Isitoreji samandla e-lithium-ion kufanele sibize malini ukuze sikwazi ukusebenzisa amandla avuselelekayo kuphela? [Inganekwane]

Ososayensi e-Massachusetts Institute of Technology baye babala ukuthi yimaphi amazinga amandla okufanele agcinwe ukuze kufakwe inzuzo esikhundleni sezitshalo zamandla endabuko ngemithombo yamandla avuselelekayo. Kuvela ukuthi ngoshintsho oluphelele lwamandla avuselelekayo, amanani kufanele aguquke ukusuka ku-$ 5 kuya ku-$ 20 nge-kWh ngayinye.

Amabhethri anamuhla abiza ngaphezu kuka-$100 nge-kilowatt ngehora.

Sekuvele kukhona amahemuhemu ukuthi abakhiqizi bakwazile ukunciphisa izinga lama-dollar angu-100-120 ngehora le-kilowatt-ihora lamaseli e-lithium-ion, okungaphezu kwama-dollar angu-6 (kusuka ku-23 zloty) ngeseli kuya ebhethri lemoto eliphakathi. Amaseli e-CATL e-lithium iron phosphate yaseChina kulindeleke ukuthi abize ngaphansi kuka-$60 kWh ngayinye.

Nokho, ngokusho kwabacwaningi baseMassachusetts Institute of Technology, lokhu kusekuningi kakhulu. Uma besifuna ukusebenzisa amandla avuselelekayo kuphela futhi sigcine amandla engeziwe kumabhethri e-lithium-ion, kungadingeka ukuthi siyeke. kufika ku-10-20 $ / kWh lapho ushintsha isikhungo samandla enuzi. Ezimbonini zamandla aphehlwa ngegesi - izibalo ezisekelwe e-United States, engumkhiqizi wegesi wemvelo wesine ngobukhulu emhlabeni - izindleko zebhethri ye-lithium-ion kufanele zibe ngaphansi ngisho nangaphezulu - $ 4 kuphela nge-kWh ngayinye.

Kodwa nali ilukuluku: amanani angenhla ayacabanga ejwayelekile esikhundleni sezitshalo zikagesi ezichaziwe ngemithombo yamandla avuselelekayo, okungukuthi, izindawo zokugcina amandla ezanele ukuhlangabezana nezidingo zesikhathi eside sokuthula nokukhanya kwelanga okubi. Uma okuvuselelekayo kutholwe kukhiqiza "kuphela" amaphesenti angama-95 wamandla, ukugcinwa kwamandla kwenza umqondo wezomnotho usuvele u-$ 150 / kWh!

Cishe sesifinyelele izinga lika-$150 nge-kilowatt-hora. Inkinga ukuthi awekho amafekthri amabhethri e-lithium-ion anele emhlabeni ukuze ahlangabezane nezidingo zabakhiqizi bezimoto, ingasaphathwa eyezitolo ezinkulu zamandla. Yiziphi ezinye izinketho? Amabhethri agelezayo e-Vanadium kulula ukwakha, kodwa abiza ($100/kWh). Amathangi esitoreji noma amayunithi omoya acindezelwe ashibhile ($20/kWh) kodwa adinga izindawo ezinkulu nezimo ezifanele zendawo. Obunye ubuchwepheshe obushibhile busesigabeni socwaningo nentuthuko kuphela - silindele ukuphumelela maduze nje kuneminyaka engu-5.

Kuyafaneleka ukufunda: Kufanele kungabizi kangakanani ukugcinwa kwamandla ukuze izinsiza zishintshele kumaphesenti angu-100 wamandla avuselelekayo?

Isithombe esivulayo: Isitoreji samandla se-Tesla eduze kwepulazi lelanga le-Tesla.
