Izibani zasemgwaqweni zelanga seziyingxenye ebalulekile yengqalasizinda yesimanje yasemadolobheni, ehlinzeka ngesixazululo sokukhanyisa esivumelana nemvelo futhi esingabizi kakhulu.Lezi zibani zincike ezinhlotsheni ezahlukahlukene zamabhethri ukuze zigcine amandla athathwe amaphaneli elanga phakathi nosuku.
1. Izibani zasemgwaqweni zelanga ngokuvamile zisebenzisa amabhethri e-lithium iron phosphate:
Iyini ibhethri ye-lithium iron phosphate?
Ibhethri ye-lithium iron phosphate wuhlobo lwebhethri ye-lithium-ion esebenzisa i-lithium iron phosphate (LiFePO4) njenge-cathode material kanye ne-carbon njengento ye-anode.Amandla kagesi eseli elilodwa angu-3.2V, kanti amandla ogesi anqamule ukushaja aphakathi kuka-3.6V no-3.65V.Ngesikhathi sokushaja, ama-ion e-lithium aphuma ku-lithium iron phosphate futhi ahambe nge-electrolyte aye ku-anode, azishumeke ku-carbon material.Ngesikhathi esifanayo, ama-electron akhululwa ku-cathode futhi adlule kumjikelezo wangaphandle aye ku-anode ukuze alondoloze ibhalansi yokusabela kwamakhemikhali.Ngesikhathi sokukhishwa, ama-ion e-lithium asuka ku-anode aye ku-cathode ngokusebenzisa i-electrolyte, kuyilapho ama-electron asuka ku-anode aye ku-cathode ngokusebenzisa isifunda sangaphandle, enikeza amandla emhlabeni ongaphandle.
Ibhethri ye-lithium iron phosphate ihlanganisa izinzuzo eziningi: ukuminyana kwamandla aphezulu, usayizi ohlangene, ukushaja okusheshayo, ukuqina, nokuzinza okuhle.Nokho, futhi ibiza kakhulu phakathi kwawo wonke amabhethri.Ngokuvamile isekela amashaji omjikelezo ojulile angu-1500-2000 futhi ingahlala iminyaka engu-8-10 ngaphansi kokusetshenziswa okuvamile.Isebenza phakathi kwezinga lokushisa elibanzi elingu -40°C kuya ku-70°C.
2. Amabhethri e-Colloidal avame ukusetshenziswa kumalambu e-solar street:
Liyini ibhethri le-colloidal?
Ibhethri le-colloidal wuhlobo lwebhethri le-lead-acid lapho i-ejenti ye-gelling yengezwa ku-sulfuric acid, iguqule i-electrolyte ibe yisimo esifana nejeli.Lawa mabhethri, ane-electrolyte yawo egayiwe, abizwa ngokuthi amabhethri angama-colloidal.Ngokungafani namabhethri e-lead-acid evamile, amabhethri e-colloidal athuthuka phezu kwezakhiwo ze-electrochemical zesakhiwo sesisekelo se-electrolyte.
Amabhethri e-Colloidal awakhathaleki, anqoba izinkinga zokunakekela ezivamile ezihlobene namabhethri e-lead-acid.Isakhiwo sazo sangaphakathi sithatha indawo ye-electrolyte ye-sulfuric acid eyi-liquid ngenguqulo ye-gelled, ethuthukisa kakhulu ukugcinwa kwamandla, umthamo wokuphuma, ukusebenza kokuphepha, kanye nempilo yokuphila, ngezinye izikhathi ngisho namabhethri e-ternary e-lithium-ion asebenza kahle ngokwenani.Amabhethri e-Colloidal angasebenza phakathi kwebanga lokushisa elingu-40°C kuya ku-65°C, okuwenza afanelekele ukusetshenziswa ezindaweni ezibandayo.Ziyakwazi futhi ukumelana nokushaqeka futhi zingasetshenziswa ngokuphepha ngaphansi kwezimo ezihlukahlukene ezinzima.Impilo yabo yesevisi iphindwe kabili noma ngaphezulu uma iqhathaniswa namabhethri ajwayelekile e-lead-acid.
3. Amabhethri e-lithium-ion e-NMC avame ukusetshenziswa kumalambu e-solar street:
Amabhethri e-NMC e-lithium-ion anikeza izinzuzo eziningi: amandla athile aphezulu, usayizi ohlangene, nokushaja okusheshayo.Ngokuvamile zisekela amashaji omjikelezo ojulile angu-500-800, anesikhathi sokuphila esifana namabhethri e-colloidal.Izinga lokushisa labo lokusebenza lisuka ku-15°C kuya ku-45°C.Nokho, amabhethri e-lithium-ion e-NMC nawo anezihibe, kuhlanganise nokuzinza okuncane kwangaphakathi.Uma kukhiqizwa abakhiqizi abangafanelekile, kunengozi yokuqhuma ngesikhathi sokushajwa ngokweqile noma ezindaweni eziphakeme zokushisa.
4. Amabhethri aneasidi yomthofu avame ukusetshenziswa kumalambu asemgwaqweni welanga:
Amabhethri aneasidi yomthofu anama-electrode akhiwe ngomthofu ne-lead oxide, ene-electrolyte eyenziwe ngesisombululo se-sulfuric acid.Izinzuzo ezibalulekile zamabhethri e-lead-acid amandla kagesi azinzile kanye nezindleko eziphansi.Kodwa-ke, banamandla athile aphansi, okuholela kuvolumu enkulu uma kuqhathaniswa namanye amabhethri.Isikhathi sabo sokuphila sifushane, ngokuvamile sisekela amashaji omjikelezo ojulile angu-300-500, futhi adinga ukulungiswa njalo.Naphezu kwalezi zimo ezimbi, amabhethri e-lead-acid ahlala esetshenziswa kabanzi embonini yokukhanya komgwaqo welanga ngenxa yenzuzo yawo yezindleko.
Ukukhethwa kwebhethri yezibani zasemgwaqweni zelanga kuncike ezintweni ezifana nokusebenza kahle kwamandla, ubude bempilo, izidingo zokunakekela, kanye nezindleko.Uhlobo ngalunye lwebhethri lunezinzuzo zalo eziyingqayizivele, ukuhlinzeka ngezidingo nemibandela ehlukene, ukuqinisekisa ukuthi izibani zasemgwaqweni zelanga zihlala ziyisixazululo sokukhanyisa esithembekile nesimeme.
