Ngophuhliso olukhawulezayo uluntu, amafutha amandla lithium ibhetri ethu kananjalo olukhula ngokukhawuleza. Ngoko Uyalulandela ulwazi oluneenkcukacha amafutha-piston Lithium ibhetri? Okulandelayo, makhe Xiaobian kukhokelela wonke ukufunda okungakumbi ngalo ulwazi. Fuel amandla ebhetri yi isixhobo conversion amandla.
izixhobo zokugcina amandla Ngokungafaniyo ezifana lithium Lithium, pack ibhetri amafutha oluqhutywa inokujikwa ngqo amandla ombane ukusabela electrochemical. Kwelinye icala, ibhetri Lithium ion eso abekwa ityala ngenxa ixesha elide amandla ivenkile, kunye ukubhobhoza ukuqhuba isithuthi ngexesha zokuhamba. Ngoko ke, isithuthi ibhetri isithuthi ibhetri ixhomekeke izibaso kwisithuthi, oko kukuthi, iyafana idizili trail eqhelekileyo, ukuba obuninzi zingagcinwa hydrogen.
Ukongezelela hydrogen, kwamafutha eqhelekileyo kwakhona ziquka methanol, hydrogen, hydrocarbon, ne-carbon monoxide. Iioksidenti ngabona badla oksijini okanye nomoya. electrolytes oqhelekileyo phosphoric acid, potassium hayidroksayidi, carbonate etyhidiweyo, kunye inwebu ion exchange.
Fuel amandla ebhetri sisixhobo isizukulwana amandla esiguqula amandla eekhemikhali kwi amafutha kunye oxidant ibe amandla ombane. Ngokungafaniyo injini yemveli yokuvutha kwangaphakathi, amandla eekhemikhali kwi wamafutha ekhutshwa basabela electrochemical ngu yokutsha kodwa ukusabela electrochemical, ngempumelelo aphezulu kunye nemisi zero. Ngaphezu koko, amafutha imoto amandla ebhetri umntu pack battery encinane igcina eseleyo amandla ombane ukusuka amafutha amandla ebhetri kwaye amandla nxeba aziqhekeza emotweni, kunye nezinto umbane emotweni kunye amafutha lamandla ebhetri xa kuyimfuneko.
Ngoko ke, amafutha amandla lithium ibhetri zinezibonelelo e umgama omde kuthelekiswa ibhetri Lithium ion. Isizukulwana amandla ebhetri amandla yamafutha umda Carno loop. Ngethiyori, ukwanela isizukulwana amandla unako ukufikelela 85% kwi-90%, kodwa ngenxa yokuba imida nokwehlukana ezahlukeneyo msebenzi, ukusebenza yangoku conversion amandla yeseli amandla fuel malunga-40% ukuya kuma-60%.
Ukuba amandla yombane ifunyanwa, iyonke izinga ukusetyenziswa kwamafutha nga kuma-80%. Ngenxa eliphezulu-iqhosha ukukhululwa Toyota Fuel Power Battery Mirai ngo-2014, ishishini ibhetri amandla kwamafutha ehlabathini bangena kwixesha elitsha. titanium Toyota kaThixo ingxubevange esityeni vuvabyi kwandisa lexinene amandla amafutha amandla ebhetri ntshunxekile ku-3.
1kW / L, kwaye iya kufikelela 4.0kw / L. Higher amandla ezinoxinano yenza le mfumba ezincinane, compact ngakumbi lula ukufaka.
Nangona kunjalo, lo corrosivity ye kwipleyiti yesinyithi kwenza izinto eziphezulu kunye neendleko zonyango komhlaba. Nakuba kunjalo, njengoko lo nokwanda kunye neziphumo nexabiso zobuchwepheshe, ipleyiti yesinyithi vuvabyi uba unciphiso enkulu emajukujukwini iindleko. Fuel technology amandla ebhetri yeyona ndlela ubugcisa lwangaphakathi yokutsha injini, emele ulwalathiso kuphuhliso lwexesha elizayo iimoto.
Noko ke, ukuba ucinga ezinye izithintelo kuphuhliso iibhetri lwamandla amafutha, uya kufumanisa ukuba iibhetri amandla amafutha zilungiselelwa ngoku ukuba inzuzo kwixesha elizayo. Nentekelelo abanethemba kukuba yemveliso yorhwebo leminyaka ubuncinane 15 ziya kusetyenziswa isithuthi amafutha amandla ebhetri usebenzisa hydrogen nyulu nje isibaso. Nokuba uyaqonda iqondo elithile loshishino, kuya kuba imali eninzi.
Xa ibhetri amandla yamafutha isetyenziswa njenge amafutha nje amafutha, lokukhutshwa icarbon dioxide ziye zancitshiswa ngaphezu kwe-40% xa kuthelekiswa inkqubo injini thermal, nto leyo ibaluleke kakhulu ukunciphisa yi greenhouse effect jikelele. Ukongeza, kuba irhasi amafutha ze battery power kwamafutha kufuneka desulfurize phambi indlela ze umbane zisekelwe kumgaqo electrochemical, akukho inkqubo yokutsha lobushushu eliphezulu, yaye ngoko ke, akukho nto phantse akukho kukhululeka-nitrogen nesulfure oxides, leyo kunciphisa ukumoshwa komoya. Kulo kuvala, platinum nangoku yinxalenye ebalulekileyo amafutha amandla ebhetri reaction electrochemical kuvala.
Okwangoku, umgangatho woshishino PT nama-0.5 ~ 0.7g / kW, kunye Toyota Mirai reactor nangoku ukubakhokela zokusela PT imalunga 0.
3g / kW. Ngenxa uphuhliso iza entsha platinum ingxubevange kunye nenkampani kuvala (umzk
, i-carbon nanowires), umxholo we-platinum uyancipha ngakumbi, kwaye inani leplatinum elisetyenziswe kwinkqubo yokulungisa i-diesel yangasemva ifezekisiwe. Ngokwezibalo, iSebe lezaMandla lase-US (DOE) lisekelwe kwiindleko zezinto eziphathekayo kwi-2016. Xa ixabiso lemveliso yebhetri yamandla efuthe lifikelela kwiiyunithi ze-100,000 / ngonyaka, malunga ne-40% yeendleko ze-reactor electrocatalytic, ngoko ukunciphisa ukusetyenziswa kwe-PT kuya kunciphisa kakhulu amandla e-reactor.
Okwangoku, i-fuel power lithium ibhetri esetyenziswa zizithuthi zorhwebo isabalulekile kwi-graphite plate reactor. Inkqubo yokwenziwa ephucukileyo iqinisekisa ukuthembeka kunye nokuqina kwe-reactor, kwaye ikwanciphisa iindleko zokuthengwa kwe-injini enkulu yefektri. Ukongeza, i-modularity ye-fuel power lithium ibhetri yenkqubo inciphisa iindleko zemveliso enkulu.
Oku ngasentla luhlalutyo olucacileyo lolwazi lwamandla amafutha e-lithium ibhetri. Kufuneka uqhubeke uqokelela amava anxulumeneyo ekusebenzeni, ukuze ukwazi ukuyila iimveliso ezingcono kwaye uphuhlisele uluntu lwethu.
