Ngophuhliso olukhawulezayo loluntu, ibhetri yethu yamandla e-lithium ikhula ngokukhawuleza. Ngoko uyaluqonda ulwazi oluneenkcukacha lwe-fuel-powered lithium battery? Okulandelayo, vumela uXiaobian akhokele wonke umntu ukuba afunde ngakumbi ngolwazi. Ibhetri yamandla e-fuel sisixhobo sokuguqula amandla.

Ngokungafaniyo nezixhobo zokugcina amandla ezifana neebhetri ze-lithium ion, ipakethe yebhetri eqhutywa ngamafutha inokuguqulwa ngokuthe ngqo kumandla ombane ngokuphendula kwe-electrochemical. Ngakolunye uhlangothi, ibhetri ye-lithium ion ihlawuliswa ixesha elide ukugcina amandla, kunye nokukhupha ukuqhuba isithuthi ngexesha lokuhamba. Ngoko ke, inqwelo yebhetri yemoto yebhetri ixhomekeke kubungakanani bepetroli kwisithuthi, oko kukuthi, kufana nomzila we-diesel oqhelekileyo, ingakanani i-hydrogen enokugcinwa kwi-hydrogen.

Ukongeza kwi-hydrogen, amafutha aqhelekileyo aquka i-methanol, i-hydrogen, i-hydrocarbons, kunye ne-carbon monoxide. Ii-oxidants zidla ngokuba yioksijini okanye umoya. Ii-electrolyte eziqhelekileyo ziquka i-phosphoric acid, i-potassium hydroxide, i-carbonate etyhidiweyo, kunye ne-ion exchange membrane.

Ibhetri yamandla e-fuel sisixhobo sokuvelisa amandla esiguqula amandla ekhemikhali kumafutha kunye ne-oxidant ibe ngamandla ombane. Ngokungafaniyo neenjini zokutsha zangaphakathi, amandla ekhemikhali kumafutha awakhutshwa ngokusabela kwe-electrochemical ngokutsha kodwa ngokusabela kwe-electrochemical, ngokusebenza okuphezulu kunye nokukhutshwa kwe-zero. Ngaphaya koko, inqwelo yebhetri yamandla epetroli inebhetri encinci yokugcina amandla ombane aseleyo kwibhetri yamandla epetroli kunye namandla afunyenwe kwibhuleki yemoto, kwaye inikezela ngombane kwimoto ngebhetri yamandla epetroli xa kuyimfuneko.

Ke ngoko, ibhetri yamandla e-lithium ineenzuzo kumgama omde xa kuthelekiswa nebhetri ye-lithium ion. Ukuveliswa kwamandla ebhetri yamandla epetroli akukhawulelwanga yiCarno loop. Ngokwethiyori, ukuveliswa kwamandla okusebenza kakuhle kunokufikelela kwi-85% ukuya kwi-90%, kodwa ngenxa yemida eyahlukeneyo ye-polarization ekusebenzeni, ukuguqulwa kwamandla okusebenza ngokufanelekileyo kwiseli yamandla e-fuel malunga ne-40% ukuya kwi-60%.

Ukuba amandla ombane aphunyeziwe, izinga lokusebenzisa amafutha lilonke linokuba phezulu ukuya kuma-80%. Ngokukhutshwa kwe-high-key ye-Toyota Fuel Power Battery Mirai kwi-2014, imboni yebhethri yamandla ehlabathi jikelele yangena kwixesha elitsha. Ipleyiti ye-titanium alloy bipolar yakwaToyota yonyusa amandla oxinaniso lwebhetri yamandla efuthe ukuya kwi-3.

I-1kW / L, kwaye iya kufikelela ku-4.0kw / L. Uxinaniso lwamandla oluphezulu lwenza isitaki sibe sincinci, sixinene kwaye kube lula ukusifaka.

Nangona kunjalo, ukubola kwepleyiti yentsimbi kubangela izinto eziphezulu kunye neendleko zonyango lwangaphezulu. Nangona kunjalo, njengexabiso lokuvuthwa kunye nemveliso yetekhnoloji, ipleyiti yensimbi ye-bipolar inokwehliswa okukhulu kwendawo yeendleko. Itekhnoloji yebhetri yamandla esibaso yeyona ndlela ilungileyo kwitekhnoloji ye-injini yokutsha yangaphakathi, emele uphuhliso lwekamva lwendlela yeemoto.

Nangona kunjalo, ukuba uqwalasela ezinye izithintelo kuphuhliso lweebhetri zamandla epetroli, uya kufumanisa ukuba iibhetri zamandla epetroli okwangoku zilungiselelwe ukuthengiswa kwixesha elizayo. Olona qikelelo lunethemba lolokuba imveliso yorhwebo yobuncinci beminyaka eyi-15 iya kusetyenziswa njengesithuthi samandla ebhetri yamafutha sisebenzisa i-hydrogen ecocekileyo njengamafutha. Nokuba uqaphela inqanaba elithile leshishini, liya kuba lixabiso eliphezulu.

Xa ibhetri yamandla e-fuel isetyenziswe njengamafutha njengamafutha, ukukhutshwa kwe-carbon dioxide kuye kwancitshiswa ngaphezu kwe-40% xa kuthelekiswa nenkqubo ye-injini ye-thermal, ebaluleke kakhulu ekunciphiseni i-greenhouse effect. Ukongeza, ekubeni irhasi yerhasi yebhetri yamandla epetroli kufuneka idesulfurize phambi kokuba iphendule kwaye ivelise umbane ngokusekwe kumgaqo we-electrochemical, akukho nkqubo yokutsha kobushushu obuphezulu, kwaye ke ngoko, akukho phantse ukukhutshwa kwenitrogen kunye nesulfure oxides, enciphisa ungcoliseko lomoya. Kwi-catalyst, iplatinam iseyinxalenye ebalulekileyo yamandla ebhetri ye-electrochemical reaction catalyst.

Okwangoku, inqanaba loshishino lwe-PT malunga ne-0.5 ~ 0.7g / kW, kunye ne-Toyota Mirai reactor isahamba phambili, kwaye ukusetyenziswa kwe-PT malunga ne-0.

3g/kW. Ngophuhliso lweplatinam entsha yealloy catalyst kunye necatalyst carrier (umz

, i-carbon nanowires), umxholo weplatinum uyancipha ngakumbi, kwaye inani leplatinum elisetyenziswe kwindlela yokulungisa idizili yangasemva ifezekisiwe. Ngokwezibalo, iSebe lezaMandla lase-US (DOE) lisekelwe kwiindleko zezinto eziphathekayo kwi-2016. Xa ixabiso lemveliso yebhetri yamandla e-fuel ifikelela kwiiyunithi ze-100,000 / ngonyaka, malunga ne-40% yeendleko ze-reactor electrocatalytic reactor, 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 komzi-mveliso we-injini oyintloko. 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.
