Iimfuno ezintathu eziphambili zebhetri yokugcina amandla, ukhuseleko lolona lubalulekileyo
Ukugcinwa kwamandla e-electrochemical kuthathwa njengendlela ephambili yokugcina amandla kwinkqubo yamandla ezayo, ibhetri kunye ne-PCS lixabiso eliphezulu kunye nezithintelo kwi-chain chain chain, imfuno ephambili ilele kukhuseleko oluphezulu, ubomi obude kunye neendleko eziphantsi. Phakathi kwazo, ukhuseleko lungundoqo. Ezinye iingcali zemizi-mveliso zathi, ngoku indawo yokugcina amandla e-electrochemical ikhula ngokukhawuleza, kodwa umba wokhuseleko yingxaki yophuhliso lwawo olukhulu, indawo yokugcina amandla eBeijing kunye neprojekthi yogcino lwamandla eTesla Australia yoqhushumbo nakwishishini lokugcina amandla liye lakhala i-alarm.
Ukuza kuthi ga ngoku, iimbono eziKhokelelwayo zokuKhawulezisa uPhuhliso lweSitorethi saMandla amatsha zibeka phambili ukusekwa kwemigangatho yeteknoloji yokhuseleko kunye nenkqubo yokulawula, ukomeleza ulawulo lokhuseleko lomlilo, ukuthobela ngokungqongqo umgca osezantsi wokhuseleko njengomgaqo osisiseko; kukhuseleko oluphezulu, ixabiso eliphantsi, ukuthembeka okuphezulu, ubomi obude kunye neminye imiba yenkqubela phambili; ukomeleza ukhuseleko lophando lweteknoloji yokugcina amandla e-electrochemical njalo njalo. IKhomishini yoPhuhliso lweSizwe kunye noHlaziyo, iBhodi yeSizwe yaMandla ukuququzelela ukuqulunqwa kwe "Imilinganiselo yeThutyana yoLawulo oluKhuselekileyo lwe-Electrochemical Energy Storage Stations (iDrafti)", nayo ibe ngo-Agasti 24 kuluntu ukuze kuboniswane noluntu, ukuqinisa ulawulo lokhuseleko lokugcinwa kwamandla.
Ukhuseleko oluphezulu, ubomi obude, ibhetri ye-nickel-metal hydride amanqaku aphezulu
Idatha ye-China Battery Industry Association ibonisa ukuba ukhuseleko oluphezulu lwe-nickel-metal hydride yombane, ubomi bomjikelo omde, i-electrode yayo eyenziwe ngee-nickel spheres, i-electrode negative esebenzayo ixhaswa yi-hydrogen yokugcina i-alloy, yeyemathiriyeli ezinzileyo, i-electrolyte yamanzi ineempawu ezintle zokubuyiswa komlilo, ayiyi kuqhuma kwaye itshise iingozi ze-140 zebhethri; ubomi bomjikelezo ukuya kuthi ga kwi-3,000, ukutshaja okunzulu kunye nokukhupha umjikelo welizwe ukuya kumaxesha angama-10,000 nangaphezulu; ingasetyenziselwa amaxesha angaphezu kwe-10,000; ingasetyenziselwa amaxesha angaphezu kwe-10,000. Ngamaxesha angaphezu kwe-10,000; inokugcina izinga eliphezulu lokutshaja kunye nokukhupha kwi -40°C ~ 60°C okusingqongileyo. I-Toyota HEV imoto yokuthengiswa kwemoto yehlabathi ifikelele ngaphezu kwe-18 yezigidi, kwaye ixhotyiswe ngokubanzi ngeebhetri ze-nickel-metal hydride, akuzange kubekho nanye imeko yeengozi zokutsha kwebhetri, ukhuseleko oluphezulu lwebhetri luqinisekisiwe ngokupheleleyo.
Ngaphezu koko, ukutshaja ibhetri kunye nokukhutshwa kukuguqulwa kwamandla ekhemikhali kunye namandla ombane, ubushushu bunempembelelo enkulu kwi-chemical reaction. Izikhululo zamandla okugcina amandla ubukhulu becala zingaphandle, uninzi lweentlobo zeebhetri zichaphazeleka kokusingqongileyo kunye nobushushu, ukukhawulela indawo yezikhululo zamandla kunye nokwenza buthathaka indima yokugcina amandla. Iibhetri ze-nickel-metal hydride kubushushu obuphantsi kakhulu kunye nobushushu obuphezulu bentlawulo egqwesileyo kunye nokukhupha ukusebenza kakuhle, ukuze indawo yokugcina amandla kwisikhululo samandla ibe bhetyebhetye ngakumbi, ilula, isebenze ngcono ngokubanzi, ethe yaba kukuthatha inxaxheba kwayo kukhuphiswano lweendlela ezahlukeneyo zobuchwepheshe bebhetri "kunye namanqaku".
Ngapha koko, iibhetri ze-nickel-metal hydride kwisicelo semarike yokugcina amandla ibe ngumzekelo. Ngo-2020, inkampani yokugcina amandla ebhetri ye-nickel-metal hydride iNilar yiBhanki yoTyalo-mali yaseYurophu i-47 yezigidi zee-euro zotyalo-mali. Kuyaqondwa ukuba i-Nilar igxininise ekudibaniseni ukuveliswa kwamandla okuvuselela kunye nokugcinwa, amandla okulinda kunye nezicelo zokutshaja izithuthi zombane, utyalo-mali kukukhuthaza inkampani iya kuhlanganiswa kwibhetri yendawo yokuhlala, yorhwebo kunye nezoshishino kunye negridi-scale okanye iinkqubo zemarike yeziseko. Ngokutsho kweFrontiers kwiSayensi yePolymer, iqela likaNjingalwazi uYi Cui kwiYunivesithi yaseStanford liye laphuhlisa ibhetri ye-nickel-metal hydride (Ni-MH) yebhetri enkulu yokuvuselela amandla kunye nokugcinwa kwezicelo, kunye neenzuzo zobomi benkonzo ye-ultra-long, akukho mngcipheko womlilo okanye ukutshatyalaliswa kwe-thermal, akukho mfuneko yokugcinwa kwesiqhelo, ukuziphatha kakuhle kwexabiso eliphantsi, kunye nokuziphatha okuhle kwexabiso eliphantsi. Iqela likaCui liya kwakha iyunithi yokulinga kunye nomthamo wokugcina we-2 megawatts ngo-2021, kwaye iceba ukwandisa umthamo wayo ukuya kuma-20 ngokuphindwe kabini loo mali ngo-2022.
