Fasahar Li-Ion: farashin rukunin yana faɗuwa da sauri fiye da hasashen

Sannu kuma, abokai!

Labarin "Lokacin lithium-ion UPS: hadarin wuta ko mataki mai aminci a nan gaba?"Mun tabo batun farashin da aka ƙera na mafita na Li-Ion (na'urorin ajiya, batura) a cikin takamaiman sharuɗɗan - $/kWh. Sannan hasashen 2020 ya kasance $200/kWh. Yanzu, kamar yadda ake iya gani daga CDPV, farashin lithium ya ragu a ƙasa da $ 150 kuma ana hasashen raguwar saurin ƙasa da $ 100 / kWh (bisa ga Forbes). Me wannan ya canza, kuna tambaya? Da farko, an rage rata tsakanin farashin batura na gargajiya da fasaha masu ban sha'awa, da kuma mafita dangane da su. Bari mu yi ƙoƙarin yin ƙididdigewa a kan yanayin wannan jirgin ruwa na Jafananci tare da batura Li-Ion.

Asalin bayanai

Muna ɗaukar bayanan farko:

• farashin farashin 200 $ / kWh daga labarinmu game da amincin wuta na lithium
• hasashen farashin 300 $/kWh daga labarin mu na 2018 "UPS da tsarin baturi..."
• Bambancin farashin da aka kiyasta tsakanin mafita na VRLA da Li-Ion shine sau 1,5-2, an ɗauka daga labarinmu na 2018 akan haɗarin wuta na lithium.

Yanzu bari mu ƙidaya

1. Rushewar da aka annabta na farashin tutoci ya yi taka tsantsan; ainihin raguwar ta fi sauri
2. Ƙarfin da ke haifar da faduwar farashin hanyoyin masana'antu ta amfani da batirin lithium-ion sune motocin lantarki: ƙarfin makamashi a cikin baturi yana karuwa, shimfidawa suna canzawa, kuma samarwa yana girma cikin sauri. Kuna iya karantawa a ciki "Marubuci bita anan"
3. Ƙididdigar ƙarfin baturi na jirgin ruwa na Jafananci ya kasance 17 MWh; muna ɗaukar nauyin farashin lithium na 2017 a cikin adadin $ 300 / kWh. Muna samun dala miliyan 5,1.
4. Dangane da ainihin farashi daga CDPV, raguwar ta kasance kusan 2% sama da shekaru 30. A farashin 2019, muna samun tanadi na kusan dala miliyan 1,5. Ba sharri ba? Ina tsammanin lokacin kera irin waɗannan jiragen ruwa, ya zama dole a loda shi da batir Li-Ion a ƙarshe, daidai kafin a fara gwajin teku.
5. Ana iya ɗauka cewa don mafita na masana'antu akan batirin lithium, raguwar farashi, karanta daidaitaccen farashi tare da jerin batirin gubar-acid, yana faruwa da sauri fiye da yadda ake tsammani. A cikin labarin 2018, kiyasin bambanci tsakanin UPS akan baturan lithium ya fi sau 1,5-2 tsada fiye da UPS na gargajiya. A halin yanzu, wannan gibin yakamata ya zama ƙarami da gangan ...

… a ci gaba…
