosai - har ma da daruruwan dubban lokuta na caji da fitarwa, lalacewar aikin yana da ƙananan.Don haka rayuwarsa iri ɗaya ce da samfurin kanta.
Dalilin da ya sa yana da irin wannan kyakkyawan caji da rayuwar fitarwa shine saboda ajiyar makamashi na capacitor ya dogara ne akan ka'idodin jiki kuma baya haifar da halayen sinadaran.
Don haka yanzu aikin shine faɗaɗa ƙarfin ajiyar makamashin lantarki na capacitor.Don haka supercapacitor ya bayyana.Manufar ita ce sanya capacitor ta zama tafki, ba kawai samar da wutar lantarki ba.Amma babbar matsala ita ce yadda za a inganta yawan makamashi na supercapacitors.
Ana iya amfani da supercapacitor azaman tushen wutar lantarki don motocin lantarki bayan haɓaka yawan kuzari.Tuni kasar Sin ta fara amfani da wannan fasaha.A 2010 Shanghai World Expo, 36 super capacitor bas aka baje.Waɗannan motocin bas ɗin sun daɗe suna aiki tuƙuru kuma har yanzu suna aiki kamar yadda aka saba har yanzu.
Motocin bas din masu karfin iya aiki a Shanghai na iya tafiyar kilomita 40 cikin mintuna 7
Amma fasahar ba ta yadu zuwa wasu hanyoyi da sauran garuruwa ba.Wannan kuma matsala ce ta "hanzari" da ƙarancin kuzari ya haifar.Ko da yake an rage lokacin caji sosai, yana ɗaukar mintuna kaɗan don cajin lokaci ɗaya, amma yana iya ɗaukar kusan kilomita 40 kawai.A farkon amfani, bas ɗin yana buƙatar caji duk lokacin da ta tsaya.
Yawan kuzarin waɗannan masu ƙarfin ƙarfin ba su da kyau kamar na batir lithium.Babban dalili shine cewa dielectric akai-akai na kayan tushen carbon a cikin manyan capacitors har yanzu bai isa ba.A cikin labarin na gaba, za mu yi magana kan ci gaban da kasar Sin ta samu wajen inganta yawan makamashin na'urori masu karfin iko.
JYH HSU (JEC)) wani kamfani ne na kasar Sin supercapacitor ƙware a cikin bincike da haɓakawa, samarwa da tallace-tallace na kayan aikin lantarki daban-daban.Idan kuna da tambayoyi game da abubuwan haɗin lantarki ko kuna son neman haɗin gwiwar kasuwanci, zaku iya tuntuɓar mu a kowane lokaci.
